Multi-function earphone

The invention relates to an earphone, in particular to a multi-function earphone capable of connecting a wired or wireless transmission interface.

Headphones are very common audio output tools in daily life. The common earphone types are roughly divided into two types according to the mode of signal transmission. One is a wired connection, that is, a 2.5mm plug or a 3.5mm plug. Connected to the electronic device, the other is a wireless connection, that is, the earphone is connected to a wireless transmission interface such as Bluetooth, and the wireless signal is transmitted with the electronic device, and in actual experience, the quality of the earphone is good or bad at the price. The drop is quite large. However, for different occasions, it is necessary to prepare at least two sets of headphones of the same sound quality, one is a wired connection and the other is a wireless connection, which is easy to cause a large expenditure, and It is inconvenient to carry and save the headset.

Therefore, some companies have developed patents such as the Republic of China Patent Gazette, Bulletin No. M485581, and the patent name "Headphones", including the base of the earphone that is electrically connected to the cable, and the base of the earphone for interfacing the audio. The signal is converted into a sound earphone unit, and the earphone unit is assembled on the earphone base, wherein the earphone base is provided with a plug portion, the plug portion includes an outer conductor and the outer conductor a conductor disposed at intervals, the earphone unit includes a sound amplifying portion, and the sound amplifying portion includes an abutting portion electrically connected to the plug portion, the pair The connecting portion includes an outer guiding portion electrically connected to the outer conductor, and an inner guiding portion electrically connected to the inner conductor.

However, in actual use, after the earphone is worn to the ear, the user must adjust the position of the earphone so that the cable can fall more naturally. In the manner of adjustment, the entire earphone must be removed from the ear and then re-fitted. As the user moves, walks, lifts, etc., the position of the cable is often placed on the shoulder, neck, arm, etc. of the human body. Although the cable can be manually stretched to a state of natural hanging down, However, the part where the cable and the earphone are connected is still to be re-disassembled and then matched once, resulting in inconvenience in use.

Furthermore, it can be seen from the contents of the specification that "the abutting portion 33 includes a cylindrical tubular outer guiding portion 331 and a cylindrical tubular inner guiding portion 332 located between the outer guiding portions. One end of the portion 31 is recessed inwardly to form a receiving recess 310. The mating portion 33 is entirely received in the receiving recess 310 and electrically connected to a sound converting mechanism (not shown) located inside the sound amplifying portion 31. The earphone base The upper connecting portion 23 is correspondingly inserted into the abutting portion 33, the outer conductor 231 is correspondingly inserted into the outer guiding portion 331, and the inner conductor 232 is correspondingly inserted into the inner guiding portion 332", the earphone base 2, the connection structure with the earphone unit 3 is from the structure of the plug portion 23 and the mating portion 33, and the outer conductor 231 is correspondingly inserted into the outer guide portion 331, and the inner conductor 232 is correspondingly inserted into the inner guide portion 332. In addition to the combination, it also directly has the function of audio signal transmission. However, during the transmission of the audio signal, the friction between the metal conductors, the contact area between the contact faces, the flatness, etc., will cause the audio signal to be transmitted. In the process of generating unnecessary impurities Interference, as far as this patent is concerned, although the plug portion 23 and the butt portion 33 are not combined in which metal connection is used, the metal objects are more likely to have uneven contact under long-term friction. Face, on these uneven contact surfaces, is the source of noise interference.
