Abstract

(57) [Summary] An object of the present invention is to provide a function switching device for a mobile phone. SOLUTION: Since a search circuit 1 is for detecting a signal of a mobile phone by connecting to a mobile phone, when a signal of the mobile phone is received, a command for switching to a format of the mobile phone is transmitted to the switching circuit 2. You can talk. Conversely, when the mobile phone is cut off, the detection circuit 1 cannot measure the signal of the mobile phone.
To send a command to switch to the radio format. When the connection terminal 6 is separately connected to a sound reproducing device, music can be enjoyed.

[Technical field to which the invention belongs]

 The present invention relates to a function switching device for a mobile phone.

[0002]

[Prior art]

 In recent years, with the advancement of wireless communication technology and the spread of wireless communication equipment, it has become possible to make calls anywhere.

[0003] A diplomat who frequently goes out needs to rely on the convenience of a mobile phone, and talking while driving is apt to cause a traffic accident. . If you put a microphone on your chest, you can make a call by pressing the call button on your mobile phone even if you receive a call while driving. By doing so, if the number of ring tones exceeds the set number when a call is received, a call is automatically established. As a result, it is no longer necessary to drive while holding a mobile phone with one hand, and traffic accidents caused by the phone while driving are reduced.

[0004]

[Problems to be solved by the invention]

 While many young people have mobile phones, students and new members of society prefer new and varied ones, so that well-known earphones and mobile phones with microphones have no functions other than calling. There is a demand for a product in which a new function is added to a mobile phone. In view of such demands, the present invention aims to provide a function switching device for a mobile phone. Another object of the present invention is to provide a function switching device for a mobile phone that automatically switches between a mobile phone function and a radio function by detecting a signal of the mobile phone for a consumer with an effect having novelty. It is in.

[0005]

Means for Solving the Problems A function switching device for a mobile phone according to the present invention for achieving the above object is formed by a search circuit, a switching circuit, a radio, an earphone, a microphone, and a connection terminal. . Since the detection circuit is used to detect the signal of the mobile phone by connecting to the mobile phone, it is possible to talk by receiving the signal of the mobile phone and transmitting to the switching circuit a command to switch the type of the mobile phone. It is. Conversely, if the mobile phone disconnects and the probing circuit cannot measure the signal of the mobile phone, it transmits a command to switch to the radio format to the switching circuit. If the connection terminal is separately connected to a sound reproducing device, music can be enjoyed. From these facts, according to the function switching device of the mobile phone of the present invention, consumers can be attracted by realizing new functions in the mobile phone.

[Embodiment of the invention]

Hereinafter, embodiments of the present invention will be described with reference to the drawings. As shown in FIG. 1, one embodiment of the present invention is formed by a detection circuit 1, a switching circuit 2, a radio circuit 3, an earphone 4, a microphone 5, and a connection terminal 6.

The search circuit 1 can detect a signal of a mobile phone by connecting to a mobile phone (not shown). The switching circuit 2 is connected to the detection circuit 1 and can switch between a radio function and a mobile phone function under the control of the detection circuit 1. The radio circuit 3 can receive a signal from a broadcasting station by connecting to the switching circuit 2. The earphone 4 can transmit a message by a radio circuit or a mobile phone circuit by being connected to the radio circuit 3. The microphone 5 is capable of transmitting a message to a mobile phone when the mobile phone is connected to the mobile phone directly and when the type is switched to the mobile phone. The connection terminal 6 can be separately connected to a sound reproducing device.

With the above-described structure, if the mobile phone is connected to the cord connecting the detection circuit 1 and the microphone 5 and the radio circuit 3 is turned on, the program of the broadcasting station can be heard. Also, when an incoming signal arrives at the mobile phone, the search circuit 1 detects the signal of the mobile phone and transmits a command to the switching circuit 2 to switch to the function of the mobile phone, thereby enabling a telephone conversation. When the call is completed and no signal from the mobile phone is received, when the search circuit 1 transmits a command to switch to the function of the radio circuit to the switching circuit 2, the radio circuit 3 can be continuously heard. Therefore, the search circuit 1 can identify the incoming signal of the mobile phone. That is, the switching circuit 2 can switch the operating radio circuit 3 to the mobile phone, or can switch to the radio circuit 3 when the call is completed.

[0009] From the above, it is possible to automatically switch from a radio format to a mobile phone format, and to automatically switch between a mobile phone function and a radio function. Novelty can attract consumers' interest. The connection terminal 6 can enjoy other music even if a small-sized sound reproducing device, for example, a portable cassette player, a portable CD player, an MP3 player, or the like is separately connected, and receives a mobile phone incoming signal. Then, since the format can be switched to the format of the mobile phone, the above-mentioned effect is achieved.
