Abstract
The utility model relates to a reflex solid sound cover which can position the sound field. The utility model comprises a reflex cover and a loudspeaker; the reflex cover is an arched concave surface; the front of the reflex cover is provided with a loudspeaker; the utility model can position and reflex the sound field through the reflex cover; the utility model can strengthen the effective volume and quality of the sound resource in the reflex area; the utility model can enhance the noise ratio; the utility model not only has the insulation effect to the outside noises but also limits the transmission arrange of the sound field; the utility model has a small interference to the environment; and the utility model needs not to contact with the human body and can receive a hifi sound.
Description
The utility model relates to sound technique, is a kind of reflection-type stereo sound cover of locating sound field.
The existing stereo set of raising one's voice all has certain sound field scope when propagating sound, loud speaker or audio amplifier are used in use mostly when the sound field of relative broad range, often use earphone propagating among a small circle, the former locating effect of sound field is poor, is difficult to avoid other sound field and interference of noise; The latter then needs to contact human body, and it is convenient inadequately to use, and has certain limitation.
The utility model locatees sound field, insulating noise for the defective that overcomes prior art and exist provides a kind of, do not contact human body, the reflection-type stereo sound cover of located for sound field easy to use.
The utility model adopts following technical scheme:
Can locate the reflection-type stereo sound cover of sound field and be made up of reflector, loud speaker, reflector is an arc-shaped concave, is placed with loud speaker before the reflector concave surface.
The utility model also adopts following technical scheme:
The reflector concave surface can be folding face, hyperbola or hemisphere, and the reflector diameter is 30 centimetres to 100 centimetres.
Loud speaker is the multichannel more than two, the positive reflector concave surface that points to of loud speaker.
The utility model accompanying drawing is a structural representation.
Below in conjunction with accompanying drawing in detail the utility model is described in detail.
Can locate the reflection-type stereo sound cover of sound field is made up of reflector 1, loud speaker 2, reflector is an arc-shaped concave, concave can be folding face, hyperbola or hemisphere, required according to sound field, the reflector diameter can be 30 centimetres to 100 centimetres sizes, is placed with loud speaker in reflector concave surface the place ahead, the positive reflector concave surface that points to of loud speaker, loud speaker is two a stereo channels, also can place the loud speaker of many multichannels as required.The utility model in use, listener 3 as long as in sound cover the place ahead 20 centimetres to 50 centimeters, need not contact with the sound cover and get final product uppick high-fidelity music center clearly.
The utility model utilizes reflector that the sound field of loud speaker is reflected and the location, strengthened the volume and the quality of effective source of sound in the echo area, it has strengthened signal to noise ratio, not only noise has insulating effect to external world, also limited the spread scope of sound field, little to environmental interference, do not need to contact human body, easy to use.
