Description

Loudspeaker

【Technical field】

The utility model is related to electroacoustic conversion art, and in particular to a kind of loudspeaker.

【Background technology】

As mobile phone does thinner and thinner, the volume of loudspeaker is also less and less, in order to be designed in limited volume Bigger back cavity, the plastic casing that design embeds big steel disc is present trend.Meanwhile, with mobile phone to waterproof requirement increasingly How height, accomplishing the waterproof sealing between the preceding sound chamber of loudspeaker and rear sound chamber to mobile phone waterproof in the case of using big steel disc It is significant.

Loudspeaker in correlation technique generally sets manhole or stepped hole as grabbing glue hole, but this on big steel disc Kind is grabbed glue hole and had the following problems：

Manhole：Plastic cement good fluidity, but grab that glue intensity is very weak, during the demoulding, steel disc and plastic cement can be separated, anti-doing During the failtests of water, water will exit into interior of mobile phone at gap, not reach waterproof requirement；

Stepped hole：During injection, the easy starved of appearance causes to grab glue intensity decreases, steel disc and plastic cement can also be separated, done During the failtests of waterproof, waterproof requirement is not reached equally.

Therefore, it is necessary to provide a kind of new loudspeaker.

【Utility model content】

The purpose of this utility model, which is to provide, a kind of can reach the loudspeaker of waterproof requirement.

The technical solution of the utility model is as follows：A kind of loudspeaker, including the shell with receiving space and be contained in Loudspeaker monomer in the receiving space, the shell includes housing and firm with the reinforcement of the housing integrated injection molding Body, the reinforcement rigid body includes body and bending extension is formed and is embedded in described from the body to the receiving space direction Extension in housing, the extension surrounds the conical through-hole through the reinforcement rigid body, and the conical through-hole includes first Opening and the second opening, first opening and the described second opening are respectively arranged on the two ends of the conical through-hole, described second Opening is relative to the described first opening closer to the receiving space, and the size of the conical through-hole is open extremely along described first The direction of second opening is gradually reduced.

It is preferred that, first opening and the described second opening are in track type.

It is preferred that, the reinforcement rigid body is steel disc.

It is preferred that, the conical through-hole is by the body punch forming.

It is preferred that, the housing include with it is described reinforcement rigid body integrated injection molding the first housing and with the first shell Body encloses the second housing to form the receiving space, and the receiving space is divided into what is be in communication with the outside by the loudspeaker monomer Ante-chamber and the back cavity relative with the ante-chamber, the conical through-hole are arranged at the intersection of the ante-chamber and the back cavity.

Compared with correlation technique, the beneficial effect for the loudspeaker that the utility model is provided is：

By setting conical through-hole on the reinforcement rigid body, plastic cement good fluidity when being not only molded does not have starved Problem, and when the demoulding, because the conical through-hole is involved to plastic cement, plastic cement will not be separated with the reinforcement rigid body； The sealing property and reliability of this structure can all be better than common manhole or step pore structure simultaneously, can reach anti- The design requirement of water.

【Brief description of the drawings】

The exploded view of one preferred embodiment of the loudspeaker that Fig. 1 provides for the utility model；

Fig. 2 is the structural representation after loudspeaker shown in Fig. 1 is assembled；

Fig. 3 is sectional view of the loudspeaker along A-A directions shown in Fig. 2.

【Embodiment】

Below in conjunction with the accompanying drawing in the utility model embodiment, the technical scheme in the utility model embodiment is carried out Clearly and completely describe, it is clear that described embodiment is only a part of embodiment of the utility model, rather than whole Embodiment.Based on the embodiment in the utility model, those of ordinary skill in the art are not under the premise of creative work is made The every other embodiment obtained, belongs to the scope of the utility model protection.

Fig. 1, Fig. 2 Fig. 3 are referred to, the loudspeaker 100 includes the shell 1 with receiving space and is contained in the receipts Hold the loudspeaker monomer 3 in space.The loudspeaker monomer 3 by the receiving space be divided into ante-chamber 1A and with the ante-chamber 1A phases To back cavity 1B, the ante-chamber 1A is in communication with the outside, and the back cavity 1B is connected with the inside of loudspeaker monomer 3.

The shell 1 includes housing 11 and the reinforcement rigid body 13 with the integrated injection molding of housing 11.

The housing 11 is plastic casing, and it includes the first housing 111 with the reinforcement integrated injection molding of rigid body 13 And the second housing 113 to form the receiving space is enclosed with first housing 111.

The rigidity that the reinforcement rigid body 13 is used to strengthen the shell 1 allows to ensureing the rigidity of the shell 1 Under the premise of reduce its thickness.

The reinforcement rigid body 13 includes body 131 and extension is bent from the body 131 to the receiving space direction Formed and be embedded in bending part 132 and extension 133 in first housing 111.

The body 131 is included away from the lower surface 1311 of the receiving space and relative with the lower surface 1311 upper Surface 1313.

The extension 133 surrounds the conical through-hole 134 through the reinforcement rigid body 13.

The conical through-hole 134 includes the first opening 135 and the second opening 137, first opening 135 and described second Opening 137 is respectively arranged on the two ends of the conical through-hole 134, and second opening 137 is relative to the described first opening 135 more Close to the receiving space.Wherein, first opening 135 is located on the lower surface 1311.

The conical through-hole 134 is arranged at the ante-chamber 1A and the back cavity 1B intersection, and the conical through-hole 134 Size along described first opening 135 to described second opening 137 direction be gradually reduced.

In the present embodiment, first opening 135 and second opening 137 are in track type.

Conical through-hole 134 by set the bending part 132 and the conical through-hole 134 ensure it is described reinforcement rigid body 13 with First housing 111 is stripped, and plastic cement will not be separated with the reinforcement rigid body 13, and the sealing property of this structure and can By property.

In order that obtaining the conical through-hole 134 by the punch forming of body 131.It is preferred that, the reinforcement rigid body 13 is Steel disc.

The beneficial effect for the loudspeaker that the utility model is provided is：

By setting conical through-hole 134 on the reinforcement rigid body 13, plastic cement good fluidity when being not only molded does not have scarce The problem of glue, and when the demoulding, because the conical through-hole 134 is involved to plastic cement, plastic cement will not strengthen firm with described Body 13 is separated；The sealing property and reliability of this structure can all be better than common manhole or step pore structure simultaneously, The design requirement of waterproof can be reached.

Above-described is only embodiment of the present utility model, it should be noted here that for the ordinary skill of this area For personnel, on the premise of the utility model creation design is not departed from, improvement can also be made, but these belong to this practicality New protection domain.
