Utility model content
The utility model needs bass and alt in handle to install respectively for solving to show in array speaker, waveform reduction distortion is easily caused to produce serious distortion, volume is larger, produce, use inconvenience, cost is higher, and can mutually interference between existing coaxial array bugle audio amplifier voice coil loudspeaker voice coil, cause the deficiencies such as the motion that two voice coil loudspeaker voice coils can not be correct, a kind of linear array active audio amplifier is provided.
A kind of linear array active audio amplifier, comprise sound box, loud speaker and the active module embedded therein with DSP be made up of plank, two D class passage power amplifiers are provided with in described DSP, described casing comprises front chamber and rear chamber, dividing plate is provided with between described front chamber and rear chamber, described separator face is provided with voice unit to a middle side part of front chamber, the middle part of described front chamber is provided with bugle, described bugle is connected with active module embedded therein by D class passage power amplifier, the both sides of described bugle are provided with loud speaker, and described loud speaker is longitudinal linear array distribution.
Further, the biside plate of described front chamber and described dividing plate joint are fixed with aluminium suspender member by latch.
Further, be provided with swash plate between the side plate of described front chamber and base plate, described loud speaker is fixed on swash plate.
Further, the middle part of described front chamber biside plate is provided with hand and takes out, and hand takes out the space being positioned at described swash plate, side plate, base plate formation.
Further, described front chamber header board be set to iron net.
Further, the number of loudspeakers in described casing is at least 2.
Further, the end view of described casing is trapezoidal.
Further, described active module embedded therein is fixed on the rear plate of rear chamber.
By above description, the utility model advantage is: by arranging two D class passage power amplifiers in casing, when high pitch play by needs, by bugle by the wherein expanding channels in voice unit and two D class passage power amplifiers.When bass play by needs, by another expanding channels in bugle and two D class passage power amplifiers.Same loud speaker so just can be utilized to realize regulating high bass separately, solve in coaxial bugle audio amplifier and can mutually disturb between two voice coil loudspeaker voice coils, cause the problem of the motion that two voice coil loudspeaker voice coils can not be correct, then by the diffusion loading effect of bugle, effectively ensure that the radiation characteristic of long drive sound field.
