Document Type and Number:
WIPO Patent Application WO/2023/134306
Kind Code:
A1
Abstract:
The present application provides a foldable electronic device, the electronic device comprising a housing, a first speaker and a second speaker. The housing comprises a first housing, a second housing and a rotating shaft, the first housing and the second housing being connected to two opposite sides of the rotating shaft, respectively, and the first housing and the second housing being rotatable relative to the rotating shaft, so as to switch between a folded state and an unfolded state. The first speaker and the second speaker may be driven to emit sound having the same vibration amplitude and opposite phases, thereby forming a dipole sound source. In the foldable electronic device in the embodiments of the invention, the two speakers are controlled to emit sound having the same vibration amplitude and opposite phases by means of independent sound outlet channels, thereby forming a dipole sound source. An anti-phase sound field superposition occurs at a far field of the electronic device to reduce sound loudness and definition, so that other people at the far field of the electronic device cannot hear the call sound, thereby achieving call privacy.
