Abstract
The utility model discloses a mobile phone with a voice amplifying circuit, which is further provided with an audio amplifying circuit. The input end of the audio amplifying circuit is connected with two ends of a mobile phone pickup through voice signal lines, the output end of the audio amplifying circuit is connected with a loudspeaker, a power supply input end of the audio amplifying circuit is connected with a mobile phone power supply, and a control switch is arranged between the pickup and the audio amplifying circuit. The audio amplifying circuit and the control switch form the voice amplifying circuit together, the audio amplifying circuit and a control circuit are integrally arranged on a small-piece circuit board, and six flat cables are led out from the circuit board and respectively connected with the loudspeaker, the power supply and the pickup. The voice amplifying circuit is arranged in the mobile phone and connected or disconnected by the control switch, thereby being simple in structure and convenient and practical. The mobile phone with the voice amplifying circuit can be used as a microphone which is carried with users for vocal accompaniment and karaoke, and further can be used as a temporary loudspeaker for teachers in class, conference presentation and other occasions.
Description
Technical field
The utility model relates to the mobile communication product technical field, is specifically related to a kind of mobile phone that has audio-amplifying circuit.
Background technology
Improving constantly of Along with people's living standard, the popularity of mobile phone is also increasingly high, even has many people to reach several of a people's degree.Present cell-phone function is more and more; Except traditional conversation, receive and send messages etc.; Music video broadcast, photograph video etc. have also been increased; Wherein music (being the MP3 function) is to use one of function the most widely, has spent many boring times by the MP3 playing function people of mobile phone.Yet at present on the market mobile phone is of a great variety, but all lacks the very practical function of one item missing, i.e. loudspeaker and music accompany function, and this makes people can not use the mobile phone exercise to sing, and has limited the function of mobile phone, has brought some to regret for people's use.
The utility model content
The technical problem that the utility model will solve provides a kind of simple in structure, the mobile phone that has audio-amplifying circuit that can sing in order to exercise.
For solving the problems of the technologies described above; The utility model adopts following technical scheme: a kind of mobile phone that has audio-amplifying circuit, comprise mobile phone body, and mobile phone body is provided with screen, button, loudspeaker, battery and circuit board; The mobile phone governor circuit is arranged on the circuit board; It is characterized in that: this mobile phone also is provided with audio amplifier circuit, and the audio amplifier circuit input is connected with mobile phone pick-up two ends through the voice signal line, and the output of audio amplifier circuit connects loudspeaker; The power input of audio amplifier circuit connects cellular phone power supplies, between pick-up and audio amplifier circuit, is provided with control switch; Audio amplifier circuit constitutes audio-amplifying circuit with control switch.
Further; Said audio amplifier circuit and control circuit are done as a whole being arranged on the dice-circuitry plate, pick out six roots of sensation winding displacement from this circuit board, and six roots of sensation winding displacement is connected with loudspeaker, power supply and pick-up respectively; Be specially; 1,2 lines are connected with loudspeaker, and 3,4 lines are connected with power supply, and 5,6 lines are connected with pick-up.
Further, described dice-circuitry plate is installed in mobile phone inside, and control switch exposes the side in mobile phone body.
When getting into music playing mode; Sound is from loudspeaker; Because the music audio signal of mobile phone is imported loudspeaker with the signal that obtains from pick-up as two separate signal, the exportable mixed signal by music player and this device and audio-amplifying circuit input of loudspeaker this moment is to reach the purpose of music accompany; Can open the music accompany function through control switch, audio-amplifying circuit plays micropkonic function; When mobile phone is in off-mode or does not have incoming call, open audio-amplifying circuit and get final product operate as normal; When incoming call, close audio-amplifying circuit and get final product, mobile phone communication is had no influence.
The utility model is through being provided with audio-amplifying circuit in mobile phone, and opens or close with control switch, and it is simple in structure, and is convenient and practical, and mobile phone is practised singing in order to vocal accompaniment as the loudspeaker that people carry; Also can be used for occasions such as the teacher gives a lesson, meeting speech in addition uses as interim megaphone.
