Within.
The utility model proposes a kind of sounding device, which is loudspeaker monomer.
In the utility model embodiment, as shown in Figure 1 to Figure 3, the sounding device include vibrational system, magnetic circuit system and
Auxiliary system, vibrational system include combined vibrating diaphragm 21 and voice coil 22, and furthermore vibrational system may also include centring disk,
Vibrating diaphragm 21 and voice coil 22 are respectively in conjunction with centring disk.Magnetic circuit system includes conductive magnetic yoke 31, and the central location of conductive magnetic yoke 31 is equipped with
Internal magnetic circuit part, internal magnetic circuit part include centring magnet 32 and the center magnetic conductive board 33 on centring magnet 32, conductive magnetic yoke 31
In bowl-shape, there is gap, the gap is for placing voice coil 22 between peripheral wall and internal magnetic circuit part.In addition, magnetic circuit system also
It may include exterior portion, the marginal position of conductive magnetic yoke 31 is arranged in exterior portion, and exterior portion includes being set to magnetic conduction
The marginal position of yoke 31 while magnet and set on while magnet on side magnetic conductive board.Auxiliary system includes shell 10, and shell 10 is used for
Accommodate fixed vibrational system and magnetic circuit system.In addition, auxiliary system may also include front cover (not shown go out), front cover is incorporated into shell
10 top, front cover and shell 10 enclose protect-ing frame structure.Certainly, in some cases, sounding device also may not include front cover.
Specifically, the shell 10 includes:
Mounting portion 11, is formed with installation cavity 111, and vibrational system and magnetic circuit system are fixed on installation cavity 111, on mounting portion 11
Equipped with rear acoustic aperture 114；And
Cavity portion 12 afterwards are connect with mounting portion 11, and are fitted around the setting of portion 11, and rear cavity portion 12 is formed with back cavity 121, back cavity
121 are fitted around the setting of chamber 111, and rear acoustic aperture 114 is separately connected installation cavity 111 and back cavity 121, i.e., afterwards acoustic aperture 114 by magnetic gap
It is connected to back cavity 121.
The form of back cavity 121 is collectively formed in the shell 10 and complete machine of existing sounding device, due between shell 10 and complete machine
There will necessarily be installation gap, the difficulty for forming closed back cavity 121 between the two is caused to increase；Also, institute by this way
The size of the back cavity 121 of formation is generally large, causes the occupied space to complete machine excessive, is unfavorable for the reduction of package size,
It is unfavorable for rationally utilizing complete machine space.
To solve the above problems, in the utility model, by directly forming back cavity on the shell 10 of sounding device monomer
121, the formation of the back cavity 121 is only related with shell 10, without the concern for the assembly with complete machine, therefore can reduce machine assembly

Gap, so that it is more compact between the two, be conducive to reduce 10 volume of shell, realize product miniaturization.Since back cavity 121 is in
Ring-type, therefore wherein the cover board 123 of one end is also to correspond to annularly it is envisioned that lid is located at back cavity 121.The present embodiment
In, cover board 123 is plastic cover plate 123 or metal cover board 123 etc., such as cover board 123 can be mylar film, and cover board 123 is specifically with after
The welding of cavity portion 12 or bonding etc..
In addition, rear cavity portion 12 and mounting portion 11 can also be separate structure, and this two parts is connected with each other and collectively forms outer
Shell 10, for example, after the modes such as welding can be used, be bonded or snap connection between cavity portion 12 and mounting portion 11 and be fixed.
In one embodiment, installation cavity 111 includes the first hole portion 112 and the second hole portion 113, the internal diameter of the first hole portion 112
Greater than the second hole portion 113 internal diameter and collectively form stepped hole；First peripheral wall 115, which encloses, to be set to form the first hole portion 112, the second peripheral wall
116 enclose and set to form the second hole portion 113；Vibrational system is fixed on the first hole portion 112, and magnetic circuit system is fixed on the second hole portion 113, even
Wall 118 is connect equipped with rear acoustic aperture 114.In the present embodiment, since the first peripheral wall 115 and the second peripheral wall 116 are interconnected so that two
The outer peripheral surface that person is constituted is stepped, therefore is similarly also configured as the inner peripheral surface of the two ladder-like, can rationally be utilized
Shell 10, the installation for being more favorable for vibrational system and magnetic circuit system are fixed.On the other hand, since rear cavity portion 12 is disposed around second week
116 periphery of wall, and it is located at the end of the first peripheral wall 115, therefore installation cavity 111 is correspondingly arranged to be ladder-like, it can directly connect
Rear acoustic aperture 114 is opened up on wall 118, rear acoustic aperture 114 can be provided with any position in the connection wall 118, sound after capable of guaranteeing
Hole 114 can be separately connected back cavity 121 and installation cavity 111, be positioned without locating piece is additionally arranged, therefore can be convenient for rear sound
Hole 114 opens up.
Specifically, installation cavity 111 is arranged in both ends open, and vibrational system and magnetic circuit system are along the perforation side of installation cavity 111
To arrangement, and the conductive magnetic yoke 31 of magnetic circuit system seals the wherein open at one end of installation cavity 111.Optionally, the sealing of conductive magnetic yoke 31 the
The end of two hole portions 113 is arranged, and is sealed by the wherein one end of conductive magnetic yoke 31 to installation cavity 111, avoids making for sealing plate
With can not only reduce cost, can also be further reduced volume.When it is implemented, conductive magnetic yoke 31 has the opening with installation cavity 111
Hold the shape of adaptation, such as conductive magnetic yoke 31 is substantially in the cylindrical shape of open at one end, the open end of conductive magnetic yoke 31 is towards installation cavity 111
