Hereinafter, a front cover detachable speaker according to the present invention will be described in more detail with reference to an embodiment and the accompanying drawings.

As shown in fig. 1 to 3, in the present embodiment, a speaker with a detachable bezel is proposed, which includes a bezel 10 and a bracket 80 disposed below the bezel 10, a U-cup 70 penetrates into a cavity of the bracket 80 from bottom to top, and a diaphragm 20, a voice coil 30, a washer 50 and a magnet 60 are sequentially disposed from top to bottom in a space formed by the bezel 10, the bracket 80 and the U-cup 70.

In this embodiment, the front cover 10 is detachably sleeved on the bracket 80, the side wall of the front cover 10 is in transition fit with the outer wall of the bracket 80, the height of the side wall of the front cover 10 is at least two thirds of the height of the bracket 80, the lower end portion of the bracket 80 extends out of the side wall of the front cover 10, and the outer diameter of the front cover 10 is larger than the outer diameter of the bracket 80. In this embodiment, the front cover 10 covers almost the entire bracket 80, but a part of the side wall of the bracket 80 near the bottom extends out of the front cover 10 so that the user can detach and attach the two.

The diaphragm 20 is provided with a copper ring 201 at the outer periphery, the copper ring 201 is arranged on the top surface of the bracket 80 by means of glue adhesion, and the diaphragm 20 is located inside the space formed by the bracket and the front cover 10.

Specifically, the outer periphery of the sidewall of the bracket 80 extends upward and protrudes beyond the bracket top 804 to form a ring of convex ring 802, as shown in fig. 3, the copper ring 201 is fixed by gluing and contacting the convex ring 802 and the bracket top 804. In this embodiment, the copper ring 201 is located between the support 80 and the front cover 10 and limited by the two, when the front cover 10 covers the support 80, the front cover 10 also plays a certain protection role on the diaphragm 20, and the traditional arrangement mode is to directly set or expose the diaphragm outside the front cover, and a protection cover needs to be additionally set to prevent the diaphragm 20 from being damaged in transportation.

Because protecgulum 10 can be followed support 80 and demolishd, consequently the miniature loudspeaker that this embodiment provided can realize two kinds of different structures, one kind is the loudspeaker after the protecgulum demolishs, and another kind is the loudspeaker that the protecgulum did not demolish, corresponds two kinds of different external diameter sizes respectively, can select according to service environment's specific need, and the switching of two kinds of structures is very convenient.

As shown in fig. 2, the two welding members 40 are embedded in the bracket 80, each welding member 80 includes a soldering tab portion, a connecting portion, and a bottom conductive portion (not shown), wherein the soldering tab portion and the bottom conductive portion are horizontally disposed, the soldering tab portion and the bottom conductive portion extend in opposite directions, the connecting portion is step-shaped, and two ends of the connecting portion are respectively connected to the soldering tab portion and the bottom conductive portion. The welding sheet part, the connecting part and the bottom conductive part are integrally formed.

Further, with reference to fig. 2 and 3, an opening 803 through which the voice coil passes is formed on a top surface 804 of the support 80, the voice coil 30 is connected to a lower surface of the diaphragm 20 and is disposed concentrically with the diaphragm 20, and a portion of the voice coil passes through the opening 803, the washer 50 and the magnet 60 are disposed coaxially with the voice coil 30, and a predetermined distance exists between the voice coil 30 and the washer 50 and the magnet 60.

Further, with continued reference to fig. 2 and 3, the U-cup 70 includes a bottom (not labeled) that matches the shape of the bottom of the cavity of the holder 80, and a columnar structure (not labeled) that extends from the center of the bottom toward the cavity of the holder 80. As shown in fig. 3, the washer 50 and the magnet 60 enter the bracket 80 from the bottom cavity of the bracket 80, the outer side walls of the washer 50 and the magnet 60 are abutted against the inner side wall of the bracket 80, the upper end surface of the washer 50 is abutted against the lower end surface of the top 804 of the bracket 80, and the lower end surface of the magnet 60 is abutted against the upper end surface of the bottom of the U-cup 70, so that the washer 50 and the magnet 60 are limited between the bracket 80 and the U-cup 70.

As shown in fig. 3, a preset gap exists between the inner side walls of the washer 50 and the magnet 60 and the columnar structure, the voice coil 30 is partially located between the gaps, and a preset distance exists between the voice coil 30 and the inner side walls of the washer 50, the inner side walls of the magnet 60 and the outer side walls of the columnar structure, so that an external magnetic structure is formed. By limiting the washer 50 and the magnet 60 between the bracket 80 and the U-shaped cup 70, the magnet 60 is prevented from moving, and only the voice coil 30 moves relative to the magnet 60 when the voice coil is powered on for use, so that the quality of the tone quality is ensured.

Furthermore, two welding gaps 801 are formed in the convex ring 802, the two welding gaps 801 are communicated with the opening 803, the bracket top surface 804 is divided into a first bracket top surface (major arc region) and a second bracket top surface (minor arc region) by the two welding gaps 801 and the opening 803, and the second bracket top surface is located between the two welding gaps 801 and is separated from the first bracket top surface. In the present embodiment, the tab portion is disposed at the soldering indentation 801, and the bottom conductive portion is exposed at the bottom of the stand 80.

The detachable horn of protecgulum that provides in this embodiment because the relative support of protecgulum can carry out the split for this detachable horn of protecgulum can have two kinds of different external diameter sizes, can use in the service environment of two kinds at least differences, realizes the dual-purpose function of a product, need not design two sets of independent moulds respectively to two kinds of different external diameter sizes, has saved production and use cost like this simultaneously.

In addition, the front cover is sleeved on the outer wall of the support, and the front cover and the support are in transition fit, so that the front cover can be in relatively static connection when sleeved on the support, looseness is not easy to occur, and meanwhile, the front cover is easy to disassemble and assemble.
