Abstract
The utility model discloses a stereophonic voice box. The utility model is characterized in that the utility model is provided with a pair of ground voice boxes and a pair of wall voice boxes, and the ground voice boxes and the wall voice boxes are combined; the different positions and directions of the interiors of the ground voice boxes are respectively provided with an ultra-high tone loudspeaker, an intermediate bass loudspeaker and a bass loudspeaker and voice tubes and echo holes which match with the loudspeakers, and a frequency divider is arranged in each ground voice box; each wall voice box is provided with a downwards inclined high tone loudspeaker and a reflecting surface matching with the high tone loudspeaker. The utility model has the advantages of simple structure and low price; no other electronic circuits can match with a power amplifying machine except for the frequency divider; the utility model can obtain fourteen voice fields, and a satisfactory stereophonic effect can be obtained at any angle and any direction in a room.
Description
The utility model relates to a kind of audio amplifier that can improve stereo unit mahine tonequality, specifically a kind of comprehensive spatial stereo audio amplifier of brand-new design.
Present stereo unit mahine and audio amplifier are popularized in family gradually, and the loud speaker of traditional audio amplifier all is in (as 4 sound fields of a pair of main sound box and a pair of secondary audio amplifier composition) on the plane basically, people are in order to obtain satisfied stereophonic effect, requirement to the unit mahine class is also more and more higher, but still flat and stereo sound or the secondary flat and stereo sound (band is around the power amplifier on acoustic-electric road) heard do not have spatial impression, can only be middle equidistant tin of two audio amplifiers, if depart from either party, third dimension just obviously descends, can not listen to indoor walking about more, we can say not only complex circuit of the power amplifier that has surround sound common on the existing market, cost an arm and a leg, also still lack the reciprocal of duty cycle sense and have the orientation problem, tonequality and loudness are also not ideal enough.
It is a kind of simple in structure that the purpose of this utility model is to provide, and it is plentiful can both to obtain the sound battle array in indoor any direction and angle, and the comprehensive spatial stereo audio amplifier of the stereophonic effect of reciprocal of duty cycle sense is arranged.
The technical solution of the utility model is achieved in that it mainly comprises and lands audio amplifier, wall built-up audio amplifier and frequency divider, it is characterized in that: adopted a pair of audio amplifier and a pair of wall built-up audio amplifier of landing to make up; Landing the inherent Different Plane of casing and the position of audio amplifier is respectively arranged with superelevation sound, middle bass, woofer and sound pipe with matching or echo hole; Frequency divider is arranged on and lands in the audio amplifier; The reflecting surface that the wall built-up audio amplifier is provided with downward-sloping high pitch loudspeaker and matches with it.
Medium and low spectrum loudspeaker of the present utility model is arranged on and lands the top of audio amplifier, horn mouth up, super high pitch loudspeaker is positioned at the front of audio amplifier, horn mouth forward; At close place, middle part of landing audio amplifier one fully sheathed case is set also, woofer is loaded on the fully sheathed case, and horn mouth is downward; Be provided with the echo hole landing casing two sides and the back side of audio amplifier; High pitch loudspeaker in the wall built-up audio amplifier adopts horn extra-high-speed sound loud speaker, and inclined plane and reflecting surface that this loud speaker is downward-sloping are symmetry shape; Be installed in the frequency divider that lands in the audio amplifier and 4 frequency divisions are set carry out frequency segmentation, adopt transformer filtering coupling in middle bass frequency range.
The utility model makes up with its distinctive loudspeaker box structure, in the changing naturally of sound battle array vector, can reset out from all quarter, form comprehensive spatial stereo, land the left and right acoustic channels symmetry of audio amplifier and match with sound pipe or echo hole, the sound wave of the bugle extra-high-speed sound of wall built-up audio amplifier reflects after by the inclined plane downward radiation again, make the more clearly gradually plentiful and last spatial impression of formation of sound field, can can both obtain satisfied stereophonic effect in indoor any direction and angle, the utility model is simple in structure, no any sophisticated electronic circuit except that frequency divider can be used with the various power amplifiers of market sale.
