DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an earphone microphone, and more particularly, to a microphone including a vibration sensor.

[0002]

2. Description of the Related Art In recent years, the development of electronic devices has been remarkable, and functions have been diversified. In particular, portable electronic devices, mainly portable telephones, have been moving toward more user-friendly functions, starting from their portability. Under such circumstances, various advances have been made in microphones constituting a part of electronic devices. FIG. 3 (part structure diagram) and FIG. 4 (use state diagram)
There is an earphone microphone shown in. As shown in FIG. 3, the microphone includes an earphone unit 31, a microphone unit 32, a jack unit 33, and a cable 34.
Consists of In this configuration, the earphone section 31 is inserted into the ear canal to listen to the voice, and the microphone section 32 is positioned at the mouth to transmit the voice information. When speaking,
Since it is necessary to clearly utter the voice so that the microphone can recognize the voice, it is not suitable for use in a case where it is desired to eliminate the influence of noise in a loud noise or where a quiet voice is desired to be spoken.

[0003] Japanese Patent Application Laid-Open No. 153490 discloses a microphone in which a microphone portion is placed on the mandible and the sound is sensed from the vibration of the bone during vocalization. In general, a microphone senses sound by directly transmitting sound as air vibration, but the microphone disclosed in the above publication has a structure in which sound is sensed not by air vibration but by bone vibration. ing. Therefore, there is a feature that a voice can be sensed even in a place where the noise is severe, while eliminating the influence of the noise.

Japanese Utility Model Laid-Open Publication No. Sho 36601 discloses a laryngeal stroboscope which is not used for telephones but mainly used for medical treatment and the like. This laryngeal stroboscope has a structure in which an audio signal is sensed as a vibration of the audio near the larynx or the mouth. In this voice sensing method, the device is directly attached to the larynx, that is, a part of the trachea, or the device is used by positioning the device near the mouth. Japanese Patent Laying-Open No. 120159/1990 discloses a mobile phone device in which a handset section is separated from a main body as headphones, and the headphones are provided with an earphone and a microphone. With this structure, the device can be used while the mobile phone device is kept in a bag or the like.

[0005] Japanese Patent Application Laid-Open No. 56682 discloses an earphone microphone provided with two microphones. One of the two microphones is a normal microphone and the other microphone is a bone conduction microphone. Since the sound signal is sensed by the vibration of the skull or the like when it is worn on the ear, the sound can be transmitted clearly even in a place with a lot of noise or in a quiet place.

[0006]

In JP-A-153490 and JP-A-56682, sound is sensed not by air vibration but by bone vibration (although the bone part is different). Such a voice sensing method is effective when it is desired to eliminate the influence of noise in a place where the noise is intense, or when it is necessary to make a small utterance in a quiet place. However, there is a limit to accurate sensing in the case of sensing by bone vibration, and there is a problem particularly in sensing a small sound. For example, it is difficult to use when uttering with a small voice in crowds such as trains. 36601
The voice sensing method disclosed in Japanese Patent Application Laid-Open Publication No. H10-157, as long as it is used temporarily for medical use, is not suitable as a method generally used in electronic devices such as portable electronic devices.

[0007]

In order to solve the above-mentioned problems, the present invention is configured such that an arm portion composed of a semi-circular elastic body connecting two microphones is wound from the front to the back of the neck. An earphone microphone that senses vibration of the vocal cords at the time of vocalization and transmits voice information by providing two microphones near a vocal cord portion of the neck where voices are actually produced. By using the electronic device including the microphone according to the present invention, even in crowded places such as trains and places where noise is intense, it is possible to accurately sense small voices and perform conversation. In addition, it is possible to more accurately detect a small voice as compared with a method of detecting a vibration of a bone in a portion apart from a vocal cord where a voice is actually emitted.
