Abstract

The utility model relates to that two opposing wall panels are arranged in a sounding case of a headphone, a plurality of sound outlet holes are arranged on an upper ring, a loudspeaker in the sounding case is arranged between the two wall panels, the periphery surface of the sounding case is provided with two trough openings which are respectively positioned on the out side edge of the two wall panels and are sheathed with a rotatable sound screen panel out of the two wall panels, an upper ring of the sound screen panel is provided with sound controlling holes corresponding to the sound outlet holes, and the side edge of the sound screen panel is projected with a pushing handle which perforates out of the trough opening of the sounding case and exposes out of the sounding case. The sound screen panel can rotate via pushing the pushing handle on the side edge of the sound screen panel, so as to control the sounding effect of the vigour before and behind the loudspeaker.

Description

Headphone

A kind of headphone, the sound that belongs to the sound equipment field sends, conduction or directed conventional method or weapon exercises.

General headphone lies in an arcuation and has the inner side edge installing sounding housing of wearing two ends, frame below of elasticity, this sounding housing is an oblate shape housing, in it, be equiped with loudspeaker, and on the opening of sounding housing, be set with an ear muff, the loudspeaker that are contained in the sounding housing connect with a lead with input plug, input plug is inserted on the delivery outlet of sound equipment, makes signal be imported the loudspeaker of earphone, and spread out of sound by loudspeaker.

The loudspeaker of general ear receiver, be installed in the sounding housing, and the effect of this housing only is latent root of Dahurian angelica loudspeaker, the quality of its pronunciation system is trapped among sound around the ear by the ear muff that is installed on the sounding housing, the sound and the external world are separated, its sound unroll and quality is fixing fruit, only can be by the control of the tuner on sound equipment tonequality, but the sound quality that loudspeaker itself send is uncontrollable for fixing fruit; For the higher people of tone sense, two ears such as can't obtain at one fruit.

Headphone go out audio fruit, imposing manner and back imposing manner before can being divided into, and imposing manner is the sound effect that loudspeaker the place ahead is gone out before the known headphone, the then powerful voice effect that then produces for the loudspeaker back side, still, these sounding housing two ends are open, and be fixing kenel, its effect of dispatching from the factory how, just can't change later, so can't cooperate individual's tone sense requiredly suitably to adjust, therefore have in the use and do not attain desirable part and have much room for improvement.

The purpose of this utility model provides and a kind ofly is provided with two relative wallboards in the sounding housing of headphone, and this wallboard is equiped with the screening soundboard outward, goes out the audio fruit by rotating the forward and backward imposing manner that hides soundboard may command loudspeaker.

Scheme of the present utility model be an arcuation and have elasticity wear that the inner side edge at two ends is equiped with the sounding housing below the frame, this sounding housing is an oblate shape housing, in it, be equiped with loudspeaker, and on the opening of sounding housing, be set with the ear muff of a flexibility, of the present utility model being characterised in that: in this sounding housing, be provided with two relative wallboards, be equipped with a plurality of senders thereon, aforementioned loudspeaker then are installed between two wallboards, periphery in the sounding housing is provided with two long rabbets again, and this two long rabbet lays respectively on the outer side edges of two wallboards, and outside two wallboards suit one rotary screening soundboard, be equipped with control sound hole on this screening soundboard with respect to aforementioned sender, and on the side that hides soundboard, convex with a handle, this handle is passed by the long rabbet of sounding housing, and the handle that hides on the soundboard side is passed in the outside of exposing the sounding housing, and hiding soundboard can rotate.

The utility model has the advantages that, owing in the sounding housing of headphone, be provided with two relative wallboards, and this wallboard is equiped with the screening soundboard outward, go out the audio fruit by rotating the forward and backward imposing manner that hides soundboard may command loudspeaker, so, be fit to the different tone sense requirement of various people, adjust its most satisfied glad music pleasant sensation of repaying.

The utility model has following accompanying drawing and accompanying drawing is made brief description.

drawing

1,2, an arcuation and have elasticity wear that the inner side edge at two ends is equiped with sounding housing 2 below the frame 1, this sounding housing 2 is an oblate shape housing, in it, be equiped with loudspeaker 3, and on the opening of sounding shell 2, be set with the ear muff 4 of a flexibility, of the present utility model being characterised in that: in this sounding housing 2, be provided with two relative wallboards 21, be equipped with a plurality of senders 211 thereon, 3 on aforementioned loudspeaker are installed between two wallboards 21, periphery in sounding housing 2 is provided with two long rabbets 22 again, and this two elongated slot 22 lays respectively on the outer side edges of two wallboards 21, and outside two wallboards 21 suit one rotary screening soundboard 5, be equipped with control sound hole 51 on this screening soundboard 5 with respect to aforementioned sender 211, and on the side that hides soundboard 5, convex with a handle 52, this handle 52 is passed by the long rabbet 22 of sounding housing 2, and exposes the outside of sounding housing 2.

According to above-mentioned structural feature, if that will adjust imposing manner and back gas imposing manner before the loudspeaker 3 goes out the audio fruit, by passing handle 52 shield 5 is rotated, make control sound hole 51 skews on it, make the outlet of sender 211 dwindle or amplify, as shown in Figure 4, so imposing manner and back imposing manner goes out the audio fruit before the control loudspeaker 3, make it comply with individual's tone sense demand, do the adjustment of appropriateness, therefore, preferable use elasticity is arranged just.

Because the screening soundboard 5 at loudspeaker 3 the place aheads or rear can distinctly be adjusted, and when the screening soundboard 5 of adjusting loudspeaker 3 rears, sender 211 on the rear wallboard 21 is amplified or dwindle, and then imposing manner becomes big or diminishes before making, otherwise, if adjust the screening soundboard 5 in loudspeaker 3 the place aheads, sender 211 on the wallboard 21 that is positioned at the place ahead is amplified or dwindle, can make the back imposing manner become big equally or diminish, so, regulate and control two simultaneously and hide soundboard 5, with the different output imposing manner of crossbar transistion, required to adapt to the individual.

In addition, on the lateral surface of two long rabbets 22 of sounding housing 2, scale must be set, make its signable go out before the output size of imposing manner or back imposing manner, the user is clear to find out whether the imposing manner adjusting out is that it is required and can allow, therefore, it has better ease of use.
