2. Description of the Related Art For example, there is a device as shown in FIG. 16 as a device which enables a telephone conversation underwater (first conventional example). First, the mouse mask for diving 10
1, there is a regulator connecting portion 103 attached to the mouse mask 101, and a regulator (not shown) is attached to the regulator attaching portion 103. And the regulator is via a hose (not shown)
The diver 105 is connected to a cylinder mounted on the back. The mouse mask 101 is the mouth part 1 of the diver 105.
It is detachably attached so as to cover 05a. A microphone 107 is installed in the mouse mask 101, and a speaker 109 is attached to the ear portion 105b of the diver 105. The microphone 107
The speaker 109 is connected to a communication device (not shown) via cables 111 and 113. It should be noted that this communication device is carried by a diver to another place. Then, using the microphone 107 and the speaker 109, for example, a call is made with another diving person or with a worker on board.

FIG. 17 shows the structure of another device (second one).
Conventional example). In the case of this device, a bone conduction type speaker 115 is used as a speaker, and the bone conduction type speaker 115 is attached to the occipital region of the diver 105. Other configurations are the same as those shown in FIG. The bone conduction speaker 115 is used by the diver 105.
It is configured to transmit vibration directly to the eardrum through the bones of. Then, using the microphone 107 and the bone conduction type speaker 115, for example, a call is made with another diving person or with a worker on board.

Next, a third conventional example will be described with reference to FIG. This is disclosed in JP-A-3-68226. First, the diver 105 is head belt 11
The communication device 119 integrated via the
Wear it by hanging it across 5b. The communication device 119 includes an ultrasonic transmission / reception electronic circuit and a microphone 1.
21, a speaker, an ultrasonic transmitter / receiver, etc. are integrally incorporated. In addition, the microphone 121 in this case has a structure for picking up a sound by the meat conduction mechanism.
It is attached so as to be in close contact with the cheek 105c.
Then, using this communication device 119, for example, a call is made with another diving person or with a worker on board.

Next, a fourth conventional example will be described with reference to FIG. In this conventional example, in the configuration of the second conventional example,
As for the microphone, the bone conduction microphone 123 is also used.
Is to be used. The bone-conduction type microphone 123 is configured to pick up its sound through the bones of the chin of the diver 105. Then, the bone conduction type microphone 123 and the bone conduction type speaker 11
5 is used to make a call with, for example, another diving person or a worker on board.

[0006]

The above-mentioned conventional structure has the following problems. First, in the first conventional example, since the microphone 107 is attached to the mouse mask 101, the mouse mask 101 can be attached / detached at the same time that the microphone 107 can be attached / detached. However, the speaker 109 is attached / detached separately. There is a problem that it is necessary to perform complicated attachment / detachment work. Further, the diver 105 wears underwater goggles and the like in addition to the equipment shown in the drawing, and at that time, the belt is caught on the ear portion 105b or in the vicinity thereof, and the ear portion 10b
There was a risk that the equipment would be concentrated around 5b, and the work of attaching and detaching it would be complicated, and that the workability of diving work would be reduced. Since the microphone 107 is installed in the mouse mask 101, the microphone 107 is
There is also a problem that noise, for example, the operation sound of the regulator is picked up, and the quality of communication deteriorates.

In the second conventional example, the speaker 109 is used.
Since the bone conduction speaker 115 is used instead of the bone conduction speaker 115, there is an advantage that the structure around the ear portion 105b is simplified.
The annoyance of having to attach / detach separately from the attaching / detaching of 7 cannot be eliminated. Also in this case, since the microphone 107 is installed in the mouse mask 101, the microphone 107 is, for example,
There is also a problem in that the operation sound of the legulator is picked up and the quality of communication deteriorates. Further, since the bone conduction speaker 115 is also exposed, noise, such as exhaust noise, is picked up, which also causes a problem that communication quality is deteriorated. On the other hand, in the third conventional example, the communication device 119 is an all-in-one unit, but it requires detaching work separately from the mouse mask 101, and the equipment is concentrated around the ear 105b. The points that do happen are still unsolved. Furthermore, also in the case of the fourth embodiment,
The fact that the work of attaching and detaching separately from the mouse mask 101 is required remains as a problem. Also in this case, since the bone conduction type microphone 123 is exposed, there is a problem that various noises are picked up and the communication quality is deteriorated.

Further, the above problem is not limited to the communication device for diving, but the structure is complicated and the mounting is difficult because two access points are required for communication. In terms of poor communication quality, communication in noisy environments on the ground (for example, communication at construction sites, communication by aircraft mechanics, etc.), various communication by people with hearing impairments, etc. , There was a similar problem, and no novel communication device that could solve it was realized. More specifically, in a noisy environment, the conventional communication device picks up various noises as they are, so that there is a problem that important communication is significantly impaired. Further, it is impossible for a person with hearing impairment to listen to stereo sound, for example.

The present invention has been made on the basis of the above points, and an object of the present invention is to provide a communication device which does not require a large number of attaching / detaching operations and has a simple structure and enables good communication. To provide.

[0010]

In order to achieve the above object, a communication device according to the present invention outputs an electric signal current or an electric signal by inputting vibration and a clenching portion for a user to clench with a tooth. By virtue of this, a drive section that outputs vibration, a support transmission section that connects the above-mentioned clasping section and the driving section and mutually transmits vibration between the clenching section and the driving section, and a communication circuit connected to the driving section, It is characterized by having. At that time, a pair of clenching parts for the user to clench with the left and right teeth are provided, and

Further, it is conceivable that a pair of driving portions is provided and the pair of driving portions are connected to the pair of clasping portions via separate support transmission portions. Further, it is conceivable that one bite tightening portion is connected to one driving portion via the support transmission portion. Further, it is conceivable to provide two driving units to enable bidirectional simultaneous communication.

It is also conceivable that the communication device according to the second aspect is integrally attached to the diving mouse mask, and the mouse mask is mounted by clenching the pair of clasping portions with the left and right teeth. It is also conceivable to use the communication device according to claim 3 for listening to stereo sound. Further, it is conceivable that the communication device according to claim 1 or claim 2, or claim 3 or claim 4 is built in an arbitrary case, and the bite tightening portion can be exposed by removing the cap.

[0012]

In the communication device according to the present invention, so-called bone conduction is utilized for communication.

The drive unit outputs an electric signal due to the vibration, and the electric signal is processed and output by the communication circuit. Conversely, the signal received by the communication circuit is processed by the communication circuit and transmitted to the driving unit. In the drive section, vibration is generated by the electric signal, and the vibration is transmitted to the clenching section through the support transmission section, and then transmitted to the auditory sense through the bone and is recognized as voice. It should be noted that the number of the tightening portions, the driving portions, and the support transmission portions and the connection configuration are not particularly limited.
It may be appropriately determined so as to correspond to the communication system to be applied.

When the above communication device is applied as a diving communication device, it is attached integrally to a mouse mask for diving. That is, by attaching and detaching the mouse mask, the diving communication device is attached and detached at the same time. Then, the mouse mask is airtightly attached by clenching the pair of clenching portions. The communication function is the same as that described above. It may also be configured for listening to stereo sound. It should be noted that there are various other uses as well, and it is particularly suitable for communication in a noisy environment. In addition, the use of the case and the cap improves convenience in carrying the device.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS The first embodiment of the present invention will be described below with reference to FIGS.
An example will be described. In this embodiment, the present invention is applied to a diving communication device. First, the pair of bite tightening portions 1
There are a and 1b, and these clenching portions 1a and 1b are clenched with the left and right upper and lower back teeth of the diver 19 (shown in FIG. 3). The pair of bite tightening portions 1 a and 1 b are integrated via the support transmission portion 3. The support transmission portion 3 has a substantially U-shape, and is provided with the pair of bite tightening portions 1a and 1b at both ends thereof. A drive unit 5 is provided at an intermediate portion of the support transmission unit 3. The bite tightening portions 1a, 1

The drive unit is a so-called electromagnetic drive unit, and is composed of a U-shaped iron core 7, a coil 9 wound around the iron core 7, and a permanent magnet 11 arranged between the iron core 7. It is configured. For example, when a voice current as an electric signal flows through the coil, the change in magnetic flux causes the permanent magnet to vibrate. The vibration is transmitted to the pair of clenching portions 1a and 1b via the support transmission portion 3, and from there, is further transmitted to the auditory sense through the teeth of the submersible person 19 and the bones of the jaw. On the contrary, when the voice of the diver 19 is output, it is transmitted to the pair of clenching portions 1 a and 1 b via the teeth of the diver 19 and then transmitted to the permanent magnet 11 via the support transmission portion 3. As a result, when the permanent magnet 11 vibrates,
The magnetic flux passing through the iron core 7 changes, and as a result, a voice current as an electric signal flows through the coil 9.

As shown in FIG. 2, the device having the above construction is integrally attached to the mouse mask 13 for diving. A regulator mounting portion 15 is attached to the mouse mask 13, and the regulator mounting portion 1
A regulator (not shown) is attached to 5. Then, it is connected to a cylinder (not shown) via this regulator. In addition, the mouse mask 13 has a mounting portion 17a,
The device 17 shown in FIG. 1 is fixed to the mouse mask 13 by attaching the support transmission portion 3 to the attachment portions 17a and 17b.
In addition, as shown in FIG. 3, the diving person 19 bites and tightens the pair of clenching portions 1a and 1b, so that the mouse mask 13
Will come into close contact with the face of the diver 19 and thereby maintain hermeticity. The bite tightening portion 1a,
Regarding the airtightness maintaining function according to 1b, JP-A-2-141
This is described in detail in Japanese Patent No. 387.

Next, the configuration of the communication circuit 21 will be described with reference to FIG. First, the drive unit 5 already described is connected to the transmission / reception switch 25 of the communication circuit 21 via the cable 23. The electric signal from the drive unit 5 passes through the transmission / reception switch 25, the filter 27, and is amplified by the audio signal amplifier 29. Then, after being modulated by the modulator 31, the output amplifier 35 passes through the filter 33.
It is amplified by and is input to the transmission / reception switch 37, and from there, it is transmitted to other divers, ships, etc. via the transmission / reception sensor 39. The transmission / reception switch 25, 37
A transmission / reception changeover switch 42 is inserted between the two.

On the other hand, the signal input via the transmission / reception sensor 39 is input to the preamplifier 41 via the transmission / reception switch 37 and amplified. Then, the signal is demodulated by the demodulator 43, passes through the filter 45, and is input to the audio output amplifier 47. The transmission / reception switch 25 is amplified there
Is input to the drive unit 5 via. The communication circuit 21 having the above-described configuration may be disposed in the vicinity of the drive unit 56 so as to be built in the mouse mouse 13 or the diver 19.

The operation will be described based on the above configuration. First, the diver 19 wears necessary equipment (not shown) and wears the mouse mask 13, and at that time, the pair of clenching portions 1a and 1b are clenched with left and right upper and lower back teeth. As a result, the call can be made underwater and the airtightness of the mouse mask 13 can be maintained. By the way, when talking to another diver or a ship underwater, the user normally speaks with the pair of clenching portions 1a and 1b clenched. The sound generated by it is the Diver 1
It is transmitted to the pair of clasping portions 1 a and 1 b through the bones of 9, such as teeth and jaw bones, and from there, is transmitted to the drive portion 5 through the support transmission portion 3. In this drive section, a voice current is generated by the operation already described, and the current signal is input to the communication circuit 21. Then, the signal is output to other divers and the ship via the communication circuit 21.

On the contrary, when a signal from another diver or a ship is received and recognized as a voice, the flow is the reverse of the above. That is, the communication circuit 21 receives signals from other divers and the ship, and inputs them to the drive unit 5. In the drive unit 5, vibration is generated by the signal, and the vibration is input through the support transmission unit 3 and the pair of clenching units 1a and 1b, and further transmitted to the auditory sense through the teeth of the diver 19 and the bones of the jaw. , Thereby recognizing voice.

Next, a second embodiment will be described with reference to FIG. In the case of this embodiment, the drive section 5 uses an electrostrictive oscillator 49, which is built in by a waterproof structure. Therefore, the same effect as in the case of the first embodiment can be obtained. The electrostrictive oscillator 49 may be, for example, one formed by laminating two piezoelectric ceramic thin plates (bimorph type oscillator, for example, manufactured by Fuji Ceramics Co., Ltd.). This is such that when a voltage is applied, one element expands and the other element contracts, which causes vibration, and conversely, when vibration is input, a voltage is generated.

Next, a third embodiment will be described with reference to FIG. In the case of this embodiment, a resonance box 51 having a waterproof structure is installed around the drive unit 5 so as to expand the vibration and prevent bubble noise from being picked up. Therefore, it is possible to achieve the same effect as that of each of the above-described embodiments and to enable better communication. As an example of attaching the mouse mask 13 integrally, in addition to the case of diving as described above, there are conceivable examples of a doctor's surgical mask, a dust mask, and the like. Communication under the environment is also possible.

Next, a fourth embodiment will be described with reference to FIG. In this case, an example in which the present invention is applied as a communication device in a noisy environment (for example, a factory, a construction site, an airfield) is shown.

Further, the communication circuit 21 has a structure as shown in the drawing, and the same parts as those shown in FIG. 4 are designated by the same reference numerals. With such a configuration, a good call can be performed in a noisy environment (for example, when earplugs are used in a noisy environment).

Next, a fifth embodiment will be described with reference to FIGS. In this case, the present invention is applied as a communication device (reception device) for listening to stereo sound. First, there is a pair of left and right bite tightening portions 1a and 1b, and these bite tightening portions 1a and 1b are connected to drive portions 5a and 5b via support transmission portions 3a and 3b, respectively. The drive units 5a and 5b may have various configurations as described in the above embodiments. Further, as shown in FIG. 9, a part of the drive parts 5a, 5b and the support transmission parts 3a, 3b are held in a housing 53 made of a material such as rubber having an appropriate internal loss. .

The audio signals input from the left and right are adjusted by the volume adjuster 55, amplified by the audio output amplifier 57, and input to the drive units 5a and 5b separately for the left and right. Then, it is transmitted to the pair of clasping portions 1a and 1b through the support transmitting portions 3a and 3b, and from there, is transmitted to the left and right hearing through the jaw bones and the like. With this configuration, for example, a person with hearing impairment (for example, a person who cannot hear only one ear) can enjoy the so-called stereo sound, and in other cases, the stereo sound cannot be heard. It becomes possible to enjoy in a better condition.

Next, a sixth embodiment will be described with reference to FIG. This shows an example in which the number of clenching parts is one. Communication is possible even with a single clenching part, without considering incorporation into a mouse mask for diving. First, one bite tightening portion 1 is provided, and this bite tightening portion 1 is connected to a drive portion 5 via a support transmission portion 3. A communication circuit 21 is connected to the drive unit 5, and a battery 61 as a power source and an antenna 63 are further connected. Further, the whole is contained in a fountain pen type case 65, and by removing the cap 67, the bite tightening portion 1 can be exposed. The detailed structure of each part is the same as that manufactured in each of the embodiments. With such a configuration, the bite tightening portion 1
