Embodiment
In order to make the object of the invention, technical scheme and advantage clearer,, the present invention is further elaborated below in conjunction with accompanying drawing and embodiment.Should be appreciated that specific embodiment described herein only in order to explanation the present invention, and be not used in qualification the present invention.
Handset audio of the present invention is put devices and methods therefor outward and is transferred to built-in loudspeaker or audio frequency transmitting element through the voice signal with mobile phone output; External voice box receives voice signal and the sounding that the audio frequency transmitting element sends; Thereby making the audio frequency of mobile phone put outward can to satisfy many people listens to, and the volume of sounding is bigger.
Please refer to Fig. 1 and Fig. 2, the handset audio that the embodiment of the invention provides is put device outward and is comprised mobile phone 100 and external voice box 200.
The voice signal that commutation circuit 120 is exported baseband chip 110 according to the control signal of baseband chip 110 transfers to built-in loudspeaker 130 or audio frequency transmitting element 140.
Audio frequency receiving element 210 receives the voice signal that audio frequency transmitting element 140 sends, and through audio output unit 220 sounding.
Handset audio of the present invention is put device outward and through commutation circuit 120 voice signal of baseband chip 110 output is transferred to built-in loudspeaker 130 or audio frequency transmitting element 140; The audio frequency receiving element 210 of external voice box 200 receives the voice signal that audio frequency transmitting element 140 sends; And through audio output unit 220 sounding; Thereby making the audio frequency of mobile phone put outward can to satisfy many people listens to, and the volume of sounding is bigger.
Further, baseband chip 110 comprises controller 111 and audio processing modules 112.Audio processing modules 112 is used for the voice analog signal that mobile phone 100 receives is amplified, and the voice digital signal of perhaps mobile phone 100 being stored converts voice analog signal into and amplifies.Controller 111 is used to transmit control signal to commutation circuit 120.
Further, above-mentioned mobile phone 100 also comprises external voice box detecting unit 150.External voice box detecting unit 150 all links to each other with audio frequency transmitting element 140 and baseband chip 110.External voice box detecting unit 150 is used to detect audio frequency transmitting element 140 and whether is connected with load, and promptly the audio frequency receiving element 210, and sends the relevant detection consequential signal and give baseband chip 110.If audio frequency receiving element 210 has with audio frequency transmitting element 140 and is connected, 110 control of baseband chip commutation circuit 120 transfers to audio frequency transmitting element 140 with voice signal, otherwise control commutation circuit 120 transfers to built-in loudspeaker 130 with voice signal.
Further, audio output unit 220 is loudspeaker.
Further, audio frequency transmitting element 140 is an audio frequency I/O interface, and audio frequency receiving element 210 is an audio jack.During use, audio jack is inserted audio frequency I/O interface, thereby voice signal is transferred to audio output unit 220.
Further, audio frequency transmitting element 140 is an ANTENNAUDIO transmitting element, like bluetooth, infrared or FM transmitter.Correspondingly, audio frequency receiving element 210 is an ANTENNAUDIO receiving element, like bluetooth, infrared or FM receiver.During use, the ANTENNAUDIO transmitting element converts voice signal into wireless signal; The ANTENNAUDIO receiving element is reduced to voice signal with wireless signal after receiving wireless signal.
Please refer to Fig. 3, the handset audio that the embodiment of the invention the provides method of putting outward may further comprise the steps:
Step S1: start the speech play program, like integrated music player of mobile phone and broadcast receiver etc.
Step S2: time-delay a period of time, voice signal is carried out processing such as filtering, to reduce noise.
Step S3: amplify voice signal.
Step S4: whether detection of handset 100 links to each other with external voice box 200.Be then to get into step S5, otherwise get into step S6.
Step S5: the voice signal of mobile phone 100 outputs is transferred to external voice box 200.
Step S6: the built-in loudspeaker 130 that the voice signal of mobile phone 100 outputs transferred to mobile phone.
Handset audio of the present invention is put devices and methods therefor outward and through commutation circuit 120 voice signal of baseband chip 110 output is transferred to built-in loudspeaker 130 or audio frequency transmitting element 140; The audio frequency receiving element 210 of external voice box 200 receives the voice signal that audio frequency transmitting element 140 sends; And through audio output unit 220 sounding; Thereby making the audio frequency of mobile phone put outward can to satisfy many people listens to, and the volume of sounding is bigger.
The above is merely preferred embodiment of the present invention, not in order to restriction the present invention, all any modifications of within spirit of the present invention and principle, being done, is equal to and replaces and improvement etc., all should be included within protection scope of the present invention.
