There are still more angle straight flanges, are still relatively also easy to produce standing wave.
Any sound box can be considered the cabinet of performance Yu quality existing defects once there is standing wave generation, because of standing wave
It is sound wave extra in music playback, is the sound wave not having in music program source signal, a kind of disengaging music letter can also be regarded as
From vibration wave, this standing wave can not only be participated in the movement of the diaphragm of loudspeaker in cabinet the cabinet of number control with a kind of energy mode,
To interfere the normal sounding of the diaphragm of loudspeaker, sound coloration is formed, it can also be with the superimposed prominent energy damages speaker of monochromatic wave
The energy balance of different frequency when resonance causes resonance effect the phenomenon of sound hangover or acoustic pressure unevenness, sound coloration, sound hangover occur
Phenomenon makes frequency sense of hearing ambiguous, is exactly the harmonic series property for changing musical sound for resetting music, will have to human body
The pairs of human health of music sound wave characteristic changing of health benefit has the noise properties of damage effect, thus reduces the humorous of speaker
The quality for the pure performance and music playback fidelity of shaking.
Summary of the invention
The problem to be solved in the present invention is that existing speaker is also easy to produce standing wave, the pure performance of resonance of speaker and music weight
The lower defect of fidelity is put, a kind of acoustic space appearance speaker is provided, the acoustical behavior of speaker system can not only be improved
And its quality, and changing method can be used to need to adapt to a variety of condition speaker acoustic space appearance appearance at different conditions
It wants, improves speaker quality, easy to use, adaptability is good.
The embodiment of the present invention provides a kind of acoustic space appearance speaker, including speaker case cylinder, top and bottom surface, the sound
Case case cylinder section is the linear curved surface appearance of more ovum, and the top and bottom surface are the appearance of micro-arc concave curved surface, recess court
To the speaker case cylinder.
Preferably, the section of the speaker case cylinder horizontal direction is the linear curved surface of more ovum.
Preferably, the horizontal inner edge of the top and bottom surface is micro-arc, to form micro-arc concave curved surface appearance
Further improvement to above-mentioned technical proposal is that the speaker case cylinder is the linear curved surface appearance of more than 1/2 ovum of facade.
Further improvement to above-mentioned technical proposal is that the speaker case cylinder is the linear curved surface appearance of more than 1/4 ovum of facade.
Acoustic space appearance speaker of the present invention, beneficial effect compared with prior art is:
Mainly with the linear appearance curved surface appearance of the more ovum in speaker case cylinder cross section and speaker top, the recessed appearance song of bottom micro-arc
Face appearance combines, and any face in the appearance sound box inner space is symmetrically closed without angled relationships or plane with side
System, therefore standing wave item caused by the speaker in this kind of appearance appearance space is substantially eliminated because of angled relationships or plane symmetric relation
Part, while also to reduce box house sound wave to the reflection interference condition at the diaphragm of loudspeaker back side, under the limited conditions maximum limit
Degree ground is that pure the pure of especially low frequency speaker resonance quality of speaker resonance quality provides sound physical properties condition；
Internal capacity is bigger on same apparent size, than the adaptability that cylindrical space application has more product；Its
With more the pure performance advantage of speaker resonance especially lower frequency speaker resonance, while also there is music playback performance and matter
Measure the higher advantage of fidelity；
The speaker can not only improve the acoustical behavior and its quality of speaker system, and can be at different conditions using change
Change method with adapt to it is a variety of under the conditions of speaker acoustic space appearance appearance needs, it is linear that guarantee ought unconditionally implement complete more ovum
When curved space appearance appearance, negative influence of the standing wave generation to speaker performance and quality is mitigated or reduced as far as possible, is had general
Time speaker acoustic technique practical value and electroacoustic techniques development promote meaning.
