[0004] 2. Description of the Prior Art

[0005] Recently, electronics technology has known a rapid and a spectacular development leading to an availability of more inexpensive electronic products to consumers. For example, earphones are increasingly utilized and improved, with the development of portable acoustic appliances, from headphones, earplug earphones to clip-on earphones. Particularly, clip-on earphone devices have become more and more popular and a great variety of such devices have been developed. A clip-on earphone device has a clip-on structure such that the clip-on earphone device can be fixed on the ears. However, every user is different in their head shapes, the face profiles and even the ear shapes. Free adjustment of the earphone position of the conventional clip-on earphone device is not available, and therefore it is usual that the user finds his purchase does not match with his/her face profile. As a result, the sound quality is not as expected and the user may feel uncomfortable. On the other hand, the clip-on earphone device makes people who wear glasses inconvenient and uncomfortable. Moreover, the conventional clip-on earphone device is not removable to be attached to the framework for a headphone. In this aspect, it is not flexible.

[0006] Taiwan Patent Publication No. 474541 entitled “Improved clip-on earphone/microphone” discloses a prior art, as shown in FIG. 1.

[0017] FIG. 6 is an exploded view showing an earphone of the present invention.

[0018] The present invention providing a clip-on earphone can be exemplified but not limited by the preferred embodiment as described hereinafter.

[0019] Please refer to FIG. 2 and FIG. 3, which are an exploded view and a perspective view, respectively, showing a clip-on earphone device according to a preferred embodiment of the present invention. The clip-on earphone device comprises: a clip-on member 1; a connecting member 2; and an earphone 3. As shown in FIG. 2, a connecting base 12 having a door is coupled via a resilient repositioning mechanism 11 to the C-shaped clip-on member 1. A chute 121 is disposed on the connecting base 12. A sliding element 21 for connecting with the chute 121 is provided at one end of the connecting member 2. The other end of the connecting member 2 is attachable to the earphone 3 via a positioning mechanism 4.

[0020] Moreover, the resilient repositioning mechanism 11 comprises: a spring element 13, a fastening element 14 and a case 15. A flange 16 having an axis 17 is disposed on the clip-on member 1. An eminent portion 171 is formed near the flange 16 on the axis 17. A ring-shaped groove 172 is formed on the other end of the axis 17. At the tip of the axis 17, a trench 173 is provided. Therefore, a channel 122 having a trench 123 is formed such that the axis 17 can be inserted into the connecting base 12. Furthermore, a concave cut 124 is formed on the connecting base 12 facing the axis 17. Positioning portions 131 and 132 on both ends of the spring element 13 are bended inwards to the axis 17 and outwards, respectively, such that the spring element 13 is coupled to the axis 17. The positioning portion 131 is fitted with the trench 173, while the positioning portion 132 is fitted with the trench 123. The axis 17 and the ring-shaped groove 172 are exposed outside the connecting base 12. The fastening element 14 is attached to the ring-shaped groove 172 and the case 15 is attached to the axis 17 such that a clip-on earphone device is completed. Moreover, when the user rotates the connecting base 12 outwards, the eminent portion 171 and the concave cut 124 are used to limit the rotation angle of the connecting base 12; meanwhile the spring element 13 pushed the connecting base 12 back to an original position.

[0021] Accordingly, the opening end of the chute 121 and the flange 16 contact so as to prevent the connecting member 2 from falling from the opening end of the chute 121. Similarly, the user only has to rotate the connecting base 12 for a certain angle such that the flange does not block the opening of the chute 121. Therefore, the connecting member 2 is easily detached from the connecting base 12.

[0022] The connecting member 2 is connected to the earphone 3 via the positioning mechanism 4. A ring-shaped groove 22 is provided at the bottom of the connecting member 2 such that the earphone 3 rotates in a limited angle range. However, a base 31 and a fixing member 32 corresponding to the ring-shaped groove 22 are provided in the earphone 3, in which the fixing member 32 is solidly attached to the base 31. A concave surface 311 is formed on the base 31 and a concave surface 321 is formed on the fixing member 32, such that a compartment is formed by the concave surfaces 311 and 321. Moreover, on the concave surfaces 311 and 321, there are provided flanges 312 and 322, respectively, such that the flanges 312 and 322 can be clipped onto the ring-shaped groove 22. A trench 23 is formed on the connecting member 2. An eminent portion 323 corresponding to the trench 23 is formed on the fixing member 32 so as to limit the angle range in which the earphone 3 rotates.

[0023] According to the present invention, the clip-on earphone device is advantageous in that the position of the earphone can be adjusted and the earphone can rotate within a limited angle range in accordance with the face profiles of the users, as shown in FIG. 4.

[0024] Furthermore, the connecting member 2 and the earphone 3 can be attached to a headphone framework 5 via a connecting member 51, thus forming a headphone, as shown in FIG. 5.

[0025] Moreover, please refer to FIG. 6, which is an exploded view showing an earphone of the present invention. In FIG. 6, the earphone comprises a base 33, a driver 34, a body 35 and a cap 36. The base 33 and the body 35 can be combined to form a compartment so as to accommodate the driver 34. A ring-shaped groove 351 is formed on the body 35. Furthermore, the cap 36 can be fixedly attached to the body 35 or be flexibly attached to the body 35 by using a buckle member 37 such that the case 36 is removable and changeable.

[0026] More particularly, the buckle member 37, as shown in FIG. 6., comprises: a ring-shaped clip 361 having a flange 362. The ring-shaped clip 361 corresponds to the ring-shaped groove 351 such that the cap 36 can be attached to the body 35.

[0027] According to the above discussion, the present invention discloses a clip-on earphone device, in which the position of the earphone can be adjusted and the earphone can rotate within a limited angle range in accordance with the face profiles of the users. Therefore, the present invention has been examined to be novel, unobvious and useful.
