Abstract

(57) [Summary] [Problem] To provide a microphone having good reception quality without external sound. SOLUTION: A joint 12 is provided at one end of a main body 1, and a receiver 2 of an audio source is provided on the joint. The audio source receiver 2 is fastened and fixed to a portion where the audio source is input. Moreover, the receiver 2 of the audio source is affixed so as to be adjusted by the main body 1 so as to match the part of the audio source. Thereby, the sound wave coming out of the audio source is transmitted to the audio source output device via the signal line 50 and the signal line 52 connected to the receiver of the audio source, and outputs the audio. Since the sound source output device receives only sound waves coming out of the sound source part, and other sounds from the outside world cannot enter the sound source receiver, the microphone can send clear sound and eliminate other noise. It becomes possible.

[Detailed description of the invention]

[0001]

[Technical field to which the invention belongs]

 The present invention relates to a microphone, and more particularly to a piezoelectric microphone.

[0002]

[Prior art]

 The conventional skin-contacting microphone has a main body, and a receiver for an audio source is provided at one end of the main body. The receiver of the audio source is connected to one end of the signal line. Further, a plug is arranged at the other end of the signal line. The microphone is fastened to the audio source via the body of the microphone. Moreover, the receiver of the audio source is attached near the location of the audio source. The sound wave coming out of the sound source is converted into a signal by the receiver of the sound source, and the signal is input to the sound source output device via the signal line. The audio source output device converts the signal to audio and outputs it.

[0003]

[Problems to be solved by the invention]

 However, since the conventional microphone is not attached so as to be in close contact with the sound source part, the sound wave transmitted from the sound source part cannot be completely output from the sound source output device, and human beings cannot output sound. Difficult to identify.

In the case of a portable telephone, an earphone is provided at one end of a first signal line and a receiver is provided at one end of a second signal line in a handset not held by hand. At the other end of the two signal lines is a plug. Insert the plug into the mobile phone jack. Therefore, the mobile phone signal is transmitted to the earphone via the first signal line. The earphone converts the signal to sound and outputs it. On the other hand, the user's voice is converted into a signal by the receiver, and the signal is output to the mobile phone via the second signal line.

However, in addition to the user outputting voice to the mobile phone via the receiver and the second signal line, external voice is also transmitted to the mobile phone via the receiver and the second signal line. It is. As a result, the receiving party not only hears the user's voice, but also hears the external voice, and the quality of the received voice deteriorates, and the voice of the user's dispatch cannot be clearly heard. Therefore, a main object of the present invention is to provide a piezoelectric microphone that comes into contact with the skin.

[0006]

[Means for Solving the Problems]

 In order to achieve the above object, a piezoelectric microphone according to the present invention is provided with a main body at the center. At one end of the main body, a receiver for a sound source is provided. The receiver of the audio source is fastened to the part of the audio source via the main body. Moreover, the receiver of the audio source is attached to the part of the audio source. Thereby, when a sound wave of the sound source comes out, the sound wave is transmitted to the sound source output device via the signal line connected to the receiver of the sound source, and the sound is output. Since the audio source output device receives only sound waves coming out of the audio source site, and no other audio from the outside world enters the audio source receiver, the microphone transmits clear audio and has no other noise.

[Embodiment of the invention]

 Hereinafter, embodiments of the present invention will be described with reference to the drawings.

As shown in FIG. 1, the piezoelectric microphone of the present invention is provided with a main body 1. At one end of the main body 1 is a receiver 2 of an audio source. The audio source receiver 2 is connected to the first signal line 50. The plug 3 is arranged at the other end of the first signal line 50 corresponding to the receiver of the audio source. The microphone is fastened to the part of the audio source via the main body 1. (In the embodiment of the present invention, the part of the audio source is throat, but it is not limited in actual application.) The receiver 2 of the audio source is attached to the part of the audio source. Thereby, the sound wave from the audio source is converted into a signal by the receiver 2 of the audio source, and is input to the first signal line 50. A signal is input to the audio source output device connected to the plug 3 via the first signal line 50. (In an embodiment of the present invention, the audio source output device is a speaker or a mobile phone, but in an actual application, it is not limited.) The audio source output device converts the signal into audio and outputs it.

As shown in FIGS. 1 and 3, the main body 1 is formed of a fixed portion and an active portion installed on the fixed portion. In order to adjust the dimensions of the body 1, the active part can be extended from the fixed part or retractable to the fixed part.

[0010] At one end of the main body 1, a receiver 2 of an audio source is pivotally mounted so as to be active. A first shell 21 is provided at one end corresponding to the joint 12 in the receiver 2 of the audio source. On the inner peripheral edge of the first shell 21, a first locking unit 212 is arranged near the upper end. The receiver 2 of the audio source has a second shell 28 at the other end corresponding to the joined body 12. A plurality of conical through holes 282 are provided on the surface of the second shell 28. In the second shell 28, a second locking unit 284 is arranged at one end corresponding to the first shell 21. By locking the second locking unit 284 and the first locking unit 212, the first shell 21 and the second shell 28 are joined.

As shown in FIGS. 2 and 3, a piezoelectric buzzer 6 and a circuit board 64 are provided between the first shell 21 and the second shell 28. The piezoelectric buzzer 6 is connected to a circuit board 64 by a wire 66. The piezoelectric buzzer 6 includes a first metal piece 622 and a second metal piece 624 attached to a predetermined position near the center of the first metal piece 622. The circuit board 64 is provided with a buffer 23 at the other end corresponding to the piezoelectric buzzer 6. (The cushion of the embodiment of the present invention is foamed cotton, but it is not limited in actual application.) The sound wave passes through the through hole 282 and is received by the two metal foils 622 and 624. The circuit board 64 converts the sound wave into a signal via the wire 66 and outputs the sound, and at the same time, the transmission of the sound wave is buffered by the buffer, so that the sound wave is not transmitted to the two shells 21 and 28.

The circuit board 64 is connected to one end of the first signal line 50. The end of the first signal line 50 passes through a predetermined position of the first shell 21 and is exposed to the outside of the first shell 21. At the other end, a plug 3 is provided. Insert the plug 3 into the audio source output device. When a signal is input to the circuit source 64 to the audio source output device via the first signal line 50, the audio source output device converts the signal into audio and outputs it.

As an embodiment of the present invention, as shown in FIG. 1, the plug 3 has a second signal line 52. The earphone 4 is arranged at the other end of the second signal line 52 corresponding to the plug 3. The output signal of the audio source output device is sent to the earphone 4 via the second signal line 52. The earphone 4 converts the signal into sound and outputs the sound.

As an embodiment of the present invention, as shown in FIG. 1, a joint body 12 is provided at one end of each of the main bodies of the hoops. A through hole (note: not shown) is provided at a position near the center of the joined body 12. A universal joint is arranged at the end of the first shell 21 and can be connected to the through hole. By rotating the universal joint in the through-hole, the angle of the audio source receiver 2 can be adjusted.

When the plug 3 is inserted into an audio source output device (for example, a mobile phone) by means of the above elements, the microphone is connected via the main body 1 to a part of the audio source (for example, a user's neck). Can be left in place. By adjusting the angle of the audio source receiver 2 while rotating the universal joint 26, the audio source receiver 2 is attached to the audio source part in close contact. In this manner, when a sound wave comes out, the sound source transmits the sound to the sound source output device via the first signal line 50 connected to the receiver 2 of the sound source, and outputs the sound. At the same time, the output signal of the audio source output device is output to the earphone 4 via the second signal line 52. Since the sound waves of other sounds in the outside world do not contact the receiver 2 of the sound source, the other sound sources in the outside world can output sound via the receiver 2 of the sound source and the first signal line 50. Can not. That is, since the sound source receiver 2 receives only the sound wave coming out of the sound source part, the microphone transmits a clear sound and there is no other noise.

However, what has been described above is only one of ideal examples for explaining the present invention, and the present invention is not limited in any form. Therefore, any improvement or modification made by a person skilled in the art with the same spirit of the invention is included in the protection scope of the invention.
