Abstract
The present invention relates to a kind of passive radiators.A kind of passive radiator that low-frequency effect is good, the ring of vibrating diaphragm outer is pasted onto including vibrating diaphragm and with adhesive, the vibrating diaphragm is the upper layer film bonded with adhesive and lower membrane, the upper layer film is carbon fiber board hot-forming after impregnating resin, and the lower plywood is the metallic plate coated with vulcanized rubber.The vibrating diaphragm of passive radiator of the present invention is combined using carbon fiber board hot-forming after impregnating resin and with the metallic plate of vulcanized rubber cladding, has the advantages that appearance is beautiful, low-frequency effect is good.
Description
Technical field
The present invention relates to a kind of passive radiators.
Background technology
Shake basin, is the important component of loud speaker.In loud speaker, voice coil can produce after connecting audio signal in magnetic field
Raw sharp pounding, voice coil, which is integrally fixed at, to shake on basin, and the vibrations of voice coil while the vibrations for driving the basin that shakes, the basin that shakes vibration force air
It shakes, to make a sound.The basin that shakes usually is made of the ring of pelvic cavity and pelvic cavity outer, and the effect of wherein pelvic cavity is to connect
Vibration to be received simultaneously to transmit vibration, the effect of ring is to be fixedly connected pelvic cavity, and by the ring of arch the Vibrant buffer of pelvic cavity,
To ensure to shake, basin can integrally transmit sound vibration signal.Pelvic cavity is broadly divided into cone, bulletproof cloth basin, wool basin, gold by material
Belong to several forms such as basin, pottery pot, PP basins.The material of ring mainly has thermoplastic polyurethane elastomer rubber, on cloth base material
Paste resin, PU, papery.
Passive radiator is the active cell in speaker（Shake basin）To carrying out passive sounding under the drive of air in babinet
Component, commonly used in adjustment bass so that designer can adjust the tone color of speaker entirety.Passive radiator has vibrating diaphragm and vibrating diaphragm
The ring of outer forms, and ring material is similar with the ring material for the basin that shakes.The structure and material for adjusting vibrating diaphragm and ring, can obtain
Obtain different acoustical qualities.Such as 2016111130050 disclose a kind of high performance speaker and shake basin or passive radiator, ring
Material is styrene analog thermoplastic elastomer, since the rigidity and resilience performance of styrene analog thermoplastic elastomer are very suitable for shaking
Basin or passive radiator, thus it is obtained shake basin or passive radiator has elastic good a, easy processing, good excellent of acoustic efficiency
Point.
Invention content
Technical problem to be solved by the invention is to provide a kind of good carbon fiber board composite passive radiation devices of low-frequency effect.
A kind of carbon fiber board composite passive radiation device that low-frequency effect is good, including vibrating diaphragm and be pasted onto outside vibrating diaphragm with adhesive
The ring on edge, the vibrating diaphragm are upper layer film bond with adhesive and lower membrane, and the upper layer film is is hot pressed into after impregnating resin
The carbon fiber board of type, the lower plywood are the metallic plate coated with vulcanized rubber.
Further, the metallic plate is steel plate or aluminium sheet.
The vibrating diaphragm of passive radiator of the present invention uses after impregnating resin hot-forming carbon fiber board and with vulcanized rubber packet
The metallic plate covered is combined, and has the advantages that appearance is beautiful, low-frequency effect is good.
Description of the drawings
Fig. 1 is the vertical view of passive radiator of the present invention.
Fig. 2 is the cross-sectional view of passive radiator of the present invention.
Fig. 3 is the cross-sectional view of vibrating diaphragm in Fig. 1 of the present invention and Fig. 2.
Specific implementation mode
With reference to embodiment, the present invention will be described in detail, and embodiment is only the preferred embodiment of the present invention,
It is not limitation of the invention.
Embodiment
As shown in Figs. 1-3, the good carbon fiber board composite passive radiation device of a kind of low-frequency effect, including vibrating diaphragm 2 and use gluing
Agent is pasted onto the ring 1 of 2 outer of vibrating diaphragm, which is the upper layer film 21 bonded with adhesive and lower membrane 22, wherein upper layer
Film 21 is carbon fiber board hot-forming after impregnating resin, and lower membrane 22 is the aluminium sheet 222 coated with vulcanized rubber 221.
Since the vibrating diaphragm of the passive radiator coats for carbon fiber board and vulcanized rubber 221 hot-forming after impregnating resin
Aluminium sheet 222 be combined, therefore have the advantages that low-frequency effect is good.
Several embodiments of the invention above described embodiment only expresses, the description thereof is more specific and detailed, but simultaneously
It cannot therefore be construed as limiting the scope of the patent.It should be pointed out that coming for those of ordinary skill in the art
It says, without departing from the inventive concept of the premise, various modifications and improvements can be made, these belong to the protection of the present invention
Range.Therefore, the protection domain of patent of the present invention should be determined by the appended claims.
