A kind of improved earphone horn

Technical field:

The utility model relates to the ear speaker device technical field, refers in particular to a kind of improved earphone horn.

Background technology:

Existing earphone generally is made up of horn base of wearing frame and being installed in its two ends etc.Wherein, the earphone that one class scalable horn base height is arranged, it mainly comprises: wear frame, be installed in the box body of wearing the frame two ends, be installed in adjusting bracket on the box body, be installed on horn base on the adjusting bracket, be installed on the loudspeaker in the horn base, box body be by screw with wear frame and fixedly connected, adjusting bracket passes box body and slidably regulates; Horn base generally is made up of lid and base, loudspeaker are directly to cohere on the base medial surface by glue, adopt this mode of cohering to have the following disadvantages: at first, in the process of cohering, because glue quantity is not easy control, thereby can cause too much glue to flow on the interior vibrating reed of loudspeaker, therefore cause earphone distortion and fraction defective height.Secondly, loudspeaker come unstuck easily, therefore cause loudspeaker to break away from base.Once more, loudspeaker are changed inconvenient.

The utility model content:

The purpose of this utility model is to overcome the weak point of existing product, and a kind of improved earphone horn is provided.

The utility model realizes that the technical scheme that its purpose adopts is: this improved earphone horn comprises: horn base, be installed on the loudspeaker in the horn base, described loudspeaker form a plurality of flanges, have connecting hole on the flange, the horn base inwall forms respectively the connecting portion that is complementary with connecting hole, and being connected by connecting hole and connecting portion makes loudspeaker be removably connected on the horn base inwall.

Described horn base is to be combined by lid and base, and connecting portion takes shape on the base inner wall, and being connected by connecting hole and connecting portion makes loudspeaker be removably connected on the base inner wall.

Described flange takes shape on the external diameter of loudspeaker.

A described connecting hole part is a through hole, and another part is a hole clipping, and forms connecting portion in the position of the inner corresponding through hole of described base, and this connecting portion is the self tapping joint pin; The position of the inner corresponding hole clipping of described base forms the connecting portion that embeds in the hole clipping, and this connecting portion is the card post; The card post embeds in the hole clipping, and by tapping screw loudspeaker is removably connected on the base inner wall.

Or described connecting hole all is a through hole, and forms the self tapping joint pin in the position of the inner corresponding through hole of described base, by tapping screw loudspeaker is removably connected on the base inner wall.

Described base is coated with a sponges cover.

The utility model the utlity model has following advantage after adopting said structure: the utility model can promote greatly product operating efficiency, simplify technology, save cost, be convenient for changing, strengthen quality, it is more firm that loudspeaker are connected with base.

Description of drawings:

Fig. 1 is an exploded perspective view of the present utility model among the embodiment one;

Fig. 2 is an exploded perspective view of the present utility model among the embodiment two.

Embodiment:

Below in conjunction with specific embodiments and the drawings the utility model is further specified.

Embodiment one

As shown in Figure 1, the utility model is installed on the earphone of scalable horn base height, and this earphone mainly comprises in the present embodiment: wear frame 5, be installed in the box body 6 of wearing frame 5 two ends, be installed in adjusting bracket 7 on the box body 6, be installed on horn base 1 on the adjusting bracket 7, be installed on the loudspeaker 2 in the horn base 1.

Particularly: above-mentioned box body 6 be by screw with wear frame 5 and fixedly connected, adjusting bracket 7 passes box body 6 and slidably regulates.Above-mentioned horn base 1 is to be combined by lid 11 and base 12.Form three flanges 21 on above-mentioned loudspeaker 2 external diameters, have three connecting holes on the flange 21, one of them connecting hole is a through hole 211, remain two connecting holes and be respectively hole clipping 212, and form a connecting portion in the position of described base 12 inner corresponding through holes 211, this connecting portion is a self tapping joint pin 121.The position of above-mentioned base 12 inner corresponding two hole clippings 212 forms two connecting portions that embed in the hole clipping 212, these two connecting portions are respectively card post 122, two card posts 122 embed respectively in two hole clippings 212, and by a tapping screw loudspeaker 2 are removably connected on base 12 inwalls.

The above-mentioned frame 5 of wearing comprises: head hoop shell fragment 51, be sheathed on the soft plastic cover 52 of head hoop shell fragment 51 peripheries, can strengthen the comfortableness that the user uses by soft plastic cover 52, and can protect head hoop shell fragment 51 and play decoration function.

Be coated with a sponges cover 4 in base 12, can strengthen the comfortableness that the user uses by this sponges cover 4.
