The utility model provides a kind of loudspeaker mould group, which includes: module casing, loudspeaker assembly 20, conduct piece 30 and conductive magnetic yoke 40, the module casing has the first face and the second face being parallel to each other in flat, first face and The space for accommodating the loudspeaker assembly 20 is formed between second face, the loudspeaker assembly 20 is configured as will be electric Signal is converted to acoustical signal.
It include the conductive magnetic yoke 40 on first face in module casing, the conduct piece 30 is arranged in the conductive magnetic yoke Between 40 and second face, the conduct piece 30 connects the conductive magnetic yoke 30 with the module casing.
Particularly, in loudspeaker mould group, conductive magnetic yoke 40 include be used to form first part's conductive magnetic yoke of magnetic circuit system with And extend to second part conductive magnetic yoke outside the loudspeaker assembly.The conductive magnetic yoke be connected with conduct piece in the present embodiment, refers to Be the second part conductive magnetic yoke outside the loudspeaker assembly.
As shown in Figure 1, the conduct piece 30 is arranged between the conductive magnetic yoke 40 and the module casing, i.e. conductive magnetic yoke 40 With the fixed space for being formed with receiving conduct piece 30 inside module casing, conduct piece 30 is arranged in module casing, this knot Structure mode advantageously reduces the integral thickness of loudspeaker mould group, makes full use of the inner space of loudspeaker mould group;Meanwhile compared to External anti-static part, built-in conduct piece 30 effectively reduce the risk of shaking, ensure that good ground connection.Electrostatic energy from Module internal exports rapidly, is conducive to the reliability and service life that improve electronic equipment.
It will be appreciated by those skilled in the art that, conduct piece 30 can be metal clips, flexible circuit board, spring etc., this Type, form of embodiment conduct piece etc. are with no restrictions.
In in a zigzag, one end of the conduct piece 30 and the conductive magnetic yoke 40 are connected conduct piece 30 shown in the present embodiment, The other end of the conduct piece 30 is connect with the module casing.In this way, what loudspeaker module internal can be full of by conduct piece 30 A large amount of charges export loudspeaker by conductive magnetic yoke or module casing, to achieve the purpose that antistatic.
Loudspeaker modular structure provided in this embodiment, by loudspeaker module internal conductive magnetic yoke and module casing it Between conduct piece is set, conduct piece is connected with conductive magnetic yoke and module casing, and the charge of loudspeaker module internal is exported.In this way, Both the integrally-built compactedness of mould group had been improved, external electrostatic prevention structure is eliminated, has avoided external electrostatic prevention structure because of external force And it fails;Also improve the stability and service life of electronic equipment entirety.
Further, the conduct piece 30 includes: first connecting portion 31, second connecting portion 33 and elasticity arm 32, described 32 both ends of elasticity arm, which each extend over, is provided with first connecting portion 31 and second connecting portion 33, constitutes the conduct piece 30.Such as Fig. 2 institute Show, first connecting portion 31 is connect with the conductive magnetic yoke in loudspeaker mould group on conduct piece 30, and second connecting portion 33 and module casing connect It connects, in this way, a large amount of charges being full of in conductive magnetic yoke can be transferred on module casing by conduct piece 30, to be grounded antistatic Effect.
A kind of optional shape of conduct piece 30 is shown in Fig. 2, the present embodiment does not do specific requirement to the shape of conduct piece, The shape of suitable conduct piece can be selected according to the interior spatial structure of conductive magnetic yoke and module casing.Those skilled in the art can With understanding, in order to reach preferable anti-static effect, the material of conduct piece preferably selects the good metal of electric conductivity, example Such as, gold, silver, copper etc..

Optionally, the surface of the conductive contact 311 has Gold plated Layer, to enhance between conductive magnetic yoke 40 and conduct piece 30 Electric conductivity.On the surface of conductive contact 311, setting Gold plated Layer is a kind of optional scheme, also may be selected that other electric conductivity are electroplated The good material of energy, the present embodiment are without limitation.
In the present embodiment, the elasticity arm 32, first connecting portion 31 and second connecting portion 33 are integrally formed, and in this way can While guaranteeing conduct piece electric conductivity and structural stability, moreover it is possible to simplify installation.
As shown in Fig. 2, the position that the first connecting portion 31 is connect with the elasticity arm 32 is formed with bending part 321.I.e. First connecting portion 31 is then flat by bending part 321 again to when 32 transition of elasticity arm, being first transitioned into the lesser bending part 321 of corner Cunning transits to elasticity arm 32.In this way, first connecting portion on the one hand can be reduced to when elasticity arm transition, since connection corner is larger Caused problem of stress concentration;On the other hand, the bending part between first connecting portion and elasticity arm is also avoided that first Interconnecting piece jacks up upwards under the action of elasticity arm, by conductive magnetic yoke.To improve conduct piece structure in loudspeaker mould group Stability.
In conduct piece provided in this embodiment, between the elasticity arm 32 and first connecting portion 31 and second connecting portion 33 Bending angle is obtuse angle.Such design can reduce conduct piece because bending generates biggish screen resilience to a certain extent.
In addition, module casing provided in this embodiment includes: mould group upper casing 11, shell 12 and rear cover 13 in mould group.It is described It is provided with the conductive magnetic yoke 40 on rear cover 13, is connected with the conduct piece between the conductive magnetic yoke 40 and the mould group upper casing 11 30.The loudspeaker assembly 20 is arranged in the mould group in shell 12, and the rear cover 13 is fixedly connected with shell 12 in the mould group.
Particularly, the rear cover is made of metal material, has metal connecting piece on the mould group upper casing 11 of non-metallic material, A large amount of charges of module internal can be exported by the both ends of conduct piece in this way.
On the basis of the above embodiments, the first connecting portion 31 of the conduct piece 30 and the conductive magnetic yoke 40 are connected, institute The second connecting portion 33 for stating conduct piece 30 is connect with the mould group upper casing 11.The a large amount of charges being full of in conductive magnetic yoke 40 are logical mostly conductive Part 30 is transferred on mould group upper casing 11, to be grounded the effect of antistatic.
Optionally, pad 111 is provided on the mould group upper casing 11, the pad 111 is located at the mould group upper casing 11 Edge, the second connecting portion 33 are electrically connected with the mould group upper casing 11 by pad 111.
