[0002] A loudspeaker is an electroacoustic transducer that converts electrical signals into acoustic signals. It generates sound waves by driving a magnetic field through electric current, causing the voice coil and cone to vibrate. The design of a loudspeaker includes components such as the voice coil, magnet system, cone, and dust cap. Each component plays a key role and works together to produce sound. When installing the various components of the loudspeaker, you need to use a dispensing device to apply glue first, and then install the components.

[0003] According to the publication number CN221733913U, a dispensing machine for bonding a sound membrane dome includes a dispensing mechanism, and a stirring mechanism is fixedly installed inside the dispensing mechanism. In this prior art, two servo motors are started, and because the outer walls of the two rotating shafts are movably inserted inside the dispensing machine body, the two rotating shafts drive the two driving gears to rotate, and then drive the two racks to move relative to each other. Because the bottoms of the two racks are fixedly connected to the tops of the two sliders, the two racks drive the two sliders to move relative to each other, and then drive the two push plates to move relative to each other. Under the action of the two push plates and the limit plates, the two push plates have a limiting and fixing effect on the sound membrane dome that needs to be glued, avoiding the situation where the glue is unevenly coated due to position offset during the dispensing process, improving the dispensing quality, and further improving the use effect of the dispensing machine.
