Abstract
In an embodiment an acoustic transmission system includes a primary side having a transmitting unit configured to provide a transmit signal, a receiving unit configured to receive a received signal in response to the transmitted signal and an electroacoustic transducer configured to convert the transmit signal into an acoustic signal and an acoustic signal into the receive signal and a secondary side having a transponder configured to receive a receive signal and transmit a transmit signal and an electroacoustic transducer located between the primary side and the secondary side, the electroacoustic transducer having a medium permeable to acoustic signals.

An acoustic transmission system comprising:
- a primary side comprising:
- a transmitting unit configured to provide a transmit signal;
- a receiving unit configured to receive a receive signal in response to a transmitted signal;
- and
- an electroacoustic transducer configured to convert the transmit signal into an acoustic signal and an acoustic signal into the receive signal;
- and
- a secondary side comprising:
- a transponder configured to receive a receive signal and transmit a transmit signal;
- and
- an electroacoustic transducer;
- and
- a medium permeable to acoustic signals between the primary side and the secondary side,
- wherein elements of the secondary side are operable by energy transmitted from the primary side,
- wherein the primary side is configured to communicate with more than one secondary sides at the same time by using an anti-collision method
- to avoid an overlap of acoustic signals of different secondary side.
A method for communicating a signal between a primary side and at least two secondary sides, the method comprising:
- transmitting, by a transmitting unit of the primary side, a carrier signal to a receiving unit of each of the secondary sides;
