A computer comprising a predetermined program and displaying predetermined song accompaniment data selected by a user on the screen of the monitor, and simultaneously recognizing drum striking intensity information input through the interface unit 4 and displaying it on the screen. It consists of the part 5 as a basic characteristic.

Further, at the rear end of the computer section 5, a server section 7 for storing various data information necessary for accompaniment according to various songs and outputting the accompaniment data for a desired song from the computer section 5 is added. The computer unit 5 and the server unit 7 are connected to each other through an internet network 6, and the computer unit 5 can select desired song accompaniment data through the internet network 6. At the same time, an additional feature is to add a function of storing and displaying on the screen the song accompaniment data transmitted from the server unit 7.

In this case, the drum sensor 1 has a predetermined area and the conductive layers 13, 14 coated with a conductive material are formed on opposite surfaces, respectively, and the conductive wires 13, 14 have signal transmission wires 15, respectively. The upper and lower plates (11, 12) having a configuration connected to);

An insulating plate (16) fixedly installed between the upper and lower plates (11, 12) in a state where a through hole (17) having a predetermined area is drilled in the center thereof to electrically insulate the two conductive layers (13, 14);

The upper and lower plates 11 and 12 are filled in the through hole 17 of the insulating plate 16 and are hit by any one of the upper and lower plates 11 and 12 by the user. Carbon powder as a semi-conductive material (semi-powder) to rise and fall between the conductive layers (13, 14) of the conductive layer 13, 14 to an amount and intensity corresponding to the strength and to generate an electrical signal between the two conductive layers (13, 14) It is characterized by consisting of (18).

In addition, the sensor signal pre-processing unit 2 includes a sensor signal amplifying unit 21 for amplifying the weak hitting information output from the drum sensor 1 to a predetermined level; A filter unit 22 for removing a noise signal included in the hit information output through the sensor signal amplifier 21; Characterized in that the A / D conversion unit 23 for detecting the magnitude of the hitting information through a pulse width modulation method to convert to a digital signal.

Referring to the operation and effect of the device of the present invention configured as described above are as follows.

First, the drum sensor 1, which causes the player to strike, so that the strong and weak impact information according to the drum performance is generated as an electrical signal, the conductive layers 13 and 14 coated (coated) with a conductive material on the surfaces facing each other. Between the upper and lower plates 11 and 12 formed thereon, an insulating plate 16 having a predetermined area of perforated holes 17 is installed to be integrated, and a semiconductive material (semi-powder) is formed in the through hole 17 of the insulating plate 16. When the carbon powder 18 is filled and the blow is applied to any one of the upper and lower plates 11 and 12 by the user, the carbon powder 18 is the conductive layer 13 of the upper and lower plates 11 and 12. And 14, and descending by an amount and intensity corresponding to the strength, and an electrical signal is generated between the two conductive layers (13, 14).

At this time, the upper and lower plates (11, 12) and the insulating plate 16 is made of a material that does not break even if the user hits badly, when the actual production, the insulating plate 16 is placed on the lower plate 12 and bonded After fixing and filling a predetermined amount of carbon powder 18 into the through-hole 17 of the insulating plate 16, the top plate 11 is bonded by pressing and pressing to complete the production of one drum sensor (1).

Of course, the conductive layers 13 and 14 of the upper and lower plates 11 and 12 are connected to one end of the blow signal transmission wire 15, respectively.

On the other hand, the sensor signal pre-processing unit 2 may be correctly performed the pre-processing of the sensor signal under the following constraints.

That is, it should be used in the low voltage (5V) single power supply as a condition not to use a separate power supply for the computer, and should be configured to not use the A / D converter.

In the above, the intensity of the drum strike is normally proportional to the width of the pulsed signal generated when the drum sensor (1) strikes, when the sensor is configured as part of a dedicated device for the instrument, not connected to the computer unit (5) In the present invention, the sensor signal preprocessing unit 2 is composed of a sensor signal amplifying unit 21, a filter unit 22, and an A / D conversion unit 23 from the drum sensor 1 according to the present invention. After amplifying the weak hitting output information to a predetermined level and removing the noise signal, the striking strength of the drum sensor 1 was detected through a pulse width modulation (PWM) method.

In addition, after the sensor signal preprocessing, the blow signal of the drum takes a constant modulation method, and a demodulation circuit is required to demodulate the blow signal transmitted to the processing unit 3 after the sensor signal to obtain the blow information.

When demodulating the blow signal using the PWM method, a technique for measuring a pulse width irregularly generated by the microprocessor is required, and to demodulate the signal modulated by the AM method, the blow signal is transmitted through an A / D converter and a microcomputer. Measure the size of.

The sensor signal post processing unit 3 may be processed by a user's PC or may be processed through a specially designed dedicated device (dedicated microprocessor).

The difference between these two methods is that the PC requires Pentium-class high performance when processed by the PC, but the cost of making the device for drum learning becomes cheaper, and when processing through the dedicated device, the demodulation function of the sensor signal is a dedicated microprocessor. Can be used even if the performance of the PC is not so high.

In addition, after the sensor signal post processing unit 3, since the impact information of the drum performance is converted into a binary value reflecting the strength and strength of the computer, when the signal post-processing is performed by a PC, it is not necessary to think of a computer interface separately. In this case, it is necessary to transmit data to the PC, so the interface unit 4 must be installed.

Currently, a PC can receive data information from the outside by using a serial port, a parallel port, a keyboard interface, a PS / 2 port, a USB method, There are two ways to use the MIDI port, and a sound card installed in the PC.

In the above method of using a serial port, a method of transmitting to a PC is based on the RS-132 signal protocol according to an auxiliary synchronous communication method (asynchronous communication method) installed in the PC.

In addition, the parallel port is a method of using a parallel port for a printer interface installed in a PC. The parallel port can read or write data directly from a microprocessor without a special converter.

The keyboard interface uses a dedicated microprocessor that receives drum information between the PC and the keyboard installed on the PC, intercepts the keyboard signal, inserts the drum performance information into the existing keyboard signal, and sends it to the PC.

In addition, the PS / 2 port is a device used to interface a mouse or a keyboard in a current PC, and may be operated in the same manner as using the keyboard interface described above.

In addition, the USB port is the latest serial signal interface standard and data can be transferred to a PC according to this method. MIDI is a communication protocol between real musical instruments, and most multimedia PCs have such a port. You can enter

In addition, the sound card installed in the PC may receive a voice signal, convert the drum information into a voice signal and input it to the sound card.

As described above, according to the present invention, it is possible to input the drum drum or the hitting information into the computer with the drumstick or the hand with the feeling of the first, so that if you practice with such a device, you will be more familiar with the actual drum playing. Can be.

In addition, it can be used together with existing performance learning programs that use short-term repetitive learning to improve musical skills.

Second, unlike the previous method, the strength is transmitted to the computer according to the strength of the hitting information, unlike the method of transmitting only the presence or absence of the hitting information to the computer. This will give your drummer a realistic feel.

Third, the device can be used in musical learning or game programs by inputting the hitting performance of the drum performance in a realistic feeling, and can also be used as a musical instrument such as a real drum.

Therefore, users who are familiar with the device can play music through the device to maximize their enjoyment.

Meanwhile, the computer unit 5 recognizes the hit signal received from the interface unit 4, compares and evaluates the drum hit data among the music data built into the computer, and then evaluates whether the price is accurate, similar, wrong, or hitting time. It is displayed on the screen whether or not missed so that the user can evaluate the learning and at the same time induces the repeated use desires such as games.

At this time, the computer unit 5 downloads the song that the user wants to play from the server unit 7 through the Internet unit before receiving the hit from the drum sensor 1, and stores a song accompaniment signal in the computer unit and recognizes it by the user. It prints on the monitor screen in the form of color, dream, chart, text, and drum score for drum instruments.

These signals show which drum instruments of the drum set are to be hit, and proceed in real time as the song is played. The monitor screens of the computer unit 5 are all developed using a web browser window of the Internet, and the song accompaniment and The Drum Strike Sequence Signals operate in unison and move freely to STOP, PAUSE, PLAY, FORWARD, BACKWARD, TOP-OF-SCORE, and BOTTOM-OF-SCORE, allowing you to repeat the part of the song you want.

In addition, the Internet network 6 is composed of an Internet communication network connecting the server unit 7 and the computer unit 5, an Internet window, a URL associated with a domain name, and the like.

The computer unit 5 transmits information such as song accompaniment and musical instrument types selected by the user to the server unit 7, and transmits the information downloaded by the server to the computer unit 5.

On the other hand, the server unit 7 has a built-in program for use in the computer unit showing the user can select the song accompaniment database, the picture of the drum musical instrument, the blow signal sequence, etc., and sends it down to the computer unit at the request of the user whenever necessary .

At this time, the song database includes accompaniment of the song as MIDI signal data, which also stores data such as drum instruments, types of sounds, and batting order required for drum instrument performance.

As described above, the present invention is an apparatus that is integrated with the Internet, a computer, and a sensor for playing drums. The user selects a desired song from a song accompaniment database stored in an Internet server unit, downloads it to a personal computer connected to the Internet, and then plays the music. When activated, the software built into the computer unit (5) is configured for the drum performance along with song accompaniment. (Drum instrument set includes drum, snare drum, high sound tom, middle sound tom, low sound tom, crash symbol, and ride symbol. And the basic set is composed of 8 drum instruments such as hi-hat.) The order to be hit is displayed on the screen with signals divided into pictures, letters, colors, etc., and scored by distinguishing whether the hit information is hit correctly or wrongly or closely. Inspires learning motivation, interests and Show the process and the situation.

At this time, the signal displayed by the computer is the same as the actual drum instrument playing method.

The difference from the commercially available electronic drum equipment is that the sound source, the mechanism and the processing device that make the drum itself are not built in, but the sound of the connected computer is used.

And like a general game machine, it is represented by pictures, signals, letters, etc. and scored to show the accuracy of the hit on the monitor.

In addition, it shows that the accompaniment of the song that is downloaded from the Internet shows the score and the lyrics together so that you can enjoy karaoke and drum at the same time.

In other words, even those who can't see the score of the music or the drum at all can easily follow the performance of the drum. It is the same as that.

Users can play drums by repeating at least their favorite songs by not only seeing the musical scores, but also seeing pictures, letters, and colors, even if they have never played the drums at all. For learning, the software can freely select the stop, play, song section-by-segment forward (referred to as 'nodes' in music), forward, backward, and so on, to move and repeat the scores.

On the other hand, various modes can be selected according to the difficulty level for the unskilled user.

In addition, there are four modes: two-handed mode, two-handed and right-footed mode, two-handed and left-footed mode, two-handed and two-footed mode, and you can develop your skills gradually according to your level of mastery. Depending on the letter signal, the picture signal, and the drum score signal for the actual drum player can be selected and converted in real time, the hitting information is to distinguish between the strength and weakness can produce a sound close to the actual drum.

At this time, among the information displayed in colors, pictures, signals, letters, drum scores, etc. displayed on the screen in order to play the drum musical instrument, especially the letter 'kung, just, Tooth, chi-, visor, ding, tung, barrel, ting, etc., where one letter corresponds one-to-one with the sound of a drum instrument.

On the other hand, the drum sensor (1) produced for playing the drum has a relatively small area, including its volume and volume, so that several sensors are attached to the appropriate position of the garment to tap the body when practicing the actual drum performance As in the method of performing, while wearing a garment with a sensor attached to the drum intensity of the drum sensor to the desired strength and strength can also practice drum musical instrument performance.

As described above, according to the present invention, a drum sensor having a predetermined shape is connected to a server for storing sheet music information through a general-purpose personal computer and an internet network so that the drum sensor can be played like a drum with a song accompaniment. In addition, it is possible to improve the rhythmic sense of the music as well as to improve the performance of the performance while learning the drum instruments by themselves. It can be.
