[0029] like Figure 1-7 As shown, a lightweight loudspeaker lighting device includes a control component 100 and a lighting and loudspeaker component 200.

[0030] like Figure 2 and Figure 3 As shown, the control assembly 100 includes: quick-release piece 101, connector 102, upper cover 103, control board 104, middle shell 105, servo motor 106, swing arm 107, drive shaft 108, flange shaft 109, and lower cover 110.

[0031] The quick-release component 101 connects to the aircraft mount, and the connector 102 connects to the aircraft to achieve power supply and network connection.

[0032] The control assembly 100 control box includes an upper cover 103, a middle shell 105, and a lower cover 110. The upper and lower end faces of the middle shell 105 are fixed with screws to form a closed cavity for mounting the control board 104 and the servo motor 106. The control board 104 is installed in the inner cavity of the upper cover and is electrically connected to the connector 102 on the quick-release piece 101 through a connecting wire.

[0033] Servo motor 106 is a dual-axis design, with one side being the output shaft that can output torque and the other side being the driven shaft that cannot rotate. The swing arms 107 are installed on both sides of servo motor 106 and connected in the middle by drive shaft 108. The rotation of the output shaft of servo motor 106 is converted into dual-axis rotation of the flange shafts 109 on the left and right sides. The flange shafts 109 are fixed to the lighting and megaphone assembly 200 by set screws.

[0034] like Figure 2 and Figure 5 as well as Figure 7 As shown, the illuminated megaphone assembly 200 includes: a back cover 201, a magnet 202, a coil fixing block 203, a diaphragm 204, an inner reflector block 205, a coil fixing bracket 206, a wire guide block 207, a connecting post 208, a cover plate 209, a horn fixing bracket 210, a horn 211, a small cover plate 212, a connecting block 213, and an illumination lamp 214.

[0035] The lighting and announcement assembly 200 includes two units: announcement and lighting. The announcement unit includes a horn 211, which is fixed to a horn fixing bracket 210. The rear end of the horn fixing bracket 210 is fixedly connected to a cover plate 209 to form a sealed cavity for internal circuit wiring of the announcement and lighting.

[0036] The cover plate 209 is connected to the coil fixing bracket 206 via the wire guide block 207 and four connecting posts 208. The front middle of the coil fixing bracket 206 is bonded to the horn 211 to amplify and propagate the sound. The rear end of the coil fixing bracket 206 is a recessed groove for installing the inner reflector block 205. The rear end of the inner reflector block 205 is fitted with the diaphragm 204. The connecting wire of the diaphragm 204 is transferred through the coil fixing bracket 206 and leads to the inner cavity of the horn fixing bracket 210.

[0037] The coil fixing bracket 206 is a PCB circuit board. The diaphragm 204 is wound and embedded in the magnet 202. Magnetic fluid is poured between the diaphragm 204 and the magnet 202 to conduct the heat of the coil to the magnet 202. The magnet 202 is an N52H high magnetic magnet, which can produce a higher volume. The rear end of the magnet 202 is a back cover 201. The outer side of the back cover 201 is arranged with heat dissipation teeth with a nano carbon heat dissipation coating. The inner cavity is in close contact with the magnet 202, which can effectively conduct and dissipate the heat of the magnet 202 into the air.

[0038] The left side of the horn fixing bracket 210 is fixed with a wire guide shaft by a set screw. The wire guide shaft is connected to the swing arm 107 of the servo motor 106 to realize the rotation of the lighting and announcement component 200. The connecting wire inside the horn fixing bracket 210 passes through the axis of the wire guide shaft and is connected to the control board 104.

[0039] The right side of the horn fixing bracket 210 is fixedly connected to the connecting block 213. The right side of the connecting block 213 is fixedly installed with the lighting lamp 214. The connecting wire of the lighting lamp 214 enters the horn fixing bracket 210 through the connecting block 213. The small cover plate 212 covers the connecting block 213 and applies waterproof glue.

[0040] The main shaft of servo motor 106 is a controllable steering shaft, capable of active rotation and torque output. The output end of the main shaft is fixedly connected to the swing arm 107. The secondary shaft of servo motor 106 cannot rotate actively or output torque. The secondary shaft of servo motor 106 is fixedly connected to another swing arm 107. The swing arm 107 on the main shaft side of servo motor 106 is fixedly connected to another swing arm 107 on the secondary shaft side of servo motor 106 via a drive shaft 108. When the main shaft of servo motor 106 rotates, it drives the secondary shaft to rotate via the swing arm 107 and drive shaft 108, simultaneously transmitting torque to the secondary shaft and outputting it to the flange shaft 109 on the secondary shaft side of servo motor 106. The lighting and megaphone assembly 200 consists of two modules, left and right, fixed on the flange shafts 109 on the left and right sides. These modules rotate with the flange shafts 109, performing a flipping motion to achieve a 90-degree change in the direction of the lighting and megaphone.

[0041] The horn 211 in the lighting and megaphone assembly 200 has a special exponential shape, which enables it to achieve a longer transmission distance. At the same time, the magnet 202 is a strong magnet, which enhances the frequency and amplitude characteristics of the diaphragm 204 and greatly increases the volume of the loudspeaker.

[0042] Although embodiments of the present invention have been shown and described above, it is understood that the above embodiments are exemplary and should not be construed as limiting the present invention. Those skilled in the art can make changes, modifications, substitutions and variations to the above embodiments within the scope of the present invention.
