Abstract
Disclosed is a mobile phone sound, comprising a sound device arranged therein. The sound device is provided with a sound chamber with a loudspeaker set and an inverter tube which is in communication with the outside. The sound chamber consists of an upper lid and a lower lid of the sound chamber which are connected together so as to form a sealed chamber. One end of the inverter tube is arranged in the sealed chamber and the other end thereof threads through the upper lid or the lower lid of the sound chamber to be in communication with the outside. By improving the sound structure of a prior mobile phone and providing the inverter tube in the sound chamber, the phase in a low-mid frequency of the back acoustic wave of the speaker can be adjusted effectively, the back sound wave and the frontal sound wave of the speaker are overlapped, the sound wave in the low-mid frequency is extended effectively and the sound pressure is increased as well, therefore the low-mid tone is recovered more naturally and clearly with a good sound quality.
Description
Technical field
The utility model relates to a kind of mobile phone sound equipment, specifically a kind of mobile phone sound equipment with the paraphase structure.
Background technology
Along with the progress of the development of society, science and technology, the improving constantly of living standard, people are also more and more higher to the requirement of mobile phone.After the leisure of work, study, people can emit music by mobile phone, and the mood of oneself is loosened.Present mobile phone is generally only sounded in the inner set of speakers of installing of casing, perhaps loud speaker is installed in the simple airtight sound chamber and sounds.More than two kinds of frame modes, all have only the sound wave energy in loud speaker front to access effective utilization, and the sound wave at the loud speaker back side is not used, the lower frequency limit of sound system is higher, mobile phone is when playing back music, the effect of middle bass is generally relatively poor.
The utility model content
It is good that the technical problems to be solved in the utility model provides a kind of acoustical quality, is equipped with the mobile phone sound equipment of phase-reversing tube.
In order to solve the problems of the technologies described above, the utility model is taked following technical scheme:
A kind of mobile phone sound equipment comprises the acoustics of being located in the mobile phone, and this acoustics comprises the sound chamber that is provided with set of speakers, and described sound is provided with the phase-reversing tube that is in communication with the outside in the chamber.
Described sound chamber comprises mutual attaching and forms the sound chamber loam cake and the sound chamber lower cover of airtight cavity that phase-reversing tube one end is located in the airtight cavity, the other end runs through sound chamber loam cake or sound chamber lower cover is in communication with the outside.
The another kind of implementation of the utility model, described sound chamber comprise mutual attaching and form the sound chamber loam cake and the pcb board of airtight cavity that phase-reversing tube one end is located in the airtight cavity, the other end runs through sound chamber loam cake and is in communication with the outside.
Described phase-reversing tube is that hollow tube is made.
The utility model is by the improvement to existing mobile phone acoustic structure, in the sound chamber, install phase-reversing tube, effectively regulate the phase place of loud speaker back side sound wave in the medium and low frequency section, make loud speaker back side sound wave and this loud speaker front sound wave superimposed, thereby the sound wave of medium and low frequency section is effectively extended, and acoustic pressure also obtains to improve accordingly, the clear and natural more of bass reduction in making, obtain better acoustical quality, effectively overcome the not good problem of middle bass tonequality of conventional mobile phone.
Description of drawings
Accompanying drawing 1 is the cross-sectional view of the utility model embodiment one; Accompanying drawing 2 is the cross-sectional view figure of the utility model embodiment two.
Embodiment
Purport of the present utility model is to improve the middle bass tonequality of mobile phone, makes people when using mobile phone to play music, obtains better tonequality and enjoys.The utility model will be further described below in conjunction with accompanying drawing.
As shown in Figure 1, a kind of mobile phone sound equipment comprises the acoustics of being located in the mobile phone, and this acoustics comprises the sound chamber that is provided with set of speakers 1, is equiped with the phase-reversing tube 2 that is in communication with the outside in the sound chamber, and this phase-reversing tube 2 is made for hollow tube.On above-mentioned architecture basics, the utility model has following two kinds of more excellent execution modes, need to prove, the content of mentioning in following examples is not to be to qualification of the present utility model.
Embodiment one, and as shown in Figure 1, the sound chamber comprises mutual attaching and form the sound chamber loam cake 32 and the sound chamber lower cover 33 of airtight cavity 31 that phase-reversing tube 2 one ends are located in the airtight cavity, the other end runs through sound chamber loam cake 32 or sound chamber lower cover 33 is in communication with the outside.
Embodiment two, and as shown in Figure 2, the sound chamber comprises mutual attaching and form the sound chamber loam cake 32 and the pcb board 34 of airtight cavity 31 that phase-reversing tube 2 one ends are located in the airtight cavity 31, the other end runs through sound chamber loam cake 32 and is in communication with the outside.
Need to prove, because the type of mobile phone is varied, and in order to obtain best acoustical quality, the size of the airtight cavity in the sound chamber and shape can specifically be provided with according to the difference of mobile phone, the cross-sectional area of phase-reversing tube and length and at sound chamber loam cake or cover down offer the position, can be not to be to immobilize according to the size and the shape setting of corresponding airtight cavity yet.
