Description

BACKGROUND OF THE INVENTION Field of the Invention [0001] The present invention relates to a speaker for non-directional sound and 360-degree omnidirectional image,

The present invention relates to an omnidirectional sound and a 360-degree omnidirectional image speaker, and more particularly, to a CCTV camera lens for image realization at the center of a speaker and a cone- And an omnidirectional sound and a 360-degree omnidirectional speaker which satisfy all omnidirectional images of an image in addition to the omnidirectional sound according to the omnidirectional sound.

Generally speaking, the speaker can realize the range of the audio frequency ranging from 20Hz to 20KHz. Most of the existing speakers are made of the integrated type in which the diaphragm and the dust cap are connected.

The dust cap is a function to prevent the inflow of iron contained in the dust or dust around the speaker, and when the surrounding iron is sucked up due to the formation of a strong magnetic field of about 1 tesla or more, an abnormal sound is generated. The dust cap is integrated with the diaphragm.

Therefore, it has been evaluated that the connection of the conventional speaker with the dust cap has the function of preventing the sound distortion, but recently, it has been accepted that there is no problem in realizing the sound of the speaker itself even when the dust cap is detached.

For this reason, most of the recently released loudspeakers are usually product types in which a pole plate is emptied at the center of the speaker and a tweeter speaker is attached thereto.

A tweeter speaker is a type of speaker that plays a high frequency range and reproduces a frequency range of about 3 KHz to 20 KHz.

However, past and recent loudspeakers have been transformed into various forms for applications that are limited to acoustic implementations, but they have not been developed until extended use speakers that include acoustic implementations.

Furthermore, conventional loudspeakers are only directional speaker types that propagate in one direction only when implementing acoustics. That is, the directional loudspeaker transmits a sound in only one direction when the loudspeaker is transmitting sound, and thus limits the direction to the sound transmission.

On the other hand, most of the patent documents disclosed in the following prior art documents are only disclosed in such a manner that a speaker is combined with a video apparatus or a video apparatus is combined with a sound apparatus.

1 and FIG. 2, the speaker 100 according to the present invention includes a first mounting portion 110 for mounting a camera member on an upper portion thereof and a second mounting portion 110 for mounting the reflection member on the first mounting portion at a predetermined spaced- The first mounting portion 110 and the second mounting portion 120 are all formed in a cylindrical shape, but the present invention is not limited to a cylindrical shape, and various shapes are possible.

2, the first mounting portion 110 includes a first plate 111, a second plate 112, a permanent magnet 113, a frame 114, a vibration plate 115, and a camera lens 119 ) And the like, and more detailed description is as follows.

The first mounting portion 110 is a kind of cover member and the first plate 111 is embedded in the upper end of the first mounting portion 110 so as to have a T shape and the second plate 112 is fixed to the first plate 111 And the permanent magnet 113 is placed between the first and second plates 111 and 112. The first plate 111 may be the same as the term of the first yoke And the second plate 112 may be the same as the term of the second yoke.

Particularly, the lower part of the center of the first plate 111 is used as a pole piece fixing part 111a, and a pole piece can be used as a pole plate. , The camera lens 119 is assembled and fixed to the assembly place of the pole piece fixing portion 111a, which is the pole piece assembly seat in the existing speaker. Of course, the camera lens 119 is interpreted as including a camera.

The frame 114 is provided at the lower end of the second plate 112 in addition to the permanent magnet 113 and the frame 114 is provided inside the frame 114 One end of the diaphragm 115 is fixed to the bobbin 117 having one end around the pole piece fixing portion 111a and the other end is fixed to the frame 114 .

The voice coil 116 is wound around the bobbin 117 and the bobbin 117 is wound around the bobbin 117. The voice coil 116 is wound around the bobbin 117, And the damper 118 is disposed between the frame 114 and the damper 118. The damper 118 helps to vibrate the vibration plate 115 and the voice coil 116 while controlling the driving force thereof, It goes crazy.

The second mounting portion 120 is formed in a cylindrical shape as shown in FIG. 1 and FIG. 2, and includes a reflection plate 121 installed at the upper center of the second mounting portion 120.

The reflection plate 121 is formed as a cone with a vertically upward direction and forms a mirror coating layer 122 coated on a surface portion as shown in FIG.

The mirror coating layer 122 coated on the reflection plate 121 reflects a 360 degree omnidirectional view in the same manner as a mirror so as to allow the camera lens 119 to photograph images of omnidirectional view. So as to obtain a sharp image quality of a photographed image.

The mirror coating material used for the mirror coating layer 122 is preferably platinum or titanium.

In most cases, mercury is used as a mirror coating material. Such mercury materials can not block ultraviolet rays by about 70%. As the mirror coating material is mercury, harmful substances harmful to human body such as allergic dermatitis and nerve paralysis are caused. And the uniformity of the lens precision is lowered during the coloring process of the mercury, resulting in distortion of the image to the visual field and deterioration of the image quality of the image. When the scratches or scratches occur, It has the disadvantage of making people grow older.

In contrast, platinum and titanium materials do not require the use of dyes, they have excellent image clarity and resolution, they do not distort images even when scratches or scratches occur, It is preferable to use platinum or titanium as a mirror coating material because it is expected to have a clear blocking effect of ultraviolet rays as well as an advantage of ensuring the clarity of an image even in a visible field environment.

The speaker 100 according to the present invention includes a carrera lens 119 fixed to the pole piece fixing portion 111a of the first plate 111 in the first mounting portion 110, A plurality of springs S and an anti-vibration pad P are formed on the inner side of the bobbin 117 and the diaphragm 115 from the pole piece fixing portion 111a to prevent vibration of the anti- P in which the camera lens 119 is fixed.

That is, the camera lens 119 can be interlocked and vibrated in accordance with the vibration of the diaphragm 115. The vibration of the camera lens 119 is transmitted to the image of the visual field reflected from the reflection plate 121, It is necessary to stay in a non-vibration state without interlocking in spite of the vibration of the diaphragm 115 due to the problem that a sharp photographic image can not be secured. For this, a plurality of the springs S and the vibration- .

In other words, the plurality of springs S are fixed at one end to the inner surface of the bobbin 117 and the diaphragm 115 from the pole piece fixing portion 111a while the other end is fixed to the outer surface of the vibration- In order to fix the camera lens 119 due to the insertion hole formed along the inner length of the anti-vibration pad P, the anti-vibration pad P is fixed at a predetermined interval between the springs S, The camera lens 119 is maintained in a non-vibration state.

For example, when the diaphragm 115 vibrates and generates sound, the vibration transmitted through the diaphragm 115 can be expected to spread and weaken the vibration intensity through the plurality of springs S, The vibration of which vibration intensity is weakened from the spring S is absorbed through the vibration preventing pad P so that the camera lens 119 can maintain the non-vibration state.

If the number of the springs S is further increased or the thickness and the thickness of the vibration-proof pad P are increased, The camera lens 119 can be kept in a non-vibration state by including other factors such as overlapping.

As described above, in the speaker 100 according to the present invention, the permanent magnet 113 supplies a strong and continuous DC magnetic flux to the air gap of the magnetic circuit to which the voice coil 116 is to be moved, 116 receives the electric input from the terminal to generate the rotary chuck. The diaphragm 115 receives the motion of the voice coil and generates pressure fluctuations of the air to reproduce the electric signal by voice.

Particularly, according to the present invention, the diaphragm 115 can be easily assembled to the diaphragm 115 without requiring a dust cap to prevent the inflow of the iron component contained in the dust or dust, And a camera lens 119 is assembled to the camera body 111a.

Therefore, in the operation of the speaker 100 according to the present invention, the sound reproduced from the diaphragm 115 formed along the outer circumference around the camera lens 119 is transmitted to the second And is reflected by a conical reflecting plate 121 provided at an upper end of the mounting portion 120. The reflecting plate 121 has a characteristic that it is reflected in an omnidirectional manner unlike a conventional speaker having a directivity, The image can be collected by the camera lens 119 positioned at the center of the diaphragm 115 through the reflection plate 121 from 360 degrees.

Of course, it is preferable that the camera lens 119 is a CCTV camera lens capable of capturing an image of a vision that can be monitored in real time in a real time, A utility driver package for tremor correction can be applied to the CCTV camera so that vibration correction due to sound reproduction of the diaphragm can be performed. For example, a utility driver package of AMD Steady Video (AMD Catalyst) can be provided .

As described above, the speaker of the present invention is a technique in which sound and image are fused, and it is characterized in that it is possible to take a 360-degree panoramic image of a clock (an image) The speaker of the present invention can be utilized as a video call system using 360 degree omnidirectionality.

Especially, when 360 degree image is used in the case of creating a virtual reality service, 360 degree image is used most frequently. When a 360 degree image is used in a video call, a video call is divided into a form of a more realistic call system Which is expected to create a market.

In addition, when a variety of product groups such as a TV, a monitor, a speaker, a CCTV, a camera, a screen, and an illumination using a visual and auditory sense are manufactured as one fusion device and the feature of the speaker technology of the present invention is applied, Its range of use can be infinite.

In addition, when using audio and video in conjunction, it has the advantage of widening the area of information exchange with many product groups, and when displaying and transmitting letters on LCD screen and switching from sound to sound, You can feel more intimacy.

Finally, since different methods of visual and auditory products are used, that is, light and sound, both methods can be implemented in WAVE form. Therefore, in terms of technology convergence and product convergence possibility, It is expected to be highly utilized.
