Referring to fig. 4, in the present embodiment, an angle a1 between the direction X1 of the first sound outlet 101 and the direction perpendicular to the first surface 110 (the direction of the arrow Z1 in fig. 4) is less than 45 degrees, wherein the first sound outlet 101 may be disposed on the first surface 110 or at an angle between the first surface 110 and the side surface 130 (the top side surface) (shown in fig. 4). The sound output from the first sound output hole 101 is mainly used for an application scene with high privacy requirements, such as a call, which requires a small sound.
Optionally, the second sound outlet hole 102 in this embodiment is disposed on the side (generally, the top side) 130, and the orientation of the second sound outlet hole 102 is not particularly limited. The sound output from the second sound outlet 102 has two application scenarios. In a privacy scene, the sound of the second sound outlet 102 is matched with the sound of the first sound outlet 101 to generate sounds with the same vibration amplitude and opposite phases, so that a dipole sound source is formed, an anti-phase sound field superposition is generated at a far field of the electronic equipment, the loudness and the definition of the sound are reduced, other people at the far field of the electronic equipment cannot hear conversation sound, and the privacy of the conversation is realized. In an application scene of an external power amplifier, the sound of the second sound outlet 102 and the sound of the first sound outlet 101 generate sound with the same phase, so that the same-phase sound field superposition is formed, the sound loudness is enhanced, and the external playing effect of the electronic equipment is improved.
