Bluetooth Voice Remote Control

With the rise of smart homes, Bluetooth voice remote controls are rapidly replacing traditional infrared remotes, becoming the preferred control tool for smart TVs and set-top boxes due to their convenient operation and intelligent interaction.

Unlike infrared remotes requiring line-of-sight, Bluetooth voice remotes leverage Bluetooth Low Energy (BLE) for non-directional, wide-ranging control. They support voice commands to simplify complex operations and enable smooth interaction through bidirectional communication, offering unparalleled convenience.

01 Working Principle

The core of Bluetooth voice remotes lies in their flexible control and efficient data transmission.

• Hardware Components: Include Bluetooth interface (signal transmission), Bluetooth control module (establishes communication channel), voice processing module (handles voice input/output), and human-machine interaction module (processes button commands).

• Voice Processing: User voice is captured via microphone, converted analog-to-digital, and sent via Bluetooth to the terminal (e.g., TV or set-top box) for command execution.

• Bidirectional Communication: Supports terminal responses and status feedback, like menu synchronization, enhancing interaction flexibility.

• Pairing Process: Requires initial pairing with the device, after which voice and button data can be transmitted.

  
  

02 Market Applications

Bluetooth voice remotes show strong market potential in smart homes, widely used in smart TVs and set-top boxes from brands like Xiaomi, TCL, and Skyworth. For example, Xiaomi’s Mi Bluetooth Voice Remote, powered by high-performance Bluetooth SoCs like the HS6621CxC, enhances user efficiency with precise voice search and smooth button control, becoming a standard accessory for smart TV users.

Voice interaction, simplifying content search and text input, is popular among young users and smart home enthusiasts. Dual-mode remotes also cater to traditional device users, demonstrating high market adaptability.

03 Recommended Chips

Selecting the right Bluetooth chip is critical for developing high-performance voice remotes. HS6621CxC and OM6621 series are ideal choices due to their high integration and low power consumption.
