Description

Technical Field

[0001] This utility model belongs to the field of loudspeakers, and specifically relates to a loudspeaker. Background Technology

[0002] A loudspeaker is a transducer that converts electrical signals into sound signals, and its performance greatly affects sound quality. The loudspeaker is the weakest component in an audio system, yet it is also one of the most crucial parts for achieving optimal sound effects. Existing miniature cavity alarm loudspeakers generally employ a circular cavity with a front-emitting sound structure. However, ultra-thin loudspeakers produce a relatively shrill sound when broadcasting announcements, and continuous broadcasting can lead to ear fatigue. Utility Model Content

[0003] This invention provides a loudspeaker to solve the above-mentioned technical problems.

The washer is disposed within the U-shaped iron cup. The washer is disposed on top of the magnet. The bottom of the voice coil is disposed within the U-shaped iron cup. The bottom of the voice coil is disposed outside the top of the magnet. The bottom of the voice coil is sleeved outside the washer. The composite diaphragm is disposed on top of the voice coil. The side sound-producing enclosure is disposed on one side of the top of the irregularly shaped housing.

[0007] Preferably, the sound-producing groove has two top groove walls; the two top groove walls intersect at an upward angle; and the side sound-producing cavity is disposed on one of the top groove walls.

[0008] Preferably, an echo block is provided at the intersection of the two top groove walls; the bottom wall of the echo block faces the top of the composite diaphragm parallel to the surface.

[0009] Preferably, the inner bottom of the sound-producing chamber is provided with a positioning groove; the sound-producing device also includes a frame; the frame is mounted on the positioning groove; a mounting groove is provided in the middle of the bottom of the frame; the U-shaped iron cup is installed in the mounting groove; a fitting groove is provided at the top of the frame; a fitting ring block is provided on the outer side of the composite diaphragm; the fitting ring block is fitted and installed in the fitting groove.

[0010] Preferably, a mounting ring is provided in the middle of the basin frame; the mounting groove is provided at the bottom of the mounting ring; and a reinforcing frame is provided between the mounting ring and the basin frame.

[0012] The beneficial effects of this utility model are as follows: The diaphragm in the internal sound-emitting device of this application is a composite diaphragm, so the sound source is not sharp. The outer shell is an irregularly shaped shell, and the internal cavity is also irregularly shaped, so the sound will not be muffled after passing through. Finally, the sound output part adopts a side sound-emitting structure on one side of the irregularly shaped shell. The sound is finally output through the side sound-emitting cavity and sound hole of the side sound-emitting structure, so the sound is clear and soft, which solves the problem of easy ear fatigue.
