DESCRIPTION JPH0629296
[0001]
BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an
acoustic device for listening at an appropriate volume in a hall.
[0002]
2. Description of the Related Art In a hall provided with a plurality of audience seats, a stage and
a plurality of sound generating devices, a plurality of speakers are used to listen to sounds such
as movies and music to be staged. Often, the structure of the hall is designed to be able to listen
well from any seat
[0003]
However, the present situation is that it is impossible to listen to the last row of seats, to adjust
personal hearing and preferences.
In addition, there is a facility that amplifies the audio signal directly from the tape or record and
supplies it with a headphone etc. for those who are deaf or hard to listen. However, the sound
collected by the microphone for recording may be supplied by the headphone or the like. In such
an auxiliary sound device, when listening with an earpiece type speaker such as a headphone, in
the conventional method, the sound spreads in a horizontal row generally called binaural, and
the three-dimensional effect with depth before and after the clothing is It will be lost. In addition,

even when the person is not deaf, it often feels that the volume is too high, and at present it is
difficult to solve these.
[0004]
An object of the present invention is to provide an audio device which provides a volume suited
to the individual preferences of the deaf or the listener and which does not impair the sense of
reality of the voice.
[0005]
SUMMARY OF THE INVENTION The sound device of the present invention is a hall equipped
with a plurality of audience seats, a stage and a plurality of sound generating devices, in a wellbalanced place for listening to sound. Place a life-size model of a human head, place microphones
at positions corresponding to both tympanic membranes of the model, and supply voices
collected by the microphones to each audience seat, and at each audience seat volume It is
characterized in that it can be adjusted.
[0006]
As means for supplying the voices collected by this microphone to each passenger seat, each
voice is amplified by an amplifier, a plurality of headphones etc. are connected to the output, and
the output from the amplifier at each hand It can be realized by inserting an attenuator between
the and headphones.
Also, it is possible to use a wireless communication means in which the voice collected by the
microphone is connected to a transmitter having a modulator such as FM or AM, and the
headphone is provided with a dedicated receiver and a volume controller. Economical without the
need for many wires for connection
[0007]
[Operation] The device of the present invention can collect the sound passing through the
structure close to the actual human ear, obtain the sound signal which does not impair the sense
of presence, and adjust it to the volume of the preference.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENT FIG. 1 shows an embodiment of the
present invention.
This acoustic device is a model of a human head with a full-size view at a well-balanced location
for listening to voices in a hall 8 provided with a plurality of audience seats 10, a stage 9 and a
plurality of voice generating devices 11. (Dummy head 7) is placed, microphones 1a and 1b are
placed at positions corresponding to both tympanic membranes of the dummy head 7, and the
voices collected by this microphone are supplied to the respective seats by means of the
respective voices. Is connected to the input of the amplifier 3 by the electric wire 2, and a
plurality of headphones 5 are connected to its output, and the attenuator 6 is inserted between
the output from the amplifier and the headphone 5 at the hand of each seat
[0009]
FIG. 2 shows another embodiment of the present invention.
This acoustic device is a model of a human head with a full-size view at a well-balanced location
for listening to voices in a hall 8 provided with a plurality of audience seats 10, a stage 9 and a
plurality of voice generating devices 11. (Dummy head 7) is placed, microphones 1a and 1b are
placed at positions corresponding to both tympanic membranes of the dummy head 7, and the
voices collected by this microphone are supplied to the respective seats by means of the
respective voices. Is connected to the modulator of the transmitter 2a provided near the dummy
head 7, the receiver 2c provided at the hand of each seat by the radio wave 2b, and the
attenuator 6 between the output from the demodulator and the headphone 5 Is inserted.
[0010]
Effect of the Invention As described above, according to the present invention, an audio device
capable of listening at any desired volume without impairing the presence of three-dimensional
sound, regardless of the seat. Can be provided.
