Problems solved by technology

However, currently on the market, there is still a lack of a playback device that can accommodate high-frequency speakers and low-frequency speakers at the same time, and at the same time improve the problem of high-frequency directivity and mutual interference between speakers.

Embodiment 1

[0022] Example 1: see attached Figure 1-2 As shown, a full-range surround sound playback device 1 includes a box body 10, four high-frequency speakers 20 and a low-frequency speaker 30. The structure of each component and the relationship between them are described in detail as follows:

[0023] as attached figure 1 As shown, the box body 10 is a hollow quadrangular pyramid, which has a bottom wall 11 , a side wall 12 , a support portion 13 and a top wall 14 . The side wall 12 is annularly arranged above the bottom wall 11 , and the bottom wall 11 and the side wall 12 together define a sound cavity 15 to enhance the resonance effect of the sound waves emitted by the playback device 1 . The support portion 13 is disposed below the bottom wall 11 , the bottom wall 11 and the support portion 13 together form a cavity 16 , and the side wall of the support portion 13 is provided with four bass outlets 131 at equal angles in different directions to form a surround sound effect Ef...

Abstract

The invention discloses a sound effect play apparatus. The apparatus comprises a box body, a low-frequency loudspeaker and at least two high-frequency loudspeakers. A support portion is arranged below the box body. The support portion is provided with a plurality of bass outlets. The low-frequency loudspeaker is arranged on a bottom wall of the box body and a sound transmission direction is downward. And the high-frequency loudspeakers surround and are arranged on a side wall of the box body. Through the high-frequency loudspeakers arranged on the box body along different directions, uniformity of the play apparatus during acoustic wave propagation can be effectively increased so that the sound effect play apparatus is in a full-range encircling state. And the low-frequency loudspeaker and the high-frequency loudspeakers do not interfere with each other.

Description

technical field [0001] The invention relates to the field of loudspeakers, in particular to a playing device which is provided with a plurality of high frequency loudspeakers on the same cabinet to increase the directivity range. Background technique [0002] Generally speaking, the sound waves emitted by high-frequency speakers have obvious directivity, and the ability of the human ear to distinguish the direction of the sound source is mainly in the high-frequency range. Therefore, in the design of sound, in order to reduce the phenomenon of uneven propagation of sound waves with a high degree of directivity in the space when the high-frequency speakers emit sound waves, generally, the high-frequency speakers are installed on different cabinets. The uniformity of sound wave propagation is improved by the arrangement and distribution of each box in space to solve the problem of high frequency directivity. However, currently on the market, there is still a lack of a playbac...
