Abstract

The utility model discloses a low frequency effect enhancing device of a sound box. The device comprises two passive loudspeakers, each of which consists of a vibration circle (1) and a passive basin (2); the two passive loudspeakers of the device are respectively and fixedly installed in the holes of brackets (3) adaptive thereto and located at two corresponding sides of a horn (7); and the two brackets (3) are respectively and fixedly connected with side plates (4) at two sides of the sound box, the interval between the bracket (3) and the side plate (4) forms an air chamber (5) which is communicated with an opening (6) on the edge of the side plate (4), and the opening (6) is communicated with atmosphere. The low frequency effect enhancing device solves the problem of obtaining the satisfied low frequency effect of the sound box by using smaller power drive, has the advantages of portability, energy conservation, and the like, and is widely applicable to sounding devices.

Description

The low-frequency effect intensifier of audio amplifier
Technical field the utility model relates to a kind of effect intensifier, more particularly, relates to a kind of low-frequency effect intensifier of audio amplifier.
Background technology in the prior art, the kind of audio amplifier has the inverted image formula, passive type and labyrinth type etc., but do not find that all audio amplifier has the low-frequency effect intensifier, sound equipment needs bigger input power could produce bigger sound pressure level, has that inconvenience is carried and the high shortcoming that consumes energy.
Utility model content the purpose of this utility model is to provide a kind of audio amplifier low-frequency effect intensifier that uses less power drive can obtain comparatively satisfied low-frequency effect.
In order to achieve the above object, the utility model provides following technical scheme: the low-frequency effect intensifier that designs a kind of audio amplifier, comprise two passive loud speakers that constitute by shake circle 1 and passive basin 2, two passive loud speakers of this device are fixedly mounted in the hole with its support that adapts 3 respectively and are positioned at the corresponding both sides of loudspeaker 7, two supports 3 are fixedlyed connected with the side plate 4 of audio amplifier both sides respectively, interval between support 3 and the side plate 4 constitutes air chamber 5, air chamber 5 communicates with opening 6 on side plate 4 edges, and opening 6 communicates with atmosphere.
Opening 6 of the present utility model preferably is positioned at the back side of audio amplifier, makes audio amplifier elegant in appearance.
Compared with prior art, the utlity model has following advantage: because the low-frequency effect intensifier is positioned at the both sides of Music centre loudspeaker, utilize the compression-expansion principle of air, make effective vibration area of loudspeaker convert effective vibration area of the passive basin of two low-frequency effect intensifiers to, make less power drive and less sound equipment size, can obtain comparatively satisfied low-frequency effect, adapted to portable, energy-conservation requirement.
Be description of drawings of the present utility model below the description of drawings:
Fig. 1 is a cross-sectional view of the present utility model;
The audio amplifier structure schematic diagram that Fig. 2 is;
Fig. 3 is the planar structure schematic diagram of audio amplifier side plate 4 and support 3.
In Fig. 1～3, the 1st, shake circle, the 2nd, passive basin, the 3rd, support, the 4th, side plate, the 5th, air chamber, the 6th, opening, the 7th, loudspeaker, the 8th, screw, the 9th, power line hole.
By specific embodiment the utility model is described in detail below the embodiment:
With reference to Fig. 1, the low-frequency effect intensifier comprises two passive loud speakers that are made of shake circle 1 and passive basin 2, two passive loud speakers are fixedly mounted in the hole with its support that adapts 3 respectively and are positioned at the corresponding both sides of loudspeaker 7, interval between support 3 and the side plate 4 constitutes air chamber 5, air chamber 5 communicates with opening 6 on side plate 4 edges, and opening 6 communicates with atmosphere.
With reference to Fig. 2, opening 6 is positioned at the back side of audio amplifier and communicates with atmosphere.
With reference to Fig. 3, support 3 is fixedlyed connected with the side plate 4 of audio amplifier both sides respectively, can fix by screw.
