Problems solved by technology
The vibration diaphragm on the existing loudspeaker is generally in the shape of a truncated cone. When the conical inclined part on the diaphragm vibrates and makes sound, there will be a peak in the middle and high frequency bands on the frequency response curve, such as the frequency band of 2000Hz~3000Hz, which is easy to cause Harsh or hoarse sound, the original sound is distorted and the hearing effect is not good

The invention discloses a vibrating diaphragm for a loudspeaker. The vibrating diaphragm comprises two end portions and a diaphragm body located between the two end portions, the diaphragm body is provided with a front face and a back face, an internal diameter of one end portion is larger than that of the other end portion, a cross section of the diaphragm body is ring-shaped, and the diaphragm body comprises a cutting-top cone-shaped main body. The vibrating diaphragm is characterized in that at least one rough portion is arranged on the diaphragm body. A manufacturing method of the vibrating diaphragm comprises the following steps of pulping, salving, conducting hot pressing, conducting free drying on the rough portion in a hot-pressing process and punching. A manufacturing device of the vibrating diaphragm comprises an upper die and a lower die, a lower pressing die face is formed on the upper portion of the lower die, an upper pressing die face corresponding to the lower pressing die face is formed on the lower portion of the upper die, and a releasing boss is arranged on the upper pressing die face or the lower pressing die face. The invention further comprises the loudspeaker of the vibrating diaphragm.
Description
technical field [0001] The invention relates to a loudspeaker, in particular to a vibrating diaphragm on the loudspeaker, and also to a processing method for the vibrating diaphragm and a processing device for the vibrating diaphragm. Background technique [0002] The loudspeaker belongs to the electro-acoustic transducer device. The diaphragm vibrates by electric energy through the electromagnetic effect. The vibrating diaphragm resonates with the surrounding air to produce sound, and the shape of the diaphragm will affect the sound effect. The vibration diaphragm on the existing loudspeaker is generally in the shape of a truncated cone. When the conical inclined part of the diaphragm vibrates and produces sound, there will be a peak in the middle and high frequency bands on the frequency response curve, such as the frequency band of 2000Hz~3000Hz, which is easy to cause If harsh or hoarse sound appears, the original sound will be distorted and the auditory effect will be b...
