Benefits of technology

This patent is about an earphone module that has a magnetic antenna framework, which makes it less likely to be affected by the human body and improves the efficiency of the antenna. The module has a conductive member connected to a first radiator and a second radiator, with a slot between them where an insulating member is placed to keep the appearance complete. This design results in an earphone module with a high efficiency and a complete antenna structure.

Problems solved by technology

Since the characteristic of electric antenna is open-circuited at an end at which the electric current is small and the electric field is strong, frequency band deviation is likely to occur due to the human body dielectric, which in turn affects the antenna efficiency.

Embodiment Construction

[0024]FIG. 1 is a schematic view illustrating the appearance of an earphone module according to an embodiment of the disclosure. Referring to FIG. 1, an earphone module 20 of this embodiment includes an antenna structure 100. The antenna structure 100 includes a first radiator 110, a second radiator 120, a conductive member 130, and a first insulating member 140. In the embodiment, the first radiator 110, the second radiator 120, the conductive member 130, and the first insulating member 140 of the antenna structure 100 collectively serve as at least a part of a shell 30 of the earphone module 20.

[0025]More specifically, in the embodiment, the second radiator 120 is a ground radiator. As shown in FIG. 1, the second radiator 120 serves as a large part of the shell 30 of the earphone module 20. The first radiator 110 is a main radiator and is located at one side of the second radiator 120 (e.g., the upper side in FIG. 1). A first slot S1 is formed between the first radiator 110 and th...

Abstract

An earphone module includes an antenna structure. The antenna structure includes a first radiator, a second radiator, a conductive member, and a first insulating member. The first radiator includes a feeding end. The second radiator includes a ground end, and a first slot is formed between the first radiator and the second radiator. The conductive member is connected to the first radiator and the second radiator. The first insulating member is disposed in the first slot. The first radiator, the second radiator, the conductive member, and the first insulating member collectively serve as at least a part of a shell of the earphone module.

Description

CROSS-REFERENCE TO RELATED APPLICATION[0001]This application claims the priority benefit of Taiwan application serial no. 110114720, filed on Apr. 23, 2021. The entirety of the above-mentioned patent application is hereby incorporated by reference herein and made a part of this specification.BACKGROUNDTechnical Field[0002]The disclosure generally relates to an earphone module, and in particular, to an earphone module with an antenna.Description of Related Art[0003]The antenna of a Bluetooth earphone generally has an electric antenna framework, and the antenna is disposed in a shell. Since the characteristic of electric antenna is open-circuited at an end at which the electric current is small and the electric field is strong, frequency band deviation is likely to occur due to the human body dielectric, which in turn affects the antenna efficiency.SUMMARY[0004]The disclosure is directed to an earphone module in which a shell of the earphone module forms a magnetic antenna framework. ...
