Abstract
The utility model discloses a mobile terminal, which comprises a housing and a baseband circuit, as well as a signal processor for carrying out superimposed attenuation processing on audio data signals, a master microphone and a slave microphone, wherein the signal processor is connected with the baseband circuit, and the master microphone and the slave microphone are respectively connected with the signal processor. Compared with the existing mobile terminal, the mobile terminal comprises the master microphone and the slave microphone which are mounted in different positions; as the sound of a user can produce great difference when achieving the two microphones, and the environmental noise only has very small difference when achieving the two microphones, the application of the signal processor for carrying out superimposed attenuation can eliminate the noise and further effectively improve the sound quality effect during the communication process or the voice recording process; furthermore, the mobile terminal has the advantages of low cost and easiness in implementation.
Description
[technical field]
The utility model relates to a kind of portable terminal, relates in particular to a kind of portable terminal that can effectively reduce environmental noise to the tonequality influence.
[background technology]
Along with the develop rapidly of mobile communication technology, the application of portable terminal is also universal day by day.Mobile phone of today changes a kind of multi-function device into from simple conversation instrument.The user not only can make a phone call with it, and can record a video by it/record, take pictures, send note/video/audio, browsing page, receiving and dispatching mail and play games etc.Not ccontaining doubting, the portable terminal with numerous functions like this has enriched dramatically with facility people's life.Yet; because the portability of portable terminal; the user usually can be in and call in the noisy environment or record a video/record; like this; the portable terminal of application traditional structure (as shown in Figure 1; comprise loud speaker, baseband circuit and a microphone of connecting successively); the various noises of surrounding environment can have a strong impact on the acoustical quality of the voice in conversation/video recording/Recording Process; for the user brings inconvenience, thereby be necessary to propose a kind of portable terminal that can effectively reduce environmental noise to the tonequality influence.
[summary of the invention]
Technical problem to be solved in the utility model provides a kind of portable terminal, can effectively improve the acoustical quality that portable terminal transmits or records in noisy environment.
In order to solve the problems of the technologies described above, the technical solution adopted in the utility model is:
A kind of portable terminal comprises housing and baseband circuit, also comprises being used for voiceband data signal the superpose signal processor of attenuation processing, main microphone and from microphone; Described signal processor is connected with baseband circuit, described main microphone be connected with signal processor respectively from microphone.
Wherein, also comprise loud speaker, this loud speaker links to each other with described baseband circuit.
Wherein, described main microphone is installed on the bottom in described housing front, the described top that is installed on described back side of shell from microphone.
The utlity model has following beneficial effect:
Compare with existing portable terminal, the utlity model has the main microphone that is installed on diverse location and from microphone, because user's sound differs greatly when arriving two microphones, and environmental noise difference when arriving two microphones is very little, decay abates the noise so the utilization signal processor superposes, thereby has effectively improved in the communication process or the acoustical quality in the voice recording process; And has the advantage that cost is low, be easy to realize.
[description of drawings]
Below in conjunction with the drawings and specific embodiments the utility model is described in further detail:
Fig. 1 is the structural representation of existing portable terminal;
Fig. 2 is a structural representation of the present utility model.
[embodiment]
See also Fig. 2, this figure is depicted as the structural representation of portable terminal in the present embodiment, the loud speaker that comprise baseband circuit, is connected with baseband circuit respectively and signal processor and the main microphone that is connected respectively with signal processor and from microphone, wherein,
Main microphone near the position of user's face when talking (for example is installed on, be installed on the lower position in the front of mobile terminal shell), (for example be installed on from microphone away from the position of main microphone, be installed on the upper position at the back side of mobile terminal shell), main microphone and all be used to receive extraneous voice (comprising sound and environmental noise that the user sends) from microphone;
Signal processor, be used to handle main microphone and from the received voice of microphone, utilize that the received user voice of principal and subordinate's microphone differs greatly, received environmental noise difference features of smaller, to the voice attenuation processing that superposes, with the purpose that realizes abating the noise.
Therefore, use the portable terminal in the present embodiment, can effectively reduce the influence of external environment to tonequality, guaranteed the definition of voice in smooth and easy and institute's recording audio/video that both call sides exchanges.
Above embodiment is only unrestricted in order to the explanation the technical solution of the utility model, only with reference to preferred embodiment the utility model is had been described in detail.Those of ordinary skill in the art should be appreciated that and can make amendment or be equal to replacement the technical solution of the utility model, and do not break away from the spirit and scope of technical solutions of the utility model, all should be encompassed in the middle of the claim scope of the present utility model.
