【Specific embodiment】

In order to make the purpose of the utility model, technical solutions and advantages more clearly understood, below in conjunction with attached drawing and implementation Example, the present invention is further described in detail.It should be appreciated that specific embodiment described herein is only explaining this Utility model is not used to limit the utility model.But the utility model can be realized in many different forms, and It is not limited to embodiment described herein.On the contrary, the purpose for providing these embodiments is made in the disclosure to the utility model The understanding of appearance more thorough and comprehensive.

Unless otherwise defined, all technical and scientific terms practical this paper are led with belonging to the technology of the utility model The normally understood meaning of technical staff in domain is identical.It is only in the term used in the description of the utility model herein The purpose of description specific embodiment, it is not intended that limitation the utility model.

Please refer to Fig. 1 and Fig. 2, a kind of structure diagram of the specific embodiment of Mobile phone loudspeaker of the utility model. The Mobile phone loudspeaker includes：Fixed part 10 and the portion 20 that amplifies.

Fixed part 10 is fixed on mobile phone back, can be mobile phone protecting case or mobile phone back splint battery in practice. Its concrete structure is familiar to those skilled in the art, and this will not be repeated here.

10 back of fixed part is fixed in the portion 20 that amplifies.The back of the fixed part 10 i.e. fixed part 10 is backwards to the one of mobile phone Face.

Continuing with reference to Fig. 3, it is provided in the portion 20 that amplifies：Amplify chamber 22.The chamber 22 that amplifies is is set to the portion that amplifies A sound chamber inside 20.One end of the sound chamber is the sound intake end 221 of the chamber 22 that amplifies, and the other end of the sound chamber is the chamber that amplifies 22 go out sound end 222.The sound intake end 221 is set to position corresponding with Mobile phone horn；This goes out sound end 222 and is set to far from the hand The position of machine loudspeaker.The Mobile phone horn by vibrating diaphragm by conduct vibrations to air, the air of the vibration enters from the sound intake end 221 The sound chamber, through vibrations and sympathetic response after, from this go out sound end 222 from the sound chamber out, achieve the effect that amplify.

Optimization, which is greater than the sound intake end aperture, to reach amplifying effect.More think to optimize , sound chamber one compression unit of formation near the input end 222, the diameter aperture of the compression unit 223 is less than the sound intake end aperture； As a result, to achieve the effect that preferably to expand sound field.

Optimization, this amplify chamber 22 the portion of amplifying 20 in the plane be projected as bugle shape.

Optimization, this goes out sound end 222 and is set to one side farthest apart from loudspeaker in the portion 20 that amplifies.So that this amplifies The length of chamber 22 is maximum, increases air compressed path and increases sound propagation time.Sound can be improved by increasing air compressed path Pressure, increase propagation time can allow people's perceived sounds to be released from farther place, increase the spatial impression of sound.

Optimization, increased battery module 23 is used to power to mobile phone in this amplifies portion 20.The then Mobile phone loudspeaker The multiple effect that can be charged but also amplify can be reached.

Optionally, the fixed part 10 of the public address set, can be mobile phone protecting case or mobile phone back splint battery, So that the public address set not only has amplifying effect, it is also equipped with protection mobile phone or the functions such as charges the phone.

As shown in figure 4, optimization, which can set two to go out sound end 222, that is, the sound chamber forms double end number The shape at angle.For the Mobile phone horn of monophonic, by the diffusion sound field of double end bugle, the effect of two-channel can be generated, is carried Rise the three-dimensional sense of sound.Optimization, the two go out the both sides that sound end 222 is set to the portion 20 that amplifies, and go out sound end to expand two 222 distance increases the separating degree of left and right acoustic channels, further promotes the three-dimensional sense of sound.

As shown in figure 5, optimization, it is additionally provided in the portion 20 that amplifies：The sealing element 21.Sealing element 21 is set to the portion of amplifying 20 positions corresponding with the loudspeaker of mobile phone.The sealing element 21 can be a rubber cushion, such as：Silicagel pad.The sealing element 21 is annular. When the Mobile phone loudspeaker is fixed on corresponding mobile phone, which is pressed on the loudspeaker surrounding of the mobile phone.So as to ensure The sound sent out in loudspeaker is neither blocked by sealing element 21, but will not be spread out from the portion of amplifying 20 so that amplify portion 20 Amplifying effect it is more preferable.

A kind of specific embodiment of Mobile phone loudspeaker of the utility model, using on Mobile phone horn external one carry The portion 20 that amplifies of sound chamber so that the sound sent out in Mobile phone horn is vibrated after the sound chamber and expanded, so as to reach the effect to amplify Fruit.

Above-mentioned specific embodiment illustrates but is not intended to limit the utility model, and those skilled in the art can be in claim In the range of design it is multiple replace example.Those skilled in the art should be appreciated that being violated no as appended Within the scope of the utility model as defined in the claims, appropriate adjustment, modification etc. can be made to specific implementation. Therefore, all according to the spirit and principles of the utility model, the arbitrary modifications and variations done are determined in the appended claims Within the scope of the utility model of justice.
