Description

Technical Field

[0001] The utility model relates to the field of loudspeaker equipment, in particular to a loudspeaker paper cone that is easy to dissipate heat. Background Art

[0002] The speaker cone is an important conversion device that converts electrical signals into sound signals. When audio current passes through the speaker's voice coil, the voice coil will move due to the force in the magnetic field. The cone is closely connected to the voice coil, and the movement of the voice coil will drive the cone to vibrate. The vibration of the cone will cause the surrounding air to vibrate, thereby generating sound waves, realizing the conversion from electrical signals to sound signals.

[0003] In the current loudspeaker field, many existing loudspeaker cones have unsatisfactory heat dissipation effects. When the loudspeaker operates for a long time or is in a high-power output state, a large amount of heat will accumulate on the cone. Due to poor heat dissipation, excessively high temperatures can cause changes in the physical and chemical properties of the cone material. For example, the cone may crack or deform, which will seriously affect the sound transmission quality, making the speaker's frequency response unstable and the sound distortion increased. At the same time, existing loudspeakers often have the defect of being inconvenient to disassemble, which brings many troubles during repair and maintenance. When a loudspeaker fails and needs to be repaired, the complicated and time-consuming disassembly process will increase the difficulty and cost of repair. For this reason, we propose a loudspeaker cone that is easy to dissipate heat. Utility Model Content
