Electronic device

The present invention relates to an electronic device, and more particularly to an electronic device having a telescopic earphone.

With the continuous updating and development of technology, electronic devices such as mobile phones, personal digital assitants (PDAs) and notebook computers have become a necessity for people's work and daily life. In some special occasions, people generally listen to the music and sound played by the portable electronic device through the earphone, so when carrying the portable electronic device, the earphone must be carried at the same time.

However, each time you use the headphones, you must take care to avoid the long earphone cords tangled together. After use, you must carefully roll up and store them, which is very inconvenient. In addition, wireless headphones, such as Bluetooth headsets, are also appearing on the market. However, since the Bluetooth headset is relatively large in size, it is extremely inconvenient to listen to when it is worn.

In view of the above, it is necessary to provide a portable electronic device with a telescopic earphone that can accommodate the earphone in the portable electronic device.

An electronic device includes a body, a circuit board mounted in the body, an earphone, and a receiving device. The earphone includes a connecting wire and an earphone head. One end of the connecting wire is electrically connected to the circuit board, and the other end is connected. In the earphone head, the receiving device includes a receiving portion for receiving the connecting wire therein and a receiving slot communicating with the receiving portion, the ear The head is fixed and received in the receiving slot. When the earphone is needed, the earphone head is disengaged from the receiving slot, and the connecting line is extended by the receiving portion.

Compared with the prior art, the portable electronic device with the earphone can be housed in the body of the portable electronic device, and enables people to listen to the portable electronic device by using the earphone anytime and anywhere in the busy daily life. Music and sound, etc. In addition, the portable electronic device with headphones can effectively avoid the loss of the earphone.

The shelter The device is disposed on the body 11. The earphone 13 is electrically connected to the circuit board.

The body 11 is substantially a rectangular plate body, and includes a top end 111, a bottom end 112, and a side wall 113 connecting the top end 111 and the bottom end 112. A display screen 114 for displaying information is disposed at a central portion of the surface of the body 11. The body 11 is provided with a plurality of buttons 115 for inputting information adjacent to the bottom end 112.

The circuit board is provided with a data transmission module (not shown). The data transmission module is fixedly and electrically connected to the earphone 13.

The receiving device is disposed adjacent to the display screen 114 in the body 11 of the mobile phone 10 for receiving the earphone 13 . The receiving device includes a receiving portion 121, a rotating shaft 122, a rotating tube 123, a spring 124, a button 125, a button slot 126 and a receiving slot 127.

The receiving portion 121 is an accommodating space for partially accommodating the earphone 13 therein. The rotating shaft 122 is fixed or integrally formed with the body 11 of the mobile phone 10. The drum 123 is rotatably sleeved on the rotating shaft 122. The spring 124 is a torsion spring. One end of the spring 124 is fixed on the rotating shaft 122, and the other end is fixed on the rotating cylinder 123. The spring 124 provides an elastic force for the rotation of the drum 123 relative to the rotating shaft 122. The button slot 126 is formed on the side wall 113 of the body 11 adjacent to the receiving portion 121 and communicates with the receiving portion 121. The button 125 has an operating portion 128 and a latching portion 129 connected to the operating portion 128. The operating portion 128 is slidably mounted in the button slot 126. The catch portion 129 abuts the earphone 13 wound around the drum 123.

The receiving groove 127 is formed on the side wall 113 adjacent to the button groove 126 and communicates with the receiving portion 121. The receiving groove 127 is a trough having a "T" shape, and includes a first cavity 1271 and a second cavity 1272 communicating with the first cavity 1271. The second The cavity 1272 has a circular bottom wall 1273 and an annular peripheral wall 1274. The circular bottom wall 1273 extends through a circular hole 1275 so that the earphone 13 is wound around the rotating cylinder 123 through the circular hole 1275. The annular peripheral wall 1274 protrudes from the bottom wall 1273 with a resilient piece 1276. The elastic piece 1276 is smoothly extended from one end to the other end, and forms a peak 1277, and a card slot 1278 is formed between the peak 1277 and the bottom wall 1273.

The earphone 13 includes a plastic connecting wire 131 and an earphone head 132. The connecting wire 131 is wound on the rotating drum 123, and one end thereof is connected to the data transmission module of the circuit board, and the other end is exposed outside the body 11 through the receiving groove 127 and connected to the earphone head 132. The earphone head 132 is received in the receiving groove 127 of the receiving device. The earphone head 132 is substantially a "T" shaped cylinder, and includes a listening portion 1321 and a connecting portion 1322 connected to the listening portion 1321. The listening portion 1321 is configured to be inserted into an ear hole of a person. The shape and size of the listening portion 1321 are substantially equivalent to the shape and size of the first cavity 1271. The shape and size of the connecting portion 1322 are substantially the same as the shape and size of the second cavity 1272, and are used for receiving and fixing the earphone head 132 in the receiving groove 127. An annular block 1323 protrudes outwardly from the peripheral side of one end of the connecting portion 1322 for holding in the card slot 1278.

When assembling, the drum 123 is first sleeved on the rotating shaft 122; then the rotating shaft 122 is fixed to the body 11 by welding or the like; then one end of the spring 124 is fixed to the rotating shaft 122 or the body 11, and the other end is The wire is attached to the drum 123, and the connecting wire 131 of the earphone 13 is wound around the rotating plate 123, and one end thereof is electrically connected to the circuit board, and the other end is exposed to the outside of the body 11 through the receiving groove 127; The headphone head 132 is mounted on the connecting wire 131 to complete the assembly.

When the earphone 13 is used to answer the phone or music, first use the external force to pull out the connecting wire 131 to a suitable length. At this time, the spring 124 has an elastic force; then, the button is toggled. The operating portion 128 of the button 125 causes the latching portion 129 of the button 125 to abut against the peripheral wall of the drum 123 around which the connecting wire 131 is wound. Thus, the latching portion 129 and the rotating drum 123 around which the connecting wire 131 is wound A frictional force is generated between the peripheral walls to balance the spring force of the spring 124, so that the connecting wire 131 is kept in a stable state, and the user can easily insert the earphone head 132 of the earphone 13 into the ear hole of the person to answer the call. Or music.

Referring to FIG. 3, when the earphone 13 needs to be retracted on the body 11, the operation portion 128 of the button 125 is simply pulled out of the connecting portion 131 to be unwound on the unwinding portion of the drum 123. The pull-out portion (not shown) of the wire 131 is re-wound on the drum 123 under the elastic force of the spring 124, and the earphone head 132 is received in the receiving groove 1037. At this time, the block 1323 passes over the peak 1277 of the elastic piece 1276. The card is held in the card slot 1278.

Referring to the second preferred embodiment of the portable electronic device of the present invention shown in FIG. 4 to FIG. 6 , the mobile phone 20 has the same structure as the mobile phone 10 , and includes a body 21 and a circuit board (not shown). a receiving device 22 and an earphone 23, the circuit board is disposed in the body 21, the receiving device 22 is disposed on the body 21, the receiving device 22 includes a receiving slot 227, and the receiving slot 227 includes a first a cavity 2271 and a second cavity 2272 communicating with the first cavity 2271.
