Abstract

The invention belongs to the technical field of electronic information and automatic control, and discloses motion earphones capable of adjusting volume automatically according to environment noises and motion speed. The motion earphones capable of adjusting volume automatically mainly comprise a speed detection module, a noise collecting module, an operation treatment module, a control module and a volume output module. Firstly, setting a volume constant; then carrying out preliminary data collection through the speed detection module and the noise collecting module; then transmitting the data to the operation treatment module, and calculating the total volume by the operation treatment module; and finally controlling the volume output module to output the volume through the control module. Through detecting and determining the environment of users and the motion variation condition, the volume is adjusted automatically in real time, the artificial operation is reduced, and the motion earphones capable of adjusting volume automatically are simple and convenient to use, are humanized, and are suitable for being used in motion.

Description

A kind of motion earphone of automatic regulating volume

Technical field

The invention belongs to electronic information and automatic control technology field, relate more specifically to a kind of can be according to the motion earphone of environmental noise and movement velocity automatic regulating volume.

Background technology

In the present life, can see the figure of earphone everywhere,, in outdoor, various English Listening Comprehension examination or the like, all can't do without earphone at home.Earphone is from inventing till now, and also the progress of Along with people's science and technology is constantly developing.

Along with the development of time, the earphone product hangs in one's ear from the earliest two little audio amplifiers and moves to maturity gradually.No matter be the kind or the wearing mode of earphone, even, a lot of changes has been arranged all to the pronunciation unit of core.

Earphone is exactly two pronunciation unit that hang on the ear the earliest, has developed till now many types, and the bone conduction earphone that has earphone, earplug, ear-hang and new development to come out substantially, headphone are headset types the earliest.

Earplug is that the revolutionary character of earphone development breaks through, and littler volume makes very easy to use outside, because development of city, environmental noise is increasing, and In-Ear earplug is a kind of breakthrough of earplug product again, and is more suitable in outdoor application.

People be unable to do without the use of earphone gradually in life, on road on and off duty, at the volley; All possibly wear the earphone mood of releiving of listening to the music aboard, wearing headphones at the volley is because the noise pollution in the frequency change of motion and city is more and more serious; At outdoor application common headphones earplug, volume can't be regulated automatically, will influence the effect of listening to; And volume is placed in the bag with regard to needing artificial regulate control, especially musical instruments, adjusts volume after the adjustment volume also need be searched equipment; In public places, reduced the fail safe of the personal effects, and do not hoped under the quiet environment that when the user turns back to earphone is too loud; Need regulate volume again again, trouble so just seems.

Summary of the invention

The purpose of this invention is to provide and a kind ofly can gather noise, detect movement velocity and can be under varying environment, the volume of regulating earphone according to the size of the decibel of noise and movement velocity automatically controls.

As shown in Figure 1, technical scheme of the present invention mainly comprises speed detection module, noise gathering module, calculation process module, control module, volume output module; The course of work is at first to set the volume constant; Carry out the preliminary data collection through speed detection module and noise gathering module then; Then transfer of data is arrived the calculation process module, after the calculation process module is calculated total volume, volume is exported through control module control volume output module.

The speed detection module is to comprise two signal sources, successively launches two paths, and the wavelength and the speed of emission are known, its movement velocity of phase in-migration measuring and calculating that produces during motion.

The noise gathering module is input to volume with the loop noise decibels that collects and regulates code table, finds the output volume gain value of magnification of ambient noise decibels correspondence in code table of input.

Control module obtains total volume with the noise decibel of the speed of speed monitoring module and the collection of noise gathering module after with the addition of volume constant.

The present invention can automatic regulating volume, judges residing environment of user and motion change situation through detecting, and real-time automatic regulating volume reduces manual operation, and is easy to use, and hommization more is fit to use in the motion.

Embodiment

For clear statement implementation process of the present invention, specifically describe the process that the motion earpiece volume is regulated below.

As shown in Figure 2, at first set the volume constant, carry out the preliminary data collection through speed detection module and noise gathering module then; When the user was in outdoor public place, the speed detection module was to comprise two signal sources, can be that LASER Light Source is successively launched two paths; The wavelength and the speed of emission are known, detect people's movement velocity, and the noise gathering module is gathered outdoor noise; The loop noise decibels that collects is input to volume and regulates code table; Find the output volume gain value of magnification of ambient noise decibels correspondence in code table of input, then transfer of data is arrived the calculation process module, after the calculation process module is calculated total volume; Through control module control volume output module volume is exported, volume increases with environment automatically.

When from outdoor get back to indoor; The people sit or lie keep static after, the speed detection module is launched the phase in-migration deduction speed that two paths do not produce and is about 0; And the noise decibel that the noise gathering module is gathered reduces; Then the calculation process module only with after noise decibel and the addition of volume constant, is input to control module, last output volume.
