Description

Technical Field

[0001] The utility model discloses an e-sports headset, in particular to a special antenna structure for a head-mounted e-sports headset, belonging to the technical field of consumer electronic products. Background Technique

[0002] Due to their convenience and comfort, wireless headsets have become a popular choice for many people in their daily life and entertainment activities in recent years. Regardless of the form of wireless headset, the antenna is an essential and important component. The antenna design and performance of radio e-sports headsets have an important impact on the sound quality, latency and usage range of the headsets.

[0003] Currently, the antennas of wireless headsets usually include two types: built-in antennas and external antennas. Many wireless headsets use built-in antennas, which are usually integrated in the ear cups or casings of the headsets. This design can keep the appearance of the headsets simple, but may affect the signal strength and coverage. Some high-end headsets may be equipped with detachable or fixed external antennas, which can enhance signal transmission and improve the sound quality and latency performance. The built-in antenna is still the mainstream choice for wireless headsets.

[0004] When designing the antenna of a wireless headset, its effective distance and anti-interference ability are usually considered. Since metal objects and walls will interfere with wireless signals, it is best to avoid using the headset in these environments when using it. Even so, when using a wireless headset, there are still intermittent or delayed situations, which may be caused by signal interference from other wireless devices (such as routers and Bluetooth devices).
