Detailed Description

Referring to fig. 1-3, the present invention provides an embodiment: the utility model provides a waterproof type broad voice speaker, including threaded

cylinder

2, 2 front end fixedly connected with loudspeaker 1 of threaded cylinder, 1 intermediate position fixed connection sound transmission water proof membrane 11 of loudspeaker, 2 inner wall front end threaded connection of threaded cylinder has threaded

ring

14, 14 inner wall fixedly connected with vibrating diaphragm book ring 17 of threaded ring, 17 inner wall fixedly connected with cone-shaped paper dish of vibrating diaphragm book ring, 4 rear ends of cone-shaped paper dish are provided with voice coil

loudspeaker voice coil

5, 5 outer walls of voice coil loudspeaker voice coil are provided with stationary

core support piece

6, 5 rear ends of voice coil loudspeaker voice coil are provided with frame 7, frame 7 rear end is provided with magnet 8, 8 rear ends of magnet are provided with threaded

disc

9, 9 rear ends of threaded disc are provided with bolt 10, cone-shaped paper dish front end intermediate position is provided with nut 3, 4 rear end top intermediate position run through and fixedly connected with waterproof plug 16, pass through first through-hole 12 with bolt 10, second through-hole 13, third through-hole 15, voice coil loudspeaker voice coil 5 and cone-shaped paper dish 4 then are connected with nut 3, cone-shaped paper basin 4 passes through the socket 16 and puts up the socket and makes cone-shaped paper dish 5 and cone-shaped paper cone-shaped loudspeaker voice coil loudspeaker voice through, thereby the vertical movement is guaranteed to pass through cone 4 and the vertical sound transmission water proof cone is produced through cone 5, thereby the cone of cone vibration cone is used for the vertical sound transmission water proof sound cone 5.

The loudspeaker is characterized in that a nut 3 is in threaded connection with a bolt 10, a second through hole 13 penetrates through and is arranged in the middle of the front end of a threaded disc 9, a first through hole 12 penetrates through and is arranged in the middle of the front end of a magnet 8, a third through hole 15 penetrates through and is arranged in the middle of the rear end of a frame 7, the threaded disc 9 is in threaded connection with a threaded cylinder 2, the magnet 8 is electrically connected with a waterproof plug 16, water is prevented from flowing into the threaded cylinder 2 along a loudspeaker 1 in the sound production process of a cone-shaped paper cone 4 through a sound-transmitting waterproof membrane 11, the threaded disc 9 and a threaded ring 14 are screwed into the threaded cylinder 2, the magnet 8, a fixed core support piece 6, a voice coil 5, the cone-shaped paper cone 4 and a vibrating diaphragm folding ring 17 are effectively fixed in the threaded cylinder 2, then water can be prevented from flowing into the rear end of the threaded cylinder 2 through the threaded disc 9, the waterproof plug 16 is adopted, all-directional protection is carried out on the loudspeaker, the waterproof plug is greatly improved, and the waterproof performance is achieved, and the waterproof performance of the loudspeaker is effectively avoided that the loudspeaker is damaged due to contact with water, so that the service life of the loudspeaker is affected.
