[0023]
Next, the assembly procedure of the speaker fixing device 1 for portable devices will be
described.
[0024]
First, the small speaker 2 is positioned in the speaker chamber 8 of the speaker mounting
portion 6 of the socket 3, and the small speaker 2 is inserted from above the speaker chamber 8
as shown in FIGS. 3 (a) and 3 (b). Then, the elastic locking claws 11 are elastically deformed in
the outward direction of the speaker accommodation chamber 8 and the insertion of the small
speaker 2 is permitted.
Then, when the bottom surface of the small-sized speaker 2 strikes the speaker receiving portion
10 of the speaker accommodation room 8, the insertion of the small-sized speaker 2 beyond this
is blocked.
When the small speaker 2 is inserted to this position, the elastically deformed elastic locking
projection 11 is elastically returned and deformed and is locked to the outer peripheral edge of
the upper surface of the small speaker 2.
01-05-2019

Thereby, the small speaker 2 is mounted on the speaker mounting portion 6 of the socket 3.
[0025]
Next, one connector 7 of the socket 3 to which the small speaker 2 is attached is aligned with the
upper position of the other connector 4 fixed to the mounting substrate 21, and the other
connector 4 is inserted into the insertion hole 15 of the one connector 7. When the contact
projection 22 of the second connector 4 is inserted, the contact projection 22 of the other
connector 4 is held in contact with the contact portion 14 of the one connector 7 to be in
contact.
Thereby, both connectors 4 and 7 are electrically connected.
[0026]
In addition, when the contact projection 22 of the other connector 4 is completely inserted into
the insertion hole 15 of the one connector 7, the lock claw portion 16 of the one connector 7 is
locked in the locking groove 23 of the other connector 4 .
As a result, both connectors 4 and 7 are completely fitted to complete the assembly.
[0027]
In this speaker fixing device 1 for portable devices, when mounting the small speaker 2 on the
mounting substrate 21, the small speaker 2 is inserted into the speaker mounting portion 6 of
the socket 3 by insertion, and one connector 7 of the socket 3 is mounted. It suffices to be fitted
to the other connector 4 on the mounting substrate 21 side, and the electrode 5 may simply be
exposed to the speaker 2. Therefore, the assembly work of the small speaker 2 on the mounting
substrate 21 can be performed extremely easily, and the structure of the small speaker 2 is also a
simple structure. Further, in the stage before assembling the small speaker 2 to the mounting
substrate 21, it is not necessary to process or process the small speaker 2 as in the conventional
01-05-2019

example. Furthermore, since the socket 3 has the speaker mounting portion 6 and the one
connector 7 separated and integrally provided at another position, each portion can be made
extremely simple.
[0028]
Further, in the speaker fixing device 1, when the one connector 7 of the socket 3 is fitted to the
other connector 4 on the mounting substrate 21 side, the speaker mounting portion 6 of the
socket 3 floats above the mounting substrate 21. Since it arrange ¦ positions, the vibration from
the attachment board 21 is not directly transmitted to the small speaker 2, and the small speaker
2 becomes strong to a vibration, and durability of the small speaker 2 improves.
[0029]
Further, a speaker accommodating chamber 8 for accommodating the small speaker 2 is
integrally formed in the speaker attaching portion 6 of the socket 3, and the entire
circumferential surface of the small speaker 2 accommodated in the speaker accommodating
chamber 8 is covered with the speaker attaching portion 6 Therefore, the entire circumferential
surface of the small speaker 2 is reliably protected by the speaker mounting portion 6, and the
small speaker 2 does not receive an external pressure directly. From this point as well, the
durability of the small speaker 2 is more Improve further.
[0030]
Further, in the state where one connector 7 and the other connector 4 are fitted, lock means 16
and 23 for locking both connectors 4 and 7 are respectively provided, so in addition to the
connecting force between both connectors 4 and 7 Thus, both connectors 4 and 7 are securely
fixed by the locking means 16 and 23.
Therefore, the socket 3 is firmly fixed to the mounting substrate 21.
Furthermore, the pair of terminals 12 and 12 of the socket 3 have a spring property, and the
spring property of each terminal 12 reliably holds the electrical contact with the electrodes 5 of
the small speaker 2.
[0031]

According to the embodiment, the small speaker 2 has the shape of a flat disk, but may have a
flat rectangular shape, regardless of the shape.
[0032]
As described above, according to the invention of claim 1, when assembling the speaker to the
mounting substrate, the speaker is mounted to the speaker mounting portion of the socket, and
one connector of this socket is the other connector And the speaker can be simply exposed to the
contact points, so that the assembly work of the speaker on the mounting substrate can be
performed extremely easily and the structure of the speaker can be simplified. it can.
[0033]
According to the second aspect of the invention, since the speaker mounting portion of the
socket is disposed above the mounting substrate, the vibration from the mounting substrate is
not directly transmitted to the speaker.
As a result, the speaker is resistant to vibration, and the durability of the speaker can be
improved.
[0034]
According to the third aspect of the invention, since the entire peripheral surface of the speaker
is covered with the speaker mounting portion of the socket, the speaker can be reliably protected
by the speaker mounting portion of the socket.
As a result, the speaker is less likely to receive the external pressure directly, and the durability
of the speaker can be further improved.
[0035]
According to the invention of claim 4, since the one connector and the other connector are also
fixed by the locking means, the socket can be firmly fixed by the mounting substrate.
