The utility model discloses form the battery storage tank behind one's back at the mainboard of center, be equipped with the keynote chamber at the lower extreme of battery storage tank, be equipped with two vice sound chambeies, the so more cell -phone inner spaces of make full use of in the left and right sides in keynote chamber to very big increase the volume in cell -phone sound chamber, make tone quality can obtain the leap and promote, the keynote chamber is equipped with the through -hole that communicates respectively with two vice sound chambeies, and such setting up makes the sound can be from the keynote chamber rapidly in diffusion to the vice sound chamber, and it is long -pending to increase the sound cavity, promotion tone quality effect.
Description
Technical field
This utility model relates to mobile phone technique field, particularly to the audio cavity structure of a kind of mobile phone.
Background technology
Mobile phone the most on the market develops towards ultrathin, but externally the requirement of playback matter does not the most reduce.
How to make full use of the inner space of mobile phone, the requirement reaching to do thin and outer playback matter first-class is mobile phone
One great difficult problem of design.Tonequality to be carried out, and on the one hand selects outside the loudspeaker of high-quality, on the other hand
The sound cavity volume mated with loudspeaker is accomplished in the rear sound chamber wanting loudspeaker.But most of the time, mobile phones design
Time always have subregion to make full use of so that sound chamber is difficult to do big, and tonequality is also difficult to promote.
Utility model content
This utility model is for the disappearance of prior art existence, it is provided that one is provided that the outer playback matter of high-quality
The audio cavity structure of mobile phone.
For achieving the above object, this utility model uses such as purgation technical scheme:
The audio cavity structure of a kind of mobile phone, including center, described center is provided with mainboard, described mainboard
Being formed with battery accommodating groove behind, the lower end of described battery accommodating groove is provided with keynote chamber, described keynote chamber
The left and right sides be provided with two secondary sound chambeies, described keynote chamber is provided be respectively communicated with two secondary sound chambeies logical
Hole, described keynote intracavity is provided with loudspeaker, and the both sides of described center are provided with and are respectively communicated with two secondary sound chambeies
Opening.
As a kind of preferred version, the opening part of the both sides of described center is provided with Air Filter.
As a kind of preferred version, described keynote intracavity is additionally provided with the support for fixing loudspeaker.
This utility model compared with prior art, has the following advantages and advantage, specifically, in
The mainboard of frame forms battery accommodating groove behind, is provided with keynote chamber in the lower end of battery accommodating groove, at keynote
The left and right sides in chamber is provided with two secondary sound chambeies, so makes full use of more interior of mobile phone space,
Thus significantly increase the volume in mobile phone sound chamber, enable tonequality to obtain leap and promote；Keynote chamber sets
Having the through hole being respectively communicated with two secondary sound chambeies, such setting makes sound can expand rapidly from keynote chamber
It is dissipated in secondary sound chamber, strengthens sound cavity volume, promote acoustical quality；Described center both sides are provided with and two
The opening that secondary sound chamber is respectively communicated with, the setting of opening makes sound outer to be rapidly dissipated in air, outside lifting
Playback matter.
By more clearly illustrate architectural feature of the present utility model, technological means and reached concrete
Purpose and function, come with specific embodiment to make this utility model the most below in conjunction with the accompanying drawings
Bright:
Accompanying drawing explanation
Fig. 1 is the package assembly schematic diagram of the embodiment of this utility model.
Accompanying drawing identifier declaration:
1-center, 2-mainboard, 3-battery accommodating groove,
4-keynote chamber, 5-pair sound chamber, 6-through hole,
7-loudspeaker, 8-opening, 9-Air Filter.
Detailed description of the invention
As it is shown in figure 1, the audio cavity structure of a kind of mobile phone, including center 1, described center 1 is provided with mainboard
2, the behind of described mainboard 2 is formed with battery accommodating groove 3, and the lower end of described battery accommodating groove 3 is provided with master
Sound chamber 4, the left and right sides in described keynote chamber 4 is provided with two secondary sound chambeies 5, and described keynote chamber 4 is provided with and two
The through hole 6 that individual secondary sound chamber 5 is respectively communicated with, is provided with loudspeaker 7, the both sides of described center 1 in described keynote chamber 4
It is provided with the opening 8 being respectively communicated with two secondary sound chambeies 5.It is provided with anti-at the opening 8 of the both sides of described center 1
Dirt net 9.The support for fixing loudspeaker 7 it is additionally provided with in described keynote chamber 4.
In sum, this utility model is by forming battery accommodating groove behind at the mainboard of center, at electricity
The lower end of pond storage tank is provided with keynote chamber, is provided with two secondary sound chambeies in the left and right sides in keynote chamber, so
One makes full use of more interior of mobile phone space, thus significantly increases the volume in mobile phone sound chamber,
Enable tonequality to obtain leap to promote；Keynote chamber is provided with the through hole being respectively communicated with two secondary sound chambeies, this
The setting of sample makes sound can diffuse to rapidly, in secondary sound chamber, strengthen sound cavity volume, promote from keynote chamber
Acoustical quality；Described center both sides are provided with the opening being respectively communicated with two secondary sound chambeies, the setting of opening
Make sound outer to be rapidly dissipated in air, promote outer playback matter.
The above, be only preferred embodiment of the present utility model, not in order to limit this practicality
Novel, thus every according to technology of the present utility model reality above example is made any amendment,
Equivalent, improvement etc., all still fall within the range of technical solutions of the utility model.
