It connects and is connected with the sound channel 4 of leading.In present embodiment, the through-hole 22 is set through the upper cover 2, and shape is unlimited, can
For rectangle, circle or other shapes.More preferably, the through-hole 22 is set with 3 face of sounding monomer.
The sheet metal 23 is covered on the through-hole 22 and is fixed on the body part 21 completely, audio property for improving
Can, the sheet metal 23 includes the perforation 231 through thereon.It ibid manages, 231 shapes of the perforation are unlimited, can be rectangle, circle
Or other shapes.The perforation 231 is set with 3 face of sounding monomer.
In present embodiment, the sheet metal 23 preferably steel disc, thickness 0.2mm.
The flexible material layer 5 is covered on the perforation 231 and is fixed on the sheet metal 23 completely, described for absorbing
The vibrational energy of ante-chamber 101, especially higher hamonic wave energy.So as to avoid the loudspeaker enclosure 100 can be produced in distortion 2 times, 3
Inferior distortion spike improves the sense of hearing of vocal performance.
Specifically, the flexible material layer 5 is made of glue material, such as solid high-temperature sulphurated siliastic.Certainly it is also and unlimited
It is made in this or other sound-absorbing materials.More preferably the flexible material layer 5 is made of liquid-state silicon gel.The liquid-state silicon gel
The performances such as elasticity, tearing toughness, mobility it is more excellent with respect to solid high-temperature sulphurated siliastic.
In present embodiment, the flexible material layer 5 takes shape in the sheet metal 23 by extrusion molding mode.Extrusion molding mode can
Thin the flexible material layer 5 to be done, in thickness direction space requirement smaller, high degree ensures the cavity of the ante-chamber 101
Volume.
Specifically, the flexible material layer 5 includes main wall 51 and outwardly extending solid by the periphery of the main wall 51
Determine wall 52.The main wall 51 and the perforation 231 faces setting, the fixation wall 52 is double-layer structure and sandwiched is fixed respectively
In the both sides of the sheet metal 23.The double-layer structure of the fixation wall 52 strengthens fixing intensity, improves the loudspeaker enclosure
100 reliability.
More preferably, the thickness of the main wall 51 is 0.2mm, and every a layer thickness of the fixation wall 52 is 0.1mm, is formed
Rubber-wrapping structure strengthens its reliability.Therefore when using the loudspeaker enclosure 100, it is only necessary to additional to the avoidance for making 0.1mm
.
The perforation 231 connected with the ante-chamber 101 is covered on by the flexible material layer 5 in the present invention, and
There are a resonant frequencies for the flexible material layer 5, and by design, the resonant frequency of the flexible material layer 5 is adjusted to certain
During one frequency, near resonant frequency, when 100 sounding of loudspeaker enclosure, can by the ante-chamber 101 be located at it is described soft
Property material layers 5 resonant frequency near energy pass to the external world, so as to achieve the purpose that absorb resonant frequency near energy,
Avoid the generation of distortion spike and distortion bad phenomenon.
It is designed to realize above-mentioned mesh especially by material, area, shape and the thickness to the flexible material layer 5
's.In present embodiment, flexible material layer 5 forms the part-structure of the ante-chamber 101, absorbs the institute of the loudspeaker enclosure 100
The energy near 101 resonance peak of ante-chamber is stated, reaches the distortion spike for weakening the ante-chamber 101, and then improve the loudspeaker enclosure
100 acoustical behavior.
Incorporated by reference to shown in Fig. 4, the present invention also provides a kind of assembly method of above-mentioned loudspeaker enclosure, this method includes following step
Suddenly：
Step S41, sheet metal extrusion molding flexible material formable layer：The sheet metal 23 is treated into extrusion molding position glue spraying, by institute
5 extrusion molding of flexible material layer is stated to be molded in the sheet metal 23.
In this step, the purpose of glue spraying is that the sheet metal 23 is detached from the flexible material layer 5 in order to prevent, improves it
Reliability.
The flexible material layer 5 is made of glue material, such as solid high-temperature sulphurated siliastic.Certainly this is also not limited to,
It can be made of other sound-absorbing materials.More preferably the flexible material layer 5 is made of liquid-state silicon gel.The elasticity of the liquid-state silicon gel,
The performances such as tearing toughness, mobility are more excellent with respect to solid high-temperature sulphurated siliastic.
Step S42, it is molded sheet metal：By the sheet metal 23 after flexible material layer 5 described in extrusion molding and 2 note of upper cover
It is moulded into type.
Step S43, other component assemblings.This step includes the assembling of the 1 grade components of fixation and lower cover of sounding monomer 3, than
Such as, the lower cover 1 is made to be formed with the upper cover 2 by ultrasonic bonding to fix.It should be noted that other components in this step
Assembling be conventional assembly method, do not repeating herein.
In this assembly method, the mold of extrusion molding flexible material layer 5 is smaller, and same volume mold can open more die cavitys, cost
It is relatively low.
Incorporated by reference to ginseng Fig. 5, in addition the present invention also provides a kind of assembly method of above-mentioned loudspeaker enclosure, this method and above-mentioned dress
Method of completing the square is essentially identical, and not existing together is equivalent to the first two steps and carries out changing sequence, and this method comprises the following steps：
Step S51, it is molded sheet metal：By the sheet metal 23 and 2 injection molding of upper cover.
Step S52, sheet metal extrusion molding flexible material formable layer：It will be with the sheet metal 23 upper cover after injection molding
2 carry out extrusion molding processing, and 5 extrusion molding of flexible material layer is made to be molded in the sheet metal 23；
Step S53, other component assemblings.
In this method, flexible material layer 5 needs not move through the hot environment of injection, and processing procedure more insures, risk smaller, reliably
Property is stronger.
Compared with the relevant technologies, loudspeaker enclosure of the invention and its assembly method open up and the ante-chamber in the upper cover
The through-hole of connection, and sheet metal cover is set to form fixation set on through-hole, for improving audio performance；Simultaneously on the sheet metal
Setting sets flexible material layer to take shape in the sheet metal by extrusion process through perforation thereon, makes the flexible material
Matter layer is covered on the perforation and forms fixation, the higher hamonic wave in the ante-chamber is absorbed by the flexible material layer, so as to drop
Low ante-chamber resonance peak and distortion, and then improve the acoustical behavior of the loudspeaker enclosure.
Above-described is only embodiments of the present invention, it should be noted here that for those of ordinary skill in the art
For, without departing from the concept of the premise of the invention, improvement can also be made, but these belong to the protection model of the present invention
It encloses.
