Description
Technical field
The utility model relates to loudspeaker techniques field, is specifically related to a kind of medium conduction micro drives loud speaker.
Background technology
Common loud speaker is by air borne sound, as: electronic (moving-coil) loud speaker, magnetic speaker, static (electric capacity) loud speaker, piezoelectricity (crystal) loud speaker, electric discharge (ion) loud speaker; Common loud speaker is to be detected and produced vibration by ear-drum, and spiral organ completes phonosensitive process, has auditory nerve to pass to auditory center, then hear sound, and this process that receives sound by ear-drum can cause damage to auditory system for a long time.The driving of preaching of so-called medium, strain the meaning of the word is to vibrate meson (as plastics by driver, metal, wood, bone etc.) generation sound, sound rather than air transmission because medium is preached, so have many good qualities, 1. can intercept noise jamming in noisy environment, 2. ear can keep free and open state, bring the medium earphone of preaching also can hear sound around, while moving out of doors, can hear other sound, effectively reduce dangerous, 3. because medium is preached and is not by air borne audio reception, can mask the outside noise that air borne brings, make tonequality high-fidelity, effectively receive the authenticity of sound, reduce the partial failure of audio frequency in air borne, this is the medium low leakage of part-sound having superiority most of preaching just also.
Summary of the invention
For above-mentioned technical problem, the utility model provides a kind of reasonable in design, long service life, the medium conduction micro drives loud speaker of stable performance degree.
Realize the technical solution of the utility model as follows:
Medium conduction micro drives loud speaker, comprise basin frame, vibration output slab, magnetic circuit base, described basin frame is between vibration output slab, magnetic circuit base, between three, form assembly space, in assembly space, be provided with the magnetic circuit system that is placed in magnetic circuit base, be enclosed within the voice coil loudspeaker voice coil of magnetic circuit system outside, and be arranged on magnetic circuit system the support vibrational system for supporting vibration output slab, described support vibrational system adopts nylon material to make.
Adopt above-mentioned scheme, support vibrational system is positioned over to basin frame inside, and be combined with magnetic circuit system, form suspension built-in, be different from so general vibrating speaker, the support vibrational system of general vibrating speaker is bonding by glue with vibration output slab, this operating procedure has a lot of drawbacks, such as glue cohesive force is not firm, easily in the process of work, come off, or after long work, glue is easily aging, in addition, by the parts of adhesive bond, owing to being subject to the impact of binding agent, can produce very large distortion, mainly because the effective period of binding agent, after long work, the high temperature producing, binding agent there will be in various degree aging, there will be severe binding agent carbonization, and make whole vibrational system in paralyzed state.Also have the vibration unit of general vibrating speaker to support by playing ripple, general bullet ripple is a cotton, smears one deck glue thereon, after long work, the rigidity that plays ripple can change, and makes vibrational system produce skew, causes serious distortion.The utility model is to adopt support vibrational system and magnetic circuit system to combine, supporting vibrational system is directly bonded on magnetic circuit system, thereby can effectively evade above-mentioned drawback, reduce the situation that occurs serious distortion or vibrational system paralysis due to the after vibration loud speaker that works long hours; In addition, the material nylon that the support vibrational system in the utility model adopts is made, because its degree of crystallinity is high, fusing point is obvious; Case hardness is large, abrasion performance, coefficient of friction are little, have self lubricity and noise reduction.Cryogenic property is good, has certain thermal endurance (can use below 100 degree).These characteristics that have just because of nylon, the particularly large and noise reduction of hardness, play vital effect for vibrating speaker, the hardness of nylon can make whole vibrational system have more rigidity, there will not be variation in rigidity after long work, and make vibrational system produce skew, cause serious distortion, the noise that the noise reduction of nylon produces can better shield vibrational system vibration time.Thereby the utlity model has reasonable in design, stable performance, the advantage of long service life.
Further, described support vibrational system comprises the support ring of annular, is provided with the vibration module of Curved at support ring inwall.Unreasonable owing to designing in existing General Oscillation speaker support vibrational system, the audio distortion that the vibrational system of this shape is sent is larger, and sound is dry and astringent, and Design of Vibration System is become to bending shape, is mainly in the time that vibrational system is vibrated, to play cushioning effect.Compliance can increase whole vibrational system vibration time, adds the material characteristic that supports vibrational system itself in addition, can represent different music styles.
Further, described vibration module comprises the central block in support ring middle part, for connecting the Curved connecting portion of central block and support ring inwall.
Further, on described central block, be wholely set and be useful on the support column being connected with magnetic circuit system.
Further, the thickness of described vibration module is lower than the thickness of support ring.
