Description

A kind of rotating member of Rotary Speaker

Technical field

The utility model relates to a kind of member of audio amplifier, relates in particular to a kind of rotating member of Rotary Speaker.

Background technology

Audio amplifier is not only the loud speaker of stereo set now, and in today of electroacoustic techniques development, good conglomeraties such as IP, communication, computer are all used audio amplifier widely, and audio amplifier form different style is each has something to recommend him.The stereo set that uses in home theater etc. mostly is vertical casing shape, and in small-sized audio amplifier, audio amplifier often also is fix desk-top, carries inconvenience, and the problem of the different audio amplifier angles of different acoustic effect requirements be can't resolve.The small-sized audio amplifier that also has some adjustable angle, it is to adjust angle by additional support, structure is comparatively complicated.

Summary of the invention

The utility model has mainly provided a kind of simple in structure, and connection and reasonable arrangement can rotate freely the rotatable sound box rotating member of angle on the direction parallel with loudspeaker; It is comparatively complicated to have solved the structure that exists in the prior art, carries technical problems such as inconvenience.

Above-mentioned technical problem of the present utility model is mainly solved by following technical proposals: a kind of rotating member of Rotary Speaker, the loudspeaker casing of audio amplifier is provided with rotating shaft, the main box of audio amplifier is provided with the hole of matching with rotating shaft, and the one side of loudspeaker casing is provided with a catch dorsad in the hole.By cooperating of the rotating shaft on the hole on the main box and the loudspeaker casing, make the loudspeaker casing in the plane parallel, to rotate by 180 degree with main box, the user can require to adjust angle according to the difference to the audio amplifier quality, can with the loudspeaker casing by rotary folding on main box, dwindle the volume of whole audio amplifier equipment, be easy to carry simultaneously; With after rotating hole cooperates, be stamped catch at rotating shaft, rotating shaft and hole better fit are linked together on the top of rotating shaft.

As preferably, described catch is circular, and its diameter is greater than the diameter in hole on the main box.The diameter of catch is greater than the diameter in hole, can work as after axle connects with the hole, snaps onto fixed connection shaft and hole on axle and the hole.

As preferably, described catch is provided with a stop bit projection.The setting of stop bit projection is for when the loudspeaker casing rotates, the maximum angle of control rotation, the angle of the rotation of the relative main box of loudspeaker casing is a 0-180 degree in the horizontal plane, the restriction anglec of rotation is in order to prevent irregular any rotation repeatedly, easily electric wire is twined back and forth, cause fractureing of electric wire, thereby audio amplifier was lost efficacy.

As preferably, be provided with the chucking projection at least one side of described stop bit projection.The chucking projection is arranged on a side of stop bit projection, is that the loudspeaker casing rebounds, and does not reach the final position for after preventing that the loudspeaker casing from rotating to maximum angle.

As preferably, the both sides in the hole on the main box of described catch outer rim are provided with two stop bit bearing pins, and the level height of two stop bit bearing pins differs the width of a stop bit projection.The stop bit bearing pin is corresponding with the stop bit projection, the height of two bearing pins does not wait, and is because the stop bit projection has certain thickness, in order to make that the anglec of rotation of loudspeaker casing just in time is 180 degree, so the height of two bearing pins that the outer rim in the hole of main box is provided with is inconsistent.

As preferably, on described catch, be provided with four apertures, four apertures are cross distribution at the catch center.Four apertures are the cross form and distribute, and have saved the space, also convenient processing.In four apertures, have two to be connecting hole, two be with the rotating shaft end face on the corresponding pin shaft hole of bearing pin.In the connecting hole, one is the connecting hole that adopts screw to be connected in rotating shaft and hole, and one is wire hole; Corresponding pin shaft hole, then one big one little, the differentiation of size is anti-in order to prevent the audio amplifier dress.

As preferably, described rotating shaft is a multidiameter, and the hole of Dui Ying main box is a shoulder hole with it, is provided with the strong point on the annular end face at the shaft shoulder place of rotating shaft.The setting of shoulder hole can be so that connection and location be better, and the number in hole is two, and promptly the number of loudspeaker casing is two, and two loudspeaker are a kind of configurations conventional and that use is maximum.The diameter in hole is 1cm-5cm, is provided with the strong point on the shaft shoulder annular end face of multidiameter, makes between main box and the loudspeaker casing to have slowed down frictional force for some contact, make rotate more flexible.

As preferably, in the gap in described rotating shaft and hole, be provided with O shape elastic ring, the sectional area of O shape elastic ring is greater than the sectional area in gap.The sectional area of O shape circle just is slightly larger than the sectional area in gap.Being arranged so that in hole and between centers formation of elastic ring closely cooperates, and after the anglec of rotation, rotating box just can maintain this angle like this, if axle and hole directly cooperate,, all make several times have more than is needed no matter be interference fits or interference fit, just will wear and tear, thereby rotating box can not be located.

As preferably, described rotating shaft end face is provided with bearing pin and aperture, and the number of bearing pin and aperture all is two, one of the diameter of described bearing pin big one little.The number of bearing pin and aperture all is two, the setting of bearing pin makes in order to be connected location usefulness with catch, two apertures, one is that rotating shaft is coupled together the connecting hole that is provided with by the Kong Houyu catch, another is that the electric wire in the main box is linked wire hole in the loudspeaker casing.

Therefore, the utlity model has simple in structure, connection and reasonable arrangement, easy to carry, can be in the parallel direction Rotate 180 degree of loudspeaker casing, the advantages such as angle that require to regulate casing according to difference to tonequality.
