Specific embodiment
The following will be combined with the drawings in the embodiments of the present invention, carries out the technical scheme in the embodiment of the utility model
Clearly and completely describe, it is clear that the described embodiments are only a part of the embodiments of the utility model, rather than whole
Embodiment.Based on the embodiments of the present invention, those of ordinary skill in the art are without making creative work
Every other embodiment obtained, fall within the protection scope of the utility model.
A kind of horn mobile phone shell is sheathed on 1 back of mobile phone, and mobile phone 1 includes loudspeaker 10, which includes shell
2；Shell 2 and loudspeaker 10 go out acoustic aperture contact position and are equipped with pressure chamber 20, are additionally provided with air cavity 21, air cavity 21 on shell 2
One end be aditus laryngis 211 and connect with pressure chamber 20, the other end is to be open 212 and directly to contact with air, air cavity 21
Sectional area is gradually increased from 211 end of aditus laryngis to 212 ends of opening.
Sound is directly radiated very big free space from the vibrating diaphragm of very little when loudspeaker 10 works, and the wave surface of sound wave becomes
Change comparatively fast, therefore radiation impedance very little, cause the result of broadcast of loudspeaker 10 poor.
Specifically, loudspeaker 10 is used as audio drivers in the utility model, it is with the pressure chamber 20 being arranged on shell 2
The air pressure lumen of horn is propagation sound channel, that is, stack shell of horn with air cavity 21, is issued with opening 212 for the sound of horn
Mouthful, horn structure is formed, the sound of loudspeaker 10 promotes impedance by the horn structure, and loudspeaker 10 can increase working efficiency,
Distortion, and control sound dispersion angle are reduced, has achieved the effect that improve its play quality and volume.The horn structure simultaneously
It is easily portable as a part of mobile phone shell.The wave surface of horn radiation sound becomes larger from aditus laryngis 211 to opening 212,
It is closed eventually by biggish opening 212 with free surrounding space lotus root, acoustic resistance is bigger, and keep its more efficient, therefore comparatively result of broadcast
More preferably, the working efficiency for thereby increasing the loudspeaker 10 of horn structure is improved.
Further, the area that pressure chamber 20 and loudspeaker 10 go out acoustic aperture contact position is greater than the face that loudspeaker 10 goes out acoustic aperture
Product, and pressure chamber 20 goes out acoustic aperture with mobile phone speaker 10 and fits closely.The setting is to make pressure chamber 20 is fully wrapped around to raise
Sound device 10 goes out acoustic aperture, and so that sound is not leaked outside and cause the loss of energy.
Further, the sectional area of aditus laryngis 211 is less than or equal to pressure chamber 20 in the sectional area with 211 junction of aditus laryngis,
Pressure chamber 20 is set to constitute pressure cavity configuration, since pressure chamber 20 is gradually reduced in the part close to aditus laryngis 211 by the shape of funnel,
When the vibrating diaphragm work of loudspeaker 10, air can be moved and be squeezed, keeps the air being extruded smaller than pressure chamber 20 by sectional area
Aditus laryngis 211, and air velocity can improve, thus also increase the sound radiation impedance of vibrating diaphragm again, reduce loudspeaker distortions.
Further, 20 wall surface of pressure chamber and loudspeaker 10 go out the sound wave direction out of plumb that acoustic aperture issues, and may be guided
Sound wave is passed to aditus laryngis 211 along 20 wall surface of pressure chamber.It avoids sound wave from entering aditus laryngis 211 after vertically reflecting, causes acoustic wave energy
A degree of loss.
Further, it is additionally provided with acoustic lens at opening 212, plays and has broadened the promotion sound quality such as high frequency directive property of loudspeaker
Effect, while 212 playing the role of support reinforcing for large span horn opening.
Further, phase plug is additionally provided at aditus laryngis 211.The sound wave that the diaphragm of loudspeaker pushes can when eventually entering into cavity
Can there is a situation where sonic transmissions apart from different, that is to say, that sound wave is likely to occur phase difference, influences sound effect, in order to avoid
Such case occurs, and increases a phase plug in the appropriate location of aditus laryngis, adjusts the transmission range of acoustic wave segment, reduce and enter chamber
The phase difference of the sound wave in road.
Further, 21 length of air cavity is longer, and the stroke of sound transmission is longer, through the sound for putting sending outside mobile phone
Frequency is lower, i.e., bass effect is better.Specifically, the length of air cavity 21 is greater than hand in the embodiments of the present invention
The length of machine, and at U-shaped structure, to increase the length of air cavity 21 in reaching in a limited space.
Further, air cavity 21 slowly increases by 211 side sectional area of aditus laryngis, on 212 side width of opening
Increase by exponential type, slowly increases in height or constant.The size of the length of horn and 212 areas that are open, substantial connection
The sound property of horn.Horn shape, close to the side of aditus laryngis 211, in the elongated appearance being slowly unfolded；By the part of opening,
Sectional area quickly increases, so that opening area increases as far as possible, further decreases the low-limit frequency of playable sound, or only exist
It makes and changes on width, do not influence the comfort held.
Further, air cavity 21 is set to the one side of shell 2 Yu 1 back contact of mobile phone, and air cavity 21
Height is less than the thickness of shell 2, and opening 212 is set to the separate one side at 1 back contact of mobile phone on shell 2.Air cavity
21 may be configured as groove-like, and by being bonded with 1 back of mobile phone to form horn structure, make mobile phone shell back smooth and beautiful appearance.
Separately have, air cavity 21 is set to the separate one side at 1 back contact of mobile phone on shell 2, and by tubulose knot
It is configured to.Air cavity 21 is arranged at 2 back of shell, becomes horn tubulose stack shell, this configuration reduces want to 2 thickness of shell
It asks, increases the heat dissipation effect of mobile phone, and reduce materials cost.
Further, tubular structure tube wall face far from 2 back side of shell at opening 212 is tilted relative to 2 back side of shell
Setting.And mobile phone 1 and placement mobile phone 1 of the opening 212 far from 1 edge of mobile phone, when mobile phone 1 is placed on the table, on the outside of opening 212
Face will constitute the extension of horn opening size, which is equivalent to bigger horn, can further promote sound quality and volume.
