Bluetooth Transmitter

A Bluetooth transmitter is a device that sends audio signals wirelessly to Bluetooth-enabled receivers such as headphones, speakers, or car audio systems. It effectively converts audio from a source lacking native Bluetooth capability into a Bluetooth signal.

Material

Bluetooth transmitters are typically constructed using a combination of materials:

• Enclosure: Plastic (ABS, polycarbonate) is common for the outer casing, providing durability and lightweight construction. Metal alloys (aluminum) may be used for premium models offering improved heat dissipation and structural integrity.
• Circuitry: Printed Circuit Boards (PCBs) house the electronic components. These include a Bluetooth chip, audio codec chip (DAC/ADC), amplifier, antenna, and power management circuitry.
• Antenna: Often made of copper or a similar conductive material, sometimes integrated into the PCB or as a separate component.
• Connectors: Gold-plated connectors (3.5mm audio jack, USB) are used for audio input and power.
• Battery (if portable): Lithium-polymer batteries are common for rechargeable models, offering high energy density.

Purpose

The primary purpose of a Bluetooth transmitter is to add Bluetooth functionality to devices that do not inherently possess it. This enables wireless audio streaming without the need for physical cables.

Function

A Bluetooth transmitter functions by:

1. Audio Input: Receiving an analog or digital audio signal from a source (e.g., TV, MP3 player, PC).
2. Analog-to-Digital Conversion (if necessary): Converting the analog audio signal into a digital format.
3. Encoding: Encoding the digital audio signal using a Bluetooth audio codec (SBC, aptX, AAC, LDAC).
4. Transmission: Transmitting the encoded audio signal wirelessly via Bluetooth radio waves to paired receiving devices.
5. Pairing: Establishing a secure connection with Bluetooth receivers using a pairing process.

Usage Scenarios

• TVs: Connecting to TVs without built-in Bluetooth to stream audio to wireless headphones for private listening.
• MP3 Players/CD Players: Adding wireless capability to older audio players.
• Computers/Laptops: Enabling wireless audio streaming to headphones or speakers.
• Stereo Systems: Adding Bluetooth connectivity to existing stereo receivers or amplifiers.
• In-Flight Entertainment Systems: Connecting to airplane entertainment systems to use personal headphones.
• Gym Equipment: Streaming audio from compatible machines to wireless earbuds.

Common Types

• Standard Bluetooth Transmitters: Basic models supporting the SBC codec. Offer compatibility with most Bluetooth devices but may have limited audio quality.
• aptX Transmitters: Support the aptX codec, providing higher-quality audio streaming with lower latency. Suitable for watching videos and gaming.
• aptX LL (Low Latency) Transmitters: Specifically designed for low-latency audio transmission, minimizing audio delay for a synchronized viewing experience.
• AAC Transmitters: Support the AAC codec, commonly used by Apple devices. Offers good audio quality, especially with iOS devices.
• LDAC Transmitters: Support the LDAC codec, offering the highest audio quality available via Bluetooth. Requires compatible receiving devices.
• Dual-Device Transmitters: Capable of pairing with two Bluetooth devices simultaneously.
• USB Transmitters: Connect directly to a computer's USB port, providing power and audio input.
• 3.5mm Transmitters: Connect to audio outputs using a 3.5mm audio jack.
• Optical/Toslink Transmitters: Connect to digital audio outputs using an optical cable.

Key Specifications

• Bluetooth Version: (e.g., Bluetooth 5.0, Bluetooth 5.3) – Impacts range, speed, and efficiency.
• Audio Codecs Supported: (SBC, aptX, AAC, LDAC) – Determines audio quality.
• Range: Typically 10-30 feet (3-10 meters).
• Battery Life (if portable): Varies depending on usage and model.
• Latency: The delay between the audio source and the receiver. Lower latency is preferred for video.
• Frequency Response: The range of frequencies the transmitter can reproduce.

Based on the provided information, the following HS codes may be relevant to a bluetooth transmitter:

• 8517.69.00.00: This HS code covers telephone sets, including smartphones and other telephones for cellular networks or for other wireless networks; other apparatus for the transmission or reception of voice, images or other data, including apparatus for communication in a wired or wireless network (such as a local or wide area network), other than transmission or reception apparatus of heading 8443, 8525, 8527 or 8528; parts thereof: Other apparatus for transmission or reception of voice, images or other data, including apparatus for communication in a wired or wireless network (such as a local or wide area network): Other. This is a broad category encompassing various communication devices, and a bluetooth transmitter falls under the scope of “other apparatus for transmission or reception of voice, images or other data”.

  • Chapter 85: Electrical machines and apparatus; parts thereof.
  • Heading 8517: Telephone sets, etc.
