Abstract

The utility model discloses a vibrating board structure for a loudspeaker, with the lower surface of the vibrating board integrated and molded with vesicant materials. Being light in weight and strong in hardness, etc., the vesicant material has ideal supporting function for the vibrating board when being fixed on the lower surface of the vibrating board; meanwhile, the vesicant material does not add weight to the vibrating board. Therefore, in actual use, the structural setting of the vibrating board makes the vibration of the vibrating board in mass motion, and thereby preventing the phenomenon of ''wave'' in conventional like products. Thus, the overall vibrating board has larger vibrating strength and can realize ideal sound effects. Moreover, the vibrating board is simple in structure, convenient in making, and economical in cost.

Description

The loudspeaker vibration board structure

Technical field

The utility model relates to a kind of loudspeaker vibration board structure.

Background technology

At present varied about the form of speaker, its oscillating plate is based on funnel type substantially, install on the limited electric equipment products in the space of audio amplifier at TV etc., mainly be to be equipped with the plane loudspeaker, but the tonequality of these loudspeaker is wayward, reason be since the oscillating plate area of plane loudspeaker more greatly or longer, after it is connected on the loudspeaker casing, as do not have higher hardness and support, then this oscillating plate is when vibration, panel " wave " phenomenon can occur and influence tonequality, but if oscillating plate do the effect of too thick influence vibration again, be that tonequality is not good equally.

The utility model content

The purpose of this utility model is to provide the good loudspeaker vibration board structure of tonequality that a kind of manufacture craft is easy, produce.

For achieving the above object, solution of the present utility model is:

The loudspeaker vibration board structure, wherein the oscillating plate lower surface is one-body molded an expanded material.

Described expanded material is posted solid in the lower surface of oscillating plate.

Described expanded material is arranged at around the oscillating plate lower surface.

After adopting such scheme, the utility model is because the lower surface of oscillating plate is provided with expanded material, and this expanded material has characteristics such as in light weight, that hardness is strong, therefore it is fixed in the lower surface of oscillating plate, oscillating plate had preferable supporting role, do not increase simultaneously oscillating plate weight again, then in actual applications, the structure setting of this oscillating plate, making oscillating plate when vibration, is mass motion, can not occur as commonly using " wave " phenomenon in the product, therefore whole vibration plate vibrates strength is big, and the tonequality that is reached is good; Its manufacture craft of the structure of this oscillating plate is easy in addition, saves cost.

Fig. 2 is that the A-A of Fig. 1 is to cutaway view;

Fig. 3 is the partial enlarged drawing of Fig. 2;

Fig. 4 is that the B-B of Fig. 1 is to cutaway view;

Fig. 5 is the partial enlarged drawing of Fig. 4.

Embodiment

Shown in Fig. 1 to 5, loudspeaker vibration board structure of the present utility model, its key is: be one-body molded on the lower surface 11 of oscillating plate 1 expanded material 2 to be arranged.

This expanded material 2 is to be molded over around oscillating plate 1 lower surface 11.Because this expanded material 2 has characteristics such as in light weight, that hardness is strong, therefore it is fixed in the lower surface 11 of oscillating plate 1, oscillating plate 11 had preferable supporting role, simultaneously do not influence oscillating plate weight again, then in force, this oscillating plate 1 is when vibration, whole plate face is a body vibration, can not occur as commonly using " wave " phenomenon in the product, therefore the vibration force of whole oscillating plate 1 is big, and the tonequality that is reached is good.

Expanded material 2 in the utility model also can be shaped to sheet material separately, can be according to the size of oscillating plate 1 and arbitrarily after the intercepting, be posted solid on the lower surface 11 of oscillating plate 1, can realize above-mentioned functions equally.This kind expanded material 2 is also plastic on the oscillating plate of " funnel type ".

Manufacture craft of the present utility model in addition is easy, and cost is low.

Claims

1, a kind of loudspeaker vibration board structure is characterized in that: the oscillating plate lower surface is one-body molded expanded material.

2, loudspeaker vibration board structure as claimed in claim 1, it is characterized in that: expanded material is posted solid in the lower surface of oscillating plate.

3, loudspeaker vibration board structure as claimed in claim 1 or 2, it is characterized in that: expanded material is arranged at around the oscillating plate lower surface.
