Embodiment
Below in conjunction with drawings and Examples voice communication assembly of the present invention and method are described in further detail.
See also Fig. 1 and Fig. 2, the voice communication assembly 100 shown in the preferred embodiment of the present invention, it can be the portable terminal that mobile phone, personal digital assistant (PersonalDigital Assistant, PDA) etc. have function of voice communication.
In the present embodiment, this voice communication assembly 100 is mobile phone, and it comprises body 110, microphone 120 and circuit board 130.This microphone 120 is arranged on the body 110, and this circuit board 130 is built in the body 110.An integrated baseband chip 140 reaches a radio-frequency module 150 that is electrically connected with baseband chip 140 on this circuit board 130.
This microphone 120 is used for gathering the voice signal of a calling party, and this voice signal is converted to audio signal.These microphone 120 built-in amplifying circuits 122, this amplifying circuit 122 is used for audio signal is amplified processing.By regulating the particular circuit configurations of this amplifying circuit 122, can preset the multiplication factor to audio signal.For example, all be provided with the adjustable negative feedback resistor of resistance in a lot of amplifying circuits, be used for regulating multiplication factor.By regulating the resistance of the adjustable negative feedback resistor (not shown) of the resistance that arranges according to prior art in this amplifying circuit 122, just can change the multiplication factor of amplifying circuit 122.So, decibel less voice signal of calling party output can amplify according to the multiplication factor that sets in advance, thereby obtain an audio signal undistorted and decibel value is larger after microphone 120 is processed.
This microphone 120 is electrically connected with baseband chip 140, is sent to baseband chip 140 with the audio signal after will amplifying.Audio-frequency signal coding after the amplification that this baseband chip 140 is used for microphone 120 is transmitted becomes the base band code, and is sent to radio-frequency module 150.This radio-frequency module 150 is used for this base band code of modulation, and is sent to the side of answering by the antenna (figure is mark not) of voice communication assembly 100, so that the side of answering sets up voice communication with calling party.
As a kind of preferred implementation, a control button 112 further is set on the body 110 of voice communication assembly 100 of the present invention, this control button 112 is used for regulating the resistance value of above-mentioned negative feedback resistor, and then changes the multiplication factor of this amplifying circuit 122.So, calling party can be according to the multiplication factor of the real-time manual adjustments microphone 120 of conversation environment.In addition, the multiplication factor of this microphone 120 can also show by the display screen (not shown) of voice communication assembly 100, so that calling party observation.
As a kind of preferred implementation, an options button 114 also further is set on the body 110 of voice communication assembly 100 of the present invention, this options button 114 is used for enabling amplifying circuit 122, to start the function of amplifying audio signal.So, whether the user can start amplifying circuit 122 according to concrete conversation environmental selection, in order to do not start amplifying circuit 122 under the unrestricted environment of sound of speaking, the impact side of answering answers in order to avoid sound is excessive.
Specify the operation principle that this voice communication assembly 100 is used for regulating voice below in conjunction with Fig. 3, namely the described voice communication method of preferred embodiment of the present invention comprises the steps: at least
Step S1: whether calling party starts amplifying circuit 122 according to the conversation environmental selection, if when calling party is in a minute the restricted environment of sound (such as the library), and execution in step S2 then; If calling party is in when speaking the unrestricted environment of sound (such as family), then carry out an existing voice communication mode, do not repeat them here.
Step S2: calling party enables amplifying circuit 122 by options button 114, to start the function of amplifying audio signal.
Step S3: calling party is by the multiplication factor of control button 112 setting amplifying circuits 122, and this multiplication factor shows by display screen.
Step S4: microphone 120 gathers the voice signal of calling party, and this voice signal is converted to audio signal.
Step S5: microphone 120 amplifies processing by amplifying circuit 122 with audio signal, and the audio signal after will amplifying is sent to baseband chip 140.
Step S6: the audio-frequency signal coding after baseband chip 140 will amplify becomes the base band code, and is sent to radio-frequency module 150.
Step S7: radio-frequency module 150 is modulated these base band codes, and is sent to the side of answering by the antenna of voice communication assembly 100, and then so that the side of answering sets up voice communication with calling party.
Be appreciated that options button 114 of the present invention can omit.So, directly the multiplication factor by control button 112 amplifying circuits 122 is set to 1 and gets final product.Corresponding above-mentioned steps S1-S2 can omit.
If be appreciated that above-mentioned steps S3 can omit when current amplifying circuit 122 predefined multiplication factors met the calling party demand.
Voice communication assembly of the present invention 100 amplifies audio signals by microphone 120, even so that during the less voice signal of calling party output decibel, also can make and answer Founder and often answer, and has effectively improved speech quality.In addition, microphone 120 of the present invention amplifies by 122 pairs of audio signals of self integrated amplifying circuit, and with respect to the mode that tradition uses speech chip independently that audio signal is amplified, its design cost is lower.
The above, it only is preferred embodiment of the present invention, be not that the present invention is done any pro forma restriction, although the present invention discloses as above with preferred embodiment, yet be not to limit the present invention, any those skilled in the art, within not breaking away from the technical solution of the present invention scope, when the technology contents that can utilize above-mentioned announcement is made a little change or is modified to the equivalent embodiment of equivalent variations, in every case be not break away from the technical solution of the present invention content, any simple modification that foundation technical spirit of the present invention is done above embodiment, equivalent variations and modification all still belong in the scope of technical solution of the present invention.
