Description

Priority is claimed to Chinese Patent Application No. 202211350598.8, filed with the China National Intellectual Property Administration on October 31, 2022 and entitled "CALL CONTROL METHOD, ELECTRONIC DEVICE, AND STORAGE MEDIUM". TECHNICAL FIELD This disclosure generally relates to the field of electronic technologies, and the invention in particular relates to a call control method. BACKGROUND Currently, for most mobile phones, sound production in voice communication of a mobile phone is implemented through a receiver arranged at the top of the mobile phone. Generally, a sound output hole needs to be correspondingly arranged on the mobile phone at a position of the receiver, to release energy generated during sound production of the receiver. The sound output hole is usually provided on a front panel of the mobile phone. With the development of large-screen and full-screen mobile phones, for some full-screen mobile phones, a sound output hole is designed into the form of a long slit, and is located at a joint between a middle frame of the mobile phone and a front panel of the mobile phone. In addition, to ensure that an external sound output area is large enough to have a good sound output effect, for some full-screen mobile phones, an opening is further added at the top of a middle frame as a sound output hole. However, when a user holds a mobile phone to perform on-ear listening (for example, in a voice call scenario), voice output through a receiver is emitted not only from a sound output hole at a side slit, and a large part of energy is emitted from a sound output hole at the top. Therefore, sounds emitted from the sound output holes not only can be heard by the user, but also can be heard by another user in a quiet environment. Consequently, sound leakage is caused, and user privacy leakage is prone to occur. The technical problem addressed in CN 114 466 097 A is the issue of sound leakage in mobile terminals (such as smartphones) during sound output, particularly as device designs move toward higher screen-to-body ratios. As the screen size increases and bezels shrink, the traditional sound output hole (earpiece) is forced closer to the edge or even onto a curved surface, making it less aligned with the user's ear during calls. This misalignment results in sound being leaked into the environment, reducing privacy and sound quality for the user. The document solves this problem by introducing a new mobile terminal structure and sound output method that includes a screen sound production component disposed on the back side of the screen (typically in the upper half), which can drive the screen to vibrate and produce sound. Multiple sound output modes, including a "privacy mode" where the screen sound production component is used to generate sound close to the user's ear, minimizing leakage. The system can automatically switch between modes (privacy, earpiece, play) based on environmental conditions, user proximity, ambient noise, and user actions, ensuring that sound is delivered in a way that maximizes privacy and sound quality while minimizing leakage. SUMMARY The invention is directed to the call control method of claim 1. Advantageous embodiments are set out in the dependent claims.
