The first end matches the first mounting slot and is placed therein, the second end matches the second mounting slot and is placed therein, the first end is provided with a first through hole, the second end is provided with a second through hole, the thread rod of the first knob is passed through the first through hole and inserted the internal thread plug, the thread rod of the second knob is passed through the second through hole and inserted the other internal thread plug, thereby being fixedly mounted the handle. And the first end and the second end can rotate around the thread rod so that the handle can rotate.
The horn assembly includes a magnet, a T iron, a washer, a sound ring, a basin frame, a paper basin and a dust cover. The magnet is a ring shape, and the T iron is inserted into a ring hole of the magnet, and the sound ring is arranged between the magnet and the T iron. The washer is also a ring shape, arranged on the upper part of the sound ring. The basin frame is arranged on the washer, a centre of the basin frame is provided with a third through hole, the sound ring is inserted into the third though hole, the paper basin is arranged on the basin frame, a centre of the paper basin is provided with a four through hole, a dust cover is disposed in the paper basin to cover the fourth through hole. The shell has a third surface, the third surface lies between the first surface and the second surface. A periphery edge of the basin frame is fixed on the third surface. The third surface is provided with a third mounting slot matching with the basin frame. A third protective shell is disposed on the third surface, the third protective shell is fixed on the third surface to cover the basin frame, the paper basin and the dust cover and the third surface.
A high pitch unit is mounted on the third surface, at a position close to the first passive plate.
The shell is also provided with a fourth surface opposite to the third surface, a speaker terminal and a switch button for the outdoor speaker are disposed on the fourth surface.
The outdoor speaker is also provided with a circuit board, electrically connected to the horn assembly, the terminal, and the switch button. The outdoor speaker is also provided with a power interface that is electrically connected to the circuit board and power the circuit board through an external power supply.
The beneficial effects according to the technical scheme in present invention are as follows: the outdoor speaker described in the present invention has good bass effect, good sealing, rain and dust prevention, suitable for use outdoor.
In order to more clearly illustrate the technical schemes in the embodiments in the present invention, the drawings needed in the embodiments or the prior technical description are briefly introduced below. Obviously, the drawings described below are only some embodiments in the present invention, and for those skilled in the art, additional drawings may be obtained according to the drawings below without creative work.

It should be understood that the specific embodiments described herein are used only to interpret the present invention and are not used to define the present invention.
Referring to
The first passive plate 15 and the second passive plate 16 are respectively arranged with a plenty of sound holes 19. Low-frequency sound waves transmitted through the first passive plate 15 and the second passive plate 16 are further transmitted through the sound holes 19 and do not affect their sound effect.
The first protective shell 17, the first surface 11 and the first passive plate 15 are enclosed to form one chamber 20, the second protective shell 18, the second surface 12 and the second passive plate 16 are enclosed to form the other chamber 20. The chambers 20 are conducive to sound transmission.
A centre of the first protective shell 17 and that of the second protective shell 18 are recessed toward the shell 10 to form a first mounting slot 21 and a second mounting slot 22, a first knob 23 is mounted in the first mounting slot 21, a second knob 24 is mounted in the second mounting slot 22. The first knob 23 and the second knob 24 are installed in the first mounting slot 21 and the second mounting slot 22 in a common way in the art, and it may be by clamp and slot connection, threaded connection, screw connection, or the like. Specifically, referring to
Preferably, the outdoor speaker further comprises a handle 28 having a first end 281 and a second end 282, which are respectively mounted on the first surface 11 and the second surface 12, thereby facilitating to lift the outdoor speaker. Specifically, in the embodiment showing in
Preferably, a periphery 283 of the first end 281 and that of the second end 283 are protrude, the other parts 284 thereof are depressed to form a slot, both of the first knob 23 and the second knob 24 have a flat portion 241 and a bulge 242 raised upward from a center of the flat portion 241, the flat portion 241 is placed in the slot, the bulge 242 is convenient to rotate the knob 23, 24.
Referring to
A high pitch unit 33 is mounted on the third surface 30, at a position close to the first passive plate 15. The structure and the principle of the high pitch unit 33 are common general knowledge that should be known by those skilled in the art, and will not be repeated in the application.
The shell 10 is also provided with a fourth surface 34 opposite to the third surface 30, a speaker terminal 35 and a switch button 36 for the outdoor speaker are disposed on the fourth surface 34.
The outdoor speaker is also provided with a circuit board, electrically connected to the horn assembly 40, the terminal 35, and the switch button 36. The outdoor speaker is also provided with a power interface that is electrically connected to the circuit board and power the circuit board through an external power supply.
