Embodiment Construction

[0016] The embodiments of the present invention will be described below with reference to the related drawings. In the figures, the same reference numbers refer to the same or similar components or method flows.

[0017] It must be understood that words such as "comprising" and "comprising" used in this specification are used to indicate the existence of specific technical features, values, method steps, operation processes and / or components, but do not exclude the possibility of adding Further technical features, values, method steps, job processes, components, or any combination of the above.

[0018] It must be understood that when an element is described as being "connected" or "coupled" to another element, it can be directly connected or coupled to the other element, and intervening elements may be present. In contrast, when a component is described as being "directly connected" or "directly coupled" to another component, there are no intervening components present.

Abstract

The wireless earphone comprises an antenna, a plurality of form matching circuits, a radio frequency switch circuit, a wireless chip, a port matching circuit matched with the wireless chip in impedance, an antenna matching circuit matched with the antenna in impedance, a circuit board comprising a feeding point and a grounding point, a feeding connector and a grounding connector. The plurality of form matching circuits are respectively matched with the impedance of the antenna; the radio frequency switch circuit is electrically connected with a form matching circuit based on the control signal, and the form matching circuit electrically connected with the radio frequency switch circuit is grounded; after the wireless earphone is started, the wireless chip outputs different control signals to control the radio frequency switch circuit to be electrically connected with the different form matching circuits, so that the intensity indication value of the received signal of each channel in the preset channel range is detected through the antenna electrically connected with the different form matching circuits; and when the detection result is judged to meet the default condition, the radio frequency switch circuit is kept electrically connected with the current form matching circuit. Therefore, the anti-interference capability is improved.

Description

technical field [0001] The present application relates to the field of communication technologies, and in particular, to a wireless headset. Background technique [0002] As wireless earphones are becoming more and more popular in the market, people have higher and higher requirements for the appearance design and function of wireless earphones. Among them, the appearance design must be small enough to be easy to wear, but the more functional requirements, the more electronic devices need to be added, squeezed into the space where the antenna can be set, so that the design of the antenna is limited, resulting in poor OTA test performance of the antenna and The direction map is poor, which causes the problem of poor user experience. [0003] In addition, the circuit board area used in miniaturized wireless earphones is very small (about 2.0 square centimeters or less), resulting in (1) Switch Mode Power Supply (SMPS) that generates high-order harmonic noise and highly sensit...
