Description
Technical field
The present invention relates to a kind of electronic-controlled installation, particularly, be a kind of can be by the sound-controlled apparatus of original sound volume output sound.
Background technology
At present, any electronic product of sounding all has the function of regulating volume, promptly makes a little less than the volume down according to user's needs or strengthens, to reach the purpose that adapts to different occasions, different user.This function is compared with the phonograph of the no volume control function of Edison's invention, it no doubt is very big progress, but simultaneously, also cause a unavoidable problem, promptly in the real life, the volume range of original sound is relatively-stationary, as the cry of insect, people's one's voice in speech, live concerts etc., when electronic product was recorded or simulated original sound, the volume of sound was uncontrollable; And when playing these sound,, will change the volume of sound reality because player itself has volume adjusting function, and with original sound volume a certain distance is arranged, though sound itself is also undistorted, want to hear but to be not easy the effect of original sound to realize.
Summary of the invention
The object of the present invention is to provide a kind of sound-controlled apparatus, both can regulate the size of volume according to actual needs, also can recover the original sound volume of sound,, thereby address the above problem even the volume that electronic product is play need to equal the sound simulating, reset and the volume of prevailing circumstances.
Sound-controlled apparatus of the present invention comprises the simulation/synthetic/playback circuitry, output circuit, audio-amplifying circuit and a loudspeaker and the output selector switch that are linked in sequence, it is characterized in that: also comprise a single-chip microcomputer and D/A change-over circuit and an electronic switch; Described single-chip microcomputer and D/A change-over circuit are connected in series, and described single-chip microcomputer is output as input with simulation/synthetic/playback circuitry, and described D/A change-over circuit is connected with a moving contact of electronic switch; The output terminal of described output circuit is connected with another moving contact of electronic switch, and the stationary contact of described electronic switch is connected with audio-amplifying circuit, after being amplified by audio-amplifying circuit, sends loudspeaker to; Described output selector switch control electronic switch; During described output selector switch cut-off/close, electronic switch is connected with output circuit, and the volume of output is adjustable; During described output selector switch closure/disconnection, electronic switch is connected with single-chip microcomputer, and the size of the sound of output equates with original source of sound, promptly by programming on single-chip microcomputer realize will output volume be fixed as the size of original source of sound.
Sound-controlled apparatus of the present invention, wherein said single-chip microcomputer adopts 51 series of Intel, or the PIC of MicroChip, or the Z80 of Zlog, or the HC11/12 of Motorola.
Sound-controlled apparatus of the present invention, wherein said output selector switch adopt the switch of pure machinery control.
Implementation procedure of the present invention is:
● on prior art, increase by an output selector switch, between adjustable output of volume and original sound volume output, finish switching, and finish adjustment different volumes by the interlock circuit mode of software combination (the pure hardware mode or the hardware with).
● under the state of original sound volume output, for the product of simulated sound class, the automatically calibrating volume makes it to equate with the source sound volume of being simulated; For the product of the environmental classes of resetting, from the normal moveout correction wave volume to reach consistent with the volume of collecting this environment.
● when this electronic product start, original state is the state of original sound volume output, if want to adjust volume, then pushes the state of the adjustable output of volume.
The present invention can make its volume equal that itself simulates, the device in real world or the volume of object for the electronic product of analogue type; For the electronic product of playback type, can make its volume equal to collect at that time the volume of this environment.So just can allow the user in using the process of electronic product, impression is more really arranged, when playing the piano, if sound that fender sends and real piano voice equate that user just has the impression that plays the piano more really.The disc that machine sowing is put for disc is an example by the live concert version for another example, if sound is the same with the sound of collecting the concert environment at that time, then the hearer has more real presence.
