Abstract

The utility model discloses a novel sound box with a foldback function, comprising a loudspeaker and a casing. The loudspeaker comprises a main amplification woofer, a main amplification tweeter, a foldback mid-bass speaker and a foldback tweeter. The casing is a polyhedral structure having one or more inclined side surfaces. One surface of the casing is provided with the main amplification woofer and the main amplification tweeter which are arranged symmetrically up and down or left and right. The inclined side surface of the casing or the surface opposite to the main amplification woofer and the main amplification tweeter is provided with the foldback mid-bass speaker and the foldback tweeter which are arranged symmetrically up and down or left and right. The sound box of the utility model has the foldback function, horizontal directivity of the sound box is enlarged, and sound amplified effect at the rear side of the sound box is enhanced. Demands for amplified sound on the stage and down the stage are satisfied simultaneously, production cost is saved and transportation is convenient.

Description

A kind of have a Novel sound box that returns auditory function
Technical field
The utility model relates to a kind of audio amplifier, relates in particular to a kind of Novel sound box that returns auditory function that has.
Background technology
Traditional audio amplifier is only provided with loud speaker in the front of casing, horizontal directivity is very limited, only meet the public address needs in audio amplifier front, proceeds posterolateral public address weak effect, when use need before the lights former and later two towards placing respectively audio amplifier, to meet the public address needs of the front spectators of stage with personnel on stage, so not only increase cost but also also caused inconvenience in carrying.
Utility model content
The purpose of this utility model is to provide a kind of horizontal directivity that can expand audio amplifier, strengthens the public address effect of proceeds posterolateral, has met on platform simultaneously and has followed the public address needs under platform, has saved the Novel sound box that returns auditory function that has of production cost and convenient transport.
To achieve these goals, the utility model adopts following technical scheme:
Have a Novel sound box that returns auditory function, comprise loud speaker and casing, described loud speaker comprises main public address woofer, main public address high pitch loudspeaker, returns and listen medium and low spectrum loudspeaker and return and listen high pitch loudspeaker; Described casing is the polyhedral structure with one or more prisms, described casing one side is provided with main public address woofer and main public address high pitch loudspeaker, described main public address woofer and main public address high pitch loudspeaker are up and down or left and right arranged distribution, the prism of described casing or be provided with to return with described main public address one side low, that high pitch loudspeaker is relative and listen medium and low spectrum loudspeaker and return and listen high pitch loudspeaker, described in return listen medium and low spectrum loudspeaker and described in return and listen high pitch loudspeaker to be up and down or left and right arranged distribution.
Further, described main public address woofer, main public address high pitch loudspeaker, return and listen medium and low spectrum loudspeaker and return and listen high pitch loudspeaker to be respectively one or more.
Compared with prior art, of the present utility model have a Novel sound box that returns auditory function, described casing is the polyhedral structure with one or more prisms, by main public address woofer and main public address high pitch loudspeaker being set in casing one side, described casing is at prism or low with described main public address, the one side setting that high pitch loudspeaker is relative is returned to listen medium and low spectrum loudspeaker and return and is listened high pitch loudspeaker, not only there is the auditory function of returning, expand the horizontal directivity of audio amplifier, strengthen proceeds posterolateral public address effect, met on stage with the public address needs under stage simultaneously, and save production cost and conveniently transported.
