Specific implementation mode
To make the above purposes, features and advantages of the invention more obvious and understandable, below in conjunction with the accompanying drawings to the present invention
Specific embodiment be described in detail.
Fig. 1 is the dimensional structure diagram of the sound wave reflection unit in one embodiment of the invention.Fig. 2 is that sound wave is anti-in Fig. 1
The front view of injection device.Referring to Fig.1 with shown in Fig. 2, sound wave reflection unit 1 includes：
Soft reflector plate 11, soft reflector plate 11 include the central area that fringe region 11a and fringe region 11a are enclosed
11b, at least central area 11b are deformable；
And control-rod 12, the central area 11b that one end of control-rod 12 is held in soft reflector plate 11 make its deform shape
At overshooting shape reflecting surface 13.
Fringe region 11a is used for the fixation of soft reflector plate 11, such as is bonded on an annular element.Central area 11b has
There are two opposite faces, the supporting surface of one of face bar 12 in order to control, another face is reflecting surface 13.
In one scheme, the material identical of the fringe region 11a and central area 11b of soft reflector plate 11 are soft when processing
Matter reflector plate 11 may be integrally formed.The material of soft reflector plate 11 can be silica gel or thermoplastic elastic material
(Thermoplastic Elastomer, TPE).In another scheme, the material of fringe region 11a and central area 11b is not
Together, the two can bond or existing combination is processed together.The material of fringe region 11a can be thermoplastic elastomer (TPE) material
Expect (Thermoplastic Elastomer, TPE), the material of central area 11b can be silica gel.
The soft material of central area 11b can have multilayer, such as supporting surface has the film layer of enhancing toughness, reflecting surface
13 film layers that there is enhancing reflecting effect, reduce sound-absorbing.
In one scheme, the thickness of central area 11b is uniform.In another scheme, central area 11b is from edge to center
Point is gradually thinning.The central area surfaces 11b difference thickness degree, can realize protrusion of different shapes, corresponding reflecting effect
Difference, sound wave is converging or diverging with degree difference, and then audio is also different.
One end of control-rod 12 is held in the central area 11b of soft reflector plate 11, and the other end can be controlled by machinery even
Bar can also be controlled by stepper motor.
The forward travel distance of control-rod 12 towards soft reflector plate 11 is different, and the deformation extent of central area 11b is different, reflection
The protrusion degree in face 13 is different.When Fig. 3 and Fig. 4 is the 12 forward travel distance difference of control-rod in Fig. 2, sound wave is different in protrusion degree
Reflecting surface 13 on different reflection angle schematic diagrames.
With reference to shown in Fig. 3, the forward travel distance of control-rod 12 towards soft reflector plate 11 is smaller, the deformation of central area 11b
Degree is smaller, and the protrusion degree of reflecting surface 13 is also smaller.Correspondingly, the sound wave that the sound source opposite with reflecting surface 13 is sent is through reflection
After face 13 is reflected, propagated towards close to Sounnd source direction.
With reference to shown in Fig. 4, the forward travel distance of control-rod 12 towards soft reflector plate 11 is larger, the deformation of central area 11b
Degree is larger, and the protrusion degree of reflecting surface 13 is also larger.Correspondingly, the sound wave that the sound source opposite with reflecting surface 13 is sent is through reflection
After face 13 is reflected, propagated towards far from Sounnd source direction.
With reference to shown in Fig. 3 and Fig. 4, when the center of sound source face reflecting surface 13, sound source is through reflecting to form respectively towards left and right two
The sound wave that a direction is propagated, the sound wave can be equivalent to two sound channels, form stereophone.
Sound wave after reflection, has 180 degree phase change, can also modulate sound wave as needed whereby, realizes not unisonance
Effect.
In Fig. 1 to Fig. 4, it can be seen that 11 smooth surface of soft reflector plate, accordingly, the surface of overshooting shape reflecting surface 13
Also smooth.In other embodiments, if the central area surfaces 11b of soft reflector plate 11 can also be one centered on central point
Dry circular protrusion, accordingly, overshooting shape reflecting surface 13 are also several circular protrusions centered on central point.Overshooting shape reflects
13 surface of face can also have other shapes, the present invention to be not intended to limit this.The central area surfaces 11b of soft reflector plate 11 are not
Same smoothness can realize different reflecting effects, and sound wave is converging or diverging with degree difference, and then audio is also different.
The surface of central area 11b can also be against central area in addition to different smoothness using multiple control-rods 12
11b forms the reflecting surface 13 with multiple protrusions, to realize different sound wave reflecting effects, and then realizes different audios.
Control-rod 12 can be located at the central point of central area 11b, can also deviate central point.Fig. 5 is the control in Fig. 1
When bar deviates the central point of central area, the dimensional structure diagram of sound wave reflection unit.Fig. 6 is the sound wave reflection dress in Fig. 5
In setting, the reflection angle schematic diagram of sound wave on the reflecting surface.Control-rod 12, which is can be seen that, with reference to Fig. 6 and Fig. 3 is deviated to the right center
When the central point of region 11b, in the sound wave after reflection, the part reflected to the right accounts for the ratio reduction of total sound wave.It is appreciated that
When, when control-rod 12 is deviated to the left the central point of central area 11b, in the sound wave after reflection, the part reflected to the left accounts for total sound
The ratio of wave reduces.
Based on above-mentioned sound wave reflection unit 1, the present invention also provides a kind of sound equipments.In the sound equipment, sound wave reflection unit 1 with
Sound source is oppositely arranged.Specifically reflecting surface 13 is oppositely arranged with sound source.Sound source can be loudspeaker.Sound equipment can be vehicle-mounted sound
It rings.
In sound equipment, since control-rod 12 can be held in any position of central area 11b, thus, the center of sound source can
With as shown in Figure 3 and Figure 4, it is right against the center of reflecting surface 13, it can also be as shown in fig. 6, deviateing the center of reflecting surface 13.
In sound equipment, sound wave reflection unit can be driven with the button of multiple corresponding different acoustic effects, different key
In control-rod 12 cause the deformation extent of central area 11b different, to realize different audios；The stepper motor of control-rod 12
Control-rod 12 can also be driven to advance different amounts, realize different audios according to song lyric.
Although present disclosure is as above, present invention is not limited to this.Any those skilled in the art are not departing from this
It in the spirit and scope of invention, can make various changes or modifications, therefore protection scope of the present invention should be with claim institute
Subject to the range of restriction.
