Along with the expansion in consumer electronics market, the consumer electronics products such as a large amount of mobile phones, notebook computer are used widely, and as acoustic element important in consumer electronics product, loud speaker has demand widely.
Loud speaker, comprising: auxiliary system, comprises protecgulum and shell; Magnetic circuit system, comprises the washer and the magnet that combine from top to bottom, and magnetic circuit system is provided with magnetic gap; Vibrational system, the voice coil loudspeaker voice coil that comprises vibrating diaphragm and combine with vibrating diaphragm, voice coil loudspeaker voice coil is arranged in magnetic gap; The curent change being arranged in the voice coil loudspeaker voice coil in magnetic gap makes the magnetic field force induced effect of voice coil loudspeaker voice coil produce vibration, drives vibrating diaphragm vibration sounding.But in prior art, back-off magnetic structure can not carry out unsettled lead-in wire, causes complex manufacturing.
Therefore, be necessary to propose a kind of improvement, to overcome prior art loud speaker defect.
Utility model content
The technical assignment of the technical problems to be solved in the utility model and proposition is that prior art scheme is improved and improved, and provides a kind of production technology simple loud speaker.
To achieve these goals, the utility model by the following technical solutions: the technical scheme that the invention for solving the technical problem adopts is: loud speaker, comprising: auxiliary system, comprises protecgulum and shell; Magnetic circuit system, comprises the washer, magnet and the magnetic conductive board that combine from top to bottom, and magnetic circuit system is provided with magnetic gap; Vibrational system, the voice coil loudspeaker voice coil and the composite bed that comprise vibrating diaphragm and combine with vibrating diaphragm, voice coil loudspeaker voice coil is arranged in magnetic gap; And: described shell inner side is provided with the stretching wall and the groove that arrange for going between.
As the preferred technical scheme of one, magnetic circuit system is double magnetic circuit system, comprise centring magnet, centring magnet is fixedly installed the center washer corresponding with centring magnet shape near protecgulum one side, be provided with limit magnet around centring magnet, limit magnet is fixedly installed the limit washer corresponding with limit magnet shape near protecgulum one side, and centring magnet and limit magnet form magnetic gap.
As the preferred technical scheme of one, described shell is provided with the stretching wall arranging for going between near described limit washer one side, on described stretching wall, be provided with groove, and described limit washer is provided with near described shell one side the flanging coordinating with described stretching wall.
The beneficial effects of the utility model: owing to taking such scheme, the lead-in wire of the utility model loud speaker can carry out fair line arrangement in groove, and technique is simple, cost is low and be convenient to automated production.
Brief description of the drawings
Fig. 1 is the embodiment explosive view of the utility model loud speaker.
Fig. 2 is the cross-sectional view of loud speaker shown in Fig. 1.
Fig. 3 is the structure for amplifying schematic diagram of the part of A shown in Fig. 2.
Embodiment
In order to make the purpose of this utility model, technical scheme and advantage clearer, below in conjunction with drawings and Examples, the utility model is further elaborated.Should be appreciated that specific embodiment described herein is only in order to explain the utility model, and be not used in restriction the utility model.
The utility model loud speaker, as shown in Figure 1, comprises the auxiliary system being made up of protecgulum 11 and shell 12, and protecgulum 11 and shell 12 surround cavity, accommodate and be fixed with vibrational system and magnetic circuit system in cavity.Vibrational system comprises vibrating diaphragm 22, the voice coil loudspeaker voice coil 23 and the composite bed 21 that combine with vibrating diaphragm; Magnetic circuit system comprises centring magnet 32, centring magnet 32 is fixedly installed the center washer 31 corresponding with centring magnet 32 shapes near protecgulum 11 1 sides, be provided with limit magnet 42 around centring magnet 32, limit magnet 42 is fixedly installed the limit washer 41 corresponding with limit magnet 42 shapes near protecgulum 11 1 sides, centring magnet 32 and limit magnet 42 are fixedly installed magnetic conductive board 5 away from protecgulum one side, centring magnet 32 forms magnetic gap with limit magnet 42, and voice coil loudspeaker voice coil 23 is arranged in magnetic gap.The lead-in wire of voice coil loudspeaker voice coil 23 and the electric combination of electrical connector 6, the signal of telecommunication of external circuit reaches in voice coil loudspeaker voice coil 23 by electrical connector 6, and the interior curent change of voice coil loudspeaker voice coil 23 makes the magnetic field force induced and up-down vibration of voice coil loudspeaker voice coil 23, and voice coil loudspeaker voice coil 23 vibrations drive vibrating diaphragm 22 vibration soundings.
As shown in Figure 2 and Figure 3, the utility model loud speaker, shell 12 is provided with stretching wall near described limit washer 41 1 sides, is provided with the groove 121 arranging for going between on stretching wall, and limit washer 41 is provided with near shell 12 1 sides the flanging coordinating with described stretching wall.Lead-in wire can carry out fair line arrangement in the groove of shell stretching wall 121, and technique is simple, and cost is low and be convenient to automated production.
The foregoing is only preferred embodiment of the present utility model; not in order to limit the utility model; all any amendments of doing within spirit of the present utility model and principle, be equal to and replace and improvement etc., within all should being included in protection range of the present utility model.
