What other common wireless demonstration transmitters are there?

A wireless presentation transmitter is a device used to transmit audio, video, or other data wirelessly. Here are some common wireless demo transmitters:

Wireless Microphone: A wireless microphone is the most common form of wireless presentation transmitter and is used to transmit audio signals during a speech or performance. These devices typically use radio waves or infrared rays to transmit signals, allowing users to move freely within a certain range without being restricted by wires.

Wireless loudspeakers: Wireless loudspeakers are used to transmit audio signals in larger spaces, such as schools, churches, or public spaces. These devices usually include a receiver and multiple transmitters, with the receiver sending audio signals to each transmitter to achieve the amplification function.

Wireless Display: Wireless displays are used to transmit video signals. These devices typically use radio waves or infrared rays to transmit signals and allow users to move freely within a certain range without being restricted by wires.

Wireless Keyboard and Mouse: A wireless keyboard and mouse is another form of wireless presentation transmitter used for giving presentations or working on a computer. These devices typically use radio waves or Bluetooth to transmit signals and allow users to move freely within a certain range.

It should be noted that the performance and quality of wireless demonstration transmitters will vary depending on factors such as brand, model, and usage environment. When choosing a wireless presentation transmitter, consider factors such as its signal range, stability, battery life, and ease of use.
