SUMMERY OF THE UTILITY MODEL

To the defect among the prior art, the utility model provides a bluetooth headset shell both can install the equipment that the moving iron was applicable to moving iron tone quality earphone, also can not install the equipment that the moving iron was applicable to ordinary tone quality earphone.

The above technical purpose of the present invention can be achieved by the following technical solutions: the utility model provides a bluetooth headset shell, includes preceding shell and backshell, preceding shell has a sound pipe the sound pipe of going out of preceding shell is intraductal from the back cartridge to the front and is had moving iron support, the sound pipe is stretched out to the front end that moves iron support.

The utility model inserts the moving iron bracket into the sound outlet pipe of the front shell from back to front instead of directly lengthening the sound outlet pipe, when the moving iron is required to be installed to produce the moving iron tone quality earphone, the moving iron is only required to be inserted into the moving iron bracket from back to front; when the movable iron is not required to be installed to produce the common tone quality earphone, only the movable iron support is required to be removed; thereby a bluetooth headset shell that can general two kinds of tone quality is provided, avoids the respective die sinking production of bluetooth headset shell of two kinds of tone qualities, is favorable to manufacturing cost's control, also is favorable to the unity of producer's product appearance.

The sound outlet pipe is provided with a large-diameter hole, a tapered hole, a middle-diameter hole and a small-diameter hole which are coaxially communicated from back to front, the front end of the large-diameter hole is in equal-diameter transition with the rear end of the tapered hole, the front end of the tapered hole is in equal-diameter transition with the rear end of the middle-diameter hole, and the front end of the middle-diameter hole is in step surface transition with the rear end of the small-diameter hole; the outer wall of the moving iron bracket is matched with the large-diameter hole, the conical hole, the middle-diameter hole and the small-diameter hole of the sound outlet pipe. The matching of the sound outlet pipe and the moving iron support is stable and reliable, the structure is simple, and the production is easy.

The moving iron bracket is provided with a large cylindrical hole, a small cylindrical hole and a mounting hole which are communicated from back to front. The large cylindrical hole in the moving iron support can be used for inserting the horn, the mounting hole can be used for mounting the moving iron, so that the horn and the moving iron can be stably and reliably mounted, and the moving iron support is simple in structure and easy to produce.

The aperture of the large cylindrical hole is equal to that of the diameter hole in the sound outlet pipe. When the common tone quality earphone without the moving iron is produced, the moving iron bracket is removed, and the loudspeaker can be directly inserted into the middle diameter hole of the sound outlet pipe, so that the loudspeaker is stably and reliably installed.

Has the advantages that: the utility model discloses a shell goes out sound intraductal cartridge from back to front and moves indisputable support to provide one kind can general two kinds of tone quality bluetooth headset shell, avoid the bluetooth headset shell of two kinds of tone quality die sinking production separately, be favorable to manufacturing cost's control, also be favorable to the unification of producer product appearance, have design ingenious, simple structure, production is easy, low in production cost etc. characteristics.

Detailed Description

Embodiments of the present invention will be described in detail below with reference to the accompanying drawings. The following examples are only for illustrating the technical solutions of the present invention more clearly, and therefore are only examples, and the protection scope of the present invention is not limited thereby.

It is to be noted that unless otherwise specified, technical or scientific terms used herein shall have the ordinary meaning as understood by those skilled in the art to which the present invention belongs.

As shown in fig. 1, the present embodiment provides a bluetooth headset case, which includes a front case 2 and a rear case 1 fixedly connected together to form an accommodating chamber, where the front case 2 has a sound outlet pipe 3, a moving iron bracket 4 is inserted into the sound outlet pipe 3 of the front case 2 from back to front, and the front end of the moving iron bracket 4 extends out of the sound outlet pipe 3.
