Embodiment

[0021] Embodiment: the phase-inverted barrel-shaped sound box of the present embodiment, such as figure 1 , figure 2 , image 3 with Figure 4 As shown, it includes a speaker body and a speaker bracket. The speaker body includes a barrel-shaped box body 1, a full-range speaker 2 installed on one side of the box body, and an inverter tube 3 installed in the box body 1. The body of the box body 1 The other end face is provided with an inverter hole 4, which coincides with the inverter tube 3, and one end of the inverter tube 3 is placed at the phase inverter hole 4 and is vertically fixedly connected to the rear end surface of the box body 1. The speaker adopts the principle of piggyback inverter, and the outlet of the inverter tube 3 is opened on the rear end surface of the cabinet. After the diameter d of the inverter tube 3 is determined, the length of the inverter tube 3 is L=2.25×10 3 × d 2 ÷ f B 2 V B -1.15d, at the same time, L1 , (where: L-inverted tube length (m...

Abstract

The invention discloses a wine bucket shaped loudspeaker box, comprising a loudspeaker box body and a loudspeaker box bracket; the loudspeaker box body comprises a wine bucket shaped box body and a loudspeaker arranged at the front end surface of the box body, a phase-reversing tube is arranged in the box body, a phase-reversing hole is arranged at the rear end surface of the box body, one end of the phase-reversing tube is arranged at the position of the phase-reversing hole and is vertically and fixedly connected with the rear end surface of the box body, the loudspeaker is electrically connected with an external sound source by a loudspeaker wiring terminal, wave mode sound absorption wool is arranged on the inner wall of the box body, the wine bucket shaped loudspeaker box eliminates the harmonic distortion and resonance of tone quality, caused by flat box body surfaces and edge corners of a common resonance, increases low-frequency diving power and reduces nonlinear distortion of audio frequency, the design of the wine bucket shaped box body changes the disadvantage that the common loudspeaker box has poor shock resistance, promotes the mechanical property of the loudspeaker box structure and can support high audio-frequency power; in addition, the wine bucket shaped appearance design of the loudspeaker box is artistic and elegant, and the function and the decoration are perfectly combined.

Description

technical field [0001] The invention relates to a sound box, in particular to a barrel-shaped sound box. Background technique [0002] At present, most of the existing speakers on the market are in the shape of a common long cube or a regular cube. Although such speakers are relatively simple and convenient to manufacture, their cabinet shapes are relatively common, and the cabinet has a greater impact on the playback quality of the sound quality. , the box with parallel walls is easy to produce harmful standing wave components, and the standing wave is easy to concentrate on a certain frequency, which will affect the vibration speed of the speaker cone. If it is too sharp, it will make the resonance problem of the panel more prominent. At the same time, sound waves (especially low frequency) will excite secondary waves on the corners of the long cube or cube-shaped box, causing the superposition of sound waves and affecting the phase. Accuracy, in addition, due to the abru...
