Fig. 2 is the block diagram of an embodiment of the utility model;

Fig. 3 is the block diagram of another embodiment of the utility model.

Embodiment

Below in conjunction with accompanying drawing, the utility model is described in more detail.

Referring to Fig. 1, a kind of Mobile phone audiphone, comprise mobile phone body, be arranged on described mobile phone body surface MIC100, be arranged on dsp processor 104, output module 107 in described mobile phone body, also comprise: noise reduction filtering module 101, pre-amplification module 102, A/D analog-to-digital conversion module 103, D/A D/A converter module 105, signal enhancement module 106; Described MIC100 is connected with described noise reduction filtering module 101, described noise reduction filtering module 101 is connected with described pre-amplification module 102, described pre-amplification module 102 is connected with described A/D analog-to-digital conversion module 103, described A/D analog-to-digital conversion module 103 is connected with described dsp processor 104, described dsp processor 104 is connected with described D/A D/A converter module 105, described D/A D/A converter module 105 is connected with described signal enhancement module 106, and described signal enhancement module 106 is connected with described output module 107;

MIC is microphone, for sound, tidies up device, obtains voice signal, and voice signal is converted to analog electrical signal and sends this analog electrical signal to noise reduction filtering module; Noise reduction filtering module is carried out noise reduction process to the analog electrical signal receiving, to improve the signal to noise ratio of analog electrical signal; Pre-amplification module is tentatively amplified the analog electrical signal through noise reduction process, so that the sampling of follow-up A/D analog-to-digital conversion module; A/D analog-to-digital conversion module, by sampling, is converted to digital electric signal by analog electrical signal, gives dsp processor and processes, and the signal after processing by dsp processor, is sent to D/A D/A converter module and carries out digital-to-analogue conversion; D/A D/A converter module is converted to analog electrical signal by digital electric signal, gives the last amplification strengthening before signal enhancement module is exported; Analog electrical signal after signal enhancement module is amplified is sent to output module, and output module has two kinds of modes, two kinds of modes of earphone interface circuit and bluetooth sending module;

As shown in Figure 2, when output module is earphone interface circuit 1071, in the earphone jack that user only need insert common wired earphone 1081 on mobile phone, can hear the sound after amplifying;

As shown in Figure 3, when output module is bluetooth sending module 1072, user need to wear the bluetooth earphone 1082 that bluetooth sending module adapts therewith, bluetooth earphone 1082 through pairing, can receive the sound after amplification by blue teeth wireless load mode, by embedded with bluetooth sending module 1072 in mobile phone with Bluetooth of mobile phone sending module 1072, therewith suitablely, at far-end, wear bluetooth earphone 1082, can not be subject to the puzzlement of earphone cord, freely hear the sound after amplification.

Below described in conjunction with specific embodiments know-why of the present utility model, these are described is in order to explain principle of the present utility model, and can not be interpreted as by any way the restriction to the utility model protection range.Explanation based on herein, those skilled in the art does not need to pay performing creative labour can associate other embodiment of the present utility model, within these modes all will fall into protection range of the present utility model.
