The panel speaker has a characteristic that the acoustic output is hardly dependent on frequency
and radiates sound in an omnidirectional manner. In addition, the panel speaker has a
characteristic that power loss due to distance is very small and the sound can reach far as
compared with a normal speaker.
[0003]
Conversely, panel speakers tend to make louder sounds than commonly used speakers and
handsets. The existing telephones equipped with panel speakers do not have means for
preventing sound emission such as careless ringtones and alarms from panel speakers in
advance, and the user may feel uncomfortable because the volume of the speakers is too high.
high.
[0004]
2. Description of the Related Art Conventionally, there is a telephone set that can be used safely
without the user feeling discomfort with respect to the volume (see, for example, Patent
Document 1). When the telephone detects an incoming call, it determines whether or not to be in
the reception standby state, and emits a ring tone at a volume lower than the set volume
regardless of the set volume except in the reception standby state. Japanese Patent Laid-Open

processing circuit 105, microphone 106, receiver 107, speaker 109, sound generation circuit
111, display 113, PLL circuit 114, A key circuit 115, a ROM (read-only memory) 116, and a RAM
(random-access memory) 117 are provided.
[0014]
The antenna 101 exchanges radio signals, for example, between the portable radio telephone
100 and a base station or a master.
The RF / IF unit 102 performs frequency conversion of a radio signal transmitted and received
by the antenna 101.
The modulation / demodulation unit 103 modulates the transmission signal from the portable
wireless telephone 100 or demodulates the received signal to the portable wireless telephone
100.
The digital signal processing circuit 104 converts a digital transmission signal into an analog
transmission signal, and converts an analog reception signal into a digital reception signal.
The digital signal processing circuit 104 also performs, for example, preprocessing necessary for
modulation in the case of a transmission signal, and necessary preprocessing for audio signal
processing in the case of a reception signal.
[0015]
The audio signal processing circuit 105 decodes the digital audio signal output from the digital
signal processing circuit 104 and converts it into an analog audio signal.

Further, the audio signal processing circuit 105 converts an analog audio signal input from the
microphone 106 into a digital signal by performing adaptive differential pulse code modulation
(ADPCM) or PCM conversion.
The audio signal processing circuit 105 outputs a D / A (digital-to-analog) converted analog
signal to a normal receiver 107 or panel speaker 108.
[0016]
The receiver 107 outputs the voice (listening sound) of the other party of the call, and the panel
speaker 108, for example, includes a ringing tone, an alarm sound generated when the battery
level of the portable wireless telephone 100 decreases, music linked to moving pictures, etc.
Output
[0017]
The panel speaker 108 vibrates a panel by vibrating a vibrator arranged in the vicinity of the
panel, and generates a sound from the panel.
The panel speaker 108 is connected to, for example, the display 113, and the display screen
vibrates to generate a sound from the display screen.
The panel speaker 108 can generate a large volume compared to the normal speaker 109 and
the receiver 107 because the sound reaches far compared to the normal speaker 109 and the
receiver 107 and is omnidirectional. Sound leakage is easy.
[0018]
Further, the panel speaker 108 generates a sound of the type output by the receiver 107, and
generates a sound of the type output by the speaker 109.
That is, the panel speaker 108 serves as both the receiver 107 and the speaker 109.
11-05-2019

For example, the panel speaker 108 outputs a voice from the other party as the receiver 107,
and outputs as a speaker 109 a ring tone and an alarm sound for causing the user to make a
battery shortage. Alternatively, the receiver 107 and the speaker 109 may be removed and only
the panel speaker 108 may be installed in the portable wireless telephone 100 as a substitute for
these.
[0019]
The control circuit 110 executes various modes with the output signal of the key circuit 115 in
accordance with the program written in the ROM 116, and exchanges control data with the
digital signal processing circuit 104 and various data with the RAM 117. Then, processing such
as call origination or call reception with the base station is performed. The operation of the
control circuit 110 will be described later with reference to FIG. 3, FIG. 4 and FIG.
[0020]
The sound generation circuit 111 outputs a sound source signal such as a ring tone, an alarm
sound, or music based on the control of the control circuit 110. The volume setting circuit 112
controls the set volume by the control circuit 110 to cause the normal receiver 107, the panel
speaker 108 or the normal speaker 109 to generate a receiving sound or a ringing tone at the set
volume. Also, the volume may be set by different volume setting circuits (not shown) of the
receiver 107 and the speaker 109.
[0021]
The display 113 displays a moving image or a still image. In addition, the panel speaker 108 is
installed in the display 113, the display screen of the display 113 vibrates, and a sound is
generated from the display screen.
[0022]
The PLL circuit 114 changes the reception frequency and the transmission frequency of the RF /
IF unit 102 based on an instruction from the control circuit 110.

[0023]
The key circuit 115 is for the user to operate the portable radio telephone 100, and includes, for
example, an on-hook / off-hook key, a ten key, an up / down key, and a function key.
The volume setting of the ring tone, the alarm sound, etc. is performed by the up / down key by
setting the volume setting mode of the ring tone or the alarm sound by the function key. Set up
the listening sound with the up-down key during the call. The set volume is stored in the RAM
117.
[0024]
The ROM 116 stores a program to be executed by the control circuit 110. The RAM 117 also
stores data and the like used in programs executed by the control circuit 110.
[0025]
Although this embodiment has been described using a portable radio telephone as an example of
the telephone of the present invention, the present invention is not limited to a portable radio
telephone, and any telephone having a panel speaker can be applied to any telephone. be able to.
[0026]
(Level of Volume Setting) Next, an example of the operation of the mobile wireless telephone 100
will be described with reference to FIGS. 2 and 3.
In this example, use of the panel speaker is enabled only when the portable radio telephone is set
to the volume level dedicated to the panel speaker, and use of the panel speaker is disabled
except for this volume setting.
[0027]
11-05-2019
7
By managing the use of the panel speakers in this way, the user recognizes whether or not the
volume level is set exclusively for the panel speakers, and the user may feel uncomfortable
because the volume of the speaker is too high. Will disappear.
[0028]
FIG. 2 is an example of the sound volume setting mode setting screen shown on the display unit
113.
The volume setting mode in FIG. 2 includes two types of modes, a special volume mode 201 and
a normal mode 202. When the special volume mode 201 is set, a sound is output from the panel
speaker 108. When the normal mode 202 is set, a sound is output from the receiver 107 or the
speaker 109.
[0029]
As shown in FIG. 2, the special volume mode 201 has, for example, three volume setting levels,
and the normal mode 202 has, for example, five volume setting levels. In these volume setting
modes, the volume size is set according to the size of the indicator shown in FIG. In the example
of FIG. 2, the level 1 is the smallest in volume, the volume gradually increases as the levels 2 and
3 are advanced, and the volume in the special volume 3 is the largest. It is desirable that the
special volume 1 which is the minimum volume of the special volume mode 201 be set to a
volume at which the user does not feel discomfort to the ear.
[0030]
Also, the volume setting mode screen may be such that, for example, a mode can be selected first
from either the special volume mode 201 or the normal mode 202, and then the volume level in
the mode can be set.
[0031]
Next, the operation of the mobile phone radio 100 will be described with reference to the
flowchart of FIG.

[0032]
In addition to exchanging voices with other parties, existing telephones have various functions
such as exchanging mail, viewing music or television, and notifying of a battery shortage.
Therefore, the existing telephone does not handle only the ring tone (or music or message
notifying an incoming call), the voice of the other party at the time of the call like a conventional
telephone, but it is at the time of viewing a mail ring tone, music or television. Handling different
sounds of various applications such as voice, alarm sound at the time of battery shortage.
[0033]
The control circuit 110 starts processing for outputting a received sound, a ringing tone, an
alarm sound, or music from at least one of the receiver 107, the panel speaker 108, and the
speaker 109 (step S301).
The control circuit 110 determines whether the volume set by the user is set to the special
volume mode 201 with reference to the RAM 117 (step S302). If the control circuit 110
determines that the special volume mode 201 is set, the process proceeds to step S303. If it is
determined that the special volume mode 201 is not set, the process proceeds to step S304.
[0034]
In step S303, the control circuit 110 causes the sound generation circuit 111 to generate a
sound and causes the panel speaker 108 to output the sound at the volume set in the special
volume mode 201. In step S304, the control circuit 110 causes the sound generation circuit 111
to generate a sound and causes the receiver 107 or the speaker 109 to output a sound at the
volume set in the normal mode 202.
[0035]
Further, the control circuit 110 may control the display unit 113 to display the current volume
11-05-2019

setting mode or the currently available speaker type. In this way, the user can easily check at any
time whether or not the panel speaker can be used by observing the display screen.
[0036]
(Examination of panel speaker) In the following example, the panel speaker is exposed at a
position visible to the user, and further, when the panel speaker is close to the user's ear, sudden
loud volume is not output from the panel speaker Control. Ringtones and alarm sounds often
occur suddenly when the user does not expect, and such sudden occurrences that the user does
not expect are likely to surprise and dislike the user. The fact that the panel speaker is exposed at
this position indicates that the vibrating surface outputting the sound of the panel speaker is
facing the outside. In this state, a loud sound is likely to be emitted from the panel speaker with
the medium in the air.
[0037]
An example of this is control when a ringing tone or alarm sound is generated that is passive
(that is, not caused by an action performed by the user) and is active (ie, caused by an action
performed by the user) Such control is not performed because there is no "sudden sound".
[0038]
First, the case of a foldable portable radio telephone will be described with reference to FIG.
[0039]
The control circuit 110 starts processing for outputting a ringing tone or an alarm tone from the
panel speaker 108 among the receiver 107, the panel speaker 108, and the speaker 109 (step
S401).
The control circuit 110 determines whether a ringing tone or an alarm tone needs to be emitted
(step S402).
If it is determined that the control circuit 110 needs to sound, the process proceeds to step S403,
and if it is determined that it is not necessary to sound, the process proceeds to another process.
11-05-2019
10
In step S402, the control circuit 110 may periodically determine at a certain time interval
acquired by a timer (not shown), or the control circuit 110 receives an instruction to ring a ring
tone or an alarm sound. In this case, the process may be set to proceed to step S403.
[0040]
In step S403, the control circuit 110 determines whether the panel speaker is exposed. In a
general foldable portable radio telephone, the fact that the panel speaker is exposed corresponds
to the state in which the main body of the portable radio telephone is open (the state in which
the fold panel is open). However, in the present embodiment, it is not essential to change the
control depending on whether the telephone main body is open or not, and the control is
changed depending on whether the panel speaker is likely to be exposed and close to the user's
ear. Is essential.
[0041]
If the control circuit 110 determines in step S403 that the panel speaker is exposed, the process
proceeds to step S404, and on the other hand, it is not exposed (for example, the telephone main
body is closed, that is, the folding panel is closed). If it is determined that there is a problem, the
process proceeds to step S405. In step S404, for example, the control circuit 110 causes the
volume setting circuit 112 to set the volume of the panel speaker 108 to be gradually increased.
Of course, it is not limited to gradually increasing the volume. It is important that the volume of
the sound initially generated from the panel speaker 108 be small. This volume is a volume that
does not cause surprise or discomfort to the user who put the panel speaker 108 in his ear even
if the sound is suddenly emitted, and may be preset by the user. In addition, the volume of the
sound that is first generated from the panel speaker 108 is set to a volume that does not cause
anyone to be surprised or offensive at first when the product is shipped. As described above,
since the panel speaker 108 initially generates a low volume sound, the user is not surprised or
uncomfortable even if the sound is suddenly emitted.
[0042]
In step S405, the control circuit 110 causes the volume setting circuit 112 to generate a sound at
the volume set by the user. The panel speaker 108 may generate a loud sound from the
beginning. In this case, since the panel speaker 108 is not exposed, the sound does not reach the
11-05-2019
11
user's ear directly from the panel speaker 108 even if it sounds suddenly. It does not.
[0043]
<Distance between Panel Speaker 108 and Ear> In the following example, when the distance
between the panel speaker 108 and the user's ear is short, sudden loud volume is not output
from the panel speaker. FIG. 5 shows a block diagram of the telephone 500 in this case. The
telephone set 500 is obtained by adding an optical sensor 501 to the portable wireless telephone
set 100 of FIG.
[0044]
The optical sensor 501 is a device for detecting the presence of an object within a certain
distance. In the case of the portable wireless telephone 500 according to the present
embodiment, when the distance from the panel speaker 108 to the ear is equal to or less than a
certain distance, the optical sensor 501 determines that the panel speaker 108 is positioned near
the user's ear. When it is judged in this way, the sensitivity of the optical sensor 501 is adjusted
so that the ear is located in a place where it is surprised by the sudden sound from the panel
speaker. The sensitivity may be set to be adjustable by the user. Also, at the time of product
shipment, the above-mentioned statistically determined volume is set to such a sensitivity that no
one is surprised or offended statistically.
[0045]
Next, an example of the operation of the mobile wireless telephone 500 will be described with
reference to FIG. The same steps as those in the flowchart shown in FIG. 4 carry the same
reference numerals and the explanation thereof will be omitted.
[0046]
In step S402, when the control circuit 110 determines that the ringing tone or the alarm sound
needs to be emitted, the process proceeds to step S601, and when it is determined that the
ringing need not be performed, the process proceeds to another process.
11-05-2019
12
[0047]
In step S601, the optical sensor 501 determines whether the panel speaker 108 is positioned
near the user's ear, and if it is determined that the panel speaker 108 is positioned near the
user's ear, the process proceeds to step S404. If the determination is not made, the process
proceeds to step S405.
[0048]
<Others> When the transmittable screen is displayed on the display screen of the display 113,
step S403 ("panel open") and step S404 or step S601 ("optical sensor, panel speaker 108 It may
be made to correspond to "determining whether it is located near the user's ear" and step S404.
That is, when the call enable screen is displayed, the ring tone and the alarm sound are made
smaller.
The callable screen is, for example, a call history screen, a call history screen, an address book,
and the like. According to the embodiments described above, the user adjusts the volume to
generate sound from the panel speaker, and whether or not the panel speaker is exposed (or
whether the panel speaker is close to the user's ear) Can be emitted at an appropriate volume
without causing the user to feel uncomfortable.
[0049]
The present invention is not limited to the above embodiment as it is, and at the implementation
stage, the constituent elements can be modified and embodied without departing from the scope
of the invention. In addition, various inventions can be formed by appropriate combinations of a
plurality of constituent elements disclosed in the above embodiment. For example, some
components may be deleted from all the components shown in the embodiment. Furthermore,
components in different embodiments may be combined as appropriate.
