The application sets up the pressing mechanism and the blocking mechanism. When the hot air in the Bluetooth sound is discharged through the pressing mechanism, the pressing plate will extrude the air bag during the downward movement. At this time, the air pressure in the air bag will increase, and the gas in the air bag will be transported to the inside of the chamber through the pipe under the action of air pressure. The air pressure in the chamber will increase with the input of the gas, and the top plate will drive the connecting shaft and the blocking plate to move upward under the action of air pressure. At this time, the blocking plate will block in the air inlet hole. The wind power discharged by the heat dissipation fan will gather at the top of the cavity. When the pressing plate moves upward, the top plate will drive the blocking plate to move downward under the action of the spring. The blocking plate will move away from the air inlet hole, and the pressing plate will compress the space above the cavity when moving upward. The wind power gathered above the cavity will quickly enter the inside of the Bluetooth sound through the air inlet hole, so as to facilitate the rapid cooling of the inside of the Bluetooth sound. Through the cooperation between the pressing mechanism and the blocking mechanism, the hot air in the Bluetooth sound can be quickly and effectively discharged, and the inside of the Bluetooth sound can be effectively cooled by cold air. Otherwise, the Bluetooth sound is damaged due to poor heat dissipation effect. BRIEF DESCRIPTION OF DRAWINGS
