Description

[Detailed description of the invention]

[0001]

[Technical field to which the invention belongs]

 The present invention relates to a kind of hands-free device of a mobile phone, and more particularly, to a hands-free device of a mobile phone that can selectively switch between reception of vibration sound waves and direct sound reception.

[0002]

[Prior art]

 One of the drawbacks of microphones for mobile phones that are currently in common use is that they employ a direct sound pickup method, namely, when the user is in a noisy place, external noise emitted from sources other than the user himself. This makes it easier for the listener to listen to the message, which in turn affects the quality of the transmission. In order to solve such a problem, a skin contact type piezoelectric microphone as shown in FIG. 1 has already been provided, and the microphone is brought into contact with the front edge of the lower case and the position of the user's throat. The sound wave vibration generated when speaking in the throat is transmitted through the spring to the circuit device. The spring used in the hands-free device of such a dual-effect type mobile phone is liable to be subjected to elastic fatigue due to vibration, thereby affecting reception quality. Also, the sound quality obtained by using sound wave vibrations may cause the listener to feel uncomfortable with the actual voice, and a single-function microphone is often used in only a single place, and Therefore, the sound pickup quality could not be selected, and the user could not immediately know that there was a call on the mobile phone, such as when going out in the crowd or riding a motorcycle.

[0003]

[Problems to be solved by the invention]

 As can be seen from the above, the range and location of mobile phones and the external noise limit the microphones of existing mobile phones. Therefore, the main issue of the present invention is to design the microphone of the mobile phone so that the user can be notified immediately when the mobile phone is called.

[0004]

Means for Solving the Problems According to the invention of claim 1, there is provided a microphone body, a fixed band, and an earphone, and a control switch provided at one end of the fixed band is provided within a case above and below the microphone body below the fixed body. A transmitting means and a receiving means are provided inside the upper case of the microphone body and connected to the circuit device, and the receiving means and the transmitting means mounted in the mobile phone mutually receive and transmit, and the upper case surface of the microphone body is formed. The light source of the light emitting means is installed in a ring inside the transparent cover of the light emitting means to instruct the user to call the mobile phone, and the microphone body is attached to the throat neck with a fixed band. The transmission is received after being attached, and the two circuit devices in the microphone body are switched by switching the control switch to receive the vibration sound wave or directly. Characterized in that it receives a voice, and a mobile phone hands-free device. The invention according to claim 2 is characterized in that one end of the fixed band and the microphone body are connected to a vibrating device, and the connecting device receives a call signal transmitted from the vibrating device in the mobile phone and is attached to the throat neck. 2. The hands-free device for a mobile phone according to claim 1, wherein a notification is made through the main body so that a quick call can be received. The invention according to claim 3 is characterized in that the transparent cover has a replaceable form, and a different appearance is obtained by replacing a case as necessary.
