Problems solved by technology

Therefore, the volume occupied by the speaker is relatively large, and it is not convenient enough.
If two sets of speaker units are integrated on one box, then the two sets of speaker units will have a very large vibration inertia when they are in use, resulting in very serious sound coloration, and the sound quality of the entire speaker is very bad.
If two channels are designed in one speaker, usually the mid-bass speaker and the tweeter are placed in the same direction in this design. Considering the directivity of the treble, the speaker will face the front, so that it is difficult for the mid-bass speaker to achieve a mirror image. setting, so that the vibration inertia of the bass needs to be offset by the weight of the cabinet, the weight of the speaker becomes very large

Embodiment 1

[0027] refer to figure 1 and figure 2 , the present invention provides a stereophonic box, comprising: a box body 1; two groups of sounding units 2 are arranged on the surface of the box body 1, corresponding to the left channel and the right channel; each group of sounding units 2 includes a Bass unit 21 and a tweeter unit 22;

[0028] The woofers 21 of the two groups of sounding units 2 are arranged as mirror images to offset the vibration inertia; each woofer 21 is provided with the tweeter 22 outside.

[0029] In the above-mentioned stereo sound box, the two woofers 21 on the box body are arranged as mirror images, so that the vibration inertia generated by the two woofers 21 can cancel each other out, so that the high fidelity of the bass can be maintained when the speaker shell is light. Therefore, the box body 1 in this embodiment can be manufactured by blow-molding integral molding process, and the shape of the box body 1 is a pressure vessel, specifically spherical...

Embodiment 2

[0035] The difference between this embodiment and Embodiment 1 is that: two tweeters 22 are arranged on the outside of each bass unit 21 ; the tweeters 22 are arranged on the left and right sides of the bass unit 21 . Therefore, the sound box has a 360° listening effect in the horizontal direction (there are balanced sound effects in the left, right, front and back of the sound box).

Embodiment 3

[0037] refer to image 3 and Figure 4 The difference between this embodiment and Embodiment 1 is that four tweeters 22 are arranged outside each bass unit 21; Therefore, the sound box has a three-dimensional listening effect (there are balanced sound effects at the top, bottom, left, and right sides of the sound box).

Abstract

The invention provides a stereophonic sound box. The stereophonic sound box comprises a box body; two groups of sound production units are arranged on the surface of the box body and are correspondingly a left sound channel and a right sound channel; each group of sounding units comprises a bass unit and at least one treble unit; the bass units of the two groups of sounding units are arranged in amirror image manner so as to mutually counteract the vibration inertia; and the high pitch unit is arranged on the outer side of each low pitch unit. According to the stereo sound box, high fidelityof bass can be maintained under the condition that the box body is light.

Description

technical field [0001] The invention relates to a loudspeaker, in particular to a stereo sound box. Background technique [0002] A traditional stereo system generally requires two independent speakers to be combined to form left and right channels. Therefore, the volume occupied by the speaker is relatively large, and it is not convenient enough. If two sets of speaker units are integrated on one box, then the two sets of speaker units will have a very large vibration inertia when they are in use, resulting in very serious sound coloration, and the sound quality of the entire speaker will be very bad. If two channels are designed in one speaker, usually this design will place the mid-bass speaker and tweeter in the same direction. Considering the directivity of the treble, the speaker will face the front, so that it is difficult for the mid-bass speaker to achieve a mirror image. Setting, so that the vibration inertia of the bass needs to be offset by the weight of the ca...
