Abstract
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
The present invention relates to loud speaker, also relate to the vibrating diaphragm on the loud speaker especially, also relate to the processing method of vibrating diaphragm and the processing unit (plant) of vibrating diaphragm.
Background technology
Loud speaker belongs to electro-acoustic transducer device, makes diaphragm vibrate by electric energy by galvanomagnetic effect, and the diaphragm of vibration and ambient air resonate and sound, and the shape of diaphragm will influence sound effect.Vibrating diaphragm on the existing loud speaker is shape in the form of a truncated cone generally, taper rake on the diaphragm is when vibration sounding, medium-high frequency section on the frequency response curve, as 2000Hz ~ 3000Hz frequency range, spike can appear, cause the appearance of ear-piercing or hoarse sound easily, then former sound distortion, auditory effect is bad.
Summary of the invention
The purpose of this invention is to provide a kind of vibrating diaphragm that is used for loud speaker, comprise two ends, the film body between two ends with front and back, the internal diameter of one of them end is greater than the internal diameter of another end, the cross section of film body in the form of a ring, described film body comprises the main body that is frustroconical, and described film body is provided with the roughness of at least one.
Preferably, described roughness is arranged on the front of film body.
Preferably, described roughness is arranged on the back side of film body.
Preferably, described roughness has a plurality of, and a plurality of projectioies circumferentially distribute at intervals along film body.
Preferably, the formation that described roughness is paired, paired roughness is symmetrical distribution about the central shaft of film body.
A kind of processing method of vibrating diaphragm is characterized in that, it may further comprise the steps: making beating; Drag for slurry; Hot pressing allows roughness free dry in hot pressing; Die-cut.
A kind of processing unit (plant) of vibrating diaphragm, it is characterized in that: it comprises upper die and lower die, the top of described counterdie forms and presses down die face, and the bottom of described patrix forms and presses down the corresponding top die face of die face, described top die face or press down one of die face and be provided with loose belling platform.
A kind of loud speaker of involving vibrations diaphragm.
Because the utilization of technique scheme, the present invention compared with prior art has following advantage: cut apart vibration when helping reducing the work of loud speaker, reduce the peak valley point of medium-high frequency section.
