Problems solved by technology

[0003] In the existing technology, in order to ensure the signal transmission effect, the structure of the antenna is generally relatively large, so that the electronic product carrying the antenna is also relatively large, which does not meet the current development trend of miniaturization and densification of electronic products; but if the After the antenna is miniaturized, there are problems such as poor radiation distance due to the small surface area of ​​the radiator, low antenna efficiency and gain, etc.

Abstract

The invention discloses an independent external built-in antenna in an intelligent earphone, and relates to the technical field of earphones. The invention aims to solve the problem of how to ensure the use performance of an antenna in a light earphone. The antenna specifically comprises an antenna body and a communication module which are arranged on the inner wall of an earphone shell, the antenna body comprises a PCB, an elastic pin and a ceramic laminated antenna, one end of the elastic pin is arranged on one side face of the PCB, the ceramic laminated antenna is arranged on the inner wall of an extension handle of the earphone shell, the ceramic laminated antenna is connected with the PCB through the elastic pin, and the communication module is arranged on the PCB. The elastic pins and the ceramic laminated antenna are electrically connected with the PCB; the communication module comprises a wireless communication chip which is connected with the ceramic laminated antenna through an impedance matching circuit, and the wireless communication chip is arranged on one side surface of the PCB; and an impedance matching circuit is arranged between the signal output end of the PCB and the elastic pin. According to the invention, the size of equipment is not increased, and the antenna with stronger performance is also provided.

Description

technical field [0001] The invention relates to the technical field of earphones, in particular to an independent external built-in antenna in a smart earphone. Background technique [0002] Today, with the rapid development of Internet technology, electronic products with various types and functions have been integrated into all aspects of people's lives unconsciously, bringing convenience to people's daily life. At present, many electronic products that originally did not need to be connected to the Internet have realized more novel, interesting and practical functions by adding wireless communication modules and combining smart phones or voice recognition technology. Considering that there are many disadvantages in wired networking, existing electronic products with Internet of Things functions are all provided with a wireless communication chip and an antenna for receiving and transmitting wireless signals matched with the wireless communication chip. [0003] In the ex...
