Loudspeaker.
The utility model sound box is in cuboid body, and cabinet front is provided with a loudspeaker mounting hole, for installing
Loudspeaker unit；Box back surface is driveed there are two hole, and the size of two paraphase holes differs, and is respectively used to installation rotary table
Shape phase-reversing tube, described phase-reversing tube one end, which extends, is fixed on box house, and other end is fixed extraneous empty with cabinet by paraphase hole
Between be connected, make the air of inner space air and free surrounding space generate convection current.Maximum feature is exactly phase-reversing tube and outer
The hole area that boundary space communicates be it is stepping, be different from pervious straight trip phase-reversing tube, the same form of two phase-reversing tube sizes
Equally, installation direction is different unlike.When speaker operation, the air of inner space air and free surrounding space can be made to produce
Raw convection current, using the phase-reversing tube of truncated cone-shaped, area changes this improved structure with the change of length, passes through utilization
The pressure that diaphragm oscillations generate during speaker operation makes phase-reversing tube generate pressure difference, sends out the speaker external world and internal air
It is raw to continue convection current and achieve the effect that heat dissipation, in order to more effectively radiate, phase-reversing tube place up and down, phase-reversing tube below
It is responsible for air inlet, phase-reversing tube above is responsible for outlet, also meets the characteristic that hot gas itself has.High-pitched speaker and woofer point
It is not all connect with frequency divider, realizes high bass output.
The utility model has the following advantages that compared with prior art：Not only radiating rate is fast, high-efficient, and structure is simple
It is easily achieved, improves the rated power of loudspeaker, and bass dynamics sense is strong, strong and weak clearly demarcated, the limpid exquisiteness of high pitch, stereovision
Good, distortion is small, not messy.
