Abstract
The utility model discloses a vibrating diaphragm for a loudspeaker, which comprises two end portions and a diaphragm body, wherein the diaphragm body is positioned between the two end portions and includes a front side and a back side. The internal diameter of one end portion is greater than that of the other end portion, cross section of the diaphragm body is annular, and the diaphragm body comprises a main body whose sectional top is conical. The vibrating diaphragm is characterized in that the diaphragm body is equipped with at least one rough portion. A processing method of the vibrating diaphragm comprises the steps including beating, pulp dredging, hot pressing and punching, wherein in the hot pressing process, the rough portions are dried freely. A processing device of the vibrating diaphragm comprises an upper die and a lower die, wherein a lower pressure mold surface is formed in the upper of the lower die, an upper pressure mold surface corresponding with the lower pressure mold surface is formed in the lower of the upper die, and either the upper pressure mold surface or the lower pressure mold surface is equipped with a pressure loosening boss. The utility model also discloses the loudspeaker consisting of the vibrating diaphragm.
Description
Technical field
The utility model relates to loud speaker, also relates to the vibrating diaphragm on the loud speaker especially, also relates to 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, former sound distortion then, auditory effect is bad.
The utility model content
The purpose of this utility model provides a kind of vibrating diaphragm for loud speaker, comprise two ends, the film body with front and back between two ends, 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 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 top die face corresponding with pressing down die face formed at the bottom of described patrix, 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 utility model compared with prior art has following advantage: cut apart vibration when being conducive to reduce the work of loud speaker, reduce the peak valley point of medium-high frequency section.
