Fig. 1 is referred to, the PA-system 100 of this utility model embodiment includes casing 102 and paster 112.

Casing 102 has been internally formed sound chamber 104, and the inwall of casing 102 is formed with groove 108 and outward leakage hole 110, groove 108 by outward leakage hole 110 and the ft connection of casing 102.

112 covering groove 108 of paster is with formation and the blow-by tube 106 of 102 ft connection of sound chamber 104 and casing.

In above-mentioned PA-system 100, due to be formed with the inwall of casing 102 groove 108 and with 102 ft connection of casing Outward leakage hole 110, and paster 112 is covered on groove 108 the leakage pipe formed outside connection sound chamber 104 and casing 102 106.Therefore the part that pipe 106 belongs to casing is revealed, so as to reduce the volume for revealing that pipe 106 takes sound chamber 104, and then is improved The tonequality of PA-system 100.For the PA-system 106 with 104 volume of phase unisonance chamber, this utility model embodiment The volume of PA-system 100 is less.

The PA-system 100 of this utility model embodiment can be applied on the small-sized electronic installation such as mobile terminal, For example on the electronic installation such as MP4, mobile phone or panel computer.For the PA-system 100 with 104 volume of phase unisonance chamber, this reality Volume with the PA-system 100 of new embodiment is less, consequently facilitating the thinner electronic installation of manufacture.

In some embodiments, include first component 102a and be connected with first component 102a second of casing 102 Part 102b；The bottom surface of first component 102a is formed with mounting groove 114, and mounting groove 114 is used to house paster 112.

Thus, in order that paster 112 is covered on mounting groove 114 the leakage pipe 106 that sealing can be formed in groove 108, The upper surface of polish mounting groove 114 is only needed, and then reduces the processing capacity of first component 102a.Meanwhile, mounting groove 114 is set The volume for revealing that pipe 106 takes sound chamber 104 can be reduced, so as to obtain more preferable acoustical quality.For manufacture is with phase unisonance The PA-system 100 of cavity volume, the volume of the PA-system 100 of this utility model embodiment are less.

In some embodiments, in order to avoid the intensity of first component 102a is weakened, first component 102a bottom surfaces can To arrange boss, groove 108 is formed on boss upper surface.

It is appreciated that in other embodiments, first component 102a is arranged also dependent on actual requirement, and is not limited to The embodiment that face discusses.

Fig. 2 and Fig. 3 is referred to, in some embodiments, form and dimension and the mounting groove 114 of paster 112 coordinate.

The size for being sized to be slightly smaller than mounting groove 114 of paster 112.Thus, paster 112 can be covered on mounting groove 114 And prevent between groove 108 and paster 112, producing gap, and then avoid gap of the sound wave between groove 108 and paster 112 from letting out Dew.

In some embodiments, depth of the thickness of paster 112 less than mounting groove 114.Thus, reveal pipe 106 will not Take the volume in sound chamber 104.

It is appreciated that in other embodiments, paster 112 and mounting groove 114 are arranged also dependent on actual requirement, and not It is limited to embodiments discussed above.

In some embodiments, paster 112 is formed with the through hole 112a connected with groove 108 so that blow-by tube 106 with Sound chamber 104 connects.

Thus, the mode simplicity of pipe 106 and sound chamber 104 is revealed in connection.

In some embodiments, through hole 112a can be U-shaped hole, or the circular hole or square of closing of one end open Shape hole.

It is appreciated that in other embodiments, through hole 112a is arranged also dependent on actual requirement, and is not limited to beg for above By embodiment.

In some embodiments, groove 108 includes first end 108a and the second end 108b positioned at length direction two ends, First end 108a is connected with through hole 112a, and the second end 108b is connected with outward leakage hole 110.

Thus, revealing the outside that pipe 106 can connect sound chamber 104 and casing 102.

It is appreciated that in other embodiments, revealing the connection side of the outside of the connection sound of pipe 106 chamber 104 and casing 102 Formula is arranged also dependent on actual requirement, and is not limited to embodiments discussed above.

In some embodiments, groove 108 is included outside first groove 108c connected with sound chamber 104 and casing 102 The 3rd groove 108e of the second groove ditch 108d and connection first groove 108c and second groove 108d of connection；

The axis of first groove 108c is substantially vertical with the axis of the 3rd groove 108e, second groove 108d and the 3rd groove 108e is substantially parallel；

Circular arc is adopted all between first groove 108c and the 3rd groove 108e and second groove 108d and the 3rd groove 108e Groove connects.

Thus, the simultaneously less noise of the sound deadening capacity that improves medium-high frequency sound wave, and then leakage pipe 106 is obtained in that preferably Bass effect.

It is appreciated that in other embodiments, the connected mode between 108 corner of shape and groove of groove 108 Can be arranged according to actual requirement, and be not limited to embodiments discussed above.

In some embodiments, each shape of cross section along its length of groove 108 and size are essentially identical.

Thus, preventing cross section mutation from causing the decay of low-frequency sound wave, it is ensured that reveal pipe 106 and be obtained in that preferable bass Effect.

It is appreciated that in other embodiments, the shape in 108 section of groove is arranged also dependent on actual requirement, and not It is limited to embodiments discussed above.

In some embodiments, the material of paster 112 is PET film.

Thus, paster 112 have preferable sealing, to avoid sound wave between groove 108 and paster 112 between clearance flow Go out and cause noise.

In some embodiments, the material of paster 112 is porous material.

Thus, paster 112 can improve the sound deadening capacity of medium-high frequency, leakage pipe 106 is made to be obtained in that preferable bass effect.

It is appreciated that in other embodiments, the material of paster 112 is arranged also dependent on actual requirement, and is not limited to Embodiments discussed above.

The electronic installation of this utility model embodiment includes the PA-system 100 of above-mentioned any one embodiment.

In some embodiments, electronic installation includes housing, and first component 102a is arranged on housing.

Thus, saving the volume of electronic installation shared by the first component 102a of PA-system 100, and then it is easy to manufacture Thinner electronic installation.

In some embodiments, electronic installation is mobile phone or panel computer.

In some embodiments, the second component 102b of casing 102 can also be produced on the housing of electronic installation.Such as This, saves the volume of electronic installation shared by the second component 102b of PA-system 100, and then is easy to manufacture thinner electronics Device.

In some embodiments, first component 102a and second component 102b be in one end open, one end closing frame Shape, the open end of first component 102a are connected to form casing 102 with Part II 102b.

In some embodiments, it is provided with for sealing first component between first component 102a and second component 102b The sealing member in gap between 102a and second component 102b, to avoid the sound wave in sound chamber 104 from first component 102a and second Clearance leakage between part 102b is gone out and causes noise, and then improves the audio quality that acoustic structure 100 plays sound.

In some embodiments, second component 102b offers out acoustic aperture 118, and speaker 116 is arranged on second component 102b is upper and is exposed to outside casing 102 by going out acoustic aperture 118.

Thus, go out acoustic aperture 118 can be so that the sound that speaker 116 sends passes to the external world of acoustic structure 100.

In example of the present utility model, the quantity for going out acoustic aperture 118 is single.It is appreciated that in other embodiments, go out The quantity of acoustic aperture 118 can be set to the other quantity such as two or more according to practical situation.Two or more go out 118 interval setting of acoustic aperture.
