Abstract
The invention discloses a mobile terminal with a sound amplifying function; the mobile terminal comprises a main circuit board which is provided with a loudspeaker; the loudspeaker is respectively provided with a sound amplifying cavity on the front surface and the back surface of the main circuit board; a sealing region is formed by using a foam ring for separating the periphery of the loudspeaker; and a through hole is arranged on the main circuit board inside the sealing region. The mobile terminal is simple in structure; and a very great practical effect can be obtained by partly transforming the main circuit board in the mobile terminal. The structure of the mobile terminal leads a mobile phone to have a larger back sound cavity, thereby the sound effect and sound quality of the sound amplification of the mobile phone, particularly the low sound part of sound are increased.
Description
Technical field
The present invention relates to technical field of mobile terminals, particularly relate to a kind of mobile terminal with sound amplification function, it can improve sound amplification effect.
Background technology
Mobile terminal, mobile communication terminal, refers to the computer equipment that can use in movement.Saying of broad sense comprises that mobile phone, notebook even comprise vehicle-mounted computer etc.Yet, typically refer to mobile phone or there is the smart mobile phone of multiple application function.
Along with network and technology are towards more and more broadband future development, Mobile Communication Industry will move towards the real mobile message epoch.The use coverage rate of mobile terminal has reached a quite broad scope.
At present the mobile phone recoverable amount of China has surpassed 400,000,000, and first generation analog communication is superseded in last century Mo, current universal be second generation digital communication mobile phone and 3G (Third Generation) Moblie mobile phone (3G).Current most mobile phone, except the basic functions such as clock, call and note, also supports handwriting input, MP3, MP4 to play, take pictures and the function such as shooting, can be used for listening to the music, see a film, playing games, and also some mobile phone has GPS navigation function.
Yet mobile phone is because volume is little, inner space is less, so sound chamber is difficult to do greatly.This just causes the audio amplifying by mobile phone not good, cannot reach the audio that people amplify for mobile phone, the requirement of tonequality.
Summary of the invention
The technical problem to be solved in the present invention is in order to overcome the not good defect of sound amplification effect in prior art, a kind of mobile terminal with sound amplification function to be provided, having good sound amplification effect.
The present invention solves above-mentioned technical problem by following technical proposals: a kind of mobile terminal with sound amplification function, comprise that one is provided with the main circuit board of loudspeaker, its feature is, described loudspeaker respectively have the chamber that amplifies at the positive and negative of described main circuit board, surrounding at described loudspeaker is separated out a sealing area by a foamed cotton ring, and the main circuit board in described sealing area is provided with a through hole.
Preferably, described through hole is circular.
Preferably, the aperture of described through hole is more than or equal to 2mm.
Preferably, the aperture of described through hole is 2-5mm.
Preferably, described through hole is square.
Preferably, the length of side of described through hole is for being more than or equal to 2mm.
Preferably, the length of side of described through hole is 2-5mm.
Preferably, the hole that a diameter is more than or equal to 3mm is offered in the lower surface of described loudspeaker.
Preferably, described mobile terminal is mobile phone.
In the present invention, above-mentioned optimum condition can combination in any on the basis that meets this area general knowledge, obtains each preferred embodiment of the present invention.
Positive progressive effect of the present invention is: the present invention is simple in structure, carries out the transformation of a little by the main circuit board in mobile terminal, can obtain very large actual effect.This structure makes mobile phone have larger rear sound chamber, thus the bass part of audio, tonequality, especially sound that raising mobile phone amplifies.
Accompanying drawing explanation
Fig. 1 is the structural representation that the present invention has main circuit board front in the mobile terminal of sound amplification function.
Fig. 2 is the structural representation that the present invention has main circuit board reverse side in the mobile terminal of sound amplification function.
Embodiment
Below in conjunction with accompanying drawing, provide preferred embodiment of the present invention, to describe technical scheme of the present invention in detail.
As shown in Figure 1 and Figure 2, the mobile terminal that the present invention has a sound amplification function comprises that one is provided with the main circuit board 1 of loudspeaker 2.Loudspeaker 2 described here respectively have the chamber that amplifies at the obverse and reverse of main circuit board.This mobile terminal is mobile phone herein, and its main circuit board is cell phone mainboard.Surrounding at loudspeaker 2 arranges a foamed cotton ring 3, round loudspeaker 2, is separated out a sealing area 5.Wherein, the Packed effect of foamed cotton ring 3 tool.Other any parts are not set on the main circuit board face in whole sealing ring region 5, effectively prevent the interference of electronic component to audio.In addition, on the mainboard in sealing area 5, be provided with a through hole 4, thereby make loudspeaker 2 He Houyin chamber, sound chamber before the positive and negative of main circuit board forms.
Further, the shape of through hole 4 is set to circular or square.Wherein, the aperture of circular through hole is more than or equal to 2mm, is preferably 2-5mm.The length of side of squared-shaped passthrough openings is more than or equal to 2mm, is preferably 2-5mm.By above-mentioned setting, through hole 4 can together, make loudspeaker 2 He Houyin chamber, sound chamber before the positive and negative of main circuit board 1 forms by front sound Qiang Hehouyin chamber UNICOM in handset shell, is equivalent to greatly expand sound chamber, especially rear sound chamber.The amplifying effect of loudspeaker promotes greatly like this, and especially the performance meeting of bass part is better.
Preferably, in the lower surface of loudspeaker 2, offer the hole 6 that a diameter is more than or equal to 3mm.This structure can further expand rear sound chamber, makes the audio of bass part more outstanding.
Certainly, the shape of above-mentioned through hole can change arbitrarily according to actual conditions, is not limited to circular and square.The present invention is simple in structure, easy to implement.Total is only carried out the transformation of a little to the main circuit board of mobile terminal, can obtain very large actual effect.The present invention makes mobile phone have larger rear sound chamber, has greatly improved the bass part of the audio that mobile phone amplifies, tonequality, especially sound.
Although more than described the specific embodiment of the present invention, it will be understood by those of skill in the art that these only illustrate, protection scope of the present invention is limited by appended claims.Those skilled in the art is not deviating under the prerequisite of principle of the present invention and essence, can make various changes or modifications to these execution modes, but these changes and modification all fall into protection scope of the present invention.
