Embodiment Construction

[0022] The present invention will be further described below in conjunction with specific drawings and embodiments.

[0023] As shown in the figure, the multi-point excitation source sound box with heat dissipation structure in the embodiment is mainly composed of a front cavity 1 , a rear cavity 2 , a woofer unit 3 and a middle and high pitch speaker unit 4 .

[0024] Such as Figure 1~Figure 6 As shown, the front cavity 1 and the rear cavity 2 form a prolate box, and the front cavity 1 is provided with two woofer mounting holes 1a in the length direction, and the two woofer units 3 are correspondingly installed on the two The two woofer units 3 are coplanar and coaxially arranged, and their sound radiation direction is toward the front of the box, and the performance specifications of the two woofer units 3 are completely consistent.

[0025] Such as Figure 1~Figure 6 As shown, a short side of one end of the front cavity 1 is provided with a mid-tweeter front half mountin...

Abstract

The invention relates to a multipoint excitation source sound box with a radiating structure. The sound box comprises a box body and is characterized in that the box body is long and flat, at least two low pitch loudspeaker installation holes are formed in a front panel of the box body in the length direction, and a low pitch loudspeaker unit is installed in each low pitch loudspeaker installation hole. The low pitch loudspeaker units are arranged coaxially on the same plane, and sound of the two units are radiated towards the front of the box body. A high-mid pitch loudspeaker installation hole is formed in one short side of one end of the box body, and a high-mid pitch loudspeaker unit is installed in the high-mid pitch loudspeaker installation hole. The sound radiation direction of the high-mid pitch loudspeaker unit is perpendicular to the sound radiation direction of a front high pitch loudspeaker unit, and the high-mid loudspeaker unit is coaxial with all the low pitch loudspeaker units. The multipoint excitation source sound box has the advantages of being ingenious in structure, small in size, thin in structure, good in long time operation sound performance and good in reliability.

Description

technical field [0001] The invention relates to a loudspeaker sound box, in particular to a multi-point excitation source sound box with a heat dissipation structure suitable for use on a television set, and belongs to the field of electroacoustic technology. Background technique [0002] In the prior art, speakers used in flat-panel televisions such as LCDs and OLEDs are generally required to have the characteristics of small size, thin structure, high power, and good sound. Traditional TV speakers usually use a single speaker to form a speaker. Although the volume and structure can meet the requirements, the sound performance is not good and the power it can withstand is not large. The sound performance of the speaker composed of multiple speaker units is improved, but due to the increase in the number of speaker units, it is easy to cause poor heat dissipation, which in turn leads to poor reliability and failure to work normally after long-term operation.
