Description

Hanging Scroll with Sound Playing Feature}

The present invention relates to a sound hanging scroll, and more specifically, a hanging scroll or roll screen type for attaching to a wall by making scrolls, landscape paintings, advertisements, etc., in the traditional way of hanging and viewing calligraphy. In addition to the inherent visual effects of the scroll, the lower scroll bar uses a hollow scroll bar and the sound generator module, battery, speaker, and an input device for control of play / stop, etc. It's about a phonetic scroll that allows you to add an auditory appreciation effect.

Conventional scrolls made for decorative or commercial use do not have a sound generating device, so that the viewer can recognize the picture or advertisement simply by viewing it, which does not provide an auditory effect. The hanging bar that has been used in the related art has a problem in that the sound device cannot be mounted inside because the inside is full or the inner space is narrow.

In addition, most traditional scrolls are wall-mounted, so the body is not firmly supported and the screen is pulled down even in the roll screen type. Physical force is applied to the scrolls during operation, which causes problems such as shaking and pushing.

Therefore, the present invention is equipped with a sound generating device inside using a hollow tubular barley bar, and both ends of the barley bar are sealed with a plug with a speaker hole so that sound can be emitted out and the human body sensing touch switch input device as an input signal device. Was devised to improve the above problems by using;

First, by using a tubular pontoon bar with a minimum inner diameter enough to embed electronic circuits and speakers, enclose both ends of the pontoon bar plugs with perforated speaker holes, and install sound generating modules, batteries, speakers, and input switches inside. It keeps its original appearance while providing a scroll that outputs sound. Instead of the normal push-type switch, the human body touch that generates an input signal by simply touching a part of a human body, for example, by hand. The purpose of the sensor method is to allow the user to easily manipulate the input signal without shaking or pushing because no physical force is applied to the scroll.

In addition, when mounting the speaker inside the barbed bar, a general speaker unit is used. This ensures that the speaker ball and the physical resonance space that are suitable for the size of the speaker unit to be applied to the inside of the barbed bar body or the plug portion have sufficient output. In the case of using a specially made scroll bar or stopper using a mold specially manufactured to mold it, it is a suitable method for mass production of low cost, and high cost mold cost for small quantity production of many kinds. Rather than using a box speaker with an integrated speaker unit in a self-resonant cylinder, and using a mold, a tubular bar-shaped bar can be used instead of a professionally made one. To reduce mold costs and reduce costs There is another purpose to provide the simplicity and ease on the small quantity batch production.

Figure 7 is a schematic perspective view of a box speaker applied to the present invention, Figure 8 is a view of the internal assembly of the hanging bar with a sound generating module using the box speaker and the touch switch input device according to the present invention in detail;

1 is an embodiment of a sound scroll according to the present invention is not much different from the conventional wall hanging scroll in appearance. 2 is a type of modern scrolls, also known as roll screens, which differs from conventional scrolls in that a winding device is included in the roll screen head 104 so that the screen 103 can be rolled up in need. The core of the present invention is a conventional scroll in which the sound generating device is mounted in the lower scroll bar (101) in FIG. 1 or 2 and outputs the sound in the direction of the scroll bar stoppers 105 and 106. It is to provide an audiovisual exhibition effect without any difference in appearance.

In this case, the basic configuration of the sound generator is shown in FIG. 3, wherein the music generating module 201 composed of electronic circuits receiving power from the battery 202 is input / output such as play / stop from the input device 203. It is a general case that is composed of a speaker 205 that outputs the sound stored therein when the music generation module used here is implemented by various methods of using simple melody IC, such as ADPCM or MP3 It is selected and used according to the requirements of the method such as the sound compression method or the method such as the sound source and the MIDI output device. In this case, when pressing the switch protruding outside, as shown in the internal assembly diagram of the foot bar with the sound generating module using the push switch shown in FIG. 4, the scroll is pushed or shaken.

FIG. 5 is a block diagram for each function using a touch switch input device including a human body sensing touch sensor module 208 and a touch sensing metal piece 207 instead of the push switch 203 as an embodiment according to the present invention. Or touch a part of the body to the touch sensing metal piece 207, the touch sensor module 208 detects this and sends an input signal to the music generating module to play the music. At this time, various types of human body touch switch input methods are used. Typically, the static electricity sensing method uses static electricity existing in the human body to use the flow of static electricity as an input to an amplifier when a part of the body contacts. As the oscillation method, the oscillation voltage is maintained at a minute size in normal operation, but when the human body contacts, the oscillation is stopped by changing the C value, which is a factor of oscillation, by the capacitance value of the human body to generate the input signal accordingly. There is a way to. The method of generating the input signal by the touch sensing method does not need to apply force to the main body as compared to the push switch method of applying physical force, so it does not push or shake when the input signal is manipulated, and the head portion or knob of the push switch protrudes to the outside. There is an advantage that does not. The touch-sensing metal piece 207 is made of a small conductor through electricity, which is a method of attaching the thin metal piece to a decorative shape so as not to be displayed on the outside, and incorporates a sound generating module using the touch switch input device of FIG. 6. As shown in the inner assembly diagram of a hanging bar, the hanging bar stopper 105 is made of a metal body through which the speaker ball is made to serve as a touch sensing metal piece 207 and connects it to the touch sensor module 208 of the music generating module. If the signal input device is a signal input operation even if the user swipes the scroll bar plug, there is no unnecessary appearance in appearance and there is an advantage in manufacturing. In this case, it is another method to manipulate the input signal by touching any part of the foot bar by making the foot bar rod material as a metal body so that the entire foot bar bar shell serves as a touch sensing metal piece.

7 shows an integrated box speaker 206 used in the present invention. As shown in the figure, this box speaker is provided with a speaker unit 211 and a resonance cylinder integrated into one case and a speaker hole 210 is integrated into a case, so that a separate resonance structure space is not required outside. Only the box speaker itself can output enough sound. This box speaker produces a small amount of resonant space suitable for the size of the speaker unit as in the case of a conventional speaker unit, so that a sufficient speaker output can be obtained by using a general tubular hanging bar material without having to fix it to the outer wall. It is convenient to do this and the cost is greatly reduced.

FIG. 8 is an internal assembly diagram of a pontoon bar incorporating the sound generating module using the box speaker 206 and the touch switches 207 and 208. The box speaker 206 is not attached to the outer wall of the pontoon rod and is just inserted into the inside. It is simple to manufacture and shows sufficient sound output. This eliminates the need to make a special resonance space structure so that the speaker unit is fixedly attached to the outer wall or plug of the hanging bar (101), thus simplifying the complicated manufacturing process for reducing the mold cost and fixing the outer wall. It is convenient to.

On the other hand, the sound hanging scroll according to the present invention is not only applied to the scroll type, but is a suitable method for adding sound effects to an object such as a tube. In the case of manufacturing a kind of model, etc., the scope of application can be expanded, and this also does not depart from the scope of the present invention.

As described above, according to the sound scroll of the present invention, by inserting the music generating module into the ball-shaped bar of the tube type with an empty inside and using a touch switch input device, unnecessary switch structures such as a switch head or a knob are provided. It does not protrude and can control playback or stop of sound output without shaking or pushing the scroll when input signal is operated. It provides audiovisual viewing effect of scroll.

In addition, by using a box speaker equipped with a self-resonant cylinder instead of the conventional speaker unit, the tubular bar hanging out without the process of fixing the speaker unit and attaching it to the mold by making the outer wall or plug of the foot bar to fit the size of the speaker unit. By simply inserting the box speaker using the rod, the sound is output by providing enough sound.
