So that frame is connected with external power source convenience and is improved.
Further, the third pad includes two sub- pads of third, and described two sub- pads of third are separately positioned on
The left and right sides of the side.
As can be seen from the above description, can be electrically connected with external power supply by two sub- pads of third for being located at side, make
Frame is connected with external power source convenience and is improved.
Further, a kind of loudspeaker, further includes connection terminal, the connection terminal at least have there are two weldering
Disk, described two pads include the 4th pad and the 5th pad；
4th pad is connect with a first sub- pad, the 5th pad and a second sub- pad or one
The sub- pad connection of third；The connection of the voice coil of 4th pad and loudspeaker, the 5th pad and external power supply connect
It connects.
Preferably, electric connection terminal and frame are integrated injection mouldings, and when injection molding shows electric connection terminal localized metallic
It out, is exactly pad, i.e. the 4th pad is exactly the first pad, and the 5th pad is exactly the described second sub- pad or the sub- pad of third；
Increase pad face number, exactly by change electric connection terminal structure and expose metal covering come increased.
As can be seen from the above description, voice coil can be made to connect by connection terminal with external power supply by above structure.
Further, the rectangular box is all provided with fluted for being arranged at the position of pad, and groove is arranged in pad
Bottom；The depth of the groove is greater than the thickness of pad.
As can be seen from the above description, be arranged in groove by pad, after welding, no more than the monnolithic case of product, from
And increase the versatility of product.
Further, the upper surface of the rectangular box is equipped with the cavity through upper and lower surface.
Further, the first lateral wall of the washer is equipped with the first card slot；First card slot two sides it is opposite two
A side wall is arcwall face, and first card slot is gradually reduced along at the direction of the first lateral wall；
The cavity the first side wall opposite with first lateral wall is equipped with the first grab；The phase of first grab
Pair two lateral surfaces be arcwall face, and first grab along far from the first side wall direction at be gradually reduced, it is described first card
Hook is connect with first card slot；
First lateral wall is equipped with about symmetrical two the second grabs of first card slot；On the first side wall
Equipped with about symmetrical two the second card slots of first grab；Second grab is connect with second card slot.
Further, the washer second lateral wall opposite with first lateral wall is equipped with third card slot and two
Third grab, described two third grabs are symmetrical arranged about third card slot, the third card slot with first card slot
Shapes and sizes are all the same, and the shapes and sizes of the third grab and second grab are all the same；
The cavity second sidewall opposite with the first side wall is equipped with the 4th grab and two the 4th card slots, described
Two the 4th card slots are symmetrical arranged about the 4th grab, and the shapes and sizes of the 4th grab and the first grab are homogeneous
