Description
Technical field
The utility model relates to speaker field more particularly to a kind of small-size sound boxes.
Background technique
The volume of loudspeaker acoustic enclosure is intended to miniaturization, and vertical well known, speaker is smaller, and acoustic characteristic is poor, and
Speaker is bigger, and acoustic characteristic is better, and sound quality is also better, and two kinds are conflicting but be to coexist, therefore, present loudspeaker
Development, be in a limited space in, maximize volume by various methods so that under the same volume state, sound quality
Reach maximum promotion, become industry and need long-term research and a large amount of experiment, by structure, the various aspects such as material into
Row is promoted.
Utility model content
The utility model discloses a kind of small-size sound boxes, with so as to solve the deficiencies in the prior art.
To solve the above problems, the technical solution of the utility model is:
A kind of small-size sound box, including lower cover and upper cover are provided with multiple upward protrusions, multiple protrusions in the lower cover
Inside magnet is installed, washer is provided with above magnet, is provided with internal frame body above washer, internal frame body is by upper cavity part and cavity of resorption
Portion's composition, lower cavity part are mounted on the outside of multiple protrusions, and voice coil is equipped in upper cavity part, is equipped with bulging paper, epicoele above voice coil
Portion side is provided with a notch, and upper cover is the framework of lower openings, and upper cover top is provided with notch, and drum paper is mounted on upper cover
Upper notch in, lower cover is then mounted in the framework of upper cover lower part, and the wall thickness of upper cover and lower cover is less than 0.4mm.
The upper cover and lower cover are metal material.
The beneficial effects of the utility model are: making sound transmission lengthening distance by the multilayer framework in structure, adopting simultaneously
With metal shell, make in the case where guaranteeing speaker constancy of volume, can effectively increase internal sound communication space, promotes sound quality.
Detailed description of the invention
Fig. 1 is the structural schematic diagram of the utility model；
In: 1- lower cover, 2- upper cover, 3- magnet, 4- washer, 5- internal frame body, 6- voice coil, 7- drum paper, the upper notch of 21-, 51-
Upper cavity part, 52- lower cavity part, 53- notch.
Specific embodiment
Specific embodiment of the present utility model is described in further detail with reference to the accompanying drawing.
Referring to attached drawing 1, the utility model includes lower cover 1 and upper cover 2, is provided in the lower cover 1 multiple upward convex
11 are played, multiple raised 11 insides are equipped with magnet 3, and it is provided with washer 4 above magnet 3, internal frame body 5 is provided with above washer 4,
Internal frame body 5 is made of upper cavity part 51 and lower cavity part 52, and lower cavity part 52 is mounted on multiple raised 11 outsides, is equipped in upper cavity part
Voice coil 6 is equipped with bulging paper 7 above voice coil 6, and 51 side of upper cavity part is provided with a notch 53, and upper cover 2 is the frame of lower openings
Body, 2 top of upper cover are provided with notch 21, and drum paper 7 is mounted in the upper notch 21 of upper cover 2, and lower cover 1 is then mounted under upper cover 2
In the framework in portion, the wall thickness of upper cover 1 and lower cover 2 is less than 0.4mm.
The lower cover 1 and upper cover 2 is metal material.
In practical applications, lower cover 1 and upper cover 2 are metal material, generally use aluminium alloy, stainless steel and other metal materials,
Its wall thickness is less than 0.4mm, is internally provided with internal frame body 5, voice coil 6, shape between internal frame body 5 and upper cover 2 are provided in internal frame body 5
At there is cavity portion, sound wave also will continue to be propagated between cavity portion, increase after internal frame body 5 by notch 53
The communication space of sound, increases volume indirectly, improves sound quality, while using main body of the metal as upper cover 2 and lower cover 1
Material, reduces the resonant frequency of speaker, also improves the performance of loudspeaker.
Above-mentioned specific embodiment is the preferred embodiment of the utility model, can not be defined to the utility model,
Other any changes made without departing from the technical solution of the utility model or other equivalent substitute modes, are included in
Within the protection scope of the utility model.
