Description
[technical field]
This utility model relates to a kind of electroacoustic conversion art, particularly relates to a kind of speaker.
[background technology]
A kind of speaker of correlation technique, it includes housing and the sounding monomer being contained in described housing,
Described housing is separated into upper cavity and the lower chamber relative with described upper cavity, institute by described sounding monomer
State housing and be provided with sidewall and run through the passage of speaking of described sidewall, described in speak passage and described upper cavity
Connection forms the ante-chamber of described speaker.Sound wave during ante-chamber is outwards propagated, ante-chamber resonance meeting
Causing speaker frequency response a formant the highest occur at intermediate frequency, this formant can effective dilazep
High frequency frequency response, widens speaker frequency band.But, the too high meeting of formant causes speaker tonequality front
At cavity resonant frequency the most ear-piercing, distortion is higher.
Therefore, it is necessary to provide a kind of new speaker to solve above-mentioned technical problem.
[utility model content]
The purpose of this utility model is to provide a kind of speaker that can improve distortion.
The technical solution of the utility model is as follows:
A kind of speaker, it includes housing and the sounding monomer being contained in described housing, described sounding

Have sidewall and run through the passage of speaking of described sidewall, described in passage of speaking connect formation with described upper cavity
The ante-chamber of described speaker, described sidewall include surrounding described in speak passage upper side wall and with described on
The lower side wall that side wall is relative, described speaker is provided with the described upper side wall of connection and the connection of described lower side wall
Wall, described connection wall, described upper side wall and described lower side wall surround a noise elimination cavity, described company jointly
Connect wall at it towards being provided with through hole on the wall of described upper cavity, described through hole connect described noise elimination cavity and
Described upper cavity.
Preferably, described upper side wall is a cover plate being spliced to form described housing.
Preferably, described cover plate is provided with the upper surrounding body extended to described lower side wall direction, described lower side wall
Being provided with the lower surrounding body extended to described cover plate direction, described upper surrounding body and described lower surrounding body are spliced to form institute
State connection wall.
Preferably, described through hole is arranged at described upper surrounding body or is arranged at described lower surrounding body or setting
Intersection in described upper surrounding body and described lower surrounding body is spliced jointly by described upper surrounding body and described lower surrounding body
Form.
The beneficial effects of the utility model are: the speaker that this utility model provides arranges connection wall and exists
Speak and passage cut off a muffler chamber, noise elimination cavity by be arranged at the through hole that connects on wall with
Upper cavity connects, and can control being total to of noise elimination cavity by controlling noise elimination cavity and the size of through hole
Vibration frequency so that it is consistent with the front cavity resonant frequency of speaker.The process that sound wave is outwards propagated from ante-chamber
In, noise elimination cavity plays the effect of filtering, is effectively reduced ante-chamber formant, improves the mistake of speaker
Very.

[detailed description of the invention]
The utility model is described in further detail with embodiment below in conjunction with the accompanying drawings.
As shown in Figure 1 to Figure 3, the speaker 1 provided for this utility model, it includes housing 10 He
It is contained in the sounding monomer 20 in described housing 10.In the present embodiment, under described housing 10 includes
Shell 11, with described lower casing 11 lid connect surround cavity upper casing 12 and lid be connected to described upper casing 12
Cover plate 13, now, cover plate 13 is an individual components being spliced to form described housing 10.
Described sounding monomer 20 described housing 10 is separated into upper cavity 30 and with described upper cavity 30
Relative lower chamber (sign) it can be understood as: described upper cavity 30 assembles for sounding monomer 20
After housing 10, the top cavity of speak side namely the sounding monomer 20 of sounding monomer 20, described under
Cavity is after sounding monomer 20 is assembled in housing 10, the lower section cavity of sounding monomer 20.
In the present embodiment, described upper casing 12 is provided with sidewall 12a and runs through speaking of described sidewall 12a
Passage 40, described in passage 40 of speaking connect the ante-chamber forming described speaker 1 with described upper cavity 30,
Described sidewall 12a include surrounding described in speak passage 40 upper side wall 131 and with described upper side wall 131
Relative lower side wall 121.In the present embodiment, cover plate 13 is spliced to form the only of housing 10 as one
Vertical parts and upper casing 12 jointly define speak passage 40 it can be understood as: the lower surface of cover plate 13
131 as surrounding the upper side wall 131 of passage 40 of speaking, and in fact, now cover plate 13 act as upper casing
A part of side wall construction of 12.Certainly, in other embodiments, cover plate 13 is all right with upper casing 12
Being integrative-structure, now, cover plate 13 is exactly a part for upper casing 12 rather than splices with upper casing 12
Individual components, in such embodiments, upper side wall 131 and lower side wall 121 are all as upper casing 12
Sidewall 12a on structure.
Described speaker 1 is provided with the described upper side wall 131 of connection and the connection wall 50 of described lower side wall 121,
Described connection wall 50, described upper side wall 131 and described lower side wall 121 surround a noise elimination cavity 60 jointly,
Described connection wall 50 is provided with through hole 70, described through hole 70 at it on the wall of described upper cavity 30
Connect described noise elimination cavity 60 and described upper cavity 30.
Described cover plate 13 is provided with from the lower surface 131 (upper side wall 131) of cover plate 13 to described lower side wall
The upper surrounding body 132 that 121 directions extend, described lower side wall 121 is provided with and extends to described cover plate 13 direction
Lower surrounding body 122, described upper surrounding body 132 and described lower surrounding body 122 are spliced to form described connection wall 50.
In the present embodiment, described through hole 70 is arranged at described upper surrounding body 132 and described lower surrounding body 122
Intersection and be jointly spliced by described upper surrounding body 132 and described lower surrounding body 122.Certainly, exist
In other embodiments, described through hole 70 can also be separately set in described upper surrounding body 132 or individually set
It is placed on described lower surrounding body 122.
The speaker that this utility model provides arranges connection wall and cuts off a silencing cavity in passage of speaking
Body, noise elimination cavity is connected with upper cavity by being arranged at the through hole connected on wall, can be disappeared by control
Operatic tunes body and the size of through hole, control the resonant frequency of noise elimination cavity so that it is with the ante-chamber of speaker
Resonant frequency is consistent.Sound wave is during ante-chamber is outwards propagated, and noise elimination cavity plays the effect of filtering,
It is effectively reduced ante-chamber formant, improves the distortion of speaker.
Above-described is only embodiment of the present utility model, it should be noted here that for this area
Those of ordinary skill for, without departing from this utility model create design on the premise of, it is also possible to do
Go out to improve, but these belong to protection domain of the present utility model.
