In the utility model, through the MIC noise reduction chip and the earphone power amplifying chip which are installed in the mobile phone, noise reduction and filtering processing are carried out on background noise in input sound signals, and clear voice conversation audio signals are output. In addition, the voice conversation audio signal is amplified through the earphone power amplifying chip, and the amplified signals are directly input through a high-frequency amplification earphone. Compared with the prior art, the utility model has simple structure, is easy to realize, can effectively solve the problem that users who have dysaudia are inconvenient to use mobile phones.
Description
Technical field
The utility model relates to mobile phone, particularly a kind of mobile phone with hearing-aid function.
Background technology
The popularity rate of mobile phone use at present is more and more higher, and mobile phone has become necessary tool in people's daily life work.But in real life, have a lot of hearing to have the user of obstacle, they have difficulties in the process of using mobile phone communication, especially are in the bigger place of environmental noise, often can not the well-known intention of understanding the other side from call-information.
Summary of the invention
For addressing the above problem, the purpose of this utility model is to provide a kind of mobile phone with hearing-aid function, is built-in with earphone power amplification chip in this mobile phone, to realize that the voice call audio signal of input is amplified output.
For achieving the above object, the utility model is mainly by the following technical solutions:
A kind of mobile phone with hearing-aid function, comprise casing, be installed in the main process chip (104) in the casing, the one MIC (101), the 2nd MIC (102), MIC noise reduction chip (103) and earphone power amplification chip (105) also are installed in the described casing, a described MIC (101), the 2nd MIC (102) are connected with main process chip (104) by MIC noise reduction chip (103), and described main process chip (104) is connected with earphone power amplification chip (105).
Described earphone power amplification chip (105) is connected with earphone (106).
Described earphone (106) amplifies earphone for high frequency.
A described MIC (101) is for gathering the microphone of environmental noise audio signal.
Described the 2nd MIC (102) is for gathering the microphone of voice call audio signal.
The utility model is by installing MIC noise reduction chip and earphone power amplification chip in mobile phone, to realize that the background noise in the input audio signal is carried out the noise reduction filtration treatment, and export voice call audio signal clearly, and by earphone power amplification chip this voice call audio signal is amplified, amplify earphone by high frequency and directly import.Compared with prior art, the utility model is simple in structure, realization is easy, can effectively solve hearing and exist the user of obstacle to use the inconvenience of mobile phone.
Description of drawings
Fig. 1 is a theory diagram of the present utility model.
Identifier declaration among the figure a: MIC 101, the 2nd MIC 102, MIC noise reduction chip 103, main process chip 104, earphone power amplification chip 105, earphone 106, voice call signal 107.
Embodiment
Core concept of the present utility model is: the utility model is provided with MIC noise reduction chip and earphone power amplification chip in mobile phone inside, MIC noise reduction chip carries out noise reduction process to the audio signal of input, and voice call signal behind the noise reduction sent to main process chip, by main process chip above-mentioned voice call signal being carried out classification regulates, by earphone power amplification chip it is carried out secondary then and amplify, amplify earphone output by high frequency afterwards.
For setting forth thought of the present utility model and purpose, the utility model is described further below in conjunction with the drawings and specific embodiments.
See also shown in Figure 1ly, Fig. 1 is a theory diagram of the present utility model.The utility model provides a kind of mobile phone with hearing-aid function, include casing, be installed in a MIC 101, the 2nd MIC102, MIC noise reduction chip 103, main process chip 104 and earphone power amplification chip 105 in the casing, a described MIC 101, the 2nd MIC 102 are connected with MIC noise reduction chip 103 respectively, MIC noise reduction chip 103 is connected with main process chip 104, and described main process chip 104 is connected with earphone power amplification chip 105.
Wherein a MIC 101 is mainly used in and gathers the environmental noise audio signal, the 2nd MIC 102 then is used to gather the voice call audio signal, the one MIC 101, the 2nd MIC 102 are input to the audio signal that collects in the MIC noise reduction chip 103, handle by 103 pairs of environmental noises of MIC noise reduction chip (background noise), to guarantee the main process chip 104 that enters into of voice call signal complete display that the 2nd MIC 102 gathers.
In addition in communication process, also have the voice call signal 107 of automatic network to enter into main process chip 104, by main process chip 104 it being carried out classification regulates, and it is carried out one-level amplify, then this voice call signal 107 is input in the earphone power amplification chip 105, by earphone power amplification chip 105 it is carried out secondary and amplify, after amplifying by acc power amplification chip 105, can reach the power output of 150mW, amplify earphone 106 outputs by high frequency.
The principle of noise reduction of the utility model MIC noise reduction chip is as follows: the difference when at first utilizing voice and noise sound wave to arrive two microphones is handled by DSP, thereby picks up voice and repel environmental noise; The characteristic (tone, speed, harmonic wave) of utilizing human speech is then further extracted useful voice signal and compacting noise from noise, then utilize psychologic acoustics theory (screening model, based on artificial cochlea's filter array, dynamic range control etc.) to improve the characteristic of useful voice afterwards.
The hearing aid pattern that the utility model adopts mainly contains two kinds, a kind of is the hearing-aid function of call mode, voice signal is through mobile phone network input handset, main process chip outputs to the earphone power chip after this speech signal is handled amplification, amplify the rear drive earphone once more, reach needed volume, to finish the conversation hearing-aid function.
Another kind is common hearing-aid function, by this function of special key switch opens in the mobile phone, Zhou Wei sound imports into to a MIC and the 2nd MIC by different paths afterwards, processing through MIC noise reduction chip, background noise is handled, entered main process chip clearly so that guarantor's voice signal is complete, main process chip outputs to earphone power amplification chip after audio signal is amplified, can regulate gain amplifier in main process chip inside, reach the function that volume is regulated.Earphone power amplification chip amplifies the rear drive earphone to audio signal again, reaches the volume that needs, and finishes common hearing-aid function.
More than be that a kind of mobile phone with hearing-aid function provided by the utility model is described in detail, used specific case herein structural principle of the present utility model and execution mode are set forth, above embodiment just is used for helping to understand method of the present utility model and core concept thereof; Simultaneously, for one of ordinary skill in the art, according to thought of the present utility model, the part that all can change in specific embodiments and applications, in sum, this description should not be construed as restriction of the present utility model.
