Referring to Fig.1~Fig. 4, small high-power loudspeaker 1 include:
Magnetic loop component 11；And
Frame 12 is connected on magnetic loop component 11,
Wherein, frame 12 is opened wide at the top of it forms opening, and the inside of frame 12 is equipped with funnelform cone 13, described spacious
The front side and rear side of mouth are separately installed with preceding elastic backing 132 and rear elastic backing 131.
Further, the left engaging lug of the front side integral formula of frame 12 being connected at left and right sides of magnetic loop component 11
121 and right engaging lug 122, rubber pad 15 is connected on left engaging lug 121 and right engaging lug 122.
Further, rubber pad 15 includes:
Columned main body 151；And
The dashpot 152 and clamping groove 153 being successively opened on 151 side of main body from front to back,
Wherein, it is in holding for the gesture being gradually reduced that the front end of main body 151, which is formed with along its cross section of direction from back to front,
Power end 154.In a preferred embodiment, pressure is equipped with annular flanging 14 at the neighboring of cone 13.
Referring to Fig. 2, the side of left engaging lug 121 and right engaging lug 122 begins with semi-closed card interface, left connection
Ear 121 is clamped with right engaging lug 122 by 153 phase of clamping groove of the respective card interface and rubber pad 15.
Further, the rear side of frame 12 is equipped at least one piece magnetic loop elastic backing for being located at 11 side of magnetic loop component
133。
