    摘要: A system for providing magnetic field audio signals to a receiver in an aquatic environment. The system includes an audio source configured to provide an electronic audio signal, and an induction loop amplifier configured to receive the electronic audio signal and convert the received electronic audio signal into a current. The system further includes a wire loop connected with the induction loop amplifier, the wire loop bounding at least part of the aquatic environment and around the receiver in the aquatic environment, the wire loop producing a magnetic field from the current to generate an audio frequency induction loop to transmit the electronic audio signal to the receiver in the aquatic environment.

    摘要: The present disclosure provides an underwater speaker. The underwater speaker includes an outer shell, with a circuit board arranged inside, a speaker, and a lampshade with a first opening at the top. The speaker is electrically connected to the circuit board. The luminescent body is arranged on the circuit board. The luminescent body is oriented towards the interior of the lampshade, and a graphic mapping unit is formed on the lampshade. This embodiment uses the speaker to play audio and achieve the function of an underwater speaker. When the luminescent body emits light, the light can be mapped onto the water. This improves the multiplicity and effect of light and shadow, and meets users' needs for complex and multi-element light and shadow effects.
