Abstract
The invention discloses a convection type phase-inverted type sound box. The sound box comprises a box body, a loudspeaker and a power amplifier IC, wherein the loudspeaker and the power amplifier IC are arranged on the box body. A loudspeaker hole is arranged on the front of the box body and is used for the installation of the loudspeaker. Two circular phase-inverted holes are arranged on the back and are respectively a large circular phase-inverted hole and a small circular phase-inverted hole. An upper phase-inverted tube and a lower phase-inverted tube are respectively arranged in the large circular phase-inverted hole and the small circular phase-inverted hole. The large circular lower phase-inverted tube of the box body forms an air inlet, and the small circular upper phase-inverted tube forms an air outlet. When the loudspeaker works, pressure generated by the vibration of a vibrating diaphragm drives the phase-inverted tubes to generate pressure difference, thus continuous convection is generated between the outer sound box and the inner air and the effect of heat dissipation is realized. According to the design of the invention, the large diameter phase-inverted tube below the sound box carries out air inlet, and the above small diameter phase-inverted tube carries out air outlet; the characteristics of heat are met; the sound box has the advantages of fast heat dissipation speed, high efficiency and simple structure; and the efficiency and the service lives of the loudspeaker, the power amplifier IC and other electronic components in the sound box are improved.
