Abstract
The utility model relates to a device for automatically adjusting volume of a mobile phone, which belongs to the technical field of volume control of a speaker of a mobile phone, in particular to a device for automatic adjustment of the volume of the mobile phone. The device comprises an MIC (microphone circuit) and a control module, wherein the control module comprises a noise value storage module, a volume adjustment module, a pulse signal generator and a noise value comparison module; and the MIC, the noise value storage module and the signal output end of the pulse signal generator are respectively connected with the signal input end of the noise value comparison module, the signal output end of the noise value comparison module is connected with the signal input end of the volume adjustment module, and the volume adjustment module is connected with the speaker of the mobile phone. By adopting the device, the volume of the speaker of the mobile phone can be adjusted automatically according to external noise, no manual operation of the mobile phone is needed, and users can get better sound experiences.
Description
Technical field
The utility model relates to mobile phone speaker volume regulation technology field, is specifically related to mobile phone volume size automatic regulating equipment.
Background technology
When mobile phone uses, as converse, listen to the music, broadcast receiver, hand-free call etc., generally ambient noise can change, the time little, clear when big.If ambient noise is bigger, the user wishes that the sound of receiver and loudspeaker is bigger; If the external environment noise is smaller, the user wishes that then the sound of receiver and loudspeaker diminishes.Traditional mobile phone does not also have to regulate according to ambient noise automatically the function of mobile phone speaker volume.Therefore need and to regulate the device of speaker volume automatically to realize this function according to ambient noise.
Summary of the invention
The technical problems to be solved in the utility model is: by a kind of device, solve the problem that traditional mobile phone cannot be regulated speaker volume automatically according to ambient noise.
To achieve the above object of the invention, the technical scheme that the utility model adopted is:
Automatically regulate the device of mobile phone volume size, comprise MIC and control module, described control module comprises a level of noise memory module, a volume adjusting module, a pulse signal generator and level of noise contrast module; The signal output part of described MIC, level of noise memory module and pulse signal generator is connected with level of noise contrast module by signal input respectively, the signal output part of described level of noise contrast module is connected with the signal input part of volume adjusting module, and described volume adjusting module is connected with mobile phone speaker.
This practical beneficial effect is: make mobile phone need not to regulate the mobile phone speaker volume automatically according to ambient noise under the situation of manual operation, experience so that the user obtains better sound.
Description of drawings
Fig. 1 is a structural representation of the present utility model;
Wherein, 1, MIC, 2, control module, 201, the level of noise memory module, 202, level of noise contrast module, 203, volume adjusting module, 204, pulse signal generator, 3, mobile phone speaker.
Embodiment
Below in conjunction with accompanying drawing embodiment of the present utility model is done and to be described in detail:
Automatically regulate the device of mobile phone volume size, comprise MIC1 and control module 2, described control module 2 comprises with lower module:
One level of noise memory module 201 is used to store the default level of noise of using for level of noise contrast module 202;
One volume adjusting module 203 is used for the noise reduced value control mobile phone speaker 3 according to 202 outputs of level of noise contrast module, regulates the mobile phone speaker volume;
One pulse signal generator 204 is used to emit pulse signal, and controlling noise value contrast module 202 is gathered the frequency of level of noise and generation noise reduced value from MIC1; And
One level of noise contrast module 202 is used for gathering level of noise with the frequency of pulse signal generator 204 controls from MIC1, presets the level of noise contrast again with in the level of noise memory module 201, at last to volume adjusting module 203 output noise reduced values.
The signal output part of described MIC1, level of noise memory module 201 and pulse signal generator 204 is connected with level of noise contrast module 202 signal input parts respectively, the signal output part of described level of noise contrast module 202 is connected with the signal input part of volume adjusting module 203, and described volume adjusting module 203 is connected with mobile phone speaker 3.
Operation principle of the present utility model is:
A, level of noise contrast the frequency of module according to pulse signal generator, regularly gather the default level of noise contrast of level of noise and level of noise memory module by MIC, calculate the noise reduced value.
B, volume adjusting module are controlled mobile phone speaker according to the noise reduced value of (a) output, regulate volume.
The utility model is not limited to above-mentioned example, in claims of the present utility model institute restricted portion, and various distortion that those skilled in the art can make without creative work or revise the protection that all is subjected to this patent.
