Embodiment

Various exemplary embodiment of the present utility model is described in detail now with reference to accompanying drawing.It should be noted that: unless specifically stated otherwise, otherwise positioned opposite, the numerical expression of the parts of setting forth in these embodiments and step and numerical value do not limit scope of the present utility model.

Illustrative to the description only actually of at least one exemplary embodiment below, never as any restriction to the utility model and application or use.

The technology and equipment known for person of ordinary skill in the relevant may not discuss in detail, but in the appropriate case, described technology and equipment should be regarded as a part for specification.

In all examples with discussing shown here, any occurrence should be construed as merely exemplary, instead of as restriction.Therefore, other example of exemplary embodiment can have different values.

It should be noted that: represent similar terms in similar label and letter accompanying drawing below, therefore, once be defined in an a certain Xiang Yi accompanying drawing, then do not need to be further discussed it in accompanying drawing subsequently.

The utility model provides a kind of loud speaker.With reference to Fig. 3-9, loud speaker comprises shell 1 and the protecgulum 2 for assembling with shell 1, and shell 1 and protecgulum 2 form the cavity that has spatial accommodation, contain magnetic circuit system and the vibrational system of loud speaker in this cavity; Wherein, frame 7, magnet 8 and washer 9 form magnetic circuit system jointly, and voice coil loudspeaker voice coil 10 and vibrating diaphragm 11 form vibrational system jointly.Shell 1 is also provided with screen cloth 6.

In order to the voice coil loudspeaker voice coil 10 making the current signal of loud speaker outside can be passed to vibrational system smoothly, shell 1 is embedded with pad 3, wherein, the first end 301 of pad 3 is electrically connected with the lead-in wire of voice coil loudspeaker voice coil 10, and the second end 302 of pad 3 is electrically connected with external circuit.Like this, when loud speaker is electrically connected with external circuit, current signal then passes through pad 3 conducting to voice coil loudspeaker voice coil 10, and what complete pad 3 thus conducts function.On the other hand, pad second end 302 is provided with the positioning convex 304 towards protecgulum 2 direction, and protecgulum 2 correspondence is provided with the location notch 5 coordinated with positioning convex 304, like this, when protecgulum 2 carries out assembly with shell 1, positioning convex 304 inserts in location notch 5, realizes the location of protecgulum 2 and shell 1.That is, in the technical program, by the design of pad 3 structure, the conducting of inside and outside current signal and the location of shell 1 and protecgulum 2 can be realized simultaneously.

The mode be more preferably is, the height of positioning convex 304 is 0.2mm-1.0mm.Certainly, other height can be also designed to as required.The protrusion direction of positioning convex 304 is vertical with the second end 302.Certainly, the protrusion direction of positioning convex 304 also can become other angles with the second end 302, without restriction to this utility model.

For the ease of processing, pad 3 is U-shaped, the pad 3 of U-shaped while be first end 301, another side is the second end 302, the middle position connected is connecting portion 303, and wherein, the outer ledge of the second end 302 is provided with towards the bending structure near protecgulum 2 direction, this bending structure is above-mentioned positioning convex 304, and it is exposed to the outside of shell.

In order to improve structural strength.Pad 3 adopts stainless steel material, can select SUS301 or SUS304, with shell 1 integrated injection molding.Certainly, also other metallic conductors or nonmetallic materials can be adopted.Location notch 5 is the groove structure that the position of corresponding positioning convex 304 on protecgulum 2 is gone to expect to be formed.Positioning convex 304 due to pad 3 inserts in the location notch 5 of protecgulum 2, when loudspeaker vibration or when being subject to external force, shell 1 and protecgulum 2 have the trend along mating surface movement, due to the positioning convex 304 of pad 3 and the existence of the fit structure of location notch 5, the generation of movement can be stoped, and without the need to arranging the setting element such as reference column or equipotential buckle, thus speaker cover body structure is become simple, simplify processing technology, save space.

Generally, shell is provided with multiple pad 3.In one embodiment, shell 1 is rectangle, and pad 3 is 2, and pad 3 is located at two adjacent corner positions of shell 1, and namely now, voice coil loudspeaker voice coil 10 should in position, the adjacent angle outlet of shell 1.Protecgulum 2 is provided with two location notchs 5 corresponding with the position of positioning convex 304.Pad 3 adopts stainless steel material, one-body molded with shell 1.

In another embodiment, shell 1 is rectangle, and pad 3 is 2, and pad 3 is located at two relative corner positions of shell 1, and namely now, voice coil loudspeaker voice coil 10 should in the diagonal position outlet of shell 1.Protecgulum 2 is provided with two location notchs 5 corresponding with the position of positioning convex 304.Pad 3 adopts stainless steel material, one-body molded with shell 1.

The loudspeaker applications that the utility model provides pad 3, this pad 3 is provided with the positioning convex 304 for locating protecgulum 2, protecgulum 2 is provided with the location notch 5 coordinated with positioning convex 304.The function i ntegration of original pad 3 and setting element 4 in one, is simplified processing technology, saves the space that setting element 4 takies, improve space availability ratio by this pad 3.Be conducive to the miniaturization of loud speaker, lightening.In addition, this loadspeaker structure is simple, and processing and manufacturing is convenient, easy for installation.

Although be described in detail specific embodiments more of the present utility model by example, it should be appreciated by those skilled in the art, above example is only to be described, instead of in order to limit scope of the present utility model.It should be appreciated by those skilled in the art, when not departing from scope and spirit of the present utility model, above embodiment can be modified.Scope of the present utility model is limited by claims.
