Description

a speaker

[Technical Field]

The present invention relates to the field of household appliances, and more particularly to a speaker. 【Background technique】

I have designed a speaker comprising a housing, a louver mounted in the housing, an opening for sound emission disposed on the housing, and a horn cover for closing the opening, the horn cover is provided with a pin The shaft and the end of the horn cover are fixed on the casing through the pin shaft, and the horn cover can be opened by rotating the pin shaft, so that the speaker cover can close the horn sound hole when the speaker is not used, and the horn cover can be opened when used, thereby preventing dust Or other debris falling into it. This program is not public. However, since one end of the horn is fixed to the casing by the pin, the horn directly contacts the casing and closes the opening, so that friction is constantly generated between the horn and the casing, which may damage the surface of the casing.

[Summary of the Invention]

The technical problem to be solved by the present invention is to provide a speaker which has a better sealing effect on the opening of the Rabal sound.

The object of the present invention is achieved by the following technical solutions: a sound box comprising a housing, an opening disposed on the housing for sound emission, and a speaker cover fixed at one end to the housing for closing the opening, The speaker also includes a pad disposed between the housing and the horn cover.

Preferably, the pad is fixed on the housing, and the pad is provided with a through hole, and the through hole is disposed in the opening. The pad is fixed on the housing, and when the speaker cover is closed, it contacts the pad, and the pad prevents the speaker cover from contacting the housing and wears the housing; and the through hole is provided with a through hole to make the speaker sound .

Preferably, the pad is provided with a fixing post, and the housing is provided with a slot for placing the fixing post. The fixing post on the pad is inserted into the slot, so that the pad is fixed on the housing, and the pad is conveniently inserted into the slot through the fixing post. Preferably, the pad is provided with a groove, and the fixing column is located in the groove. Setting the groove saves material and reduces the weight of the pad.

Preferably, the edge of the pad extends downwardly and the extended portion forms the groove. A through hole is formed in the middle of the pad, the pad is annular, and the edge of the pad extends downward, and a groove is formed between the edges, so that the edge is tightly connected to the case when the pad is fixed with the case.

Preferably, the extending portion has a curvature, and the edge of the rib cover has a downward convex edge corresponding to the outer edge of the pad, and the convex edge cooperates with the edge of the pad. The convex edge on the speaker cover is arranged on the edge of the pad, and the convex edge is closely matched with the edge of the pad when the bar is closed, so that the sealing effect of the bar is better.

Preferably, the height of the convex edge is less than the thickness of the mat. Therefore, it is ensured that the speaker cover does not contact the housing, and the speaker cover is prevented from wearing the housing.

Preferably, the fixing post is provided with a rounded corner. This facilitates the insertion of the mounting post into the slot, thereby facilitating the mounting of the pad to the housing.

Preferably, the inner side wall of the slot is provided with a bump. When the mounting post is inserted into the slot, the tabs compress the mounting post, allowing the mounting post to be more securely secured within the slot.

Preferably, the bumps are at least two and are arranged at intervals. A plurality of bumps have a better fixing effect on the fixing post.

In the present invention, since the speaker is provided with a pad placed between the speaker cover and the casing, the direct contact between the speaker cover and the casing is avoided; the pad can be made of a soft material or directly fixed to the casing. Therefore, the speaker cover contacts the pad at the time of opening and closing, thereby preventing the casing from being worn; and the speaker cover is mated with the pad, and the pad and the housing are matched, so that the sealing effect of the speaker cover is better, the speaker cover and the speaker cover The padding is also convenient to open the bar.
