Detailed Description
The utility model discloses technical scheme's novel play ripples structure suitable for ultra-thin speaker, the aim at that the technical means implemented will reach solves traditional play ripples structure because of mostly circular or directed circular and occupation space is big, leads to often to demonstrate lower matching degree and higher limitation when assembling in ultra-thin speaker, and this can make the ultra-thin speaker height (being thickness) of design or assembly be difficult to control, can't prescribe a limit to the holistic size of speaker.
The technical proposal of the utility model is mainly to solve the technical problem by optimizing the shape and the structure of the elastic wave. In addition, because the purpose that the bullet ripples design was used is different with the demand, the utility model discloses technical scheme focus is on the bullet ripples structure, especially under it is applied to ultra-thin speaker state, obviously, the utility model discloses a technical scheme does not just relate to corresponding technical means such as bullet ripples material, local size yet, and the technical staff in the field all knows, as long as can implement the utility model discloses technical scheme concrete structure all belongs to the conventional technical means in this field to the selection such as the material of bullet ripples, local size, and further, the utility model discloses the embodiment need not more and will refine out through the bullet ripples structure of implementing such as different sizes, materials, and these all can refer to the utility model discloses technical scheme implements, and the usable technical means in this field of technical staff in the field accomplishes, and it is unrealistic if all enumerate. Therefore, the utility model discloses the technical scheme who implements is a structure that can let the bullet ripples optimization that technical staff in the field combines conventional technological means to refer to and implement in fact, and the technical staff carries out practical application and test according to the product structure that this application formed according to application condition and the application demand of difference, can actually obtain its a series of advantages of bringing, and these advantages will gradually embody in following analysis to the system architecture.
As shown in fig. 1-8, the novel damper structure applied to the ultra-thin speaker according to the present invention includes a damper body 1 having a rectangular structure, wherein a plurality of assembling holes are formed on the surface of the damper body 1, and the assembling holes on the left and right sides form a voice coil fixing hole 2 for mounting a voice coil assembly 7 (see fig. 6-7 for specific assembling manner).
Correspondingly, the implemented damper body 1 sets up a set of strip-shaped corrugated structures at the edges of two long sides of the rectangular structure respectively along the length direction (i.e. the long side of the rectangle or the length direction of the applied speaker), each set of corrugated structures is composed of a plurality of elastic corrugations 3 arranged at intervals, and a spacing hole 4 is arranged between every two adjacent elastic corrugations 3, the elastic corrugations 3 are arch-shaped structures and all the elastic corrugations 3 located in the same set are located on the same straight line, and simultaneously, the elastic corrugations 3 are arranged into two strips at the edges of two long sides of the damper body 1 respectively, and the length of each strip is smaller than that of the damper body 1. The two implemented corrugated structures are arranged at the periphery of the voice coil assembly 7, and after the voice coil assembly 7 is assembled in the corresponding voice coil fixing hole 2, the periphery of the voice coil assembly 7 is not laminated with the surrounding corrugated structures, but is replaced by a plurality of elastic corrugations 3, and the functions of the corrugations can be stably exerted, so that the defect that the overall thickness of the loudspeaker is increased due to the height increase of the applied loudspeaker voice coil part can be avoided through the elastic corrugations 3.
Furthermore, the edge of the elastic wave body 1 outside each group of the implemented corrugated structures extends outwards horizontally to form a bonding part 5 for directly bonding the loudspeaker drum paper, two wide sides of the implemented elastic wave body 1 form side positions 6, and the area is free of any elastic corrugation 3, meanwhile, a sufficient distance is reserved between each side position 6 and the inner wall surface of the loudspeaker body 8 to perform other loudspeaker auxiliary design, the defect that no other assembling space exists because the traditional elastic wave is completely attached to the inner wall surface of the loudspeaker body 8 is overcome (specifically, reference can be made to fig. 6 and 8 for comparison), and the side positions 6 do not need to be attached to the loudspeaker body 8, so that the length of the loudspeaker body 1 is reduced, and the size of the ultrathin loudspeaker is further reduced.
