Embodiment
A kind of sound that the present invention is provided strengthens equipment, including base harmony focusing elements, and sound focusing component adopts surface
Has structure with concave surfaces, sound focusing component is arranged at beside user;The sound focusing component for after user's sounding, to user
Ear carries out sound reflection, improves the volume that user hears own voice.
Sound focusing component, is to refer to realize the structure of sound focusing or unit.Concave surface can be formed to ripple and concentrate reflection, make
The ripple that must be reflected focuses on certain region, the phenomenon for causing ripple to strengthen in the region, and above-mentioned principle is strengthened leading using in sound
Domain, that is, define sound focusing phenomenon.The sound focusing, refers to that concave surface is formed to sound wave and concentrates reflection, make reflected sound focus on certain
Individual region, causes sound in the especially loud phenomenon in the region.In life, indoor sound source sounding, sound wave encounter wall, smallpox
Plate, floor can produce reflection, and reflection law is deferred in sound reflecting, and incident acoustic wave is when to encounter reflector be concave surface, reflection
Sound is then concentrated in together, forms sound focusing, and this is similar with light focusing.
The sound focusing component of the present invention is set to:After user's sounding, sound reflection focusing is carried out to user ear, even if
The sound wave that must be reflected is focused in the ear of user, to improve the volume that user hears own voice.
Base, is easy for sound focusing component is placed on the structure beside user.It is unrestricted as an example, the base
With a carrying platform, directly sound focusing component can be placed on the working face beside user by the carrying platform.
Structure carrying platform being fixed on working face, such as adhesion arrangement, buckle structure are may be provided on the base
Deng fixture.
The base harmony focusing elements can be integrally formed structures, or be assembled together after being fabricated separately
Structure.The making material of the two can be the same or different, it is preferred that be made using the plastic material of lightweight.
Illustrated with modular construction, shown in Figure 1, sound focusing component group by way of assembling with base
Dress.Sound strengthens equipment 100, and including 110 harmony focusing elements 120 of base, sound focusing component 120 has with concave surfaces using surface
Structure, sound focusing component are arranged at the front region of the oral area 200 of user.
In the present embodiment, sound focusing component 120 is arranged on base 110 by support member 130.Fig. 2 illustrates this enforcement
In example, sound strengthens the structural representation of equipment, it is shown that side view, Fig. 3 A show that the sound strengthens the front view of equipment,
Fig. 3 B show that the sound strengthens the top view of equipment.Understand with reference to Fig. 2-3, the carrying platform of the base 110 is circular
Frame structure, the support member 130 are vertical bar component, and the sound focusing component 120 is surface in X-direction (i.e. transverse axis
Direction) indent concave structure.It is unrestricted as an example, in the present embodiment, the outward flange of the female parts of sound focusing component
Place is also associated with the marginal portion for extending, and the marginal portion can adopt slab construction, it would however also be possible to employ with certain radian
Curved plates structure.
Support member 130 can be arranged on base 110 by base articulated joint 140, and sound focusing component 120 can pass through
Sound focusing articulated joint 150 is arranged on support member.Specifically, as for example and not limitation of typical connected mode, described
The lower end side of support member 130 by hinge be arranged on base 110 hinged-support on, the support member 130 can respect thereto 110 adjust
Angle.It is shown in Figure 4, using said structure, when needed can by 120 respect thereto of sound focusing component fold up in order to
User carries, while the parameters such as the distance of 120 relative usage person's oral area of adjustment sound focusing component, angle can be played.
Further, the upper end side of support member 130 can also connect sound focusing component 120, the sound focusing by hinged-support
Component 120 can be relative to 130 adjustment angle of support member.It is shown in Figure 5, be by 120 relative support 130 of sound focusing component to
Structural representation after lower adjustment angle, it is clear that angle can also be adjusted upward with respect to the oral area of user.By using it is above-mentioned can
Folding, adjustable structure, user can adjust position and the angle of sound focusing component as needed.
Support member is in the present embodiment using fixed bar component, but those skilled in the art will be appreciated that the support member is also
Extension type bar component can be adopted as needed, can further reduce user and carry the sky needed during the sound stiffener
Between.
In another embodiment, sound focusing component concave surface can also be the spherical structure or flared structure of indent, pass through
After the concave surface of above-mentioned concave inward structure receives the sound that user sends, carry out sound reflection focusing to user ear, i.e., so that
The sound wave of reflection is focused in the ear of user.
Sound focusing component concave surface can also further adopt paraboloid structure, to adjust the position that sound wave is focused in ear.Institute
The concave surface for stating sound focusing component can be in the face of X-direction indent (i.e. indent in the horizontal), referring to the sound shown in Fig. 6-7
The sound focusing component of reinforcement structure;Can also be in the face of Y direction indent (i.e. indent in the vertical);Can also be for simultaneously in X
The face of axle and Y direction indent, referring to the sound focusing component of the sound reinforcement structure shown in Fig. 8-9, its structure similar to bowl.
The outer peripheral shape of sound focusing component can be rectangle, circular, or other polygons, ellipse.
When being embodied as, also multiple concave inward structures can be set on a sound focusing component.It is unrestricted as an example, than
Structure such as according to user's ear, arranges the concave inward structure at two intervals so that sound transmission on a sound focusing component
To after sound focusing component, left ear, auris dextra position are focused on by different concave reflections.
In another embodiment, the sound focusing component is arranged on support member by swivel joint, the sound focusing
Component is rotated by the swivel joint relative support.This structure is particularly suited for the inner concave of sound focusing component only one
The form of (such as X-direction or Y direction) indent on dimension direction, by the adjustable inner concave relative usage person ear of rotation
Position, and then adjust the position that sound reflection is focused on.
Present invention also offers a kind of voice strengthens mnemonic device.Voice strengthens mnemonic device includes that aforesaid sound is strengthened
Equipment, the sound strengthen the front region that equipment is placed on sound source.During use, first, sound reinforcement equipment is placed on into use
Family front region;User can need the position of sound focusing component and angle on regulation sound reinforcement equipment according to itself;Then
User's sounding, strengthening equipment by the sound carries out sound reflection to user ear, improves the sound that user hears own voice
Amount.As without using complicated energy resource supply structure and arrangements of electric connection, the present invention is without the need in fixed-site use, user
Oneself can carry out whenever and wherever possible studying English, read aloud text, recite the study such as formula.Meanwhile, compact of the present invention, weight
It is frivolous, with portable, real-time and easy-operating feature.
Foregoing description is only the description to present pre-ferred embodiments, not any restriction to the scope of the invention, this
The scope of bright preferred embodiment includes other realization, wherein can not by it is described go out or the order that discusses performing work(
Energy.Any change that the those of ordinary skill in field of the present invention is done according to the disclosure above content, modification, belong to claims
Protection domain.
