Abstract
A folding dynamic stereo earphone is a headphone for stereo sound appreciation. Compared with the prior art, the folding dynamic stereo earphone has good acoustic performance, convenient carry and storage. The earphone has the main feature of: an adjustable stand frame (2) can rotate around the shaft of hinges and fold, and simultaneously, can adjust elastic force by adjusting different positions of an elastic extension spring stuck on a beam for the best comfort. The structure not only can be used for common wire earphones, but also can be used for manufacturing radio earphones, head-radios, totally enclosed stereo earphones, etc.
Description
The present invention is the dual track headphone that a kind of support can fold.
The form of existing dual-channel headphone has two kinds: the wear-type of steel disc support and " the mini formula " that be hidden in the ear.But these two kinds of earphones all respectively have shortcoming: the wear-type volume of steel disc support is big, the wire rack out-of-shape, thereby the time spent does not carry, collects all inconvenient; " mini formula " though easy to carry because the vibrating membrane area is little, make acoustic efficiency, mainly be that frequency response degenerates.This device designs in order to solve this contradiction, and the frequency response that has both kept headphone is wide, the advantage that distortion is little, and it is little to have absorbed " mini formula " volume again, portable strong point.Simultaneously, the manufacturing process of this earphone is also very simple, and the elastic force when wearing is adjustable, and a kind of specification just can adapt to proprietary needs.
Be described in detail below in conjunction with the structure of accompanying drawing this device.
Fig. 1 is the profile overall pattern when wearing.
Collapsible dual-channel headphone consists of the following components: earphone 1., adjustable stand 2., crossbeam 3., the elasticity extension spring 4., hinge 5., draw-in groove is 6..2. adjustable stand can rotate around hinge axle 5., can Dai Yutou after outwards forwarding certain angle on, 4. elasticity extension spring at this moment is tightened up, and produces certain resilience force, makes generation frictional force between entire headset and people's the head, ear and fixes unlikely landing.6. crossbeam has draw-in groove on 5., regulates the elasticity extension spring and 4. 5. goes up the chief's position and adjustable stand length 2. at crossbeam, can make earphone 1. people's ear be produced suitable preload pressure adapting to the head of different people, and make the sensation the most comfortable when wearing.Adjustable stand 2. be support be again a leaf spring, with transfer elastic extension spring elastic force 4., and elastic range is increased.Its structure is identical with the wear-type two-channel sterearphone of general steel disc support.
Fig. 2 is a crossbeam structure chart 3..
Fig. 3 is the structure chart with the elasticity extension spring of steel wire manufacturing.4. the elasticity extension spring also can replace with rubber band, is installed in adjustable stand by rights and 2. 3. goes up with crossbeam.
This device not only can be used for the transformation of general dual-channel headphone, also can be used for the aspects such as wireless headset, head holding radio; After suitably amplifying reinforcement, also can be used for the bigger totally enclosed type dual-channel headphone of volume.
Claims (2)
1, a kind of by earphone 1., adjustable stand 2., crossbeam 3., the elasticity extension spring 4., hinge 5., the collapsible dual-channel headphone that 6. draw-in groove is formed is characterized in that 2. adjustable stand can rotate around hinge axle 5.; 4. the tensile elasticity extension spring produces an opposite force and earphone can be worn on the number of people when outwards turning to certain angle.
2, the described collapsible dual-channel headphone of claim 1, it is characterized in that the elasticity extension spring 4. may be stuck in crossbeam 3. go up different draw-in grooves 6. among.
