Abstract

The invention relates to the field of loudspeakers, and provides a loudspeaker with a positioning piece and an assembling method of the loudspeaker. The assembling method of the loudspeaker with the positioning piece comprises the following steps: S1, adhering a dome with a second through hole and a third through hole to the outer side of a vibrating part of a vibrating diaphragm with a first through hole; s2, putting the vibrating diaphragm bonded with the dome into an injection mold, and putting a voice coil into the injection mold; s3, starting an injection molding procedure, premeating injection molding molten liquid into the first through hole, the second through hole and the third through hole, bonding the voice coil, the vibrating diaphragm and the dome into a whole, and forming a solid positioning piece after the injection molding molten liquid is cooled; and S4, bonding a base frame bonded with the magnetic circuit system on the vibrating diaphragm, and completing assembly. According to the loudspeaker, the positioning piece is arranged between the vibrating diaphragm and the voice coil, the voice coil, the vibrating diaphragm and the dome are fixed into a whole by the positioning piece, and the insertion depth of the voice coil in the magnetic field is increased, so that the effective height of the voice coil for cutting the magnetic field is increased, and the electroacoustic performance of the loudspeaker is improved.

Description

technical field [0001] The invention relates to the field of loudspeakers, more specifically, to a loudspeaker with a positioning part and an assembly method thereof. Background technique [0002] The loudspeaker is a transducer device that converts electrical signals into acoustic signals, and the performance of the loudspeaker has a great influence on the sound quality. The loudspeaker is the weakest part in the audio equipment, but it is the most important part for the sound effect. There are many types of speakers, and their prices vary widely. Audio electric energy, through electromagnetic, piezoelectric or electrostatic effects, causes its diaphragm to vibrate and resonate (resonate) with the surrounding air to produce sound. [0003] At present, due to the low effective height of the cutting magnetic field of the voice coil in the existing speakers on the market, the electro-acoustic performance of the speakers is poor. Contents of the invention [0004] The inve...
