Abstract
The utility model discloses an intermediate-frequency phase structure comprising a phase plate and a phase plug. The phase plate is equipped with a horn opening and phonating holes. The phase plug is disposed on the inner surface of the phase plate and is an outwardly-protruding circular plug matched with the horn opening. The phase plug is equipped with a diamond phonating groove which is changed from a circle to a long-strip shape. Compared with a product in the prior art, the intermediate-frequency phase structure collects and compresses sound waves radiated to various directions by an alto horn and radiates the sound waves through the phonating holes so as to achieve purposes of correcting propagation direction and increasing sensitivity. The intermediate-frequency phase structure is used for a V-shaped installation multi- intermediate-frequency loudspeaker box and is capable of reducing the phase interference between horns and increasing intermediate-frequency sensitivity.
Description
Technical field
The utility model relates to the audio amplifier field, exactly refers to a kind of intermediate frequency phase structure.
Background technology
The tradition V-shape is installed many middle sound box with sound, and because horn mouth is diffused, the sound wave of loudspeaker is to all directions radiation, and the phase place between each loudspeaker is interfered mutually.
The utility model content
At above-mentioned defective, the technical problem that the utility model solves is to provide a kind of intermediate frequency phase structure, mediant trumpet can be collected compression to the sound wave of all directions radiation, radiate by phonate hole, to reach the purpose of correcting the direction of propagation and improving sensitivity, it is used for the audio amplifier that V-shape is installed many middle pitches, can reduce the phase interference between the loudspeaker, and can improve intermediate frequency sensitivity.
In order to solve above technical problem, the intermediate frequency phase structure that the utility model provides, comprise phase-plate and phase plug, described phase-plate is provided with horn mouth and phonate hole, described phase-plate inner surface arranges described phase plug, described phase plug for and the circle plug to outer lug that is complementary of described horn mouth, water caltrop shape is set on the described phase plug becomes strip by circle and go out sound track.
Preferably, described phonate hole is that symmetric points are symmetrical arranged with described phase plug center.
Preferably, described phonate hole is the ellipse hole that penetrates described phase-plate.
Preferably, described bell-mouthed diameter range is 60mm-100mm.
Preferably, the minor axis of described phonate hole is 35mm-55mm, and major axis is 130mm-180mm.
The intermediate frequency phase structure that the utility model provides, comprise phase-plate and phase plug, described phase-plate is provided with horn mouth and phonate hole, described phase-plate inner surface arranges described phase plug, described phase plug for and the circle plug to outer lug that is complementary of described horn mouth, water caltrop shape is set on the described phase plug becomes strip by circle and go out sound track.Compared with prior art, the intermediate frequency phase structure that the utility model provides, mediant trumpet can be collected compression to the sound wave of all directions radiation, radiate by phonate hole, to reach the purpose of correcting the direction of propagation and improving sensitivity, it is used for the audio amplifier that V-shape is installed many middle pitches, can reduce the phase interference between the loudspeaker, and can improve intermediate frequency sensitivity.
