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.

Embodiment

Below in conjunction with the drawings and specific embodiments, the utility model is described in further detail.

Please refer to Fig. 1, Fig. 2, Fig. 3 and Fig. 4, a kind of have a Novel sound box that returns auditory function, comprises loud speaker and casing 1, and described loud speaker comprises main public address woofer 2, main public address high pitch loudspeaker 3, returns and listen medium and low spectrum loudspeaker 4 and return and listen high pitch loudspeaker 5; Described casing 1 is for having the polyhedral structure of one or more prisms, the present embodiment is preferably two prisms, listen medium and low spectrum loudspeaker 4 and return and listen high pitch loudspeaker 5 by arranging at casing 1 prism and the back side to return, overcome spectators that traditional audio amplifier horizontal directivity can only be below stage and cannot be on platform personnel's shortcoming, expand the horizontal directivity of audio amplifier, make the horizontal directivity of the utility model audio amplifier can be on stage personnel, strengthen the public address effect at sound box side rear.

Described casing 1 front is provided with main public address woofer 2 and main public address high pitch loudspeaker 3, described main public address woofer 2 and main public address high pitch loudspeaker 3 are up and down or left and right arranged distribution, described main public address woofer 2, main public address high pitch loudspeaker 3 are one or more, the present embodiment is preferably two woofers 2 and a main public address high pitch loudspeaker 3, for meeting the front spectators' of stage public address demand, described casing 1 is at left prism, right prism or with described main public address woofer 2, the dorsal surface that high pitch loudspeaker 3 is relative is provided with to return to be listened medium and low spectrum loudspeaker 4 and returns and listen high pitch loudspeaker 5, described return listen medium and low spectrum loudspeaker 4 and described in return and listen high pitch loudspeaker 5 to be up and down or left and right arranged distribution, described returning listened medium and low spectrum loudspeaker 4 and returns and listen high pitch loudspeaker 5 for one or more, the present embodiment returns described in being preferably one to be listened medium and low spectrum loudspeaker 4 and one to return to listen high pitch loudspeaker 5, due to described return listen medium and low spectrum loudspeaker 4 and described in return listen the left and right prism at high pitch loudspeaker 5 places or the back side be all dorsad spectators towards stage direction, expand the horizontal directivity of audio amplifier, strengthen sound box side rear amplifying effect, therefore can meet the public address demand of personnel on stage.

Of the present utility model have the Novel sound box that returns auditory function and not only have 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 saved production cost and convenient transport.

Main public address woofer 2 described in the utility model, main public address high pitch loudspeaker 3, return and listen medium and low spectrum loudspeaker 4 and return and listen high pitch loudspeaker 5, can use the loud speaker of other types such as full frequency speaker, coaxial loudspeaker, Squawker, super woofer to substitute; Described main public address woofer 2, main public address high pitch loudspeaker 3, return and listen medium and low spectrum loudspeaker 4 and return and listen the mode arranged evenly of high pitch loudspeaker 5 to include but not limited to be up and down or left and right arranged distribution, and take other arrangement modes such as diagonal angle arrangement.

In conjunction with most preferred embodiment, the utility model is described above, but the utility model is not limited to the embodiment of above announcement, and should contains the various amendments of carrying out according to essence of the present utility model, equivalent combinations.
