The invention provides a loudspeaker. The loudspeaker comprises a basin stand with an accommodating space, a vibration system and a magnetic circuit system, the vibration system and the magnetic circuit system are arranged in the accommodating space, the magnetic circuit system comprises a magnetic frame fixed on the basin stand and a magnetic steel assembly arranged in the magnetic frame, the magnetic frame and the magnetic steel assembly are arranged at an interval to form a magnetic gap, and the magnetic frame is provided with an abdicating groove; a voice coil of the vibration system is arranged in a magnetic gap of the magnetic circuit system. A framework of the vibration system is arranged around the magnetic circuit system; the voice coil is suspended in the magnetic gap through thesecond support sheet passing through the abdicating groove. The framework comprises a plurality of first supporting pieces which are connected with the second supporting pieces and arranged at intervals. According to the loudspeaker, the lower voice diaphragm of the vibration system is arranged on the basin stand and the plurality of first supporting pieces, the loudspeaker further comprises theannular supporting pieces clamped between the first fixing parts and the first supporting pieces, and through the mode, the lower voice diaphragm is better supported, so that the bonding between the lower voice diaphragm and the framework is firmer.
Description
【Technical field】 [0001] The invention relates to the field of electroacoustic conversion, in particular to a loudspeaker. 【Background technique】 [0002] With the development of technology, more and more electronic devices have built-in sound generating devices. Generally, the speaker will provide a uniform magnetic field through the magnetic steel, so that the voice coil with the alternating current vibrates in the uniform magnetic field, and the voice coil drives the diaphragm to vibrate to make the speaker produce sound. [0003] Loudspeakers in the prior art generally bond the sound film to the frame and frame respectively, but during the process of speaker assembly and vibration and sound production, the sound film is prone to poor bonding with the frame and frame. This in turn affects the acoustic performance of the loudspeaker. [0004] Therefore, it is necessary to provide a new technical solution to improve the above problems. 【Content of invention】 [0005] T...
