With the progress of society, people yearn for a more colorful life. As a form of entertainment that has been passed down for thousands of years, singing and dancing have penetrated into the lives of people of all ethnic groups. However, with the development and progress of science and technology, people have more and more requirements for the performance forms and venues of singing and dancing. The audio system is constantly improving and perfecting with people's needs. It can be as large as meeting the needs of live sound reinforcement for concerts of tens of thousands of people, or as small as meeting the needs of playing musical instruments and singing karaoke in personal families. An important device in the audio system is the speaker, which is generally composed of a speaker unit and a cabinet. The speaker unit is the sound-producing component, and the cabinet plays a role in correcting the sound as a supplement to the speaker unit. The sound-generating principle of the speaker unit is a conversion of electrical energy into sound. When different electronic energies are transmitted to the coil, the coil generates an energy that interacts with the magnetic field of the magnet. This interaction causes the paper plate to vibrate. Because the electronic energy changes at any time, the coil of the speaker will move forward or backward, so the paper plate of the speaker will move with it. These actions cause the density of the air to change and produce sound.

[0035] There are four anti-skid pads 3 made of rubber. The anti-skid pads 3 are fixed at the four corners of the bottom of the box 1 to increase the friction between the box 1 and the ground, thereby improving the stability of the box 1. When external force presses on the top of the box 1, the anti-skid pads 3 provide a buffer for the box 1 to prevent the box 1 from being damaged by pressure.

[0036] When the speaker is working, the midrange part 201 and the bass part 202 begin to vibrate and produce sound, and the air inside the speaker will also vibrate and produce noise. The middle partition 103 separates the midrange part 201 and the bass part 202 to prevent the midrange part 201 and the bass part 202 from interfering with each other and affecting the sound quality of the speaker. The two midrange sleeves 102 respectively cover the bottom ends of the two midrange parts 201, strengthen the isolation of the midrange part 201 from the air vibration, and prevent the noise inside the speaker from being diffused by the midrange part 201, thereby improving the signal-to-noise ratio and the listening experience; the sealing cover 107 covers the opening of the decorative part 204 inside the speaker to prevent the air inside the speaker from overflowing or out of the opening of the decorative part 204 The air flows in from the opening of the decorative part 204, disturbing the air inside the speaker and generating noise. The left and right two-way U-shaped air outlets 105 guide the air at the bottom of the speaker into the air outlet 203 through the paper tube 106 to prevent resonance and improve the sound quality of the speaker. The gravity part 108 lowers the center of gravity of the box 1, and it is not easy to tip over and cause damage to the box 1 when an external force collides. The speaker is light as a whole, and only the gravity part 108 is added to the bottom, which increases its stability and facilitates carrying. The anti-skid pad 3 increases the friction between the box 1 and the ground, thereby improving the stability of the box 1. When an external force presses on the top of the box 1, the anti-skid pad 3 provides a buffer for the box 1 to prevent the box 1 from being damaged by pressure.
