DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENT

[0012] Referring to FIGS. 1-3, a rhythm diagram of the present invention, a flow chart of the present invention, a pitch range diagram of the present invention are shown and a schematic diagram of the complex pitch range of the present invention during action performance are shown.

[0013] The method of generating actions following the rhythm of music in accordance with the present invention comprises the steps of: [0014] (a) Use an electronic device to classify the sound signals from plural musical instruments (such as guitars, drums, bass, piano, cymbals or other musical instruments) into a complex pitch range. [0015] (b) The electronic device then selects at least one pitch range according to the significance of the sound, and then performs Fourier series conversion on the sound signal of the at least one pitch range to obtain at least one rhythm diagram of the at least one pitch range where the rhythm diagram represents the intensity change of at least one frequency in the sound signal over time. [0016] (c) The electronic device performs a rhythm change point 1 capture action on the at least one rhythm diagram, then executes no action if the intensity in the rhythm diagram continues to increase with time, or regards the point as the rhythm change point 1 if the intensity changes from an increase to a decrease and at this time, the electronic device transmits an action signal to an action device. [0017] (d) After received the action signal, the action device executes the corresponding action according to the action signal to complete the use of the present invention.

[0018] The above-mentioned electronic device can be a desktop computer, notebook computer, tablet computer, smart phone, personal digital assistant or other electronic devices with. computing functions.

[0019] Furthermore, the complex pitch range in the above step (a) includes the subwoofer range 2, the low range 3, the mid-range 4, and the high range 5. The frequency range of the subwoofer range 2 is between 0˜140 Hz, the frequency range of the low range 3 is between 140˜400 Hz, the frequency range of the mid-range 4 is between 400˜800 Hz, the frequency range of the high range 5 is between 800˜18000 Hz.

[0020] In the above step (b), the significance of the sound can be the frequency value, the sound intensity value or other elements of the music composition.

[0021] In the above step(b), the electronic device first selects the subwoofer range 2 and the high range 5, and then selects the low range 3 or the mid-range 4 if both the subwoofer range 2 and the high range 5 have no rhythm change point 1

[0022] The electronic device in the above step (c) preferably can transmit the action signal to the action device through a transmission line, but in practical applications, it can also use wireless transmission methods (such as: Wi-Fi, Bluetooth or infrared, etc.) to transmit the action signal to the action device.

[0023] Furthermore, the action device in the above step (c) can be a light-emitting device (such as: LED), a water spray device, a fire spray device, a dry ice spray device, a pyrotechnic device or other action devices that can perform actions in conjunction with music broadcasting, and thus, you can use the light-emitting device to match the rhythm of the light change, simulate the water dance change, simulate the torch change or any scene lighting special effect change, or you can use a water spray device, a fire spray device, a dry ice spray device, a pyrotechnic device or other action devices to spit fire, spray water, spray dry ice, set off fireworks or other actions. However, there are many types of related action devices, which can receive action signals to perform actions in accordance with the rhythm of the music. Therefore, all structures that can achieve the aforementioned effects should be covered by the present invention. Such simple modifications and equivalent structural changes should be included in the scope of the patent of the present invention for the same reason.

[0024] When the present invention is actually used, the electronic device classifies the sound signals from plural musical instruments into a complex pitch range (e.g.: subwoofer range 2 between 0˜140 Hz, low range 3 between 140˜400 Hz, mid-range 4 between 400˜800 Hz, and high range 5 between 800˜18000 Hz). Then, the electronic device selects at least one pitch range (for example, the subwoofer range 2 and the high range 5) according to the significance of the sound (such as: the frequency value), and then the electronic device performs Fourier series conversion on the sound signals of at least one pitch range to obtain at least one rhythm diagram of the complex pitch range, and then, the electronic device performs a rhythm. change point 1 capture action on the at least one rhythm diagram. If the intensity in the rhythm diagram continues to increase with time, the electronic device executes no action, if the intensity changes from an increase to a decrease and at this time, the point is regarded as the rhythm change point 1 (at the apex of the wave front in the diagram). At this time, the electronic device transmits an action signal to an action device. After received the action signal, the action device executes the corresponding action according to the action signal. That is to say, the action device takes the key instruments in the music as the main rhythm, and performs actions according to the main rhythm, so that when the audience listens to the music, they can see or feel the action following the rhythm of the music, which can enhance the overall performance and appreciation of the music,

[0025] The above is only the preferred embodiment of the present invention, and it does not limit the patent scope of the present invention. Therefore, all simple modifications and equivalent structural changes made by using the description and schematic content of the present invention should be included within the scope of the patent of the present invention.

[0026] In summary, the method of generating actions following the rhythm of music of the present invention can indeed achieve its efficacy and purpose in practical applications, so the present invention is a research and development with excellent practicability, and it meets the requirements of an invention patent application.
