Description

Earphone with antenna

The invention provides an earphone with an antenna, in particular, a sheath outside the inner wire of the first signal line of the earphone is provided with a conductor covering layer, and the covering layer has both an antenna and a grounding function, and is supplemented by a switch. Switch to antenna function or antenna plus earphone and microphone function, in order to achieve the structure of simple, high sensitivity, better anti-interference characteristics and switchable function.

According to the development of wireless communication, the transmission and reception of sound channels such as FM (Frequency Modulation) broadcast channels and AM (Amplitude Modulation) broadcast channels through electromagnetic waves have evolved to transmit and receive sound through electromagnetic waves. And video broadcast channels, such as VHF (Very High Frequency) broadcast channels and UHF (Ultra High Frequency) broadcast channels. Various consumer electronic products have also been able to receive FM radio channels and AM broadcast channels from the early stage as the market demanded, and in recent years can further receive VHF channels and UHF channels.

In the early days, limited by the development of display technology, the above-mentioned consumer electronic products that can receive a variety of broadcast channels, such as radios and car televisions, have considerable size and are mostly installed on automobiles or locomotives, and cooperate with the consumer electronics. The antennas of the products are also quite large and most are placed on cars or locomotives. However, with the rapid development of display technology, digital TV functions have been integrated into the mobile phone of high-definition display screens in recent years, which has become one of the major trends in mobile phone development. The wireless signal specifications of digital TV specifications include DVBT (Digital Video). Broadcasting Television), ATSC (Advanced Television Systems Committee), ISDB (Integrated Services Digital Broadcasting), CMMB (China Mobile Multimedia Broadcasting System), etc., in order to enable the above-mentioned small consumer electronic products to play sounds from various broadcast channels through their display screens. And imagery, there is a need for an antenna that has a small size and can be carried around with the mobile phone that is thin, light, and short, and can receive electromagnetic signals from a variety of broadcast channels, but if the mobile phone is to receive digital television The antenna device in the band is integrated into the mobile phone, which will increase the size of the mobile phone and complicate the design of the mobile phone.

However, the conventional earphone is provided with an FM antenna for receiving the FM band wireless signal in the earphone connection cable between the earphone plug and the speaker, and a voice transmission line for transmitting the voice signal in the earphone connection line side by side with the FM antenna. The conventional earphone has the function of broadcasting the sound and receiving the wireless signal of the FM band. The FM antenna is a metal wire, which is disposed in the earphone connection cable, and is switched to the FM broadcast reception in the mobile phone. The FM antenna transmits the intercepted FM band wireless signal to the mobile phone through the earphone plug, but this method is Unable to receive the broadband signal of the digital TV band, and the received signal quality is poor and susceptible to interference. Some manufacturers replace the above metal antenna with a general transmission line and then connect it to a larger area of the circuit board antenna, but the overall volume of this method Larger, not suitable for today's headsets that are used in mobile phones with light and short development trends. How to make the conventional earphones have a broadband signal antenna that can be used to receive digital TV bands in the cable, which is still to be engaged in this industry. Redesigned to solve it effectively.

Therefore, in view of the problems and shortcomings of the earphones of the above-mentioned appliance antennas, the inventors collected and collected relevant data through various evaluations and considerations, and continuously tried and modified the research and development experience of the industry for many years. The invention of the antenna earphone was born.

The main purpose of the present invention is to include at least a signal contact and a common contact on the plug terminal, and the first signal line includes at least a inner core wire formed by the signal line and the ground line, and the inner core wire is provided with a peripheral portion. The antenna and the grounding function are not covered by the coating layer, and the coating layer may be formed by a wire material such as a Braid or a Spiral wire surrounding the inner core wire, and is passed through the first signal line. The periphery of the inner core wire is provided with a cover layer having an antenna and a grounding function at the same time, so that the whole body can achieve the functions of simple structure, high sensitivity and better anti-interference characteristics.

The secondary object of the present invention is to use the switch of the first signal line on the transfer circuit board to switch to the antenna function or the antenna plus the earphone and the microphone function, so that the user can select different functions according to the actual state. Use to achieve the effect of the switchable function.

Another object of the present invention is to provide a connector for the second signal line and the connector of the transit circuit board to be pluggable and disconnected, and to switch between the switches on the transit circuit board using the first signal line. When the antenna function is implemented, the connector of the second signal line can be removed from the connector of the transit circuit board, thereby forming the function of the individual antenna.

In order to achieve the above objects and effects, the technical means and the configuration of the present invention will be described in detail with reference to the preferred embodiments of the present invention.
