Abstract

The invention disclose a method for fabricating a loudspeaker. The method comprises the following steps of preparing a support frame; preparing a vibrating membrane, wherein a globe-roof convex part is arranged at the center of the vibrating membrane; preparing a round-dish voice coil; pasting the voice coil on the bottom end of the vibrating membrane, thereby assembling the voice coil and the vibrating membrane into a vibrating assembly; arranging the vibrating assembly on the support frame; preparing a radial magnet; arranging the radial magnet above the support frame and below the vibrating assembly; preparing a PCB (printed circuit board); arranging the PCB on the support frame and allowing the PCB to electrically connect the vibrating assembly. The fabricating method is characterized in that the voice coil is in a round-dish structure, and the total height from the voice coil to the loudspeaker reaches below 4.2mm when the voice coil is pasted on the bottom end of the vibrating membrane, so that the loudspeaker is thinned and miniaturized; meanwhile one round-dish voice coil is superimposed on the vibrating membrane, so that the deformation of the vibrating membrane can be greatly reduced in a vibrating process, and the uneven frequency response curve caused by segmentation and vibration can be solved.

Description

technical field

[0001] The invention relates to the technical field of electroacoustic transducer elements, in particular to a manufacturing method of a loudspeaker. Background technique

[0002] In the field of modern acoustic and electric technology, the loudspeaker, also known as the horn, is an important transducer device, which is commonly found in various communication equipment, audio-visual equipment and other electronic devices. A uniform magnetic field is formed inside the speaker, and the voice coil made of conductive material is suspended in the uniform magnetic field of the speaker. Due to the action of the Loren magnetic force, when the signal carrying the sound characteristics in the voice coil changes, the voice coil will vibrate, which will drive the diaphragm to emit sound, and realize the conversion of electrical signals into sound.

[0003] At present, the dynamic speaker is mainly composed of a support frame 20', a vibration assembly 10' disposed on the...
