Abstract
This invention is an adjusting method of horn working parameter, the technological scheme is: the switching signal generator adopts the monolithic machine that can program online, use online programming method to adjust the working parameter of the switch control signals and make it match with the mechanic system of the horn and make the horn reach the best working state. This invention adopts the online programming, so it can make use of the modifying performance of the program parameter to automatically change the program parameter according to the characteristics of every horn, and automatically adjust the wave shape, the frequency and duty ratio of the switch controlling signal and make it match with the performance of the mechanic vibration and make every horn reach the best working state. In the production process, it writes the program into the chip after the assembling of the horn, so it further simplifies the producing techniques of horns and increases the productivity.
Description
Technical field: the control method that the present invention relates to a few thing parameters such as frequency of loudspeaker in a kind of loudspeaker production run.
Background technology: at present, the loudspeaker that use on the motor vehicle, its sounding principle all is to adopt adhesive and the release of electromagnet to vibrating diaphragm basically, excites air to sound by diaphragm again.And the adhesive of electromagnet with discharge to be by the connection of electric current in the magnet coil and to cut off to realize that along with the continuous break-make of electric current in the electromagnet, oscillating plate will be in the continuous shaking of the left and right sides of its equilibrium position, thereby excite air to sound.When the natural frequency characteristic of characterisitic parameter such as the frequency of pulse current and this mechanical vibrating system was complementary, whole horn system reached resonant condition, and loudspeaker will send maximum sound this moment, and the work efficiency of loudspeaker is the highest.In the electronic type loudspeaker, electric current is logical in the magnet coil, disconnected is to realize by transistor switching circuit, and the Push And Release of oxide-semiconductor control transistors switch utilizes switch signal generator to control, but because the characteristic of the mechanical vibrating system of loudspeaker, discreteness is very big, natural frequency particularly, requirement to indexs such as the waveform of switching signal and dutycycles, difference is bigger, if the control signal that signal generator produces, can not be well and the mechanical system characteristic be complementary, then the sounding effect of loudspeaker can be not fine, and work efficiency can be very not high yet, is difficult to guarantee the performance index of loudspeaker, thereby cause the production efficiency of loudspeaker very low, this is the comparatively general problem that exists during present loudspeaker are produced.
Summary of the invention: the objective of the invention is at above-mentioned problems of the prior art provide a kind of can be according to every mechanical property that loudspeaker are different, reprogramming parameter automatically, make it to be complementary, to adapt with the mechanical vibrating system characteristic, make every loudspeaker can both reach optimum Working, the control method of a kind of horn working parameter that production efficiency is high.Technical scheme of the present invention is: but switch signal generator of the present invention is the single-chip microcomputer that adopts online programming, adjust the running parameter of switch controlling signal with online programmed method, make it to be complementary with the characteristic of the mechanical vibrating system of loudspeaker, make loudspeaker reach optimum Working, concrete steps are as follows: 1, program does not write under the state of single-chip microcomputer, and single-chip microcomputer is assembled into loudspeaker inside; When 2, debugging, utilize the online programming device, thereby make the mechanical vibrating system startup work of loudspeaker by the work of DLL (dynamic link library) drives power driven system; 3, meanwhile detection system detects the intrinsic mechanical property of these loudspeaker by changing each correlation parameter of control signal; 4, the online programming device is adjusted relevant parameter in the switch drive program automatically according to this intrinsic mechanical property, makes it to be complementary with the intrinsic mechanical property of these loudspeaker.Thereby generate the target drives program of these loudspeaker; 5, the online programming device utilizes the target drives program, and loudspeaker are once driven test, if by test, just this driver is filed.Otherwise, carry out parameter testing again; 6, by the online programming device target drives program that obtains is write in the single-chip microcomputer of loudspeaker inside.The present invention is owing to adopt online programming, but thereby can utilize the change of program parameter, according to every mechanical property that loudspeaker are different, reprogramming parameter automatically, automatically adjust the waveform of switch controlling signal, parameter such as frequency and dutycycle, make it to be complementary with the mechanical vibrating system characteristic, adapt, make every loudspeaker can both reach optimum Working, can make product that the software of different editions is arranged, realize the upgrading of product, can produce different voice signals according to the different program of requirement of client editor again, thereby satisfy different levels client's demand.In process of production,, when needing, again program is write chip, further simplified the production technology of loudspeaker, improved production efficiency owing to be after the loudspeaker assembling is finished.
