Problems solved by technology

[0002] Most of the TV channel selection methods currently on the market are infrared sensor channel selection methods. However, when the infrared rays encounter obstacles, the channel selection action cannot be completed. The user must point the infrared rays at the TV to change channels. The infrared sensor can only be used with a fixed device, such as a remote control, which cannot be used alone. Once the fixed device is damaged, the device must be replaced to continue to complete the channel change action, which increases the cost of use

Description

technical field [0001] The invention relates to a channel selection device, in particular to a voice-activated channel selection device, which belongs to the field of electronic technology. Background technique [0002] Most of the TV channel selection methods currently on the market are infrared sensor channel selection methods. However, when the infrared rays encounter obstacles, the channel selection action cannot be completed. The user must point the infrared rays at the TV to change channels. The infrared sensor can only be used with a fixed device, such as a remote control, and cannot be used alone. Once the fixed device is damaged, the device must be replaced to continue the channel-changing action, which increases the cost of use. Contents of the invention [0003] Aiming at the above-mentioned problems in the prior art, the present invention provides a voice-activated channel selection device, which can complete the channel-changing action through voice, has no ar...
