Earphone with an antenna

Abstract

The utility model provides an earphone with an antenna. The earphone comprises a plug, a signal line and earphones. The plug comprises an insulating stand and a plug terminal extending from one side of the insulating stand. The plug terminal at least includes a signal contact and a common contact. The plug terminal is electrically connected to a first signal line which at least comprises an inner core lead composed of a signal line and a grounding line. An outer coating layer with a function of the antenna and a grounding function is disposed at the periphery of the inner core lead. The other end of the first signal line is electrically connected to a switching circuit board with a housing, a second signal line and the earphones. The outer coating layer with the function of the antenna and the grounding function is arranged at the periphery of the inner core lead inside the first signal line, so that the whole earphone with the antenna is simple in structure and high in sensitivity, and exhibits a better anti-interference property.

Description

technical field [0001] The present invention provides an earphone with an antenna, especially an outer cladding layer of a conductor is provided on the periphery of the inner core wire in the first signal line of the earphone. In addition, the cladding layer has the functions of antenna and grounding at the same time, and is supplemented by a switching switch to Switch to antenna function or antenna plus earphone and microphone function, so as to achieve the effect of simple structure, high sensitivity, better anti-interference characteristics and switchable functions. Background technique [0002] With the development of wireless communication, from the early transmission and reception of broadcast channels with sound through electromagnetic waves, such as FM (Frequency Modulation) broadcast channel and AM (Amplitude Modulation) broadcast channel, it has evolved to the transmission and reception of audio and video through electromagnetic waves. broadcast channels, such as V...

Described FM antenna is a metal wire, is arranged in the earphone connection cable, switches to FM broadcast reception when mobile phone, FM antenna transmits the wireless signal of the FM frequency band that intercepts to mobile phone through earphone plug, but this kind of practice does not Unable to receive broadband signals in the digital TV band, and the received signal quality is poor and susceptible to interference, some manufacturers replace the above-mentioned metal antenna with a general transmission line and then connect it to a larger-area circuit board antenna for use, but the overall volume of this method It is too large to be used on the earphones of mobile phones, which are developing towards thinner and smaller. How to make the existing earphones with broadband signal antennas in the cables that can receive digital TV bands remains to be done in this industry. or redesigned to effectively address
