Abstract

The utility model discloses a standing wave speaker disappears, which comprises a housin, the sound hole is seted up out to one side of casing, the internal face of casing coats and is stamped at least one deck noise damping layer. The utility model discloses a reach the reflection of reduction sound at the back cavity at shells inner wall face cover one deck or multilayer noise damping layer to the maxmizing degree reduces the mesh of standing wave.

Description

Disappear standing wave loud speaker

Technical field

The utility model relates to loudspeaker techniques field, particularly relates to one and to disappear standing wave loud speaker.

Background technology

Existing loud speaker is generally arranged in housing 1 as shown in Figure 1, and the inner chamber of housing 1 is divided into ante-chamber 5 and back cavity, and the cavity ante-chamber 5 refers to from vibrating diaphragm 3 to phonate hole, back cavity is the part that the internal volume of loud speaker deducts after ante-chamber 5.Current loud speaker back cavity reduces standing wave by inserting deadener (deadener is attached to rear inner cavity surface by extruding or sticking double faced adhesive tape), can not eliminate or reduce the reflection not covering inner surface.

Utility model content

Technical problem to be solved in the utility model is: provide a kind of standing wave loud speaker that disappears effectively can eliminating standing wave.

In order to solve the problems of the technologies described above, the technical solution adopted in the utility model is: provide one to disappear standing wave loud speaker, comprise housing, the side of described housing sets out sound hole, the internal face of described housing is coated with at least one deck noise reduction layer.

Further, the internal face of the back cavity of described noise reduction layer covering shell.

Further, the material of described noise reduction layer is foam.

Further, the material of described noise reduction layer is flannelette.

The beneficial effects of the utility model are: the utility model reaches the reflection of reduction sound at back cavity by covering one or more layers noise reduction layer in inner walls face, thus reaches the object at utmost reducing standing wave.

Accompanying drawing explanation

Fig. 1 is the part-structure schematic diagram of the loud speaker of prior art;

Fig. 2 is the structure cutaway view of the standing wave loud speaker that disappears of the utility model embodiment.

Label declaration:

1, housing; 2, sender; 3, vibrating diaphragm; 4, noise reduction layer; 5, ante-chamber.

Embodiment

By describing technology contents of the present utility model in detail, realized object and effect, accompanying drawing is coordinated to be explained in detail below in conjunction with execution mode.

The design of the utility model most critical is: the internal face of the utility model housing 1 is coated with at least one deck noise reduction layer 4, thus reaches the reflection of reduction sound at back cavity, and the utility model can effectively low standing wave.

Refer to Fig. 2, the utility model disappears standing wave loud speaker, and comprise housing 1, the side of described housing 1 sets out sound hole, and vibrating diaphragm 3 is suitable with sender, the internal face of described housing 1 is coated with at least one deck noise reduction layer 4.

From foregoing description, the beneficial effects of the utility model are: the utility model reaches the reflection of reduction sound at back cavity by covering one or more layers noise reduction layer 4 at housing 1 internal face, thus reaches the object at utmost reducing standing wave.

Further, the internal face of the back cavity of described noise reduction layer 4 covering shell 1.

Further, the material of described noise reduction layer 4 is foam.

Further, the material of described noise reduction layer 4 is flannelette.

Please refer to Fig. 2, embodiment one of the present utility model is: the present embodiment disappears standing wave loud speaker, comprises housing 1, sound hole 2 is set out in the side of housing 1, vibrating diaphragm 3 is suitable with sender 2, and the internal face of the back cavity of housing 1 is coated with one deck noise reduction layer 4, the material of this noise reduction layer 4 is foam.

In sum, what the utility model provided disappear standing wave loud speaker, effectively can reduce reflection, and effectively reduce standing wave.

The foregoing is only embodiment of the present utility model; not thereby the scope of the claims of the present utility model is limited; every equivalents utilizing the utility model specification and accompanying drawing content to do; or be directly or indirectly used in relevant technical field, be all in like manner included in scope of patent protection of the present utility model.

Claims

1. disappear a standing wave loud speaker, comprises housing, and the side of described housing sets out sound hole, it is characterized in that, the internal face of described housing is coated with at least one deck noise reduction layer.

2. the standing wave loud speaker that disappears according to claim 1, is characterized in that, the internal face of the back cavity of described noise reduction layer covering shell.

3. the standing wave loud speaker that disappears according to claim 1 and 2, is characterized in that, the material of described noise reduction layer is foam.
