Description
Technical field
The utility model is related to stereo set field, especially a kind of dynamic loudspeaker.
Background technology
Existing dynamic loudspeaker, it is maximum with cone basin loudspeaker market owning amount, application technology and production technology the most at
It is ripe.The diaphragm materials of cone basin loud speaker, to increase the performances such as its rigidity, internal damping and waterproof, are often existed based on paper pulp material
Mixed with the materials such as wool or kapok, silk, carbon fiber, flax in paper pulp.The material property of existing cone basin loud speaker, no matter how
Its basin body structure or construction are improved, sound reproduction quality also is difficult to obtain again further significantly to be promoted.
It is exactly that the flat electrodynamic type released of NXT companies is raised one's voice currently, there is another dynamic speaker on the market
Device.The radiation vibratory sound of the pronunciation vibration principle and traditional cone basin loud speaker of flat dynamic speaker is entirely different,
It is sticked together in one piece of special flat sheet and on special specified relevant position by a slight driver, when leading
This driver will drive this flat sheet to generate undulating vibratory and sound conduction is gone out when electric.Flat dynamic speaker
Transducing surface plate mainly have honeycomb boards, sandwich boards and pulp board.The also sound effective value of honeycomb boards is best, but relative cost is also most
It is high；Followed by sandwich plate；Pulp board is the material similar with the cone of conventional loudspeakers, and price is less expensive,
But sound quality is relatively poor.
The insufficient major embodiment of flat dynamic speaker is both ways：（1）Low frequency response is insufficient.Since NXT raises one's voice
The design of device is to use awave mode of vibration, therefore its air capacity that can be pushed is limited, so low frequency energy is inadequate, only
The medium-high frequency of about 100Hz-18kHz can be sent out, often makes one to feel that sound is bright and has a surplus and soft deficiency.It is typically necessary and matches
A standby super-bass loudspeaker box completes 100Hz low frequency playbacks below.For current effect, super woofer is raised with tablet
The linking of sound device still has not as good as in place of people's will, sound quality and the requirement of tone color distance Hi-Fi enthusiast also have relatively large distance.（2）Sound
Matter is to be improved.Since NXT panel speakers are that many small cell areas can be made mutually solely in plate face after being activated
Vertical random vibration sounding, rather than occur rigidity synchronous vibration, although therefore reduction sound have certain quality,
But there are certain distortions, therefore NXT panel speakers do not enter into high-fidelity music center field from modern yet, and sound quality needs into one
Step is improved.
