    Abstract: This application provides an electroacoustic transducer and an electronic device, the electroacoustic transducer includes a central magnet, two side magnets, a lower electrode plate, a side electrode plate, a frame, a sound diaphragm, a voice coil, and two flexible circuit boards. The central magnet and the two side magnets are disposed on the lower electrode plate. The side electrode plate is disposed on a surface of the two side magnets which is opposite to the lower electrode plate. Two surfaces of the frame are respectively fixedly connected to the sound diaphragm and a surface of the side electrode plate which is opposite to the lower electrode plate. The voice coil is located inside the frame. The two flexible circuit boards are symmetrically distributed on a peripheral side of the voice coil, two ends of the flexible circuit board are respectively connected to the voice coil and the side electrode plate.

    Abstract: A first sound element is connected to a left sound-emitting hole and an upper sound-emitting hole. A second sound element is connected to a right sound-emitting hole and the upper sound-emitting hole. A third sound element is connected to a lower sound-emitting hole. When the terminal is in a portrait mode, a processor controls the first sound element and the second sound element to play sound channels on different sides and emit a sound from the left sound-emitting hole and the right sound-emitting hole. When the terminal is in a landscape mode, the processor controls the first sound element and/or the second sound element to play a sound channel on one side and emit a sound from at least one of the left sound-emitting hole, the right sound-emitting hole, and the upper sound-emitting hole, and the processor controls the third sound element to play a sound channel on another side.

    Abstract: This application provides a mobile terminal including a first magnet and a second magnet. At least a part of the first magnet and at least a part of the second magnet are disposed in the accommodating space. The first magnet is disposed on a back facet of the display module, the second magnet is disposed on the middle frame, and positions of the first magnet and the second magnet are disposed opposite to each other. The first magnet is a coil, and the second magnet is a main magnet; or the first magnet is a main magnet, and the second magnet is a coil. The main magnet is a Halbach array, and the main magnet generates a unilateral magnetic field on a side opposite to the coil.
