We often see tour guides use wireless headsets when leading tours. A tour group consists of one person and multiple people. The tour guide only needs to use an interpreter to easily explain. As long as the tourists are paired with the tour guide interpreter, they can listen to the tour guide’s explanation at the same time by wearing wireless headsets. In addition, we also see some conferences using wireless headsets as simultaneous interpretation.
RFID technology has been widely used in daily life. Tour groups are one of them. The receiving and sending principles of RFID technology are applied to the scene where the tour guide explains and the team members listen. The tour guide explains through the wireless transmitter of the interpreter, the Bluetooth chip records the original sound, and then sends it out through the data signal. When the headset and the interpreter are paired with the same channel, the data module in the wireless headset receives the signal, translates the signal into analog audio and plays it out, so that the team members can listen to the explanation content at the same time.
The wireless tour guide system adopts DSP technology, with clear and natural sound and good modulation and adaptive sound effect. The wireless tour guide system transmission and reception have point-to-multipoint pairing encryption function, which can effectively eliminate external interference. It has up to 100 built-in ID pairing codes and supports single-speaker/multi-speaker mode on the same frequency. For more stable data transmission, the JL chip JL7016/JL7018F is recommended. Through self-developed private transmission protocols and algorithms, the entire solution has been strengthened and improved.
In addition to wireless lecture headphones, the JL7016C chip from JL is also suitable for high-end Bluetooth speakers, Douyin liker motherboards, wireless receiving and transmitting solutions. Bluetooth version 5.3, QFN32 package, one-to-many connection, a cost-effective Bluetooth chip. Features of this chip: intelligent anti-howling, delay as low as 40ms, SNR>104dB, noise floor as low as 4.5uVrms, equipped with JL second-generation sound algorithm.
One-to-many wireless tour guide headsets have multiple usage scenarios, such as tourist groups, government and enterprise reception, conference training, museums, etc.
