Abstract
The utility model relates to a handset sound equipment structure with a low frequency enhancement device. The handset sound equipment structure with the low frequency enhancement device comprises an acoustic chamber arranged in a handset, wherein a casing of the acoustic chamber is equipped with an electric loudspeaker and at least one low frequency radiator. When the electric loudspeaker operates, an air flow generated in the acoustic chamber can promote the low frequency radiator, so work of the electric loudspeaker can be reused, a high frequency band excelled by the electric loudspeaker is filtered by utilizing the low frequency radiator, expression of middle frequency and low frequency is improved, and a low frequency compensation effect is realized.
Description
Technical field
The utility model relates to acoustic structure, is specifically related to Acoustic structure of mobile phone.
Background technology
Existing mobile phone can be play music, but, because interior of mobile phone only has a toy trumpet, the sound sent belongs to high-frequency sound substantially, can not show the sound of high, medium and low three frequency ranges.What the loudspeaker of current mobile phone adopted is piezo-electric loudspeaker, and piezo-electric loudspeaker is due to structural limitations, and the sound sent is high-frequency sound, in inside cavity, can not produce air-flow, so cannot promote the low frequency radiation device.
The utility model content
The purpose of this utility model is to propose a kind of Acoustic structure of mobile phone with low-frequency enhancement devices, and it can solve the problem that current Mobile phone horn can't show the sound of high, medium and low three frequency ranges.
In order to achieve the above object, the technical scheme that the utility model adopts is as follows:
A kind of Acoustic structure of mobile phone with low-frequency enhancement devices, it comprises the acoustics cavity that is arranged on interior of mobile phone, and dynamic speaker and at least one low frequency radiation device are installed on the housing of described acoustics cavity.
Preferably, dynamic speaker and low frequency radiation device are separately positioned on the relative sidewall of housing of acoustics cavity, and dynamic speaker and low frequency radiation device are oppositely arranged.
Preferably, dynamic speaker and low frequency radiation device are arranged on the same sidewall of housing of acoustics cavity.
Preferably, dynamic speaker and low frequency radiation device are arranged on the adjacent wall of housing of acoustics cavity.
Preferably, described acoustics cavity is closed sound chamber.
Preferably, described low frequency radiation device is connected and composed by balancing weight and ring.
The utlity model has following beneficial effect:
The air-flow produced in the acoustics inside cavity during dynamic speaker work can promote the low frequency radiation device, thereby reach the effect that the dynamic speaker work is utilized again, and utilize the low frequency radiation device to filter the high pitch frequency range that dynamic speaker is good at, enlarge the performance of intermediate frequency and low frequency, reach the effect of low-frequency compensation.
The accompanying drawing explanation
The structural representation of the Acoustic structure of mobile phone with low-frequency enhancement devices that Fig. 1 is the utility model embodiment mono-;
The structural representation of the Acoustic structure of mobile phone with low-frequency enhancement devices that Fig. 2 is the utility model embodiment bis-.
Embodiment
Below, by reference to the accompanying drawings and embodiment, the utility model is described further.
Embodiment mono-
As shown in Figure 1, a kind of Acoustic structure of mobile phone with low-frequency enhancement devices, it comprises the acoustics cavity 10 that is arranged on interior of mobile phone, and a dynamic speaker 1 and a low frequency radiation device 2 are installed on the housing of described acoustics cavity 10.The acoustics cavity 10 of the present embodiment is closed sound chamber.
Embodiment bis-
The present embodiment is that from the difference of embodiment mono-relative position of low frequency radiation device and dynamic speaker is different.As shown in Figure 2, dynamic speaker 1 and low frequency radiation device 2 are arranged on the same sidewall of housing of acoustics cavity 10.The operation principle of the present embodiment is identical with embodiment mono-.
It should be noted that, in above-described embodiment, the size shape of low frequency radiation device is unrestricted, shape that can be different according to the acoustics cavity design and size dimension.The position that the low frequency radiation device is installed is also unrestricted, can be in any position of acoustics cavity, and for example, dynamic speaker and low frequency radiation device can also be arranged on the adjacent wall of housing of acoustics cavity.The quantity of low frequency radiation device can be one or more.
For a person skilled in the art, can make other various corresponding changes and distortion according to technical scheme described above and design, and these all changes and the distortion all should belong to the protection range of the utility model claim within.
