Abstract

The embodiment of the invention provides an electromagnetic loudspeaker and a mobile terminal. The electromagnetic loudspeaker comprises a bracket (1), a diaphragm (2), a coil (3), a magnetic bowl (4), a magnet (5) and two vibration balance diaphragms (8). The magnet (5) is arranged in the groove (6) of the magnetic bowl (4). A gap (7) is formed between the magnet (5) and the sidewall of the magnetic bowl (4). The coil (3) is arranged on one side of the diaphragm (2) that faces the magnetic bowl (4) and extends into the gap (7) through the diaphragm (2). The vibration balance diaphragms (8) are arranged on the magnet (5) or the coil (3). Each vibration balance diaphragm (8) comprises a connecting part (9) and an empennage (10). The two vibration balance diaphragms (8) are oppositely arranged, and the spacing between the two empennages (10) is gradually increased along the direction away from the magnet (5) or the coil (3). According to the embodiments of the invention, the left traction force and the right traction force of the coil can be increased. Therefore, the coil is ensured to move in a preset direction. Meanwhile, the abnormal sound is reduced, and the tone quality is improved.

Description

technical field [0001] The invention relates to the technical field of mobile communication, in particular to an electromagnetic speaker and a mobile terminal. Background technique [0002] With the advent of the mobile Internet era, the number of mobile terminals continues to rise. Among the many mobile terminals, the mobile phone is undoubtedly the most common and portable terminal. At present, the functions of the mobile phone are extremely diverse, one of which is the high-quality music function, and the loudspeaker in the mobile phone is one of the necessary conditions for realizing the high-quality music function. At present, mobile phones on the market generally use electromagnetic speakers to realize the music playback function. [0003] Traditional electromagnetic speakers usually include coils, diaphragms (vibration systems), magnets, magnetic plates, magnetic bowls, brackets, protective covers, etc. Among them, the magnets, magnetic plates, and magnetic bowls fo...
