ていた。2. Description of the Related Art Such a bone conduction sound detecting device is capable of transmitting a so-called bone conduction sound transmitted as mechanical vibration from a vocal cord to an ear by bone conduction into a concha region of a concha, in a state of being brought into contact therewith. Is converted into an electric signal by a piezoelectric element housed in the device and detected. With a general microphone such as an electret condenser type, there are many cases where the external noise is detected and the user's voice cannot be accurately detected, but by detecting the bone conduction voice as described above, the influence of the external noise is suppressed. Thus, the voice of the user can be accurately detected. In the form of detecting bone conduction sound in the human ear, it is necessary to accurately contact the housing containing the piezoelectric element into the concha of the concha in order to detect bone conduction sound efficiently. A configuration has been considered in which the housing is formed in a shape similar to the shape of a so-called earphone housing and is brought into contact with the concha of the concha.

的に検出できるようにする点にある。However, in the above-mentioned conventional configuration, since the shape and size of the concha region of the ear differ from person to person, the user changes the posture by tilting the head or the like. Occasionally, the contact state of the housing with the concha cavity becomes unstable, the detection efficiency changes, and the detected voice signal amount fluctuates, thereby lowering the detection quality. The present invention has been made in view of the above circumstances, and its purpose is to more efficiently and stably transmit bone conduction sounds regardless of the shape and size of the concha region of the ear to be worn. The point is that it can be detected.

検出できるものとなった。According to the first aspect of the present invention, when the bone conduction sound detecting device is mounted on the ear, the housing and the ear can be elastically deformed. The housing for accommodating the piezoelectric element is attached to the concha of the concha such that it is located between the ear cavities.
Due to this, the housing is pressed to the side in contact with the concha area due to the elastic return force of the elastically deformed mounting auxiliary member, and even if the shape and size of the concha area to be mounted are different. In addition, an appropriate contact force can be obtained in a stable state. Thus, bone conduction sound can be detected more efficiently and stably regardless of the shape and size of the concha region of the ear.

The detected housing is attached so that the detection unit housing comes into contact with the concha of the concha so that the bone conduction voice of the user can be detected and the voice signal transmitted by the user can be heard. Therefore, it is preferable to use it as a voice input / output device for a communication device such as a telephone device and a wireless device.

ことで、装置構成の簡素化を図れる。[0006] When the piezoelectric element and the earphone for reception are provided in this manner, the vibration of the earphone for reception accompanied by the sound emission may be detected by the piezoelectric element. By supporting the unit housing and the earphone housing accommodating the earphone for reception in a forked shape, it is possible to suppress transmission of vibration from the earphone for reception to the piezoelectric element. Further, as described above, when the detection unit housing and the earphone housing are bifurcated, the degree of freedom of attachment of the mounting auxiliary member is greater in the earphone housing than in the detection unit housing that comes into contact with the concha region. Since the mounting auxiliary member is provided on the outer periphery of the earphone housing, the configuration of the device can be simplified.

It is mounted in a state where the portion is sandwiched, and the mounting auxiliary member is detachable. Therefore, while the mounting auxiliary member has elasticity for pressing the housing, the mounting auxiliary member is also attached to the housing to simplify the configuration, and some users do not need the mounting auxiliary member. In some cases, the bone conduction sound detecting device can be made more convenient because the attachment assisting member can be appropriately removed.

着することができる。The contact force of the detection unit housing 2 with respect to the bottom 52A of the concha cavity 52 depends on the weight of the earphone unit ER and the bone conduction audio pickup unit BP and the holding member 2
With only the one obtained by the action of 0 or the like, it may become unstable depending on the shape and size of the user's ear 50, but as described above, it is accurately determined by the elastic return force of the mounting auxiliary member 15. To the concha cavity 52
By pressing against the bottom 52A, even if the user changes the posture by tilting the head or the like, the contact force does not fluctuate much,
The state where the piezoelectric element 6 accurately detects the bone conduction sound can be stably maintained without being affected by the body hair of the skin or the like. If a stable contact force can be obtained without the mounting auxiliary member 15, the mounting auxiliary member 15 can be removed and mounted as described above.

The vibration reaching the surface of the concha region 52 is transmitted to the piezoelectric element 6 in the detection unit housing 2 and converted into an electric signal. After being processed by the signal processing board 7, the electric signal is transmitted to the other party of the call via the input / output cable 5. On the other hand, when the communication device receives the voice signal emitted by the other party of the call, the voice signal is input to the earphone 10 for receiving via the input / output cable 5, and the earphone 10 for receiving
The other party's voice is emitted toward the ear canal 51.

The receiving earphone 10 is provided to enable not only the detection of the bone conduction sound but also the listening of the audio signal. However, the detection of the bone conduction sound is performed only by the piezoelectric element 6 without the receiving earphone 10. You may do it. In the above-described embodiment, the case where the detection unit housing 2 is pressed against the bottom portion 52A of the concha cavity portion 52 to make contact therewith is exemplified. For example, the position at which the housing 1 is brought into contact for the detection of the bone conduction sound can be appropriately changed as long as the position is within the concha of the concha.
