Abstract

The utility model relates to a honeycomb sound box. At least one low frequency speaker unit is fixed on a panel of a box body of the utility model. The inner part of the box body is uniformly divided into honeycomb cavity bodies by a plurality of partition plates which are staggered to be connected. The cavity body can be square, or can be triangular, or can be polygonal. The sound box leads the box body to be an optimum rigid body, effectively inhibits the harmful resonance of the box body, and avoids the phenomena that sound is distorted and standing waves are in the box body. The utility model has a linear damping effect on the operation of a low frequency unit, reduces the distortion of sound, and leads the tone color of low frequency to be pure and clear.

Description

Cellular audio amplifier
The utility model relates to a kind of cellular audio amplifier, is the acoustic electroacoustic equipment of a kind of generation.
Audio amplifier is assembled by casing and loudspeaker unit coupling.Existing sound box mostly is empty van, and when loudspeaker cone vibrated, empty van was easy to generate resonance and case standing internal wave effect, thereby causes interference and sound to the woofer sound equipment to dye, and destroyed the purity of low frequency sound equipment, influenced auditory effect.
This reality and novel purpose provide a kind of cellular audio amplifier, and can suppress the resonance and the standing wave of casing effectively, the sound of eliminating the low frequency sound equipment dyes, and makes tone color clear, pure, improves auditory effect.
The utility model audio amplifier has a casing, at least be fixed with a woofer unit on the cabinet panel, evenly be separated into cellular cavity with a plurality of staggered dividing plates that link to each other in the casing, each honeycomb cavity can be any one geometry in square, triangle, the polygon, is good with hexagon wherein.The quantity of cavity and physical dimension can be according to casing and the comprehensive electro mechanical parameter designs of loud speaker.
This audio amplifier makes the cellular a plurality of cavitys that form uniformity in the case by the staggered dividing plate that links to each other, thereby makes audio amplifier become a best rigid body, has suppressed the harmful resonance of casing to greatest extent, has stopped sound and has dyed harm.Cellular cavity can be stopped case standing internal wave phenomenon effectively, and its reasonable distribution on the case interior mechanics is played more linear damping action to the running of low frequency cell, thereby reduced the distortion of audio amplifier effectively, makes the bass colour purity true, clear, and auditory effect improves.
Below in conjunction with description of drawings example structure of the present utility model.
Fig. 1 and Fig. 2 are the example structure schematic diagrames that casing contains the utility model audio amplifier in hexagon honeycomb chamber.
Fig. 3,4, the 5th, casing contain the structural representation of another embodiment of the utility model audio amplifier in square honeycomb chamber.
As shown in Figure 1, on the panel 1 of casing 3 woofer unit 2 is housed, 4 staggered the linking to each other of dividing plate in the casing 3 form cellular cavity 5.Fig. 2 is the stereogram of casing 3 among Fig. 1, and from Fig. 2 as seen, honeycomb chamber 5 is a hexagon, and the height of dividing plate 4 by cabinet wall to center position decrescence.
Among Fig. 3,4,5 embodiment, woofer unit 2 and two are housed on the panel 1 of case 3 swing to pipe 6,4 crisscross linking to each other of dividing plate in the casing 3 form square honeycomb chamber 5 (seeing Fig. 4,5), the height of dividing plate 4 by tank wall to the center position of casing (see figure 4) decrescence.

Claims (3)

1. cellular audio amplifier comprises casing and panel, is fixed with a woofer unit on the panel at least, it is characterized in that evenly being separated into cellular cavity with a plurality of staggered dividing plates that link to each other in the casing.
2. cellular audio amplifier according to claim 1 is characterized in that said cellular cavity is any one geometry in square, triangle, the polygon.
