Sound-producing device module provided by the utility model can avoid sound in channel of speaking since reflection direction is consistent
And generate noise.Furthermore it is possible to promote the sound quality of sound-producing device module, avoid being distorted.
A kind of sound-producing device module as shown in Figure 1, including module casing 1.There is ante-chamber 11 in module casing 1 and speak
Channel 12.Outlet sound mouth 13 is provided on module casing.Outlet sound mouth 13 is connected to by channel 12 of speaking with ante-chamber 11 so that ante-chamber 11
Interior sound can be transferred to by outlet sound mouth 13 outside sound-producing device module.Speak channel 12 inner wall surface 14 it is all or part of
With rough shape so that sound is transferred to by ante-chamber 11 when speaking in channel 12, and the sound wave of sound is in channel of speaking
Irregular slow fire is formed in inner wall surface 14 in 12；Relative to smooth inner wall surface 14, direction can not be formed with respect to one
The sound wave of cause reflects, and after relatively uniform sound wave multiple reflections are overlapped mutually enhancing, sound wave will form noise in the cavity, make
At distortion, rough inner wall surface 14 can not form the relatively uniform reflection in direction, can also avoid the shape of noise
At the sound quality of promotion sound-producing device module avoids being distorted.
Optionally, speak channel 12 inner wall surface 14 can pass through later stage roughening treatment, typically module casing is in life
Mechanization processing when production processing so that its inner wall surface 14 is uneven.The roughening treatment can be electric spark processing, erosion
It carves processing or a kind of mode in surface spraying processing or various ways is combined, the inner wall surface 14 in channel 12 of speaking is molded
Afterwards, it is handled so that its is uneven.For example, shown in Fig. 2 and Fig. 3, it is molding smooth by modes such as injection moldings
Inner wall surface 14, after electric spark roughening treatment, that rough spark line 2 for being formed in inner wall surface 14.
Optionally, the rough shape, can also be to pass through preset die so that the inner wall table in channel 12 of speaking
Rough shape is integrally formed when module casing 1 is molded on face 14, and also there is no need to the roughening treatment in later stage, Neng Goujian
Change the processing technology of sound-producing device module.For example, in a mold, the position spoken corresponding to the inner wall surface 14 in channel 12, if
Set rule or some specific three-dimensional shapes such as irregular sags and crests, diamond block, can also be some random shapes
Shape, the application are not intended to limit this, enable to the inner wall surface 14 in the channel 12 of speaking by injection molding uneven i.e.
It can.
Optionally, in other implementations, the indent of matrix form or/and outer can be formed as in inner wall surface 14
Convex form uses convenient for design, substantially uniform sound quality can be obtained in multiple batches of sound-producing device module, difference will not mistake
Greatly.Using preset die, when manufacturing this sound-producing device module by integrated injection molding, the design and manufacture of mold are also allowed for.
Optionally, module casing 1 may include several shells, several described shells can be combined into module casing 1
It is some or all.Channel 12 of speaking is enclosed by several shells, easy to process can be assembled；It also allows for going out
When the inner wall surface 14 in sound channel 12 carries out roughening treatment, inner wall surface 14 can be directly exposed to the external world, directly carried out thick
Change is handled.For example, as illustrated in fig. 1-3, module casing 1 includes first shell 15 and second shell 16, channel 12 of speaking
Inner wall surface 14 is divided to for two parts, is located in first shell 15 and second shell 16, first shell 15 and second shell
After 16 fasten, it will be able to form a complete channel 12 of speaking；First shell 15 and second shell 16, which also fasten, constitutes portion
Divide module casing 1.It will be understood by those skilled in the art that in other implementations, inner wall surface 14 can also distinguish position
In on all shells of composition whole module casing 1, by assembling, complete module casing 1 can be formed and channel 12 of speaking.
In some other specific implementation modes, class origin channel 12 can also be provided only on several shells for constituting module casing 1
In one in, be also that by the utility model, the utility model is not intended to limit this.
Optionally, module casing 1 includes several shells.Outlet sound mouth 13 is disposed therein on a shell or outlet sound mouth
13 are enclosed by several shells.For example, as illustrated in fig. 1-3, module casing 1 includes first shell 15 and second shell
Body 16, outlet sound mouth 13 are arranged in first shell 15；In other implementations, can also be that outlet sound mouth 13 is divided to it is two
Point, it is separately positioned in first shell 15 and second shell 16, by the fastening of first shell 15 and second shell 16, is formed out
Sound mouth 13, the utility model is not intended to limit this.
Optionally, as shown in Figure 1, the sound-producing device module further includes sound-producing device monomer 3, for working
When, generate sound.There is accommodating chamber, for accommodating sound-producing device monomer 3 in module casing 1.The setting of sound-producing device monomer 3 is being held
It receives intracavitary, accommodating chamber is divided into ante-chamber 11 and back cavity 17, ante-chamber 11 is adjusted for transmitting sound, back cavity 17 for improving sound
Save sound quality.Further, sound-producing device monomer 3 includes vibrating diaphragm 31, and sound, ante-chamber 11 are generated by the vibration of vibrating diaphragm 31
In the side of vibrating diaphragm 31, back cavity 17 is located at the opposite other side of vibrating diaphragm 31.
