The acoustic aperture 7 Size ladder shape going out acoustic aperture to projection section 52 that goes out on Part I housing 51 can also be reduced design, so also can guarantee that in projection section 52 go out the maximum size going out acoustic aperture of acoustic aperture mesoporous than on Part I housing 51 go out in acoustic aperture 7 smallest size of go out acoustic aperture size little, such as: as the size going out acoustic aperture 7 on Part I housing 51 is disposed as 1.2mm, the hole dimension of speaking in projection section 52 is disposed as 1.0mm.
If the projection section 52 in Fig. 4 a only arranges decoration hole, decoration hole size can also select any number between 0.4mm to 0.6mm, the design that the aperture size to the decoration hole projection section 52 going out acoustic aperture 7 from Part I housing 51 is sequentially reduced can be selected, such as, the size going out acoustic aperture 7 on Part I housing 51 sets gradually as 1.2mm, 0.9mm, 0.8mm, decoration hole size in projection section 52 sets gradually as 0.6mm, 0.5mm, 0.4mm, certainly the design of the stepped reduction of aperture size to the decoration hole projection section 52 going out acoustic aperture 7 from Part I housing 51 can also be selected, as the size going out acoustic aperture 7 on Part I housing 51 is disposed as 1.2mm, decoration hole size in projection section 52 is disposed as 0.5mm.
If the projection section 52 in Fig. 4 a includes decoration hole and goes out acoustic aperture simultaneously, wherein, projection section 52 speaks hole dimension can for any number between 0.8mm to 1.5mm, and in projection section 52 go out the maximum size going out acoustic aperture of acoustic aperture mesoporous size than on Part I housing 51 go out in acoustic aperture 7 smallest size of go out acoustic aperture size little, decoration hole size can select any value between 0.4mm to 0.6mm, the design that the aperture size going out acoustic aperture and decoration hole projection section 52 going out acoustic aperture 7 from Part I housing 51 is sequentially reduced can be selected, such as, the size going out acoustic aperture 7 on Part I housing 51 sets gradually as 1.2mm, 1.0mm, hole dimension of speaking in projection section 52 sets gradually as 0.9mm, 0.8mm, decoration hole size in projection section 52 sets gradually as 0.6mm, 0.5mm, certainly the design to the stepped reduction of the aperture size going out acoustic aperture and decoration hole projection section 52 going out acoustic aperture 7 from Part I housing 51 can also be selected, as the size going out acoustic aperture 7 on Part I housing 51 is disposed as 1.2mm, hole dimension of speaking in projection section 52 is disposed as 0.8mm, decoration hole size in projection section 52 is disposed as 0.5mm.
Certainly, in actual applications, the maximum size in aperture in ensureing the hole arranged in projection section 52 than on Part I housing 51 go out in acoustic aperture 7 smallest size of go out acoustic aperture the little premise of size under, can not also be sequentially reduced according to the size going out the acoustic aperture 7 hole to projection section 52 on Part I housing 51 or stepped reduction is arranged, namely can by Part I housing 51 multiple go out acoustic aperture 7 not according to the sequence of positions going out acoustic aperture, any number in being arranged between 0.8mm to 1.5mm, same, can also by the hole of the setting in projection section 52 not according to the sequence of positions numerical value that to be arranged between 0.8mm to 1.5mm different, such as, when on Part I housing 51 go out acoustic aperture 7 have three time, when the hole of the setting in projection section 52 also has three, 1mm can be set in three apertures going out acoustic aperture on Part I housing 51, 0.9mm, 1.1mm, three apertures going out acoustic aperture in projection section 52 are set to 0.8mm, 0.6mm, 0.8mm.
In the present embodiment, concrete, only include decoration hole with the projection section 52 in Fig. 4 a, and the pore size going out the acoustic aperture 7 decoration hole to projection section 52 on Part I housing 51 is sequentially reduced and is designed as example.
In specific implementation process, continuing with continuing to use above-mentioned example, in actual applications, Part II housing adjacent with Part I housing 51 on the housing 5 of the intelligent domestic appliance controller, can also be as shown in Figure 4 b, refer specifically on housing 5 adjacent with Part I housing 51, and remove the partial shell 52 outside the front sound chamber 61 direction of vibration along vibrating diaphragm 41 projection section on housing, such as, when the vibrating diaphragm 41 in speaker 4 only includes the vibrating diaphragm face for vibration sounding, front sound chamber 61 along projection section on housing of the direction of vibration of vibrating diaphragm and vibrating diaphragm along the size of the projection section of its direction of vibration be consistent, so, partial shell 52 in Fig. 4 b just goes forward the sound chamber direction of vibration along vibrating diaphragm projection section on housing 5 or vibrating diaphragm 41 along the partial shell outside the projection section of its direction of vibration for housing 5
Concrete, when vibrating diaphragm 41 in speaker 4 only includes the vibrating diaphragm face for vibration sounding, front sound chamber 61 along projection section on housing of the direction of vibration of vibrating diaphragm 41 and vibrating diaphragm along the size of the projection section of its direction of vibration be consistent, so, partial shell 52 in Fig. 4 b just goes forward the sound chamber direction of vibration along vibrating diaphragm projection section on housing or vibrating diaphragm along the partial shell outside the projection section of its direction of vibration for housing 5, same, can be according to actual needs, whether partial shell 52 in fig. 4b arranges out acoustic aperture, whether function is set and is different from out other functional holes of acoustic aperture, as selected only to arrange some decoration hole in partial shell 52, as can be selected to arrange decoration hole in partial shell 52 and go out acoustic aperture simultaneously, or go out acoustic aperture as can be only arranged some in partial shell 52, same, when being provided with out acoustic aperture in partial shell 52, in partial shell 52 go out the maximum size going out acoustic aperture of acoustic aperture mesoporous than on Part I housing 51 to go out acoustic aperture mesoporous smallest size of little, when being provided with decoration hole in partial shell 52, the decoration hole size in partial shell 52 can be any value between above-mentioned 0.4mm to 0.6mm, at this just not repeated description.
In specific implementation process, continuing with continuing to use above-mentioned example, in actual applications, Part II housing adjacent with Part I housing 51 on the housing 5 of the intelligent domestic appliance controller can also be adjacent with Part I housing 51 on housing 5 simultaneously, and front sound chamber 61 is along projection section on housing of the direction of vibration of vibrating diaphragm, and housing 5 removes the part outside the front sound chamber 61 direction of vibration along vibrating diaphragm projection section on housing, such as, when the vibrating diaphragm 41 in speaker 4 include the vibrating diaphragm face for vibration sounding and be arranged on around vibrating diaphragm face edge time, on housing 5 adjacent with Part I housing 51, and front sound chamber 61 along projection section on housing of the direction of vibration of vibrating diaphragm just for the projection on housing 5 of the edge around vibrating diaphragm face, referred to herein as edge projection section.
Before housing 5 removes sound chamber 61 along the part outside projection section on housing of the direction of vibration of vibrating diaphragm just for problem removes the residue housing parts outside above-mentioned edge projection section and Part I housing, same, can be according to actual needs, the Part II housing including above-mentioned edge projection section and residue housing parts chooses whether to arrange out acoustic aperture, whether function is set and is different from out other functional holes of acoustic aperture, as selected only to arrange some decoration hole in Part II housing, as can be selected to arrange decoration hole in Part II housing and go out acoustic aperture simultaneously, or go out acoustic aperture as can be only arranged some in Part II housing, same, when being provided with out acoustic aperture at Part II housing, on Part II housing go out the maximum size going out acoustic aperture of acoustic aperture mesoporous than on Part I housing 51 to go out acoustic aperture mesoporous smallest size of little, when being provided with decoration hole at Part II housing, the decoration hole size of Part II housing can be any value between above-mentioned 0.4mm to 0.6mm, at this just not repeated description.
In specific implementation process, continuing with continuing to use above-mentioned example, in actual applications, the volume in front sound chamber can be dimensioned to any number between the 13% to 15% of whole sound cavity volume, because, when shared by the volume size in current sound chamber, the ratio of whole sound cavity volume is lower than 13%, the high-frequency effect that can make the sound that speaker sends is very poor, if the ratio of whole sound cavity volume is more than 15% shared by the volume size in front sound chamber, the low-frequency effect that can make again the sound that speaker sends is deteriorated, and ratio is too high, also the high frequency that can make the sound that speaker sends is too sharp-pointed.
So, the volume in front sound chamber is dimensioned between the 13% to 15% of whole sound chamber cavity, high-frequency effect and the low-frequency effect of the sound that speaker sends can be ensured simultaneously, such as, when the size in the sound chamber in Fig. 2 is specially 25mm × 16.4mm × 9.2mm, the size in front sound chamber 61 can be specially 12.2mm × 8.2mm × 4.5mm, and before so, the volume in sound chamber 61 is just for the 12% of the volume of whole sound chamber cavity.
Certainly, in actual applications, except the volume size in front sound chamber being arranged on except the numerical value between the 13% to 15% of whole sound chamber cavity, can also by front sound chamber along the distance in the direction of the diaphragm oscillations of speaker be set to whole sound chamber along the direction of the diaphragm oscillations of speaker distance 25% to 50% between, so also by the tonequality being beneficial to the sound that the speaker improved in sound chamber sends, concrete refer to Fig. 5, in Figure 5, front sound chamber is b along the distance in the direction of the diaphragm oscillations of speaker, whole sound chamber is a along the distance in the direction of the diaphragm oscillations of speaker, so, when the length of distance a is 9.2mm, the length of distance b can take between 2.3mm to 4.6mm, in the present embodiment, the length of distance b is specially 4.5mm.
