Embodiment
The utility model provides a kind of mobile phone that can improve the tonequality of recorded video, for purpose, technical scheme and the effect that makes the utility model is clearer, clear and definite, below with reference to accompanying drawing and give an actual example to the utility model further explain.Should be appreciated that specific embodiment described herein only in order to explanation the utility model, and be not used in qualification the utility model.
The mobile phone of the utility model first embodiment; As shown in Figure 2, comprise a mobile phone body 200, be arranged on mobile phone body 200 back sides camera 201, be arranged on the first positive microphone 204 of mobile phone body 200; And be arranged on the mobile phone baseband process chip 203 and audio devices 202 in the mobile phone body 200; Said camera 201 is connected with mobile phone baseband process chip 203, and said first microphone 204 is connected with audio devices 202, wherein; Said mobile phone also comprises: one is arranged on second microphone 205 on said camera 201 limits, and said second microphone 205 is connected with said audio devices 202.
The mobile phone 200 that Fig. 2 embodiment provides can be used for video shooting; First microphone 204 is used to collect user's speech; Second microphone 205 is used for collecting video recording sound; Said first microphone 204 is arranged on the front that screen is arranged of mobile phone; Said second microphone 205 is arranged on the position of the mobile phone back side near camera 201, and said first microphone 204 and second microphone 205 are given described audio devices 202 with the transmission of sound signals of collecting, and sends said mobile phone baseband process chip 203 to through said audio devices 202.
Said audio devices 202 connects two microphones to be imported as voice data, and this first microphone 204 and second microphone 205 are the mobile phone speech input equipment.
In the present embodiment, first microphone 204 is as main audio input use, after audio devices 202 receives the audio frequency input from first microphone 204; Carry out Audio Processing; For example analog digital conversion, audio gain adjustment etc. then, are handled by mobile phone baseband process chip 203; For example, be transferred to network the other side, recording and the storage etc. in Tonghua.
