Description

An external speaker inverting tube

technical field

The utility model relates to the field of sound boxes, in particular to an external sound box inverting tube.

Background technique

At present, the common speakers on the market are mainly sealed structures without inverted tubes. After this type of speaker is played, the generated sound spreads around, with a wide spread and short distance. The sound intensity heard by the human ear is low, and the sound has the defect of non-directional spread. Now, there is a kind of speaker with inverted tube, but it is installed inside the speaker, which takes up the volume of the speaker.

Utility model content

In view of the above problems, the purpose of the present invention is to provide an external speaker inverter tube with good sound effect and simple structure, and does not occupy the volume of the speaker body.

In order to achieve the above-mentioned purpose, the utility model provides an external speaker inverting tube, wherein the bottom of the speaker body is provided with a semi-enclosed seat that forms a cavity with the bottom of the speaker body, and a bottom surface of the semi-enclosed seat is provided. There are support feet on it. The semi-closed seat includes a left connecting block and a right connecting block connected with the two sides of the bottom of the speaker body, a rear connecting block connected on the rear side of the bottom of the speaker The bottom panel to which the block, right connection block, and rear connection block are attached.

In some embodiments, a front opening communicated with the inner cavity of the semi-closed seat is provided between the bottom panel and the bottom of the front of the speaker body.

In some embodiments, the bottom panel located at the front opening is provided with a protrusion which is connected to the bottom of the sound box and divides the front opening into two openings.

In some embodiments, a left opening communicated with the inner cavity of the semi-closed seat is provided between the bottom panel and the bottom of the left side of the speaker body.

In some embodiments, a right opening communicated with the inner cavity of the semi-closed seat is provided between the bottom panel and the bottom of the right side of the speaker body.

In some embodiments, a rear opening communicated with the inner cavity of the semi-closed seat is provided between the bottom panel and the bottom of the rear side of the speaker body.

In some embodiments, the bottom panel is an arcuate panel.

In some embodiments, the bottom panel is an arched panel.

In some embodiments, the support feet are support pads.

The beneficial effect of the utility model is that the sound effect is good and the structure is simple. Since the woofer on the speaker body is installed in the bottom of the speaker body, and the semi-enclosed seat is also installed at the bottom of the speaker body, the semi-enclosed seat is mainly used to invert the sound effect of the subwoofer, which solves the problem of the surrounding transmission in the prior art. , the transmission range is wide, the distance is short, the sound intensity heard by the human ear is low, and the sound has the defect of non-directional transmission, so the sound effect produced is more, and it spreads farther. In addition, the structure of the semi-closed seat is relatively simple, mainly composed of a semi-closed arched cavity, and the opening of this cavity is in the same direction as the front of the speaker body, which achieves the effect of simple structure. And because the semi-enclosed seat is installed outside the speaker body, it does not affect the internal volume occupation of the speaker body.

Detailed ways

The utility model will be described in further detail below in conjunction with the accompanying drawings.

As shown in Figures 1-4, an external speaker inverter tube includes a semi-closed seat 2 formed on the bottom of the speaker body 1 and the bottom of the speaker body 1 to form a cavity, and a bottom surface of the semi-closed seat 2 There are supporting feet 3 on it. The semi-closed seat 2 includes a left connecting block 21 and a right connecting block 22 connected with both sides of the bottom of the speaker body 1 , a rear connecting block 23 connected on the rear side of the bottom of the speaker body 1 , and the bottom of the speaker body 1 . There are bottom panels 24 respectively connected with the left connecting block 21 , the right connecting block 22 and the rear connecting block 23 . A front opening 25 communicating with the inner cavity of the semi-closed seat 2 is provided between the bottom panel 24 and the bottom of the front of the speaker body 1 . On the bottom panel 24 of the front opening 25, there is provided a bump 26 which is connected to the bottom of the sound box and divides the front opening 25 into two openings. Between the bottom panel 24 and the bottom of the left side of the speaker body 1 is a left opening communicating with the inner cavity of the semi-closed seat 2 . A right opening communicated with the inner cavity of the semi-closed seat 2 is provided between the bottom panel 24 and the bottom of the right side of the speaker body 1 . Between the bottom panel 24 and the bottom of the rear side of the speaker body 1 is a rear opening that communicates with the inner cavity of the semi-closed seat 2 . The bottom panel 24 is an arc panel. Bottom panel 24 is an arched panel. The supporting foot 3 is a supporting rubber pad.

In application, the woofer on the speaker body 1 is installed in the bottom of the speaker body 1, and the semi-closed seat 2 is also installed at the bottom of the speaker body 1, so the semi-closed seat 2 is mainly for the sound effect of the woofer 20. It solves the defects in the prior art that the sound is propagated around, the propagation range is wide, the distance is short, the sound intensity heard by the human ear is low, and the sound has non-directional propagation, so the sound effect produced is more and the propagation is farther. In addition, the structure of the semi-closed seat 2 is relatively simple, mainly composed of a semi-closed arched cavity, and the opening of the cavity is in the same direction as the front of the speaker body 1, which achieves the effect of simple structure.

The above are only some embodiments of the present invention. For those of ordinary skill in the art, without departing from the inventive concept of the present invention, several modifications and improvements can be made, which all belong to the protection scope of the present invention.
