Embodiment Construction

[0030] In order to solve the deficiencies and defects of the prior art, the invention provides an inverted tube sound box, the inverted tube of which can be disassembled and replaced, and can be converted into a closed type sound box.

[0031] The following will be explained in conjunction with specific embodiments.

[0032] see figure 1 , which is a structural schematic diagram of the vented speaker of the present invention.

[0033] Such as figure 1 As shown, a phase-inverting sound box has a box body 10, and a speaker installation hole and a phase-inversion hole are provided on the box body 10. A speaker 20 is installed in the speaker installation hole, and a first phase-inversion tube is installed at the phase-inversion hole. 30, the first phase inversion tube 30 is detachably installed in the phase inversion hole, preferably a threaded engagement connection, that is, the phase inversion hole is provided with threads, and the threads provided on the outer wall of the fir...

Abstract

The invention relates to a phase inversion type sound box which is provided with a box body, a loudspeaker installation hole and a phase inversion hole are formed in the box body, a loudspeaker is mounted in the loudspeaker installation hole, a first phase inversion tube is mounted at the phase inversion hole, and the first phase inversion tube is detachably mounted in the phase inversion hole; the inverter further comprises a second inverter tube, the length and the tube diameter of the second inverter tube are both smaller than those of the first inverter tube, one end of the second invertertube is provided with an installation portion matched with the inverter hole, and the second inverter tube is detachably installed in the inverter hole through the installation portion. According tothe phase inversion type sound box, the phase inversion tube can be replaced; a user can select and use the inverter tubes with different tube diameters and lengths according to the actual condition of the sound box so as to obtain the required sound box effect.

Description

technical field [0001] The invention relates to a phase-inverted sound box, in particular to a sound box with a replaceable and detachable phase-inverted tube. Background technique [0002] A speaker is a device that converts an audio signal into sound. [0003] The closed speaker is the speaker system with the simplest structure, which consists of a speaker unit installed in a fully sealed box. The phase-inverted speaker is a type of speaker with a phase-inverted hole on the speaker panel. The difference between it and the closed-type speaker is that an inverter tube is installed on the panel of the speaker. The sound wave radiates to the front after passing through the inverter tube, superimposes with the sound wave in front of the speaker, and then radiates forward together to enhance the low frequency effect. [0004] The general principle of inverter tube design is the Helmholtz resonance principle formula: [0005] [0006] Among them, f 0 is the lowest resonanc...
