摘要： The present invention relates to a speaker having a frame, a magnetic circuit system and a vibrating system. The magnetic circuit system has a main magnet and an auxiliary magnet. The vibrating system has a vibrating diaphragm, a voice coil and a suspension with a first avoiding space. The auxiliary magnet is surrounding the main magnet and passed through the first avoiding space. The first avoiding space is positioned in the suspension so that the auxiliary magnet can be arranged around the main magnet, thereby enhancing the strength of the magnetic field of the magnetic circuit system, and ensuring uniform force on the vibrating diaphragm for improving BLX symmetry of the vibrating diaphragm.

摘要： A speaker includes a holder, a magnetic circuit unit, and a vibration unit including a diaphragm, a voice coil, and a centering support plate. The centering support plate is fixed to a side of the voice coil facing away from the diaphragm. One end of the centering support plate fixed to the voice coil is provided with a pad electrically connected to the voice coil. The diaphragm includes a central portion, a suspension portion surrounding the central portion, and a dome fixed to the central portion. The dome includes a body attached to the central portion, and a connection portion extending from an edge of the body towards the pad and fixedly connected to the pad. With the connection portion, the pad of the centering support plate can be fixed, preventing the tone quality of the speaker from being damaged by the pad, and t reducing noise.

摘要： The invention provides a terminal device having a main body, a sounding assembly and a cover plate. The sounding assembly includes a housing and a sounding body. The housing has an accommodating groove and a first sounding channel. The main body has a second sounding channel and a first sound emitting hole. The cover plate has a first through hole. When the sounding assembly is located at the first position, the sound is propagated to the outside through the first through hole, the second sounding channel and the first sound emitting hole in sequence. When the sounding assembly is located at the second position, the sound is propagated to the outside through the first sounding channel. The present invention improves the problem that the sound effect is affected by airflow sound, piano sound, etc., generated by the terminal device in the speaker mode.
