A1

A method for sending a sound signal, a method for receiving a sound signal, and a method for detecting the relative position of devices, relating to the technical field of terminals. The methods are applied to a system. A first device comprises a first loudspeaker, a second loudspeaker, and a third loudspeaker; the first loudspeaker and the second loudspeaker are located on a first side of a first plane, the third loudspeaker is located on a second side of the first plane, the first loudspeaker and the third loudspeaker are located on a third side of a second plane, and the second loudspeaker is located on a fourth side of the second plane; and the first plane is not parallel to the second plane. The methods comprise: the first device sends a first sound signal by means of the first loudspeaker and the second loudspeaker, and sends a second sound signal by means of the third loudspeaker (S3201, S3401); the second device determines a first relative position of the second device and the first device according to a first time of arrival of the first sound signal and a second time of arrival of the second sound signal (S3403). The costs of detecting the relative position of devices are reduced.
