Description

Technical Field

[0001] This utility model relates to the field of loudspeaker technology, and in particular to an irregularly shaped sound-generating unit, loudspeaker and device. Background Technology

[0002] The voice coil and diaphragm are important components of a loudspeaker's sound-producing unit. When current passes through the voice coil, an electromagnetic field is generated. This electromagnetic field interacts with the magnet, causing the diaphragm to vibrate, thereby producing sound. For example, a diaphragm and a loudspeaker with such a diaphragm are disclosed in patent number CN219999585U. The connection between the diaphragm and the voice coil is a planar connection structure. This planar connection mode results in limited connection strength, limited electrical signal reproduction, and a tendency to distortion. Utility Model Content

[0003] This invention aims to overcome the shortcomings of existing technologies by providing an irregularly shaped sound unit, loudspeaker, and device that offers stable connection and reduced distortion.

[0004] The present invention solves the technical problem by adopting the following technical solution: an irregularly shaped sound-generating unit, comprising a voice coil and a diaphragm connected together, characterized in that the connection between the voice coil and the diaphragm has a plurality of protruding connecting bodies I, and the connection between the diaphragm and the voice coil has connecting bodies II corresponding to the shape of the connecting bodies I, wherein the connecting bodies I and the connecting bodies II are mortise and tenon structures.

[0005] In several embodiments, the connector and the voice coil are made of different materials.

[0006] In several embodiments, the connector has a different thickness from the voice coil.

[0007] In several embodiments, the first connector and the second connector are both triangular, square, or trapezoidal.

[0008] In several embodiments, the cone is one of a planar solid, an arc-shaped solid, or a conical solid shape.

[0009] In several embodiments, the cone size is greater than or equal to the voice coil size.

[0010] In several embodiments, the voice coil has a cross-section that is either square or rectangular.

[0011] In several embodiments, the voice coil has a cross-section that is either circular or elliptical.

[0012] And a loudspeaker having the aforementioned irregularly shaped sound-emitting unit.

[0013] And, a device having the aforementioned speaker.

[0014] This utility model has the following beneficial effects:

[0015] This invention utilizes a three-dimensional mortise and tenon connection pattern, where the voice coil and diaphragm interlock and reinforce each other, making the voice coil more stable under high-frequency vibration, reducing distortion, and better reproducing electrical signals.

[0016] This invention strengthens the cone by using a toothed voice coil structure, thereby reducing cone break vibration, reducing distortion, and improving distortion performance.

[0017] This invention significantly increases the bonding surface between the voice coil and the diaphragm through a toothed voice coil structure, making the force transmission from the voice coil to the diaphragm more stable and suppressing transient distortion of the loudspeaker. When playing music, the sound is more natural and transparent, with excellent realism, and can delicately show the timbre characteristics of instruments and subtle changes in performance.
