Description
[technical field]
The present invention relates to a kind of acoustical generator, relate in particular to a kind of minitype acoustic generator that is applied on the portable consumer electronic products such as mobile phone.
[background technology]
Minitype acoustic generator is widely used in the portable electronic equipments such as mobile phone, notebook computer, hearing aids.Along with fast development, the people of these portable electronic equipments are more and more stronger to its Functional Requirement, the mini-sound device that is applied thereon is corresponding development rapidly also.
The minitype acoustic generator of correlation technique comprises pedestal, the upper cover that is connected with pedestal, and described pedestal and upper cover form host cavity jointly, also are provided with the sounding monomer in described host cavity.Also be provided with the welding muscle on described pedestal, in order to regulate the whole height of minitype acoustic generator.Be electrically connected in order to coordinate with other electronic product to form, the sounding monomer that the minitype acoustic generator of correlation technique also is provided with in host cavity draws the metal pin of receiving outside host cavity, metal pin is provided with fixed part and the connecting portion that is extended by fixed part and the contact site that is extended by connecting portion, described welding muscle is required to be the processing of stepping down of fixed part that metal pin is positioned at host cavity, thereby make between welding muscle and fixed part, has gap.Because the welding muscle is that plastic material is made, the welded seal effect that causes welding between muscle and fixed part is bad.Therefore, the minitype acoustic generator of correlation technique arranges glue at the welding muscle place of stepping down, with the sealing between the fixed part of glue realization welding muscle and metal pin.
Yet, because glue is not easy to fix, easily overflow and also pollute contact site to the contact site of metal pin, if loose contact when contact site may be caused the product of correlation technique and other electronic product to be used in conjunction with by the glue pollution affects the performance of the product of correlation technique.
[summary of the invention]
The technical problem that the present invention need solve is to provide the sealing between a kind of fixed part that can realize welding muscle and metal pin, and can not pollute the minitype acoustic generator of connecting portion.
According to above-mentioned technical problem, designed a kind of minitype acoustic generator, its objective is such realization: a kind of minitype acoustic generator, it comprises pedestal and the upper cover that is connected with described pedestal, the metal pin that described pedestal is provided with the welding muscle and through described welding muscle bottom, extends.Described metal pin is provided with the fixed part that is fixed on described pedestal, the connecting portion that is extended by fixed part and the contact site that is extended by connecting portion.The junction of described connecting portion and described contact site is provided with faying face.Wherein, described upper cover also is provided with the baffle plate that is oppositely arranged with described welding muscle, described baffle plate between described faying face and described welding muscle and with described connecting portion or described fixed part butt, described baffle plate and described welding muscle form accepting groove jointly.
The present invention also provides a kind of minitype acoustic generator, and it comprises pedestal and the upper cover that is connected with described pedestal, the metal pin that described pedestal is provided with the welding muscle and through described welding muscle bottom, extends.Described metal pin is provided with the fixed part that is fixed on described pedestal, the connecting portion that is extended by fixed part and the contact site that is extended by connecting portion.The junction of described connecting portion and described contact site is provided with faying face.Wherein, also be provided with the baffle plate that is oppositely arranged with described welding muscle on described pedestal, described baffle plate is between described faying face and described welding muscle, and described baffle plate and described welding muscle form accepting groove jointly.
Preferably, described baffle plate and described upper cover butt.
Minitype acoustic generator of the present invention has been realized the sealing between welding muscle and metal pin and can not have been polluteed the connecting portion of metal pin.

Fig. 1 is the part-structure exploded view of minitype acoustic generator of the present invention.
Fig. 2 is the three-dimensional structure diagram of the upper cover of minitype acoustic generator of the present invention.
Fig. 3 is the three-dimensional structure diagram of minitype acoustic generator of the present invention.
Fig. 4 is the part-structure cut-away view along A-A line in Fig. 2.Wherein, glue is filled out and is located in accepting groove.
[embodiment]
The invention will be further described below in conjunction with drawings and embodiments.
As Figure 1-4, a kind of minitype acoustic generator 1, it comprises pedestal 3 and the upper cover 2 that is connected with pedestal 3.The metal pin 9 that pedestal 3 is provided with welding muscle 31 and through welding muscle 31 bottoms, extends.Metal pin 9 is provided with the fixed part 91 that is fixed on pedestal 3, the connecting portion 92 that is extended by fixed part 91 and the contact site 93 that is extended by connecting portion 92, and contact site 93 external worlds communicate, and connecting portion 92 is provided with faying face 5 with the junction of contact site 93.Wherein, upper cover 2 also is provided with and the baffle plate 8 that welds muscle 31 and be oppositely arranged, baffle plate 8 between faying face 5 and welding muscle 31 and with connecting portion 92 or fixed part 91 butts, baffle plate 8 and the common accepting groove 7 that forms of welding muscle 31.Because metal pin 9 is extended through welding muscle 31 bottoms, welding muscle 31 needs there is gap 6 in metal pin 9 processing of stepping down thereby make to weld between muscle 31 and metal pin 9.
In order to guarantee that minitype acoustic generator 1 has better audio, be required to be sealing state in its sounding cavity,, owing to having gap 6 between welding muscle 31 and metal pin 9, need gap 6 sealings, the present invention uses glue 4 sealing off gap 6.Concrete, glue 4 is arranged in baffle plate 8 and the accepting groove 7 of welding between muscle 31, because glue 4 tool toughness, it can flow to gap 6 and gap 6 is sealed, simultaneously because the existence of baffle plate 8 is arranged, can block glue 4, although also there is gap 6 in baffle plate 8 with metal pin 9 butt places, but because gap 6 is little, when glue 4 is not enough to overflow to the contact site 93 of metal pin 9 just to solidify, therefore can not pollute contact site 93, come in contact bad problem while having avoided minitype acoustic generator of the present invention and other products to be used in conjunction with.
The present invention also provides a kind of minitype acoustic generator, it is substantially identical with above-mentioned minitype acoustic generator 1, different is: plate washer 8 is not arranged on upper cover 2, but pedestal 3 is provided with and the baffle plate 8 that welds muscle 31 and be oppositely arranged, and baffle plate 8 is between faying face 5 and welding muscle 31.More excellent, baffle plate 8 and upper cover 2 butts.
Compare with correlation technique, the present invention is because being provided with baffle plate, and it forms accepting groove with the welding muscle, and in the time of in glue is arranged on accepting groove, glue, because of tool toughness, does not flow in gap and solidifies, with gap sealing.And because the effect of baffle plate, glue but can not pollute the connecting portion of metal pin, thereby guaranteed the satisfactory electrical conductivity when metal pin is connected with external circuitry, not there will be the problem because of the contaminated loose contact that occurs of the connecting portion of metal pin, and then improved the performance of minitype acoustic generator of the present invention.
Above-described is only embodiments of the present invention, at this, should be pointed out that for the person of ordinary skill of the art, without departing from the concept of the premise of the invention, can also make improvement, but these all belongs to protection scope of the present invention.
