Abstract
The invention discloses a vibrating diaphragm of a loudspeaker and the loudspeaker comprising the vibrating diaphragm. A cone-shaped inclination part of the vibrating diaphragm of the loudspeaker is provided with a through hole, a waterproof sheet covers the through hole, and therefore peaks of mid-high frequency bands in a frequency response curve of the loudspeaker can be reduced, so that the frequency response curve of the mid-high frequency bands is more smooth, the sound effect is improved, and original sound can be reflected more truly.
Description
Technical field
the present invention relates to loundspeaker diaphragm, also relate to the loud speaker that comprises this vibrating diaphragm.
?
Background technology
loud speaker belongs to electro-acoustic transducer device, and electric energy makes diaphragm vibrate through galvanomagnetic effect, and the diaphragm of vibration and ambient air resonate and sound; The structure of diaphragm will influence sound effect, and existing vibrating diaphragm is shape in the form of a truncated cone, like this on the diaphragm conical inclination portion when vibration sounding; Medium-high frequency section on the frequency response curve; Like 1000Hz ~ 10000Hz 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
First purpose of the present invention provides to be offered perforation and in perforation, is covering the loundspeaker diaphragm that flashing reduces medium-high frequency section spike in the conical inclination portion;
second purpose of the present invention provides the loud speaker that comprises above-mentioned loundspeaker diaphragm, and this loud speaker smoothly improves auditory effect through frequency response curve medium-high frequency section.
for achieving the above object, the technical scheme that the present invention adopts is: a kind of loundspeaker diaphragm, have conical inclination portion, and offer perforation in the said conical inclination portion, be coated with flashing in the said perforation.
preferably, said perforation has a plurality of, and a plurality of said perforation distribute along the circumferential direction of said conical inclination portion separately, all are coated with said flashing in each said perforation.
further preferably, said perforation has at least a pair of, and paired said perforation is symmetrical distribution according to the center line of said conical inclination portion.
preferably, said flashing covers the front of said perforation.
comprise the loud speaker of above-mentioned loundspeaker diaphragm.
preferably; This loud speaker comprise intermediate recess form the framework of resonant cavity, be arranged in said resonant cavity vibrating diaphragm, be fixed on fixedly magnetic circuit component on the said framework, can be driven the voice coil loudspeaker voice coil that do axial motion by said fixedly magnetic circuit component; The outer peripheral face of said voice coil loudspeaker voice coil is connected on the inner peripheral surface of said framework through the location elastic wave sheet; The periphery of said vibrating diaphragm is bonded on the outer peripheral face of said voice coil loudspeaker voice coil, and the neighboring of said vibrating diaphragm is bonded in the inner rim portion of said framework through elastic edge.
are because the utilization of technique scheme; The present invention compared with prior art has advantage: in the conical inclination portion of loundspeaker diaphragm, offer perforation; Cover flashing in the perforation, can reduce the spike of the medium-high frequency section of loud speaker frequency response curve like this, make that the frequency response curve of medium-high frequency section is comparatively level and smooth; Improve sound effect, more can reflect primary sound truly.

Embodiment
Structure of the present invention is further set forth below in conjunction with accompanying drawing in
.
are in Fig. 1-3; A kind of loundspeaker diaphragm has conical inclination portion 1, offers perforation 2 in this conical inclination portion 1; Be coated with flashing 3 in the perforation 2; In Fig. 3, flashing 3 covers the front of perforation 2, and the front here refers to the surface that vibrating diaphragm caves in into.The number of perforation 2 can be for one or more; When being a plurality of, a plurality of perforation 2 distribute along the circumferential direction of conical inclination portion 1 separately, in the present embodiment at perforation 2 number; Perforation 2 has at least a pair of; Paired perforation 2 is symmetrical distribution according to the center line of conical inclination portion 1, all is coated with flashing 3 in each perforation 2, and is as shown in Figure 1.
The vibrating diaphragm that
will offer paired perforation 2 and in perforation 2, cover flashing 3 is assembled in the loud speaker and uses; Shown in Figure 4 and 5; Loud speaker comprise intermediate recess form the framework 7 of resonant cavity 11, be arranged in resonant cavity 11 vibrating diaphragm, be fixed on the fixedly magnetic circuit component 10 on the framework 7, the magnetic circuit component that can be fixed 10 drives the voice coil loudspeaker voice coil 8 of doing axial motion; The outer peripheral face of voice coil loudspeaker voice coil 8 is connected on the inner peripheral surface of framework 7 through location elastic wave sheet 9; The periphery of vibrating diaphragm is bonded on the outer peripheral face of voice coil loudspeaker voice coil 8, and the neighboring of vibrating diaphragm is bonded in the inner rim portion of framework 1 through elastic edge 6.Fixedly magnetic circuit component 10 is provided with the common structure that structure can adopt those skilled in the art to know; The magnetic field interaction that magnetic field that feasible fixedly magnetic circuit component 10 produces and energized coils 8 produce; Thereby drive voice coils 8 motion, fixedly magnetic circuit component 10 drive voice coils 8 are moved is provided with the common structure that structure adopts those skilled in the art equally and known.Those skilled in the art knows; When having tone currents to pass through in the voice coil loudspeaker voice coil 8; Can produce the magnetic field that changes with tone currents, the magnetic field that magnetic loop produces in this magnetic field and the fixing magnetic circuit component 10 interacts, and makes voice coil loudspeaker voice coil 8 generation axial vibrations; Be with the vibrating diaphragm vibration sounding, the frequency response curve of this loud speaker is shown in the red curve among Fig. 6.
Black curve among
Fig. 6 is the frequency response curve of the loud speaker of the traditional vibrating diaphragm assembling of employing; The tradition vibrating diaphragm is the diaphragm of the shape in the form of a truncated cone mentioned in the background technology; Relatively red curve and black curve can be seen; Offer paired perforation 2 and in perforation 2, cover the loud speaker that the vibrating diaphragm assembling of flashing 3 forms and to reduce the spike of medium-high frequency section like 1000 Hz ~ 10000Hz frequency range; The frequency response curve of this loud speaker medium-high frequency section is comparatively level and smooth, has improved the sound effect of medium-high frequency section, more can reflect primary sound truly.Usually the frequency range that can hear of people's ear is 20 Hz ~ 20KHz, and it is divided into basic, normal, high three frequency ranges, low-frequency range 20 Hz ~ 640 Hz wherein, Mid Frequency 640 Hz ~ 2500 Hz, high band 2500 Hz ~ 20KHz.
to sum up; In the conical inclination portion of loundspeaker diaphragm, offer perforation, cover flashing in the perforation, can reduce the spike of medium-high frequency section on the loud speaker frequency response curve effectively; Improve the auditory effect of loud speaker, make sound more truly, more pleasing to the ear.
