Abstract
An information transmission method and an electronic device are provided. The information transmission method is applied to an ultrasonic wave transmitting device, and includes: transmitting a Bluetooth wake-up signal; obtaining an ultrasonic transmission signal based on information to be transmitted; and transmitting the ultrasonic transmission signal to an ultrasonic wave receiving device, wherein the Bluetooth wake-up signal is configured to wake up the ultrasonic wave receiving device to receive the ultrasonic transmission signal. In the ultrasonic wave receiving device, such elements as a decoder and an acoustic wave receiver may be in a normally-off state; and when it is needed to transmit information through an ultrasonic wave, the ultrasonic wave transmitting device first transmits the Bluetooth wake-up signal; and upon the reception of the Bluetooth wake-up signal, the ultrasonic wave receiving device wakes up related elements to receive the ultrasonic signal.
