Abstract
The utility model discloses a structure for improving bass radiation efficiency of a phase-reversing sound box, comprising a sound box body. The sound box body is internally provided with a loudspeaker and a phase-reversing tube, between which a semi-enclosed diaphragm is arranged so as to cut off direct closing state between the back of the loudspeaker and the phase-reversing tube. The structure improves bass radiation efficiency by cutting off a low-resistance channel between the loudspeaker and the phase-reversing tube.
Description
Technical field
The utility model relates to a kind of structure that improves reflex cabinet bass radiation efficiency.
Background technology
At present, reflex cabinet is because flexible design is various, be widely used in specialty and civilian sound equipment field, but, a lot of reflex cabinets are owing to the needs in the moulding cause the position of phase-reversing tube in casing unsatisfactory, certain one side as the too close loudspeaker of phase-reversing tube, because of gas also is liquid, it also follows pressure through the shortest (minimum drag) path transmission characteristic, thereby reduce the ability of loudspeaker cone (or being called vibrating diaphragm) radiation bass greatly, although the bass that loudspeaker send is behind strengthened by phase-reversing tube, but can not reach design level, this situation can produce the situation that the bass sound radiation pressure does not reach designing requirement, and electroacoustic engineering Shi Duocong improves dividing network or improves the bass horn characteristic and remedies, and causes too much increasing cost like this.
The utility model content
Problem to be solved in the utility model provide a kind of simple in structure, improve the structure of reflex cabinet bass radiation efficiency at low cost.
The technical scheme that the utility model adopted is: the structure that improves reflex cabinet bass radiation efficiency, comprise the audio amplifier body, be provided with loudspeaker and phase-reversing tube in the described audio amplifier body, be provided with half enclosed baffle between described loudspeaker and the phase-reversing tube to cut off the state that is directly adjacent between loudspeaker back and the phase-reversing tube.
The beneficial effects of the utility model are: the utility model has improved the bass radiation efficiency by cutting off the low resistance flow channel between loudspeaker and the phase-reversing tube.
Description of drawings
The utility model is described in further detail below in conjunction with the drawings and specific embodiments:
Fig. 1 is the inside perspective view of the utility model embodiment;
Fig. 2 is the sectional structure schematic diagram of the utility model embodiment.
Embodiment
Fig. 1 is the inside perspective view of the utility model embodiment, for clarity sake, removed the part Loudspeaker panel among Fig. 1, Fig. 2 is the sectional structure schematic diagram of the utility model embodiment, the structure that improves reflex cabinet bass radiation efficiency comprises audio amplifier body 1, be provided with loudspeaker 10 and phase-reversing tube 11 in the audio amplifier body 1, be provided with half enclosed baffle 12 between loudspeaker 10 and the phase-reversing tube 11 and cut off the state that is directly adjacent between loudspeaker 10 back and the phase-reversing tube 11, having avoided following pressure because of the gas that 11 casees inner mouths of pipe 111 of phase-reversing tube too cause near loudspeaker 10 transmits through the shortest (minimum drag) path, by cutting off this low resistance flow channel, improved the bass radiation efficiency.
Claims (1)
1, a kind of structure that improves reflex cabinet bass radiation efficiency, comprise the audio amplifier body, be provided with loudspeaker and phase-reversing tube in the described audio amplifier body, it is characterized in that: be provided with half enclosed baffle between described loudspeaker and the phase-reversing tube to cut off the state that is directly adjacent between loudspeaker back and the phase-reversing tube.
