Abstract
The invention relates to loudspeaker box frequency divider fields in the field of loudspeakers, in particular to an electronic acoustic splitter. The electronic acoustic splitter comprises a left channel input unit and a right channel input unit, wherein the left/right channel input unit comprises a left/right loudspeaker correction EQ, bass loudspeaker high-pass filters, bass loudspeaker low-pass filters, high-pitch loudspeaker high-pass filters, high-pitch loudspeaker low-pass filters, delayers, by-pass switches, a left/right bass loudspeaker output and a left/right high-pitch loudspeaker output. The bass loudspeaker high-pass filters are in series connection with the bass loudspeaker low-pass filters and the bass by-pass switches to form a bass channel, the high-pitch loudspeaker high-pass filters are in series connection with the delayers, level regulators and the high-pitch by-pass switches to form a high-pitch channel, and the bass channel is in parallel connection with the high-pitch channel and then is connected to the left/right loudspeaker correction EQ. The acoustic splitter can well compensate nonlinearity of a loudspeaker and enable the voice to be more accurately restored, the tone quality is more comprehensive, and the loudspeaker conducts fully-flat sound production.
Description
Technical field
The present invention relates to the loudspeaker enclosure divider field in loud speaker field, refer more particularly to and a kind ofly can compensate the non-linear of loud speaker, make loud speaker all may accomplish the electronics partial device of completely smooth sounding.
Background technology
Traditional audio amplifier design, because single loudspeaker are difficult to realize 20Hz to 20KHz full bandwidth sounding, so conventionally need many sound of distinguishing sounding different frequency section, most audio amplifier all adopts two minutes system for electrical teaching, and minority audio amplifier has three tunnels or more partial.Make compound horn unit send the sound of different frequency range, just need to there is partial device that audio signal is divided into high pitch and bass signal, the partial device of traditional audio amplifier is to adopt power device as inductance, electric capacity etc. are realized, common way is monomer to be divided into several part frequency ranges then string together. suitable frequency is passed to suitable monomer to realize the effect of protection monomer and effectively to utilize power, but each monomer has it to be applicable to the frequency range of performance, if each monomer is given the signal of its full rate and just may be caused damage to monomer, coordinating between this class power partial device and loud speaker is difficult to reach optimum efficiency, and general loud speaker all can not be accomplished smooth sounding completely, traditional power partial device cannot compensate the non-linear of loud speaker.
Summary of the invention
Main purpose of the present invention is for for not enough described in above-mentioned background technology, provide a kind of digital signal processor (DSP) that utilizes to form the function and efficacy that multiple high-order digit filter is realized frequency division, provide a kind of high, intermediate frequency is bright and clear, active, the solid strong electronics partial device of low frequency.
The present invention is achieved through the following technical solutions:
A kind of electronics partial device, this electronics partial device comprises L channel input unit, R channel input unit, it is characterized in that: described left/right sound channel input unit comprises left/right loudspeaker rectification EQ, bass horn high pass filter, bass horn low pass filter, loudspeaker high pass filter, loudspeaker low pass filter, delayer, by-pass switch, the output of left/right bass horn, the output of left/right loudspeaker, described bass horn high pass filter and bass horn low pass filter, the series connection of bass by-pass switch forms bass channel, loudspeaker high pass filter and delayer, level regulator, the series connection of high pitch by-pass switch forms high pitch passage, after described bass channel is in parallel with high pitch passage, be connected to left/right loudspeaker and correct EQ.
Further, the left/right sound channel of described left/right sound channel input unit is corrected EQ with left/right sound channel loudspeaker and is connected, and left/right sound channel is directly directly communicated with bass by-pass switch simultaneously, and the rearmounted sound channel output of left/right sound channel is communicated with high pitch by-pass switch.
Preferably, described left/right loudspeaker rectification EQ is 11 sections of EQ.
By the technical program, realize electronics partial device, be that high and low audio section is born by different loudspeaker units, by filter, make dropping in different frequency ranges according to working separately of each frequency range, crossing phenomenon again after frequency division can not be created in part-frequency point and drops separately, good compensation loud speaker non-linear, make sound-reducing more accurate, tonequality performance is more comprehensive, and loud speaker is accomplished smooth sounding completely.
Accompanying drawing explanation
Fig. 1 is the structure flow chart of electronics partial device of the present invention.
Embodiment
With the next specific works flow process according to embodiment, the present invention is further described.
Electronics partial device of the present invention adopts digital form, with DSP, realizes partial, by two-way independently power amplifier promote the high and low sound loud speaker of audio amplifier.Audio signal enters after DSP, and first channel input signal is corrected EQ by the sound channel loudspeaker of 11 sections, and these sound channel loudspeaker are corrected EQ for compensating the non-linear of speaker of voice box.Sound channel loudspeaker are corrected EQ signal out will be divided into two-way, divide and be clipped to high and low sound passage.Bass channel has a high pass filter and low pass filter, filters out the signal component that bass horn can not fine sounding.High pitch passage has a high pass filter, after filtering out low frequency signal, arrive delayer and level regulator, because loudspeaker is conventionally smaller, sounding face is earlier, on audio amplifier, it can be more forward than bass horn sounding face, this delayer can be adjusted to and allow the sound of loudspeaker and the sound of bass horn arrive intelligent's ear simultaneously, and this is also the function that conventional power partial device cannot be accomplished.The level regulator of high pitch passage, also can be as required by high pitched signal paraphase, to meet the requirement of acoustic image for regulating the acoustic pressure between high and low sound loud speaker poor.
One's duty system for electrical teaching also can be used in above the two-wire partial loud speaker containing power partial device, will after all filter by-pass, with regard to becoming a two-wire of proofreading and correct with loud speaker, divide system for electrical teaching.Even on the audio amplifier of single line partial, use this partial device system also can acquire benefit, can proofread and correct with the EQ of partial device the non-linear of audio amplifier.
Certainly this electronics divides system for electrical teaching also can be used in the occasion of using traditional audio amplifier, in traditional audio amplifier is used, directly by by-pass switch, audio signal is directly exported without a minute system for electrical teaching.
More than open be only one embodiment of the present of invention, but the present embodiment is not limited only to this, and any those skilled in the art protect within spirit within the variation of consideration that can think of all should be considered as protection scope of the present invention at claims.
