[0040] Embodiment 3

[0041] Based on the second embodiment, Figures 1 to 5 As shown, the working principle of the device is mainly based on electromagnetic induction and acoustic principles. When an audio signal is input to the speaker, the audio signal first enters the speaker through the audio input interface. The audio signal is then converted into an electrical signal and drives the coil 3 in the speaker assembly to move in the stable magnetic field generated by the magnet assembly 2.

[0042] Specifically, when the electrical signal passes through the coil 3, it is acted upon by a force in the magnetic field, causing the coil 3 to vibrate. The vibration of the coil 3 is transmitted to the diaphragm 4 through the voice coil frame 5, and the diaphragm 4 vibrates accordingly. The vibration of the diaphragm 4 pushes the air in front of it, generating sound waves, which is the sound we hear. The cone 6 is installed in front of the diaphragm 4 to output the sound generated by the diaphragm 4 and transmit it to the outside through the speaker mesh 7. In this process, the frequency and amplitude of the electronic audio signal determine the speed and amplitude of the vibration of the voice coil 3 and the diaphragm 4, and thus determine the frequency and volume of the sound wave. Therefore, the speaker can accurately restore the sound information in the audio signal and provide clear and loud sound effects.

[0043] Embodiment 4

[0044] Based on the third embodiment, Figures 1 to 5 As shown, the installation steps of this device are:

[0046] 2) Punch holes and fix: Punch holes at the selected installation location, and use expansion screws 4 to fix the fixing bracket 5 and the support frame 10 to the wall and the ground respectively. Ensure a stable installation.

[0047] 3) Assemble the speaker: Connect and fix the hanging base 2 of the speaker housing 1 with the bracket hanging part 3 of the fixing bracket 5 by screws. At the same time, fix the supporting frame 10 to the bottom of the housing 1 by screws.

[0048] 4) Install the protective cover: Insert the rod 14 of the protective cover 13 into the socket 8 on the front of the housing 1 to achieve assembly with the housing 1. Ensure that the non-slip rubber rod sleeve at the end of the rod 14 fits tightly with the socket 8 to improve the stability of the connection.

[0049] Embodiment 5

[0050] Based on the fourth embodiment, Figures 1 to 5 As shown, the use and maintenance instructions of this device:

[0051] 1) Precautions for use: Make sure the power received by the speaker does not exceed its rated power to avoid burning the voice coil or damaging other components. Note that the impedance of the speaker should match the output line to obtain the best sound effect. Adjust the volume as needed to avoid discomfort caused by excessive or low volume.

[0052] 2) Maintenance method: Clean the surface of the speaker and the speaker mesh 7 regularly to keep it clean and beautiful.
