The utility model provides a kind of headphone loudspeaker, and as shown in Figure 1, these headphone loudspeaker comprise vibrating diaphragm, plastics frame 2, voice coil loudspeaker voice coil 3 and magnetic circuit system.Vibrating diaphragm is arranged in described plastics frame 2, and voice coil loudspeaker voice coil 3 is arranged in described plastics frame 2, and described voice coil loudspeaker voice coil 3 can be connected with described vibrating diaphragm.Described voice coil loudspeaker voice coil 3 is provided with voice coil leads 31, for external signal is introduced voice coil loudspeaker voice coil 3.One end of described voice coil leads 31 is connected on described voice coil loudspeaker voice coil 3, and the other end is drawn from described plastics frame 2.In the utility model, described plastics frame 2 is provided with opening 21, described voice coil leads 31 can cause outside plastics frame 2 from described opening 21.Described vibrating diaphragm comprises ring 11 and pressure ring 12, described ring 11 is made up of film material, it is the agent structure of vibrating diaphragm, described pressure ring 12 is arranged on the edge of described ring 11, for playing a supporting role to ring 11, when vibrating diaphragm is arranged in described plastics frame 2, described pressure ring 12 also plays fixing effect.Described voice coil loudspeaker voice coil 3 can be connected on the downside surface of described ring 11, and described voice coil leads 31 is bonded in the lower surface of described ring 11, and the voice coil leads 31 extending to described opening 21 place is crushed between described pressure ring 12 and plastics frame 2 usually.Especially, as shown in Figure 2, the outward flange of described pressure ring 12 has straight line relief portion 121, and in the position of described straight line relief portion 121, the outward flange of described pressure ring 12 is not arc, but extends straight.When described vibrating diaphragm is arranged in described plastics frame 2, described straight line relief portion 121 should be corresponding with described opening 21 position, that is, described straight line relief portion 121 is positioned at directly over described opening 21, described opening 21 aligns with described straight line relief portion 121, as shown in Figure 4.The position that the edge of described ring 11 coordinates with the straight line relief portion 121 of described pressure ring can have straight line and dodge part, better dodges effect to be formed.Certainly, ring 11 is not arranged straight line dodge part also realize technique effect of the present utility model.Like this, described voice coil leads 31 can not be subject to two Slideslips of effect to opening 21 of arc pressure ring 12 at described opening 21 place, and then avoids voice coil leads 31 and slide along pressure ring 12 and be cut off, or the both sides sliding to described opening 21 are disconnected by card.Fig. 3 is just to the partial enlarged drawing of described opening 21, visible, in embodiment of the present utility model, described voice coil leads 31 usually not with two side contacts of described opening 21.If the headphone loudspeaker that the utility model provides are impacted; because pressure ring 12 has straight line relief portion 121; so the edge of pressure ring 12 also can not make voice coil leads 31 have trend to opening 21 liang of Slideslips; protect voice coil leads 31 to a certain extent to be broken by the edge card of opening 21, or by the edge exclusion of described pressure ring 12.
The utility model does not limit the generation type of described straight line relief portion and structure, those skilled in the art can according to actual conditions, straight line relief portion is formed in different ways, as long as the outer surface of described pressure ring has one section of straight line portion both can reach basic effect at the edge of described pressure ring.Such as shown in Fig. 2, in a kind of embodiment of the present utility model, can direct truncated part circular arc on the outward flange of described pressure ring 12, thus form straight line portion, namely define described straight line relief portion 121.The moulding process of this straight line relief portion 121 is simple, Stability Analysis of Structures.But after described vibrating diaphragm is arranged in described plastics frame 2, likely there is situation about rotating in described vibrating diaphragm, described straight line relief portion 121 departs from described opening 21.In another kind of embodiment, as shown in Figure 4, can offer a rectangular recess on the outward flange of described pressure ring 12, like this, namely the base of described rectangular recess defines straight line portion, as described straight line relief portion 121.Two sides of described rectangular recess may be used for fixing described pressure ring 12, prevent pressure ring 12 from rotating.Such as, above two sidewalls of described opening 21, can be respectively arranged with backstop platform, when described pressure ring 12 is arranged in described plastics frame 2, the backstop platform above described opening 21 just in time can be stuck in the inner side of the side of described rectangular recess.Like this, can prevent described pressure ring 12 from rotating relative to described plastics frame 2, described straight line relief portion 121 is remained on above described opening 21.The moulding process relative complex of this straight line relief portion 121, and complicated structure, but the effect of location can be played.Those skilled in the art can also adopt the straight line relief portion of other version, and the utility model does not limit this.
Preferably; in order to protect described voice coil leads 31 further; the width of the opening 21 in described plastics frame 2 can not be too small; the width of usual described opening 21 is 1-3mm; if the width of described opening 21 is narrow; then voice coil leads 31 inconvenience is passed from described opening 21, and voice coil leads 31 is also easily stuck in the both sides of described opening 21, easily occurs cutting off, blocking disconnected situation.And if the width of described opening 21 is wide, the structural stability of described plastics frame 2 can reduce.More preferably, the width of described opening 21 can between 2-3mm, and within the scope of this, opening 21 can either provide enough spaces to pass for voice coil leads 31, also can not have an impact to the structural stability of plastics frame 2.In a kind of embodiment of the present utility model, as shown in Figure 3, the width of described opening 21 is 2.5mm.
Preferably, be fixedly installed in described plastics frame 2 to make described vibrating diaphragm, can be provided with erecting bed 22 inside described plastics frame 2, described pressure ring 12 can be set directly on described erecting bed 22, and the outward flange of described pressure ring 12 is then stuck on the sidewall of described erecting bed 22.In this case, described voice coil leads 31 is crushed between described erecting bed 22 and described pressure ring 12 usually.
In addition, as shown in Figure 1, described vibrating diaphragm can also comprise ball top layer, and described ball top layer is arranged on described ring 11, and described ball top 13 is for improving the vibration performance of described vibrating diaphragm.Described magnetic circuit system is for driving the parts of described voice coil loudspeaker voice coil 3 in described headphone loudspeaker.Described magnetic circuit system can comprise magnet 41, washer 42 and U-shaped iron 43, and described washer 42 is arranged on described magnet 41, and described magnet 41 is arranged in described U-shaped iron 43, has magnetic gap between the side of described magnet 41 and the sidewall of described U-shaped iron 43.
As shown in Figure 1, described headphone loudspeaker can also comprise pcb board 5, and described pcb board 5 can be arranged on the outside of described plastics frame 2, such as, be arranged on bottom described plastics frame 2.One end that described voice coil leads 31 is drawn from plastics frame 2 should be electrically connected with described pcb board 5, and described pcb board 5 is electrically connected with external circuit further, thus is passed to by voice signal in described headphone loudspeaker.
Although be described in detail specific embodiments more of the present utility model by example, it should be appreciated by those skilled in the art, above example is only to be described, instead of in order to limit scope of the present utility model.It should be appreciated by those skilled in the art, when not departing from scope and spirit of the present utility model, above embodiment can be modified.Scope of the present utility model is limited by claims.
