Abstract
A full-range sound has high-frequency sound columns of one to eight speakers, medium-frequency sound columns of one to eight speakers and low-frequency sound columns of one to two speakers. Layers are on a power amplifier stand, a front-level plate, a high-frequency rear-level plate, medium-frequency rear-level plate and a low-frequency rear-level plate are fixed on the layers and connected with the speakers with fine working frequency. The power amplifier stand is fixed in a low-pitch speaker. In the utility model, more speakers are provided, subdivided sound frequency is connected to the speakers with corresponding frequency, thus having ideal frequency response curve on the whole.
Description
Technical field
The utility model belongs to the loud speaker group in International Patent Classification (IPC), i.e. H04R, particularly whole tone sound equipment frequently.
Background technology
Voice signal is become the signal of telecommunication or mechanical signal, with the signal of telecommunication or the undistorted voice signal that is reduced into of mechanical signal, is all technical staff's of this field research topic then always.Now develop into high, medium and low loud speaker that separates or audio amplifier from single loud speaker.Along with going deep into of loud speaker manufacturing technology, can accomplish to segment the true reduction of a bit of audio frequency.Therefore at present simple rough segmentation two divided-frequency or three frequency division have satisfied not needs of society.Through Chinese patent information initial survey, fail to detect the technical scheme that solves an above-mentioned difficult problem.
The utility model content
The purpose of the utility model provides a kind of full range sound equipment, and it has numerous loud speakers, but the audio frequency that each autoreduction is segmented, thus comparatively ideal frequency response curve is arranged.
Realize that the technical scheme that above-mentioned purpose adopted is following:
A kind of full range sound equipment comprises high frequency sound column, intermediate frequency sound column and bass box, and the bass box internal fixation has power amplifier:
1-9 loudspeaker and alt loudspeaker and frequency divider are arranged in the high frequency sound column; 1-8 mediant trumpet arranged in the intermediate frequency sound column; 1-2 bass horn arranged in the bass box;
Power amplifier is installed on the power amplifier support of layering, step behind step and the high, medium and low sound before power amplifier support higher slice is fixed with, and its audio signal inserts said sound column, audio amplifier respectively.
Press the sound equipment of such scheme trial-production, have than multi-loudspeaker, but the audio frequency that each autoreduction is segmented.Integral body has comparatively ideal frequency response curve, reaches the effect of real full range.
Description of drawings
Fig. 1 is the overall schematic of an embodiment of the utility model.This routine high frequency sound column has 9 loudspeaker, and the intermediate frequency sound column has 8 loudspeaker; Bass box has 2 loudspeaker.
Fig. 2 is each loud speaker annexation sketch map of power amplifier support, each wiring board and present embodiment of Fig. 1 layering.
Fig. 3 is the enlarged drawing of Fig. 2 power amplifier support.
Wherein: 1, step behind step 15, the bass behind step 14, the middle pitch behind high frequency sound column 2, intermediate frequency sound column 3, bass box 4, frequency divider 5, power amplifier 6, loudspeaker 7, alt loudspeaker (reference frequency 1.2KHz-7KHz) 8, alt loudspeaker (reference frequency 400Hz-1.2KHz) 9, mediant trumpet (reference frequency 370-400Hz) 10, mediant trumpet (reference frequency 180Hz-370Hz) 11, bass horn 12, preceding step 13, the high pitch
Embodiment
A kind of full range sound equipment comprises high frequency sound column 1, intermediate frequency sound column 2 and bass box 3, and bass box 3 internal fixation have power amplifier 5:
1-9 loudspeaker 6 and alt loudspeaker 7,8 and frequency divider 4 are arranged in the high frequency sound column 1; 1-8 mediant trumpet 9,10 arranged in the intermediate frequency sound column 2; 1-2 bass horn 11 arranged in the bass box 3;
Power amplifier 5 is installed on the power amplifier support of layering, step 13,14,15 behind step 12 and the high, medium and low sound before power amplifier support higher slice is fixed with, and its audio signal inserts said sound column, audio amplifier respectively.
Audio signal inserts behind step 13 behind the high pitch, the middle pitch step 15 behind the step 14 and bass respectively, and behind power amplifier, inserts loudspeaker 6 and alt loudspeaker 7,8, mediant trumpet 9,10 and bass horn 11 respectively behind preceding step 12 frequency divisions.
Skilled in the art will recognize that the frequency behind the frequency division is not accurately absolute, also can adopt slightly variant frequency range.The scheme that this instance adopts is following:
The audio signal of step 13 behind the high pitch; Behind frequency divider 4 two divided-frequencies; High pitch cut-in operation frequency is the loudspeaker 6 of 7KHz-20KHz, and alt cut-in operation frequency respectively is the alt loudspeaker 7 of 1.2KHz-7KHz, and directly the cut-in operation frequency is the alt loudspeaker 8 of 400Hz-1.2KHz simultaneously; The midrange signals of step 14 behind the middle pitch, cut-in operation frequency respectively are that the mediant trumpet 9 of 370Hz-400Hz is the mediant trumpet 10 of 180Hz-400Hz with operating frequency; The following signal of the 180Hz of step 15 inserts bass horn 11 behind the bass.
Should, segment carefully more, the lifting or the fade performance of segmentation signal are good more, and whole frequency response is unreasonable to be thought.If only divide high, medium and low three sections, then become prior art.Preceding step 12 functions are high, medium and low total frequency division.Frequency divider 4 functions are the segmentation in the 1.2KHz-20KHz high pitch, and this example is divided into two sections, insert loudspeaker 6, mediant trumpet 7 respectively.
