[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention comprises a main unit for communicating with another telephone device, and a talker having a microphone and a speaker for transmitting and receiving a voice signal to and from the main unit. The main unit is provided with a main unit-side wireless communication device for wirelessly communicating with the talker, and the telephone unit is provided with a talker-side wireless communication device for communicating with the main unit wireless communication device. Telephone equipment.

[0002]

2. Description of the Related Art In such a telephone apparatus, a main body section for communicating with another telephone apparatus is provided with a main body side radio communication apparatus for wirelessly communicating with a telephone having a microphone and a speaker. The talker is provided with a talker-side wireless communication device for communicating with the main unit wireless communication device.
That is, the main unit corresponds to a base unit of a so-called cordless telephone, and the telephone unit corresponds to a child unit. With the telephone device having such a configuration, a user of the telephone device can use the telephone unit. By use, the use position is not so much restricted, and it is convenient. By the way, conventionally, as a microphone provided in a telephone, a so-called air-conducting microphone that picks up a sound emitted from a user's mouth and propagated in the air is generally used.

[0003]

Therefore, in the above-mentioned conventional configuration, the speaker and the air-conducting microphone are connected to the CCITT.
The ergonomic position determined by the EIA or the EIA, that is, the speaker must be placed near the user's ear and the air-conducting microphone must be placed near the user's mouth, which increases the size of the talker. There was an inconvenience. In addition, the air-conducting microphone detects not only the voice uttered by the user but also the surrounding noise, etc., which becomes noise and degrades the quality of the transmitted voice, making it difficult for the other party to hear the call. There were also inconveniences. The present invention has been made in view of the above circumstances, and an object of the present invention is to improve the communication quality as much as possible and to reduce the size of the telephone.

[0004]

According to the first aspect of the present invention, the microphone provided in the telephone is mounted in the concha of the human ear so as to be in contact therewith, and the vocal cords are provided. The apparatus is provided with a voice vibration detection device that detects voice vibration from the vocal cords, and detects a so-called bone conduction voice transmitted from the vocal cords to the ear by bone conduction. Therefore, it is not necessary to dispose the microphone near the mouth of the user, and it is possible to dispose the microphone and the speaker close to each other, so that the size of the talker can be reduced. In addition, since the microphone of the telephone detects the bone-conducted voice, the detection of ambient noise is sufficiently suppressed. As a result, it has become possible to provide a telephone device capable of improving the communication quality as much as possible and reducing the size of the telephone.

[0005] Further, with the configuration of the second aspect, when the telephone is used, the housing of the voice vibration detecting device and the housing of the speaker, which are integrally formed, are used by being attached to the ears. In this state, the piezoelectric element provided in the housing of the voice vibration detection device converts the voice vibration propagated from the vocal cords to the ears by bone conduction to an electric signal, which is transmitted to the other party of the call and the other party of the call. The sound is emitted from an earphone-type speaker to the ear canal. Therefore, since the voice vibration detecting device of the telephone and the speaker are integrally mounted on the ear, the handling is easy for the user, and the telephone can be further downsized.

Further, with the above configuration, when the user operates a call command switch of the talker when the main body receives a call signal from the other party of the call, the main body side wireless communication is performed. Transmission and reception of an audio signal for communication with the other party are started between the communication device and the wireless communication device on the telephone side. Therefore, taking advantage of the small size of the handset as described above, if the user carries the handset, the user will be away from the main body when a call is received from the other party of the call. Even if it is located, it is possible to use the telephone in such a manner that the telephone is immediately started by operating the telephone command switch of the telephone, thereby making the telephone device more convenient.

[0007] Further, by providing the configuration of the fourth aspect, the telephone has a holding member for holding the edge of the concha cavity together with the housing of the voice vibration detecting device.
In a state in which the edge of the concha cavity is held between the housing and the holding member and the ear is attached to the ear, the talker-side wireless communication device is connected to a signal line hanging downward from the housing of the voice vibration detection device. The housing for the telephone to be stored is suspended and supported. Therefore, by holding the edge of the concha cavity by the housing and the holding member of the voice vibration detection device, the state of being attached to the ear of the talker is maintained, whereby the user of the telephone device can handle the talker. There is no need to hold it by hand, so that other operations are not hindered even when the telephone device is used, and the telephone device can be made more convenient. In addition, the housing for the talker has an appropriate weight, so that the contact between the housing of the voice vibration detection device and the concha region can be more reliably achieved.

Further, by providing the configuration according to the fifth aspect, the main body side wireless communication device includes a transmitting / receiving unit separate from the main body housing for housing the main body, and a transmitter / receiver unit inside the main body housing. And a communication control unit to be housed therein. The communication line of the transmission / reception unit is connected to an audio signal input / output terminal provided in the housing for the main body, whereby the two are connected. Therefore, even when the main body does not have a transmitting / receiving antenna or a transmitting / receiving circuit for wireless communication with the telephone, the transmitting / receiving antenna or the transmitting / receiving circuit is provided at the audio signal input / output terminal generally provided in the main body. Connect the transmitting / receiving unit,
By incorporating the function of the communication control unit for communication using the transmission / reception unit into the control device originally provided in the main unit as necessary, wireless communication between the main unit and A conventional telephone device without a wireless communication function with a device can be effectively used as it is or with a slight modification.

[0009] Further, by providing the structure of the above-mentioned claim 6, the main body is constituted by a portable radio telephone device. Portable wireless telephone devices are generally small enough to be carried by the user at all times and can be used by the user at any time.However, they still require a certain amount of size, and can be used while carrying luggage. Although it is inconvenient, if the telephone can be communicated using the miniaturized telephone as described above, the handling of the telephone device becomes extremely easy. Furthermore, a portable wireless telephone device requires a certain size, and is often carried in a bag or the like, rather than in a user's clothes. When the user operates the talk command switch of the talker when a call signal is received from the other party of the call, the call between the wireless communication device on the main unit and the wireless communication device on the talker side becomes a call with the other party. When the transmission / reception of the audio signal is started, it is possible to make a telephone call without taking the main body part out of a bag or the like, which can be used more conveniently.

[0010] With the above configuration, the transmission / reception antenna and the transmission / reception circuit forming part of the main body side radio communication apparatus are housed in a transmission / reception unit separate from the main body housing. Even in the case of this type, since the housing for the main body and the storage case for storing the transmission / reception unit are provided, the main body composed of the portable wireless telephone device can be easily carried. In addition, by providing the configuration according to claim 8, the storage case further includes:
Since the telephone unit is provided with a telephone storage unit for storing the telephone, it is easy to carry the entire telephone device, and the location of the downsized telephone is clarified to prevent the telephone from being lost.

[0011] With the above configuration, the main body is constituted by a stationary telephone device. In general, the main body of such a telephone device is often arranged at an office desk or the like, but in such a case, the size of the telephone is small and the degree of freedom of the position of the user is large as described above. Therefore, it is easy to continue work even when a call is received, and it is also possible to make a call while taking a posture that makes it easy to refer to materials and the like, and it is extremely effective to reduce the size of the talker as described above. .
