Description

Mini-sound device
[technical field]
The utility model relates to a kind of microphone device, relates in particular to a kind of mini-sound device.
[background technology]
In the process of portable equipment fast developments such as mobile phone, people are more and more stronger to the functional requirement of product, for this function of Music Appreciation of mobile phone, in order to make entertainment effect stronger, the pattern that the music belt vibration occurred, thus, the also corresponding quickening of the development of mini-sound device.
The mini-sound device of correlation technique comprises basin frame, vibrating diaphragm and shell fragment, yet its shell fragment of the mini-sound device of correlation technique is a slab construction, and it comprises elasticity arm.Because elasticity arm whole in the same plane, its retractility is bad, when shell fragment fractures elasticity arm because of Oscillation Amplitude is excessive in vibration processes easily, thereby has limited the performance of the mini-sound device of correlation technique.
Therefore, being necessary to propose a kind of new mini-sound device in fact addresses the above problem.
[utility model content]
The technical problem that the utility model need solve provides a kind of Oscillation Amplitude and difficult mini-sound device that fractures of spring leaf that can increase spring leaf.
According to above-mentioned technical problem, designed a kind of mini-sound device, its objective is such realization: a kind of mini-sound device, it comprises the basin frame, places the voice coil loudspeaker voice coil in the described basin frame, the vibrating diaphragm that is fixed on the spring leaf on the described basin frame and is fixedly linked with described spring leaf.Described spring leaf is provided with main part, some along the elasticity arm of described main part bending extension and the fixed part that is extended by described elasticity arm bending.Wherein, described main body section is on a plane, and described elasticity arm is provided with the kink that protrudes from plane, described main part place.
Preferably, described main part comprises side and the fixed edge that links to each other with side, and described elasticity arm links to each other with described side and extends along described fixed edge.
Preferably, be relative extension and continuous mutually between the adjacent described elasticity arm.
Preferably, described fixed edge and described vibrating diaphragm are fixedly linked, described fixed edge is provided with also that some described vibrating diaphragm is provided with the support portion that is fixed on the described basin frame to the protuberance that protrudes away from the direction at main part center, and described protuberance abuts against on the described support portion.
Preferably, described voice coil loudspeaker voice coil and described vibrating diaphragm are fixedly linked.
Preferably, described fixed part comprises first fixed part that is extended by described elasticity arm bending and second fixed part that is extended by described first fixed part.
Preferably, described mini-sound device also is provided with shell, and described side is provided with some support arms to the described shell of support that protrudes away from the direction at main part center.
Preferably, described elasticity arm is provided with 4.
Preferably, described support arm is provided with 4.
[description of drawings]
Fig. 1 is the part stereochemical structure exploded view of the utility model mini-sound device.
Fig. 2 is the three-dimensional structure diagram of the spring leaf of the utility model mini-sound device.
[embodiment]
The utility model is described in further detail below in conjunction with drawings and embodiments.
Shown in Fig. 1-2, a kind of mini-sound device 1, it comprises basin frame 2, places the voice coil loudspeaker voice coil 21 in the basin frame 2, the vibrating diaphragm 4 that is fixed on the spring leaf 3 on the basin frame 2 and is fixedly linked with spring leaf 3.The fixed part 33 that spring leaf 3 is provided with main part 31, some elasticity arms 32 that links to each other with main part 31 and extend along main part 31 outsides and is extended by elasticity arm 32 bendings.Wherein, main part 31 is in the same plane, and elasticity arm 32 is provided with the kink 321 of the extended surface that protrudes from plane, main part 31 place.Because the protrusion direction of kink 321 is consistent with the direction of vibration of spring leaf 3, undulate.When spring leaf 3 vibrations, kink 321 can play cushioning effect to it, thereby has increased the elasticity of spring leaf 3, and spring leaf 3 can not fractureed because of amplitude is excessive easily yet.In the present embodiment, fixed part 33 comprises first fixed part 331 that is extended by elasticity arm 32 and second fixed part 332 that is extended by 331 bendings of first fixed part.This structure can make spring leaf 3 more firm being fixed on the basin frame 2.
Concrete, voice coil loudspeaker voice coil 21 is fixedly linked with vibrating diaphragm 4, and vibrating diaphragm 4 is fixedly connected on the main part of spring leaf 3.Main part 31 comprises side 311 and the fixed edge 312 that links to each other with side 311, and elasticity arm 32 links to each other with side 311 and extends along fixed edge 312.Fixed edge 312 is fixedly linked with vibrating diaphragm 4, and fixed edge 312 is provided with also that some vibrating diaphragm 4 is provided with the support portion 41 that is fixed on the basin frame 2 to the protuberance 5 that protrudes away from the direction at main part 31 centers, and protuberance 5 abuts against on the support portion 41.This structure can make between spring leaf 3 and the vibrating diaphragm 4 the better effect of fixedlying connected.
Mini-sound device 1 also is provided with shell 6, and side 311 is provided with some support arms 34 to the supporting housing 6 that protrudes away from the direction at main part 31 centers.
Concrete, in the present embodiment, elasticity arm 32 is provided with 4, is relative extension and continuous mutually between it.Support arm 34 is provided with 4, and is separated by a distance between it.Certainly, the quantity of elasticity arm 32 and support arm 34 is not limited only to this, also can be other quantity, but principle is the same.
Compare with correlation technique, the elasticity arm of the spring leaf of mini-sound device of the present utility model is because of being provided with and protruding from the kink on main part plane, vibration force when having cushioned the spring leaf vibration greatly, effectively prevent the phenomenon that spring leaf has fractureed when vibrating easily, and then improved the reliability of the utility model mini-sound device.
Above-described only is execution mode of the present utility model; should be pointed out that for the person of ordinary skill of the art at this, under the prerequisite that does not break away from the utility model creation design; can also make improvement, but these all belong to protection range of the present utility model.
