Abstract

The invention discloses an earphone circuit structure and communication equipment. The earphone circuit structure comprises an internal earphone circuit structure located in the terminal. The internalearphone circuit structure comprises an earphone seat, a codec, a first filtering module and a second filtering module. The first end of the first filtering module is connected with the earphone seat, and the second end of the first filtering module is connected with the first end of the second filtering module; And the second end of the second filtering module is connected with the codec. The earphone circuit structure disclosed by the embodiment of the invention can completely cover the propagation path of interference signals in the earphone circuit in the terminal, and meanwhile, the first filtering module and the second filtering module are mutually combined, so that the filtering efficiency is improved.

Description

technical field [0001] Embodiments of the present invention relate to the field of electronic technology, and in particular to earphone circuit structures and communication equipment. Background technique [0002] As the main accessory of the communication equipment, the audio performance of the earphone directly affects the user experience. If the user is in an environment with weak communication signals, it is easy to hear interference signals in the headset. [0003] At present, the method for eliminating the interference signal in the earphone is to add filtering devices or shielding materials to the communication equipment. [0004] However, there are many ways to distribute earphone sockets, and different ways of distribution will generate different interference signals. In the prior art, there is no clear indication of where to add filter components or shielding materials in the communication equipment, and where to add filter components or shielding materials. The ...
