Description

Can realize audio amplifier of sound kinetic energy reinforcing Technical Field The utility model relates to the technical field of sound, in particular to a sound box capable of realizing sound kinetic energy enhancement. Background Conventional enclosures typically increase sound loudness (e.g., inverter tube designs) by adding straight or bent-tube ventilation tubes. The sound wave propagation efficiency is enhanced by conducting the air inside and outside the box body. However, this prior art has significant drawbacks: The sound pressurizing force is insufficient, namely the straight pipe structure leads to unidirectional linear motion of air flow, the sound wave energy cannot be effectively overlapped, and the sound is submerged at low frequency to be weak; The sound purity is reduced, namely, the time difference exists between the airflow in the corner area and the airflow in the center to reach the ventilation pipe orifice, and phase interference is generated to cause turbidity of sound quality; The utilization rate of sound energy is low, and a large amount of airflow kinetic energy cannot be converted into effective sound pressure output due to disordered diffusion loss. To overcome the above-mentioned drawbacks, an innovative structure capable of directing airflow opposite to each other and improving the acoustic energy conversion efficiency is needed. Disclosure of utility model In order to overcome the defects of the prior art, one of the purposes of the utility model is to provide a sound box capable of realizing sound kinetic energy enhancement. One of the purposes of the utility model is realized by adopting the following technical scheme: A sound box capable of realizing sound kinetic energy enhancement comprises a box body and a box body front plate, wherein two tweeters and a middle woofer are symmetrically arranged on the box body front plate, an independent cavity partition board for a ventilation pipe is arranged in the box body, the inside of the box body is partitioned into independent cavities, a U-shaped ventilation pipe is arranged in each cavity, a plastic panel is fixed on the side face of the box body, and the plastic panel is integrated with an up/down curve and pause key, a high sound/bass/total sound volume control knob, a power switch, a sound source U disk input port, a DC power 5V input port and an Aux sound source input port. Further, the two tweeters are respectively positioned at the left side and the right side of the front plate of the box body, and the middle woofer is positioned at the center position between the two tweeters.
