However, in the relevant technologies, the magnetic bowl includes bottom plate and the side plate extended from the bottom plate to vibrational system direction, The side plate is fixed with the frame by the way that glue layer is set to realize.The fixed form fixed effect is unstable, and the magnetic bowl holds It easily comes off from the frame, so as to influence the acoustical behavior of the loud speaker.

Therefore, a kind of new loud speaker must be provided by, which having in fact, solves above-mentioned technical problem.

【Utility model content】

The purpose of this utility model is to provide a kind of good reliability and the high loud speakers of stability.

In order to achieve the above objectives, the utility model provides a kind of loud speaker, including frame, is fixed on the magnetic bowl of the frame With the glue layer that the magnetic bowl is fixed on to the frame；The frame includes side wall, the Inside To Outside side by the side wall Gum box to recess and the dermatoglyph for being formed in the glue rooved face；The magnetic bowl is set with the gum box face, institute It states glue layer to be filled between the magnetic bowl and the gum box, the glue layer is at least partially disposed in the gum box and will The magnetic bowl is fixed on the side wall.

Preferably, the dermatoglyph has the roughness more than VDI18.

Preferably, the magnetic bowl includes bottom plate, the side plate by bottom plate bending extension and the outside by the side plate The groove formed to inward side to recess, the side plate and the side wall of the frame are oppositely arranged, and the glue layer is at least It is partially housed in the groove.

Preferably, the groove includes multiple and is arranged at intervals.

Preferably, multiple groove spaced sets.

Preferably, it the side plate packet two and is oppositely arranged, two side plates are respectively by the opposite sides of the bottom plate It extends to form.

Preferably, the width of the groove is less than the width of the gum box.

Compared with the relevant technologies, the loud speaker of the utility model sets dermatoglyph structure in the gum box of the frame side wall, When forming fixed by setting glue layer between the magnetic bowl and the frame, at least part of the glue layer, which incorporates, to be received It is dissolved in the gum box, and the setting of the dermatoglyph increases the side wall of the frame and the magnetic bowl secure bond Surface area so as to strengthen the bond strength of the two, further improves the stability and reliability of the loud speaker.

【Description of the drawings】

It is required in being described below to embodiment in order to illustrate more clearly of the technical scheme in the embodiment of the utility model Attached drawing to be used is briefly described, it should be apparent that, the accompanying drawings in the following description is only some realities of the utility model Example is applied, it for those of ordinary skill in the art, without creative efforts, can also be according to these attached drawings Other attached drawings are obtained, wherein：

Fig. 1 is the dimensional structure diagram of the utility model loud speaker；

Fig. 2 is the stereochemical structure exploded view of the utility model loud speaker.

【Specific embodiment】

The following is a combination of the drawings in the embodiments of the present utility model, and the technical scheme in the embodiment of the utility model is carried out It clearly and completely describes, it is clear that described embodiment is only the part of the embodiment rather than whole of the utility model Embodiment.Based on the embodiment in the utility model, those of ordinary skill in the art are without making creative work The all other embodiment obtained, shall fall within the protection scope of the present invention.

It please join shown in Fig. 1-2, the utility model provides a kind of loud speaker 100, including frame 1, is individually fixed in frame 1 Vibrational system 2 and magnetic circuit system 3 and glue layer (not shown).

The frame 1 include side wall 11, by the side wall 11 Inside To Outside direction be recessed gum box 12 and shape The dermatoglyph (not shown) on 12 surface of gum box described in Cheng Yu.

In present embodiment, the frame 1 surrounds rectangular configuration by the side wall 11.The dermatoglyph, which has, is more than VDI18 Roughness.VDI is the surface roughness value defined by German engineering specification.

The magnetic circuit system 3 is used to drive 2 vibration sounding of vibrational system.

The magnetic circuit system 3 includes being fixed on the magnetic bowl 31 of the frame 1 and the magnet steel 32 being contained in the magnetic bowl 31.

The magnetic bowl 31 includes bottom plate 311, the side plate 312 of extension is bent by the bottom plate 311 and by the side plate 312 The interior direction of the outer lateral side plate 312 be recessed the groove 313 to be formed.

The magnet steel 32 is fixed on the bottom plate 311, for generating magnetic field.

The side plate 312 and the side wall 11 of the frame 1 are oppositely arranged and are fixed on the side wall 11.Because of the side The surface of the gum box 12 of wall 11 is provided with the dermatoglyph structure, the surface face equivalent to increase the gum box 12 Product after glue, which enters gum box 12, is formed by curing the glue layer, actually increases the side wall 11 and the magnetic bowl 31 The bonded area of the side plate 312 so as to strengthen the fixing intensity of the frame 1 and the magnetic bowl 31, improves described raise The reliability and stability of sound device 100.

In present embodiment, the bottom plate 311 illustrates by taking rectangle as an example, and the side plate 312 includes two and is oppositely arranged, Then the corresponding two side 11 of the frame is equipped with the gum box 12, and 12 surface of gum box is respectively formed the dermatoglyph.

Two side plates 312 extend shape from the opposite sides of the bottom plate 311 to the direction of the vibrational system 2 respectively Into for being fixed with the side wall 11 of the frame 1.Two side plates 312 are oppositely arranged so that the magnetic bowl 31 is fixed The more balance and stability when frame 1.

Certainly, the side plate 312 may also comprise four, be extended to form respectively by the bending of four sides of the bottom plate 311.Together Reason, corresponding four side walls 11 of the frame 1 are also equipped with the gum box 12, this is all feasible, and principle is all Equally.

The groove 313 includes multiple and is arranged at intervals.In present embodiment, multiple 313 spaced sets of groove, Preferably, the width of the groove 313 is less than the width of the gum box 12.

The shape of the groove 313 is unlimited, can rectangular or strip-like-shaped or circle or other shapes, this is all feasible 's.

When the glue layer is filled between the side wall 11 of the frame 1 and the side plate 312 of the magnetic bowl 31, The glue layer is at least partially housed in the groove 313.That is, when glue is driven into the frame 1 and the side After between plate 312, glue forms the glue layer because its mobility can be flowed into partly in the groove 313, when the glue solidifies When so that at least part structure of glue layer is contained in the groove 313.The setting of above-mentioned 313 structure of groove is equivalent to increasing The surface area of secure bond between the side plate 312 and the side wall 11 of the frame 1 is added, so as to further effectively improve The frame 1 and the fixing intensity of the side plate 312, avoid the magnetic bowl 31 and come off from the frame 1.Therefore greatly Degree improves the reliability and stability energy of the loud speaker 100.

Above-described is only the embodiment of the utility model, it should be noted here that the ordinary skill for this field For personnel, under the premise of not departing from the utility model and creating design, improvement can also be made, but these belong to this practicality Novel protection domain.
