DETAILED DESCRIPTION OF THE INVENTION

The aforementioned and further advantages and features of the present invention will be understood by reference to the description of the preferred embodiment in conjunction with the accompanying drawings where the components are illustrated based on a proportion for explanation but not subject to the actual component proportion.

Referring to Fig. 1 to Fig. 3, a melody concretization identification system 100 is disclosed, comprising a database 10 and a calculation module 20.

The database 10 stores a plurality of audio signal data 11 and a concretization command 12 corresponding to each audio signal data 11. The audio signal data 11 comprises an amplitude parameter 111 and a time parameter 112. The amplitude parameter 111 and the time parameter 112 of the audio signal data 11 are integrated into a coordinate diagram 13, and the concretization command 12 is reflected on the coordinate diagram 13. More particularly, referring to Fig. 3, the transverse axis 131 of the coordinate diagram 13 is formed of the time parameter 112 of each audio signal data 11, and the longitudinal axis 132 is formed of the amplitude parameter 111 of each audio signal data 11. In other words, each audio signal data 11 is a value of the time parameter 112 corresponding to the amplitude parameter 111. Therein, the time parameter 112 is allowed to be 0.1 seconds, 0.5 seconds, 1 second, or other time unit, and the concretization command 12 is reflected in the coordinate diagram 13 in accordance with a matched amplitude. Further, referring to Fig. 3, the concretization command 12 is able to be applied for controlling the displaying light colors and patterns. When the concretization command 12 is applied for controlling the displaying lights, the concretization command 12 is a hexadecimal code, wherein when the concretization command 12 is a hexadecimal code, each concretization command 12 varies over time, i.e. corresponding to the transverse axis 131 of the coordinate diagram 13. When the concretization command 12 is applied for controlling the displaying patterns, each concretization command 12 varies over time and the amplitudes, i.e. corresponding to the transverse axis 131 and the longitudinal axis 132 of the coordinate diagram 13.

The calculation module 20 is coupled with the database 10 and the target device 1. The calculation module 20 comprises an input unit 21 for receiving a music which is played in an external environment or inputted through a signal. The input unit 21 is a microphone and a communication port coupled with a signal wire, wherein the microphone is applied for receiving the music 2 played in an external environment, and the communication port is applied for signally receiving the music The calculation module 20 comprises an analysis unit 22, which analyzes the music 2 received through the input unit 21 to produce a plurality of period information, wherein the period information comprises a frequency, amplitude, and time. More particularly, when the music 2 enters the analysis unit 22, the analysis unit 22 locates the frequency and amplitude of the music 2 at intervals. In the embodiment, the analysis unit 22 generates a period information over a 4-tempo period. The number of tempos of each period in the present invention is not limited to the example herein and allowed to be adjusted according to different demands.

The calculation module 20 further comprises a match unit 23 and an output unit 24. The match unit 23 is applied for matching each period information process by the analysis unit 22 with each audio signal data 11 in the database 10, so as to acquire the concretization command 12 matching each period information. In other words, the match unit 23 reflects each period information and time point in the coordinate diagram 13, thereby acquiring the matching concretization command 12. For example, if the amplitude of the period information is 0.5, the time is 1.9 seconds, and therefore, in the coordinate diagram 13, the color is yellow and the pattern is a suspicious emotion. As a result, the match unit 23 acquires the concretization command 12 of an ffff00 color code and a suspicious emotion pattern. The output unit 24 is connected with the target device 1 20 through a wired connection. The output unit 24 outputs the -8 -acquired concretization command 12 and the corresponding music 2 to the target device 1, so that the target device 1 produces the visual performance corresponding to the music 2, as shown in Fig. 1. In the embodiment, the calculation module 20 and the database 10 are disposed in the target device 1. The output unit 20 has a speaker. When the input unit 21 receives the signal of the music 2 through the communication port, the speaker simultaneously plays out the music 2 when the concretization command 12 is outputted to the target device 1, whereby the target device 1 produces the visual performance corresponding to the music 2.

In addition, the target device 1 is allowed to be a lamp or a robot. The target device 1 comprises a plurality of light members each having a color code. Therein, the color code is an ROB value coded in 24 bits per pixel (bpp) through the RBG color model. For example when the hexadecimal code of the concretization 12 is ffff00, the corresponding color code is presented as a yellow color on the light member.

Furthermore, when the target device 1 is a robot, the target 20 device 1 also comprises a display interface. When the concretization command 12 is a pattern, the display interface displays the concretization command 12 as an expression pattern.

Additionally, the calculation module 20 comprises a 5 storage unit 25 for storing the concretization command 12 matching the music 2. Therefore, when the match unit 23 processes a music 2 each time, the concretization command 12 matching the processed music 2 is stored in the storage unit 25. When the input unit 21 receives the identical music 2 next time, 10 the analyzing and processing steps are omitted, and the concretization command 12 corresponding to the music 2 can be directly performed on the target device 1, whereby the calculation burden of the calculation module 20 is lowered.

Thus, when the input unit 21 of the melody concretization identification system 100 receives the music which is signally inputted through external playing environment, the input unit 21 transmits the music 2 to the analysis unit 22 at the same time, and the analysis unit 22 process the music 2 into the period information. Then, the match unit 23 matches the period information with the database 10, and the output unit 24 outputs -10 -the concretization command 12 and the music 2 to the target device 1, whereby the target device produces the visual performance according to the concretization command 12 immediately generated from the music 2.

Therefore, when the music 2 is played, the melody concretization identification system 100 integrates the music 2 with visual effects, so as to produce visual performance on the target device 1, thereby achieving a variety of visual effects through an active controlling method.

Further, the audio signal data 11 and the concretization command 12 are integrated in the coordinate diagram 13, so that the data storage volume is lowered. Also, the match unit 23 reflects the period information of the music 2 on the coordinate diagram 13, so that the matching concretization command 12 is easily and efficiently located, thereby lowering the calculation time and process of the calculation module 20, providing a music-based real-time visual performance.

Although particular embodiments of the invention have been described in detail for purposes of illustration, various 20 modifications and enhancements may be made without departing from the spirit and scope of the invention. Accordingly, the invention is not to be limited except as by the appended claims.
