Preferably, the outer side edge of the heightening ring is provided with a flanging, so that the strength of the heightening ring can be improved.

Preferably, the heightening ring, the pressing strip and the fixing frame are connected with the shell through screws uniformly arranged around the upper side edge of the shell, and the up-down lamination compaction of the heightening ring, the pressing strip and the fixing frame can be realized through the screws.

Preferably, at least one positioning lug is arranged on the upper side edge of the fixed frame, the positioning lug is matched with the insertion hole or the insertion slot on the heightening ring, and the heightening ring can be installed rapidly through the positioning lug.

Compared with the prior art, the utility model has the beneficial effects that:

simple structure adopts the split type structure that increases ring and casing, increases the ring through the change and adjusts the height of whole speaker, has also reduced the manufacturing degree of difficulty of casing, and the cost is reduced solves among the prior art the casing size of car speaker inequality, the higher problem of cost.

Detailed Description

The following description of the embodiments of the present utility model will be made clearly and completely with reference to the accompanying drawings, in which it is apparent that the embodiments described are only some embodiments of the present utility model, but not all embodiments.

As shown in fig. 1 to 4, the present utility model provides a split type woofer comprising a housing 1; a vibration plate 5 installed inside the upper side of the housing 1; a fixed frame 6 provided inside the housing 1 and located at a lower side of the vibration plate 5; a magnetic circuit assembly 4 mounted on a lower portion of the fixed frame 6 and connected to the vibration plate 5; the upper outer side edge of the fixed frame 6 is erected on the upper side edge of the shell 1, the upper side of the edge of the fixed frame 6 is provided with the heightening ring 3, the upper side edge of the vibrating plate 5 is placed on the upper side of the heightening ring 3, the upper side of the upper side edge of the vibrating plate 5 is provided with the pressing strip 2, the height of the whole loudspeaker can be adjusted by replacing the heightening ring 3, the manufacturing difficulty of the shell 1 is also reduced, and the cost is reduced.

Specifically, for speakers with similar sizes and models, the shell 1 can be designed to be of a uniform size, the height of the whole speaker can be adjusted by replacing the heightening ring 3, meanwhile, the heightening ring 3 can also play a role of pressing and fixing the fixed frame 6, and the space inside the heightening ring 3 can be used for fixing the pressing strip 2 and the vibrating plate 5, so that a complete speaker is formed.

The outer side edge of the heightening ring 3 forms a flanging, so that the strength of the heightening ring 3 can be improved, and the positions of the pressing bar 2 and the vibrating plate 5 can be limited.

In addition, the heightening ring 3, the pressing strip 2 and the fixed frame 6 are connected with the shell 1 through screws 7 uniformly arranged around the upper side edge of the shell 1, and the up-down lamination compaction of the heightening ring 3, the pressing strip 2 and the fixed frame 6 can be realized through the screws 7.

In order to quickly position the heightening ring 3, at least one positioning lug 8 is arranged on the upper side edge of the fixed frame 6, the positioning lug 8 is matched with a jack or a slot on the heightening ring 3, and the heightening ring 3 can be quickly mounted through the positioning lug 8.

It should be noted that all directional indicators (such as up, down, left, right, front, and rear are used in the embodiments of the present utility model) are merely for explaining the relative positional relationship, movement conditions, and the like between the components in a certain specific posture (as shown in the drawings), and if the specific posture is changed, the directional indicators are changed accordingly.

Furthermore, descriptions such as those referred to as "first," "second," and the like, are provided for descriptive purposes only and are not to be construed as indicating or implying a relative importance or implying an order of magnitude of the indicated technical features in the present disclosure. Thus, a feature defining "a first" or "a second" may explicitly or implicitly include at least one such feature. In the description of the present utility model, the meaning of "plurality" means at least two, for example, two, three, etc., unless specifically defined otherwise.

In the present utility model, unless specifically stated and limited otherwise, the terms "connected," "affixed," and the like are to be construed broadly, and for example, "affixed" may be a fixed connection, a removable connection, or an integral body; can be mechanically or electrically connected; either directly or indirectly, through intermediaries, or both, may be in communication with each other or in interaction with each other, unless expressly defined otherwise. The specific meaning of the above terms in the present utility model can be understood by those of ordinary skill in the art according to the specific circumstances.
