Abstract

<P>PROBLEM TO BE SOLVED: To solve the problem that, since a radio head set is conventionally configured so that a speaker part, a microphone part and a circuit part are integrated to a single body so as to be used by mounting this head set on the auricle, a sense of incompatibility is generated at the time of mounting it, and a fatigue follows in mounting it for a long time, and no environmental sound reaches the ear at the speaker-mounted side, and it is impossible to quickly avoid any danger as a result. <P>SOLUTION: A wearable voice receiver has a separate speaker part and circuit part mounted on a ring, and a microphone part is mounted on a wrist. A portable telephone, a fixed telephone and a personal computer or the like are used for relaying a signal for communication, and they are connected to the wearable voice receiver by radio waves. While the wearable voice receiver is being always worn, the speaker is brought close to the ear hole by covering the ear with a palm only when the receiver is used. The microphone and the circuit for communication can be mounted on the wrist part of the same hand. <P>COPYRIGHT: (C)2005,JPO&NCIPI

Description

  The present invention relates to a voice communication device that can be always worn on the body without a sense of incongruity.

Conventionally, for example, a wireless headset as shown in FIG. 4 is generally used as a wireless interface for voice communication between a mobile phone, a fixed phone, a personal computer, or the like and a human. In FIG. 4, 11 is a speaker unit, 12 is a microphone unit, and 13 is a circuit part including a transmission / reception unit and a speaker drive unit. The speaker unit 11 is mounted on the ear so that the microphone unit 12 is at the mouth. However, in such a structure, if it is always worn, there is a sense of incongruity in wearing itself, and there is also a problem of fatigue for long-time wearing. Furthermore, since the environmental sound cannot be heard from the ear on the side where the wearer is wearing, there is a problem in that the life avoidance is delayed because the position of the sound generation source cannot be specified and the risk avoidance is delayed.
In addition, there is a method in which a wristwatch-type vibration actuator is attached and communication is performed by bone conduction as disclosed in the following “Patent Document 1”. In this method, there is a limit to the application target for the use of bone conduction. On the other hand, in the following “Patent Document 2”, although it is a wearable communication device, the radio wave oscillation source requires a separate facility, and this method also has a limited range of application.

(First embodiment)
FIG. 1 shows an audio signal receiving apparatus as a first embodiment according to the present invention. In FIG. 1, a light receiving device 21 that receives infrared rays, a driving circuit 22 for driving a speaker, and a mounting substrate 23 on which the driving circuit 22 is mounted are bonded and integrated on the surface of a coin battery 24 to form an audio signal receiving unit. . This audio signal receiving unit is bonded to the outer surface of the ring 25 on the part that becomes the back of the hand when the ring is worn. In the above example, the case where a coin battery is used as a power source has been described. However, any type of battery can be applied as long as it has a generally flat surface. Further, the speaker 26 is bonded to the outer surface of the ring and the position facing the audio signal receiving unit on the ring, that is, the palm side when worn, and the output of the speaker drive circuit 22 is connected to the input terminal of the speaker 26 The output of the infrared light receiving device 21 is connected to the input of the speaker drive circuit 22. The infrared light is modulated by an audio signal. The infrared signal is received by the infrared light receiving unit 27 installed in the infrared light receiving device 21, and the received signal is demodulated by the infrared light receiving device 21. After that, the speaker 26 is driven to reproduce an audio signal.

  When using this device, if the above-mentioned ring is put on a finger, the speaker 26 is positioned on the palm side, so that the speaker 26 can be brought to the position of the ear so as to cover the ear with the hand. As described above, the speaker 26 can be positioned near the outer ear without inserting the sounding body into the ear canal, and the environmental sound can be blocked only by use by hand, so that a clear received sound can be obtained. It has the following characteristics. In addition, the ring is one of the things that are always worn and worn, so it does not give a sense of incongruity even when worn at all times, and it does not block the ears except when in use, thus delaying danger avoidance due to the inability to hear environmental sounds. In addition, there is also a feature that does not have a defect that causes trouble in daily life, such as being unable to specify the position of the sound source.
