Description
Technical Field
[0001] This utility model relates to a television speaker, and more particularly to a wireless television speaker with a one-to-many broadcast mode and voice enhancement function. Background Technology
[0002] To improve the user's audio reception experience, wireless TV speakers are becoming increasingly widely used. Currently, wireless TV speakers generally consist of two parts: a transmitter and a receiver speaker. The transmitter connects to the TV to acquire audio signals, while the receiver speaker is equipped with an amplifier module to broadcast these audio signals as sound.
[0003] To save on audio cables and facilitate user customization of TV speakers, audio signals are currently transmitted wirelessly between the transmitter and receiver speakers. However, current wireless transmission solutions require a relatively long transmission time between the transmitter and receiver speakers, resulting in a significant delay between when the TV plays the audio and when the user hears it, which affects the user's viewing experience.
[0004] In addition, current wireless TV speakers are generally designed with one transmitter and one receiver speaker, which leads to a waste of transmitter resources when used in environments with multiple receiver speakers.
[0005] Therefore, how to design a wireless TV speaker with a broadcast one-to-many mode and language enhancement function, enabling one transmitter to communicate with multiple receiver speakers and headphones, is a technical problem that the industry urgently needs to solve. Utility Model Content
