Embodiment

The present embodiment provides a kind of loudspeakers 100 with spring-piece type structure, please refer to Fig. 1-Fig. 3.100 energy of loudspeaker Improve elastic slice 140 to the signal interference of electronic equipment, and more saves material cost.

Loudspeaker 100 includes bracket 110, magnetic circuit system 120, vibrational system 130, front cover 150 and elastic slice 140.

Wherein, bracket 110 is the internal framework with accommodating space, and framework is in a ring.Bracket 110 includes opposite first Side 111 and second side 112.

Referring to figure 3., vibrational system 130 and magnetic circuit system 120 are set in the accommodating space of bracket 110, and magnetic circuit system System 120 covers at vibrational system 130.Wherein, the first side 111 of bracket 110 is arranged in magnetic circuit system 120, and the setting of front cover 150 exists Second side 112 of bracket 110, front cover 150 are connect with second side 112 of bracket 110.I.e. vibrational system 130 is arranged in magnetic circuit system Between system 120 and front cover 150.

It should be noted that front cover 150 is also frame structure, front cover 150 is all projected on second side 112 of bracket 110.

Vibrational system 130 include voice coil 131 and vibrating diaphragm 132, in a ring, vibrating diaphragm 132 is plate-like for voice coil 131, voice coil 131 with Elastic slice 140 connects.Wherein, external electric energy is imported voice coil 131 for being electrically connected with the external circuit board by elastic slice 140.Vibrating diaphragm 132 are arranged in the ring-shaped inner part of voice coil 131, and vibrating diaphragm 132 is connect with magnetic circuit system 120.

Wherein magnetic circuit system 120 has magnetic gap towards the side of vibrational system 130, and voice coil 131 is set to the magnetic gap It is interior.

The first side 111 of bracket 110 is arranged in elastic slice 140, and the both ends of bracket 110 are both provided with elastic slice 140.

Fig. 1 and Fig. 4 are please referred to, elastic slice 140 includes the construction section 141 and stretch section 142 of connection, and construction section 141 is embedded solid It connecting due to 110 inside of bracket and with voice coil 131, stretch section 142 extends along the width direction of bracket 110, and stretch section 142 Length is less than the width of bracket 110.Wherein, voice coil 131 can be with external circuit board electrical connection by elastic slice 140.

Voice coil 131 is electrically connected by elastic slice 140 with the external circuit board, and external electric energy can be passed to voice coil 131, voice coil 131 Access electric current vibrates in the magnetic field that magnetic circuit system 120 generates, and the vibration of vibrating diaphragm 132 is driven to make a sound.

Since existing common 140 specification of elastic slice is all longer, usually it is longer than the width of bracket 110, due to elastic slice 140 For metal, metal will affect antenna performance.And long chip elastic slice 140 will increase buckle to limit, buckle-type increases elastic slice 140 production workload, is unfavorable for producing.

Since the elastic slice 140 of the present embodiment has construction section 141 and stretch section 142, it is embedded by construction section 141 in bracket Then 140 entirety of elastic slice can be preferably fixed on bracket 110 inside 110.In addition, the length due to stretch section 142 is less than branch The length of the width of frame 110, elastic slice 140 is shorter, improves elastic slice 140 to the signal interference of electronic equipment, and save material Cost.Also, the loudspeaker 100 of the present embodiment is not provided with buckle structure, and production is got up simpler.

Further, the length of stretch section 142 is the 1/3~1/2 of 110 width of bracket.Wherein, the length of stretch section 142 For 5~5.5mm.

In addition, referring to figure 4., in the present embodiment, stretch section 142 includes extension 142a and hook portion 142b, extension The both ends of 142a are connect with construction section 141 and hook portion 142b respectively.

Wherein, the surface of the elongated plate of extension 142a, extension 142a and bracket 110 is in 10-45 ° of angle.

Due to having certain angle between extension 142a and bracket 110, then have between extension 142a and bracket 110 There is certain activity space.In addition, since elastic slice 140 has elasticity, then extension 142a can be according to the connection of the external circuit board Situation adjusts the distance between bracket 110.

Optionally, in this embodiment, the surface of extension 142a and bracket 110 is in 15-30 ° of angle.

Further, hook portion 142b is arc-shaped, and hook portion 142b is directed away from the direction protrusion of bracket 110.Hook portion 142b End on the extended line of extension 142a.

Wherein, hook portion 142b with the external circuit board for being electrically connected.Test discovery is studied through inventor, hook portion 142b is in this way Set-up mode, can preferably with the external circuit board realization be electrically connected.

The working principle of the loudspeaker 100 of the present embodiment：

Above description is merely a prefered embodiment of the utility model, is not intended to limit the utility model, for For those skilled in the art, various modifications and changes may be made to the present invention.All spirit and original in the utility model Within then, any modification, equivalent replacement, improvement and so on be should be included within the scope of protection of this utility model.
