[detailed description of the invention]
The utility model is described in further detail with embodiment below in conjunction with the accompanying drawings.
Please refer to Fig. 1 to Fig. 3, wherein, Fig. 1 is the axonometric chart of this utility model loudspeaker enclosure;Fig. 2 is that this practicality is new The stereochemical structure exploded view of type loudspeaker enclosure;Fig. 3 is the sectional view of line A-A along Fig. 1.Described loudspeaker enclosure 100 includes housing 1, sound passage 2, the loudspeaker monomer 3 being contained in described housing 1, sound absorption part 5, flexible PCB 8 and dust-proof seal ring 9 are led.
Described housing 1 includes upper shell 11 and assembles the lower house 13 forming receiving space with described upper shell 11.Described Loudspeaker monomer 3 includes that the vibrating diaphragm 31 for vibration sounding, described upper shell 11 and described vibrating diaphragm 31 interval arrange sound before formation Chamber 4.Described flexible PCB 8 provides electric energy for described loudspeaker monomer 3.Described sound passage 2 of leading is for connecting the described front operatic tunes 4 And the external world, the sound making described vibrating diaphragm 31 send reaches in outside air.The described front operatic tunes 4 and described lead the common structure of sound passage 2 Become the ante-chamber 7 of described loudspeaker enclosure 100.Described lead sound passage 2 connect the external world one end open be outlet sound mouth 21, described outlet sound mouth 21 are arranged on described housing 1, concrete, are arranged at described upper shell 11, and described dust-proof seal ring 9 is located at described outlet sound mouth 21 Place.The space surrounded between described vibrating diaphragm 31, described upper shell 11 and described lower house 13 is the back cavity relative with described ante-chamber 7 6。
On described upper shell 11, the position of corresponding described ante-chamber 7 is provided with the described ante-chamber of connection 7 running through upper shell 11 with outer The leak holes 111 on boundary, it is alternatively that, described leak holes 111 may be located at the position of the corresponding described front operatic tunes 4 on described upper shell 11 Put or lead described in correspondence the position of sound passage 2.
Described loudspeaker enclosure 100 also includes the sound absorption part 5 being located on described upper shell 11 and covering described leak holes 111, Sound absorption part 5 is arranged at the optional position in any side of described leak holes 111 or described leak holes 111, described upper shell 11 are provided with groove 113 at described leak holes 111, and described sound absorption part 5 is contained in described groove 113, and described groove 113 is arranged In described leak holes 111 side, its size matches with the size of described sound absorption part 5, and described sound absorption part 5 is preferably Air Filter Cloth, dust-proof screen cloth is preferably by mainly having polyester and terylene to utilize high accuracy loom to work out by preset ratio.
Owing to described ante-chamber 7 resonance of described loudspeaker enclosure 100 can amplify radio-frequency component and high-frequency noise, reduce sound sound Matter.Described leak holes 111 destroys the integrity of described ante-chamber 7 volume, reduces the amplification effect of the resonance of described ante-chamber 7, Thus improve the distortion of intermediate frequency sound wave, reduce radio-frequency component and high-frequency noise.Meanwhile, described leak holes 111 also slow down institute State the air pressure level in ante-chamber 7, described lead sound passage 2 in have bigger resistance or damping time, reduce described ante-chamber 7 endogenous cause of ill empty Gas is non-linear and causes the sound of output the amplitude of fluctuation occur, improves the stablizing of sound of described loudspeaker enclosure 100 output Degree.Additionally, the wavelength of low-frequency sound wave is longer in described loudspeaker enclosure 100, described the leak holes 111 less and described outlet sound mouth of diameter 21 is bigger, and low-frequency sound is easy to go out from described outlet sound mouth 21, and the most described leak holes 111 is on the impact of low-frequency sound wave relatively Little, mainly for the tonequality improving intermediate frequency and high frequency sound wave.
Sound absorption part 5 has preferable acoustically effective to from leak holes 111 higher hamonic wave out, it is possible to reduce leak holes The crosstalk of 111 pairs of outlet sound mouths 21.Furthermore, it is possible to leak holes 111 size is adjusted by sound absorption part 5, reduce leakage The requirement of hole 111 size, reduces the difficulty of processing making described leak holes 111.
Described dust-proof seal ring 9 is arranged between described outlet sound mouth 21 and the external world, prevents the dust in outside air and different The thing described outlet sound mouth 21 of entrance leads sound passage 2 described in blocking, and affects the sounding effect of described loudspeaker enclosure 100.
Refer to Fig. 4, have the loudspeaker enclosure of leak holes with other without the mistake of the loudspeaker enclosure of leak holes for this utility model True data experiment curv figure.Wherein curve I is the loudspeaker enclosure distortion data experiment curv without leak holes 111, and curve II is for raising Sound device case has the distortion data experiment curv of leak holes 111.Can be seen that the intermediate frequency distortion of the loudspeaker enclosure with leak holes 111 Degree is well below the loudspeaker enclosure not having leak holes 111.
Refer to Fig. 5, have the loudspeaker enclosure of leak holes with other without the frequency of the loudspeaker enclosure of leak holes for this utility model Rate response data experiment curv figure.Wherein curve I is the loudspeaker enclosure frequency response data experiment curv without leak holes 111, bent Line II has the frequency response measurement curve of leak holes 111 for loudspeaker enclosure.Can be seen that have the loudspeaker enclosure of leak holes 111 with Not there is the loudspeaker enclosure of leak holes 111 and compare that its high-frequency resonant is more weak and resonance peak is lower, the sound sense of hearing therefore sent More preferably.It can also be seen that the effective band not impact that with or without leak holes 111, loudspeaker enclosure is sent sound simultaneously.
Refer to Fig. 6, have for this utility model the loudspeaker enclosure of leak holes and sound absorption part to have leak holes without sound absorption with other The higher hamonic wave DATA REASONING curve chart of the loudspeaker enclosure of part.Wherein curve I has leak holes 111 without sound absorption part 5 for loudspeaker enclosure Higher hamonic wave DATA REASONING curve, curve II has leak holes 111 and the higher hamonic wave DATA REASONING of sound absorption part 5 for loudspeaker enclosure Curve.Can be seen that the loudspeaker enclosure with leak holes 111 and sound absorption part 5 and the loudspeaker enclosure only with leak holes 111 Comparing its higher hamonic wave lower, the sound timbre of output is higher.
The beneficial effects of the utility model are: add the leak holes for being in communication with the outside by ante-chamber 7 within the case 1 111, to destroy the integrity of described ante-chamber 7 volume, reduce described ante-chamber 7 to radio-frequency component and the amplification of high-frequency noise, Slow down the air pressure level in described ante-chamber 7 simultaneously, when outlet sound mouth 21 has bigger resistance or damping, reduce described ante-chamber 7 Endogenous cause of ill air nonlinearity and cause output sound occur fluctuation amplitude, improve described loudspeaker enclosure 100 output sound Degree of stability;Sound absorption part 5 is set in order to covering described leak holes 111 to absorb higher hamonic wave, it is to avoid described leak holes 111 is right The crosstalk of described outlet sound mouth 21, it is ensured that described loudspeaker enclosure 100 exports the high tone quality of sound, can be by sound absorption part 5 to letting out Dew hole 111 size is adjusted, and reduces the requirement to leak holes 111 size, reduces the processing making described leak holes 111 Difficulty, simplifies the processing technology of described loudspeaker enclosure 100.
Above-described is only embodiment of the present utility model, it should be noted here that for the ordinary skill of this area For personnel, on the premise of creating design without departing from this utility model, it is also possible to make improvement, but these belong to this practicality Novel protection domain.
