Description

  The present invention relates to a wireless earphone, and more particularly to a wireless earphone that can transmit and receive audio from an electronic device by wireless connection to the electronic device and can wind a cord in both directions.

  Many modern people have at least one portable electronic device, for example, a portable electronic device such as a mobile phone, a tablet personal computer, or a game machine. The user almost listens to the sound through earphones or headphones so as not to disturb other people. However, the earphones and headphones connected to the electronic device are inconvenient to put together the cords, and there is a risk of damaging the earphones, headphones or electronic devices by pulling the cords.

  In the wireless earphone according to Patent Document 1 (Taiwan Utility Model Public Notice No. M256036), since the wireless earphone is worn by hooking the hook on the user's ear, the entire wireless earphone can be heard only by one ear. There is a drawback that the weight of the ear is only applied to one ear, the ear is painful and cannot be worn for a long time.

In a conventional bidirectional cord winding holder, for example, a bidirectional cord winding holder according to Patent Document 2 (Taiwan Patent Publication No. I285184), a spiral spring is used so that the cord can be easily pulled out and stored. A design that gives elastic return force to the cord take-up holder, a design that winds two cords around the rotating body in opposite directions, and a design that constitutes the positioning means by the protruding portion and the stopper portion are adopted.
Conventional code positioning methods, for example, Patent Document 3 (Taiwan Utility Model Announcement No. 510365), Patent Document 4 (Taiwan Utility Model Announcement M2633681), Patent Document 5 (Taiwan Utility Model Announcement M321426) In Patent Document 6 (Taiwan Utility Model Public Notice No. M324056), ratchets, picks, rails, steel balls, etc. are used as positioning means for the cord winding holder.
However, when a circuit board, electric wire, or the like is installed in a conventional cord take-up holder, some elements may rotate, causing cord pulling or poor component contact.

In the present invention, the numbers of the convex portions 2114, the fixing members 2115, and the stopper blocks 2116 are not particularly limited.

  As shown in FIG. 1, the electronic component kit 30 includes a circuit board 31, a transmission / reception chip 32, a battery 33, a fine movement switch 34, an electrical connector 35, a light emitting element 36, and a microphone 37. As shown in FIGS. 1 and 5, the battery 33 is installed on the battery seat 2122 of the annular plate 212. The circuit board 31 is electrically connected to the battery 33. The transmission / reception chip 32 is installed between the circuit board 31 and the battery 33. The fine movement switch 34, the light emitting element 36, and the microphone 37 are installed on one surface of the circuit board facing the upper lid 22. The button 222 corresponds to the fine movement switch 34. When the user presses the button 222, the fine movement switch 34 operates to transmit an instruction. The light emitting element 36 corresponds to the light transmission hole 224 and is lit to present the usage state of the wireless earphone 1 to the user. The microphone 37 corresponds to the sound collection hole 223 and is used for allowing a user to perform recording or a telephone call. The electrical connector 35 is installed on the other surface of the circuit board 31, and can charge the battery 33 or transmit information to the wireless earphone 1. According to the above-described structure, the electronic component kit 30 can rotate according to the rotating housing 20. In this embodiment, the transmission / reception chip 32 is a Bluetooth chip, and the light emitting element 36 is an LED chip.

  As shown in FIG. 3, the spiral spring 40 is wound around the outer periphery of the fixed column 12, a part of which is installed between the stopper block 2116 and the side wall 2111, and one end of which is one side of the stopper block 2116. The other end is fixed to the locking groove 122 of the fixed column 12. Since the spiral spring 40 can be pulled and contracted while rotating according to the rotation of the rotary housing 20, an elastic return force can be applied to the rotary housing 20.

  As shown in FIG. 5, the earphone cord 50 is divided into a left earphone cord and a right earphone cord. One of the left earphone cord and the right earphone cord is wound around the cup portion 211 in the clockwise direction and the other in the counterclockwise direction. As shown in FIGS. 2, 3 and 5, one end of each of the left earphone cord and the right earphone cord is inserted through a different opening 2113, whereby a part of the earphone cord 50 has a convex portion 2114 and a side wall. 2111 and fixed to the fixing member 2115. The plurality of electric wires extending from the earphone cord 50 are inserted through the electric wire hole 2117 of the side wall 2111 and the electric wire hole 2123 of the annular plate 212 and are extended in the direction of the upper lid 22 and are electrically connected to the circuit board 31. The As shown in FIG. 6, the other end of the earphone 50 is connected to the speaker unit 51 through the lower lid 11. One of the two speaker units 51 may be changed to a sound collecting microphone (not shown). According to the above arrangement, the left earphone cord and the right earphone cord can be pulled or shrunk simultaneously. By pulling the earphone cord 50, the cup portion 211 is interlocked and rotated around the fixed column 211, whereby the entire rotary housing 20 and the electronic component kit 30 are also interlocked and rotated. In addition, when the earphone cord 50 does not have an accurate length, the wiring method in which the earphone cord 50 is inserted through the electric wire holes 2117 and 2113 has a margin for accommodating the earphone cord 50 having a long length, and thus the earphone cord 50 directly on the circuit board 31 It can be accommodated more effectively than the system connected to.

  As shown in FIG. 1, the positioning kit 60 is installed between the rotary seat 21 and the lower lid 11. The positioning kit 60 may be composed of one or a combination of a ratchet, a pick, a rail, a steel ball, and the like.

  As shown in FIG. 3, the positioning kit 60 fixes the rotary housing 20 at a predetermined position in the fixed component kit 10. As a result, the user can determine the length of the earphone cord 50 to be exposed to the outside of the lower lid 11. In addition, when the earphone cord 50 is fully pulled out, the earphone cord 50 is wound around the original position by rotating the rotary housing 20 to the original position by the elastic return force of the spiral spring 40. Thereby, most of the earphone cord 50 is wound around the cup portion 211 so as not to be exposed to the outside of the lower lid 11, so that damage due to entanglement or pulling of the earphone cord 50 can be prevented.

As described above, the present invention has the following effects.
1. Since the electronic component kit is installed on the battery seat of the rotating housing, when the rotating housing is rotated in conjunction with pulling out the earphone cord, the electronic component kit can be rotated in conjunction with it, and the cord can be prevented from being pulled. .
2. The wiring system in which the earphone cord is inserted through the wire hole of the annular board and the wire hole of the side wall can provide a margin for accommodating the earphone cord having a long length, so that the accuracy requirement of the length of the earphone cord can be reduced.

  What has been described above is merely a preferred example of the present invention, and does not limit the scope of the utility model registration request of the present invention. Any equivalent changes and additions made on the basis of the description and drawings of the present invention shall be included in the scope of the utility model registration request of the present invention.
