Abstract: An audio signal processing method, includes acquiring a first distance between a current position and an initial position of a mobile device, and a second distance between the current position of the mobile device and a wearable device. Determining a first deflection angle according to the first distance, the second distance and the initial distance between the mobile device and the wearable device. Acquiring a second deflection angle of the wearable device reflecting a posture change. Determining relative position information between the mobile device and the wearable device according to the first deflection angle, the second deflection angle and the second distance and processing an audio signal based on the relative position information to obtain a playing audio played by the wearable device.

Abstract: An information transmission method, an information transmission apparatus, and a storage medium include encoding information to be transmitted to obtain an ultrasonic encoded signal; obtaining an ultrasonic transmission signal based on the ultrasonic encoded signal and an ultrasonic wake-up signal, the ultrasonic wake-up signal for waking up an ultrasonic receiver to decode the ultrasonic encoded signal; and transmitting the ultrasonic transmission signal to the ultrasonic receiver.
