Description

This application claims priority to Chinese Patent Application No. 202311270413.7, filed with the China National Intellectual Property Administration on September 27, 2023 and entitled "UNDERWATER COMMUNICATION METHOD AND SYSTEM, AND RELATED APPARATUS", which is incorporated herein by reference in its entirety. TECHNICAL FIELD This application relates to the communication field, and in particular, to an underwater communication method and system, and a related apparatus. BACKGROUND With continuous development of communication technologies, more electronic devices support underwater communication, which provides great convenience for users who need to perform underwater operations or have underwater sports hobbies such as diving. When an electronic device worn by the user is in an underwater state, the user may use the electronic device to communicate with another electronic device in a conventional wireless communication manner such as Bluetooth or radio frequency. However, in water, radio signals attenuate severely, and long-distance underwater communication cannot be implemented. SUMMARY This application provides an underwater communication method and system, and a related apparatus, to implement underwater communication between a plurality of electronic devices. In addition, attenuation of an acoustic wave signal is lower than that of a conventional radio signal in water, and therefore, an underwater communication distance can be increased by using the acoustic wave signal. According to a first aspect, this application provides an underwater communication method, applied to a first electronic device. The method includes: receiving a first operation of a user, and in response to the first operation, setting an identity of the first electronic device to a first identity; when the first electronic device is underwater, receiving a second operation of the user, and in response to the second operation, displaying one or more messages, where the one or more messages include a first message; and receiving a third operation of choosing, by the user, to send the first message, and in response to the third operation, sending a first acoustic wave signal, where the first acoustic wave signal carries the first message and the first identity. In this way, underwater communication using acoustic wave signals has a longer propagation distance than a conventional wireless communication manner. In addition, sent information carries an identity, used to notify a receiver of a sender of the information. In addition, the identity may be an identity set by the user, and the user may also change the identity in different application scenarios. For example, an identity of the user on a first date is a coach, and an identity of the user on a second date is a dive buddy. The user may set the identity to the coach on the first date, and may further change the identity to the dive buddy on the second date. In this way, the user may change, based on an identity change of the user, an identity set in the electronic device, so that a user of the receiver quickly determines the sender of the information based on the identity in the information. In a possible implementation, before the second operation is received, the method further includes: The first electronic device detects that the first electronic device is underwater. In a possible implementation, the first operation is an operation of selecting the first identity by the user; and the method further includes: displaying an identity list before receiving the first operation, where the identity list includes a plurality of identities, and the plurality of identities include the first identity. In this way, the plurality of optional identities can be provided for the user, to facilitate user operations and reduce operation time. In a possible implementation, the first operation is an operation of inputting the first identity by the user. In this way, the user may also enter the identity. In a possible implementation, the first electronic device further includes a first button, and the second operation is an operation performed by the user on the first button. In this way, underwater, the first electronic device may be triggered via a button (including a crown and the like) to display one or more messages. In a possible implementation, the first electronic device further includes a second button and a third button; and receiving the third operation of choosing, by the user, to send the first message, and in response to the third operation, sending the first acoustic wave signal specifically includes: receiving an operation performed by the user on the second button, and in response to the operation performed by the user on the second button, displaying a selection indicator on the first message, where the selection indicator indicates to the user that the first message is selected; and receiving an operation performed by the user on the third button, and in response to the operatio
