Problems solved by technology

The speaker unit is installed on the same plane as the front panel of the speaker, and several speakers share one cavity. Traditional full-range speakers are difficult to achieve a clever combination of multiple speakers. If the cavity design of multiple speakers is unreasonable, it will easily cause sound interference and Unnecessary coupling, unnecessary peaks and valleys due to box structure
The power of a traditional single speaker is too small, and when the listening area is large, a combination of multiple speakers is required, but the combination of multiple traditional speakers will greatly attenuate the high frequency, and the sound uniformity in the listening area is not good, and it is harmful to the installation Debugging is a lot of trouble

Embodiment 1

[0052] The embodiment of the present invention discloses a multi-functional combined sound box, comprising: a closed middle and high-pitch cavity body 1, and a woofer cavity body 2;

[0053] A plurality of high-pitched horns 11 are arranged side by side inside the airtight mid-tweeter cavity 1;

[0054] The end of the woofer cavity 2 is connected with a sealed back cover 21, and the woofer cavity 2 is connected to the side wall of the airtight mid-treble cavity 1;

[0055] The sealed back cover 21 and the airtight mid-treble cavity 1 can be connected through the wire 3, or an external frequency divider can be used without the wire.

[0056]In order to further optimize the above technical solution, a first screw hole 12 for connecting with the woofer cavity 2 is provided on the side wall of the airtight mid-treble cavity 1 . In the present invention, by using different cavities for the high and low speakers, and using ingenious and organic combinations, the combined sound syst...

Embodiment 2

[0063] The first woofer cavity 22 and the second woofer cavity 23 are connected to both sides of the airtight mid-treble cavity 1, and the sealing back cover 21 of the first woofer cavity 22 and the second woofer cavity 23 is airtight The middle part of the mid-treble cavity 1 is close to each other. Such as Figure 7 As shown, the first woofer cavity 22 is located on the right side of the airtight mid-treble cavity 1 , and the second woofer cavity 23 is located on the left side of the airtight mid-treble cavity 1 .

[0064] Such as Figure 9 As shown, when the application is large, a plurality of airtight mid-high-pitch chambers 1 are stacked up and down to form a linear array sound system, and the side walls of two adjacent airtight mid-high-pitch chambers 1 are connected by hanging pieces 4 .

[0065] Other technical solutions in this embodiment are the same as those in Embodiment 1, and will not be repeated here.

Embodiment 3

[0067] The first woofer cavity 22 and the second woofer cavity 23 are connected to both sides of the airtight mid-treble cavity 1, and the sealing back cover 21 of the first woofer cavity 22 and the second woofer cavity 23 is airtight The two sides of the middle and high-pitched cavity body 1 spread out. Such as Figure 11 As shown, the first woofer cavity is located on the left side of the airtight mid-tweeter cavity, and the second woofer cavity is connected to the right side of the airtight mid-tweeter cavity.

[0068] Such as Figure 13 As shown, when the application is large, multiple airtight mid-high-pitch chambers 1 are stacked up and down to form a linear array sound system, and the side walls of two adjacent airtight mid-high-pitch chambers 1 are connected by hanging pieces 4 .

[0069] Other technical solutions in this embodiment are the same as those in Embodiment 1, and will not be repeated here.

Abstract

The invention discloses a multifunctional combined sound box, which comprises a closed mid-high pitch cavity and a woofer cavity, a plurality of high-pitch horns are arranged in the closed medium-highpitch cavity side by side; the end part of the woofer cavity is connected with a sealing rear cover, and the woofer cavity is connected with the side wall of the sealed mid-high pitch cavity. According to the sound box, the tweeter and the woofer can be ingeniously combined and can be combined into sound boxes with different shapes and sound styles, and the sound box is suitable for various occasions.

Description

technical field [0001] The invention relates to the technical field of audio, and more specifically relates to a multifunctional combined sound box. Background technique [0002] Most of the traditional speakers have two or more speakers, which are combined in one box. The speaker unit is installed on the same plane as the front panel of the speaker, and several speakers share one cavity. Traditional full-range speakers are difficult to achieve a clever combination of multiple speakers. If the cavity design of multiple speakers is not reasonable, it will easily cause sound interference and Unnecessary coupling, unnecessary peaks and valleys due to the box structure. The power of a traditional single speaker is too small, and when the listening area is large, a combination of multiple speakers is required, but the combination of multiple traditional speakers will greatly attenuate the high frequency, and the sound uniformity in the listening area is not good, and it is harmf...
