[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 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 also corresponding development apace of the mini-sound device that is applied thereon.
The minitype acoustic generator of correlation technique comprises pedestal, the loam cake that is connected with pedestal, and described pedestal and loam cake form host cavity jointly, also are provided with the sounding monomer in the described host cavity.Also be provided with the welding muscle on the described pedestal, in order to regulate the whole height of minitype acoustic generator.Be electrically connected in order to cooperate 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 the host cavity, metal pin is provided with fixed part and connecting portion that is extended by fixed part and the contact site that is extended by connecting portion, described welding muscle then is required to be the processing of stepping down of fixed part that metal pin is positioned at host cavity, thereby makes and have the slit between welding muscle and the fixed part.Because the welding muscle is that plastic material is made, the welded seal effect that causes welding between muscle and the fixed part is bad.Therefore, the minitype acoustic generator of correlation technique is provided with 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, overflow easily to the contact site of metal pin and pollute contact site, if loose contact when contact site may be caused the product of correlation technique and other electronic product to be used by the glue pollution, influence the performance of the product of correlation technique.
[summary of the invention]
The technical problem that the present invention need solve provides 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 loam cake that is connected with described pedestal, the metal pin that described pedestal is provided with the welding muscle and extends through described welding muscle bottom.Described metal pin is provided with the fixed part that is fixed on the 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 loam cake 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 loam cake that is connected with described pedestal, the metal pin that described pedestal is provided with the welding muscle and extends through described welding muscle bottom.Described metal pin is provided with the fixed part that is fixed on the 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 the 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 loam cake butt.
Minitype acoustic generator of the present invention has been realized the sealing between welding muscle and the metal pin and can not have been polluteed the connecting portion of metal pin.
[description of drawings]
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 loam cake 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 among Fig. 2.Wherein, glue has been filled out and has been located in the accepting groove.
[embodiment]
The invention will be further described below in conjunction with drawings and embodiments.
Shown in Fig. 1-4, a kind of minitype acoustic generator 1, it comprises pedestal 3 and the loam cake 2 that is connected with pedestal 3.The metal pin 9 that pedestal 3 is provided with welding muscle 31 and extends through welding muscle 31 bottoms.Metal pin 9 is provided with the fixed part 91 that is fixed on the 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, loam cake 2 also is provided with and welds the baffle plate 8 that muscle 31 is 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 welding muscle 31 common accepting grooves 7 that form.Because metal pin 9 is extended through welding muscle 31 bottoms, welding muscle 31 needs metal pin 9 processings of stepping down, thereby there is slit 6 in feasible the welding between muscle 31 and the 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 have slit 6 between welding muscle 31 and the metal pin 9, need slit 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 the muscle 31, because glue 4 tool toughness, it can flow to slit 6 and slit 6 is sealed, simultaneously because the existence of baffle plate 8 is arranged, can block glue 4, though also there is slit 6 in baffle plate 8 with metal pin 9 butt places, but because slit 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, come in contact bad problem when having avoided minitype acoustic generator of the present invention and other products to be used contact site 93.
The present invention also provides a kind of minitype acoustic generator, it is identical substantially with above-mentioned minitype acoustic generator 1, different is: plate washer 8 is not arranged on the loam cake 2, but pedestal 3 is provided with and welds the baffle plate 8 that muscle 31 is oppositely arranged, and baffle plate 8 is between faying face 5 and welding muscle 31.More excellent, baffle plate 8 and loam cake 2 butts.
Compare with correlation technique, the present invention is because of 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 flow in the slit and solidifies, with gap sealing not because of tool toughness.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, problem can not occur, and then improve the performance of minitype acoustic generator of the present invention because of the contaminated loose contact that occurs of the connecting portion of metal pin.
Above-described only is embodiments of the present invention, should be pointed out that for the person of ordinary skill of the art at this, under the prerequisite that does not break away from the invention design, can also make improvement, but these all belongs to protection scope of the present invention.
