Description
Technical field
The present invention relates to a kind of acoustic construction design, relate in particular to a kind of acoustic construction that adopts passive vibrating diaphragm unit.
Background technology
When loudspeaker unit vibrates being subject to Electromagnetic Drive, the sound wave of low frequency is because the size of wavelength ratio loud speaker is large, cause the low-frequency sound wave of loud speaker front and back to be cancelled out each other, so need to be by the low-frequency sound wave isolation (airtight) after loud speaker or paraphase out.Conventional paraphase mode is phase-reversing tube or passive vibrating diaphragm unit.For using the structure of passive vibrating diaphragm unit, because passive vibrating diaphragm unit is placed on a side of loudspeaker unit or casing often, receive passive starting of oscillation after the vibration of loudspeaker unit, then send sound wave.The shortcoming of this structure is, the sound wave that passive vibrating diaphragm unit sends from loudspeaker unit has different synthetic effect (having phase difference) along with the different of LisPos, causes the location of distortion, time delay and sound field inaccurate.
In addition, consider the feature of audio frequency vibration, its frequency and wavelength have just brought special requirement to acoustic design inside and outside audio amplifier, for example external dimensions, inner acoustic construction, material etc.So the design of sound box system often has unique threshold, can not only consider its appearance effect.If consider from starting points such as its outward appearance, structures, often can not take into account the acoustical behavior of sound box system.Therefore,, for the magnetic speaker of certain excellent performance, its audio amplifier design is also often limited, can not adapt to fast the appearance requirement in multiple different applied environment.
Due to the development of wireless technology, radio play (bluetooth and AIR PLAY) becomes the broadcast mode of current main flow, and the complicated connecting line between traditional audio amplifier and player no longer exists.If so audio amplifier and household articles can be combined better, instead of audio amplifier is had an independent existence in family, both reduce the area that audio amplifier takies, also make whole household seem brevity and lucidity more.This just need to have a kind of audio frequency Radiation Module, as a standard component, can be easily with household in object with annular seal space carry out combination, such as light fixture, furniture etc., derive very abundant application.
