Description

Technical Field

[0001] This invention relates to the field of frequency signal graphics technology, and more particularly to a frequency signal graphics device. Background Technology

[0002] Frequency signals contain information. For example, if the frequency signal is an audio signal, the content spoken by the user emitting the audio signal, the user's gender, age, emotions, and channel environment can be obtained from the audio signal. The information contained in the frequency signal can be extracted by converting the frequency signal into graphical data and then using that graphical data.

[0003] In the exemplary technology, after obtaining the frequency signal, the CPU (Central Processing Unit) performs graphics processing on the frequency signal to obtain graphics data. The CPU then inputs the graphics data to the GPU (Graphics Processing Unit) for AI (Artificial Intelligence) calculations to obtain information from the frequency signal.

[0004] Because frequency signals have a time dimension, for example, the information contained in audio is transmitted over a period of time, the CPU processes audio at intervals, for example, the CPU processes audio once every 6 seconds. This results in a large amount of graphics data, which in turn requires the GPU to process a large amount of graphics data at once, thus placing higher demands on the GPU configuration. Summary of the Invention

[0005] This invention provides a frequency signal graphics device to solve the problem that frequency signal graphics places high demands on GPUs.

[0006] On one hand, the present invention provides a graphical device for frequency signals, comprising:

[0007] The conversion module is used to convert the input frequency signal into current;

[0008] A strip-shaped object, wound with a coil, the coil being connected to the conversion module, the strip being used to emit light;

[0009] A permanent magnet is disposed opposite to the strip and is used to drive the strip to move back and forth under the action of current in the coil;

[0010] An image acquisition device is positioned relative to the strip and is used to acquire the position of the light emitted by the strip at multiple times, determine the amplitude of the frequency signal at multiple times based on the acquired positions, and generate graphic data corresponding to the frequency signal based on the amplitude and the corresponding time.

[0011] A graphics processor, connected to the image acquisition unit, is used to process the graphics data.

[0012] In one embodiment, the strip is made of a light-emitting material, and the light-collecting surface of the image collector is provided with a liquid crystal film. The liquid crystal film has multiple rows of liquid crystal molecules, and the direction of the straight line formed by each row of liquid crystal molecules is set to be the same as the moving direction of the strip. Each row of liquid crystal molecules is connected to a power source through a switch, and the switch is used to sequentially connect each row of liquid crystal molecules to the power source.

[0013] In one embodiment, the resolution of the liquid crystal film is set to be the same as the resolution of the light-collecting surface.

[0014] In one embodiment, the strip is made of a light-emitting material, and a blocking member is provided between the light-collecting surface of the image collector and the strip. The blocking member is configured to cover the light-collecting surface, and the blocking member has a plurality of through holes arranged in a row. The direction of each through hole is set to be the same as the moving direction of the strip.

[0015] In one embodiment, the cross-sectional area of ​​the through hole is set to be the same as the area of ​​the pixel of the light-collecting surface.

[0016] In one embodiment, two adjacent through holes are tangent to each other.

[0017] In one embodiment, the strip is provided with a laser emission source for emitting laser light toward the image acquisition device.

[0018] In one embodiment, the frequency signal graphics device includes a frequency divider and a plurality of frequency signal graphics components. Each frequency signal graphics component includes the conversion module, the strip, the coil, the permanent magnet, and the image acquisition unit. The frequency divider is connected to the coil in each frequency signal graphics component. The frequency divider is used to separate the frequency signal to be processed into multiple frequency bands and transmit the frequency signals of different frequency bands to the corresponding coils.

[0019] In one embodiment, the frequency signal graphical device further includes a pickup component connected to the frequency divider for picking up sound to obtain the frequency signal to be processed.

[0020] In one embodiment, the graphics processor is further configured to obtain a spectrogram of the frequency signal to be processed based on the graphics data corresponding to the frequency signals in different frequency bands.

[0021] This invention provides a frequency signal graphics device. By converting the frequency signal into current, a coil generates magnetic force under the influence of the current, causing a permanent magnet to drive a strip wound around the coil to reciprocate. The amplitude of the frequency signal at multiple moments is determined based on the position of the light emitted by the strip, captured by an image acquisition device. Graphical data corresponding to each amplitude is obtained, and this data is then input to a graphics processor for processing. In this invention, the graphics processor processes real-time frequency signal graphics data, meaning it handles less graphic data, reducing the configuration requirements of the graphics processor and lowering the cost of audio graphics.

[0038] Furthermore, the terms “comprising” and “having”, and any variations thereof, are intended to cover non-exclusive inclusion, such that a process, method, system, product, or display that includes a series of steps or units is not necessarily limited to those steps or units that are explicitly listed, but may include other steps or units that are not explicitly listed or that are inherent to such process, method, product, or display.

[0039] The present invention provides a device for graphical representation of frequency signals.

[0040] Reference Figure 1 as well as Figure 2 The frequency signal graphics device 100 includes a conversion module 110, a strip 120, a coil 130, a permanent magnet 140, an image acquisition unit 150, and a graphics processor 160.

[0041] The conversion module 110 is used to convert a frequency signal into a current. Specifically, the conversion module 110 includes an F / V converter and a V / I converter. The F / V converter first converts the frequency signal into a voltage signal, and the V / I converter then converts the voltage signal into a current signal. The frequency signal can be a high-speed, continuous frequency signal such as an audio signal.

[0042] A strip 120 is wound with a coil 130. The coil 130 is made of metal and is connected to a conversion module 110, which transmits current to the coil. The strip 120 is used to emit light.

[0043] The permanent magnet 140 is spaced apart from the strip 120, and the distance between the permanent magnet 140 and the strip 120 is small. When current is input to the coil 130, the current in the coil 130 generates magnetic force under the action of the magnetic field of the permanent magnet 140, thereby causing the permanent magnet 140 to drive the strip wound around the coil 130 to reciprocate.

[0044] In order to detect the reciprocating movement of the strip 120, the strip 120 can emit light. The image acquisition device is positioned relative to the strip 120 so that the image acquisition device 150 can acquire the position of the light emitted by the strip 120, and then determine the moving distance of the strip 120 by the acquired position of the light.

[0045] In one example, the light-collecting surface of the image acquisition device 150 is set to be parallel to the plane containing the moving direction of the strip 120, so that the image acquisition device 150 can accurately acquire the moving distance of the strip 120. The image acquisition device 150 may be an image sensor.

[0046] The magnitude of the current is related to the amplitude of the frequency signal; the larger the amplitude of the frequency signal, the larger the current, and the greater the distance the strip moves. Therefore, the moving distance of the strip 120 can be converted into the amplitude of the frequency signal. The image acquisition unit 150 acquires the position of the light emitted by the strip 120 at intervals to determine the time corresponding to the amplitude of the frequency signal. Then, through each amplitude and the time corresponding to the amplitude, the image acquisition unit 150 can generate graphic data corresponding to the frequency signal. The graphic data can be a waveform diagram with time on the horizontal axis and amplitude on the vertical axis.

[0047] The graphics processor 160 is connected to the image acquisition unit 150. The image acquisition unit 150 transmits image data to the graphics processor 160. The graphics processor 160 analyzes the image data through AI operations to obtain information contained in the frequency signal. The AI ​​operation method is based on deep learning algorithms for images.

[0048] In this embodiment, the real-time frequency signal is converted into graphic data using the photoelectric conversion principle, and the graphic data is then sent to the graphics processor for processing. That is, the graphics processor processes the graphic data frame by frame. Compared to the prior art where the CPU inputs graphic data of a frequency signal over a period of time into the graphics processor for processing, the graphics processor in the frequency signal graphics device provided in this embodiment processes less data, reducing the configuration requirements of the graphics processor and thus lowering the cost of frequency signal graphics.

[0049] In this embodiment, by converting the frequency signal into current, the coil generates magnetic force under the action of the current, causing a permanent magnet to drive a strip of material wound around the coil to move back and forth. The amplitude of the frequency signal at multiple moments is determined based on the position of the light emitted by the strip, which is collected by an image acquisition device. Graphical data corresponding to the frequency signal is obtained through each amplitude, and then the graphic data is input to a graphics processor for processing. In this invention, the graphics processor processes graphic data of real-time frequency signals, that is, the amount of graphic data processed by the graphics processor is relatively small, which reduces the configuration requirements of the graphics processor and reduces the cost of audio graphics.

[0050] Reference Figure 3 The material of the strip 120 is a light-emitting material, for example, the strip 120 can be a glow stick.

[0051] An image acquisition device 150 has a liquid crystal film 151 on its light-collecting surface. The liquid crystal film 151 has multiple rows of liquid crystal molecules 152, and the direction of the straight line formed by each row of liquid crystal molecules 152 is set to be the same as the moving direction of the strip 120. Each row of liquid crystal molecules 152 is connected to a power supply (not shown) via a switch (not labeled), which sequentially connects each row of liquid crystal molecules to the power supply. The sequential connection of each row of liquid crystal molecules to the power supply can be achieved using a shift register. Specifically, electrodes are provided at both ends of each row of liquid crystal molecules 152, allowing each row of liquid crystal molecules 152 to be connected to the switch via the electrodes.

[0052] When a row of liquid crystal molecules 152 is powered on, the liquid crystal molecules 152 allow vertical light to pass through the liquid crystal film 151, thereby enabling the image collector 150 to collect vertical light. The light-collecting surface of the image collector 150 can be divided into multiple pixels. When light shines on an area of ​​the light-collecting surface, the pixels in that area are illuminated.

[0053] In this embodiment, the sampling frequency is set by switching the frequency of liquid crystal molecules using a switch. For example, if the switch switches the liquid crystal molecules that are connected to the power supply every 1 / 60th of a second, the sampling frequency is 60Hz. In the first 1 / 60th of a second, the first row of liquid crystal molecules 152 is connected to the power supply, and a pixel in one area of ​​the image acquisition unit 132 is lit; in the second 1 / 60th of a second, the second row of liquid crystal molecules 152 is connected to the power supply, and a pixel in the second area of ​​the image acquisition unit 132 is lit. In this way, the lit areas on the image acquisition unit 132 can be determined. Connecting the lit areas yields a waveform diagram with time on the horizontal axis and amplitude on the vertical axis, i.e., graphic data. Specifically, refer to... Figure 4 , Figure 3 This refers to the image data acquired by the image acquisition device 150 based on the conduction of liquid crystal molecules on the liquid crystal film 151.

[0054] Furthermore, the resolution of the liquid crystal film 151 is set to be the same as the resolution of the light-collecting surface. For example, if the resolution of the image collector is 1920*1024, then the resolution of the liquid crystal film 151 is also 1920*1024. If the resolution of the liquid crystal film 151 is the same as the resolution of the light-collecting surface, then the area illuminated on the image collector 150 each time is a pixel, thereby accurately generating graphic data from each illuminated pixel.

[0055] If the illuminated area consists of multiple pixels, the image acquisition unit 150 needs to determine the center pixel of the illuminated area, which requires a significant amount of computing resources. By setting the resolution of the liquid crystal film 151 to be the same as the resolution of the light-collecting surface, excessive computing resources can be avoided by the image acquisition unit 150, thus reducing the configuration requirements for the image acquisition unit 150.

[0056] In this embodiment, the material of the strip 120 is a light-emitting material. A liquid crystal film is provided on the light-collecting surface of the image collector 150. By deflecting the liquid crystal molecules in the liquid crystal film, the image collector 150 collects light in a fixed direction, instead of collecting light emitted from the strip 120 in all directions. Thus, the graphic data corresponding to the frequency signal is accurately obtained by the position of the light in the fixed direction.

[0057] Reference Figure 5 as well as Figure 6 The strip 120 is made of a light-emitting material and emits light in 360 degrees. All pixels on the light-collecting surface of the image collector 150 will be lit up. In other words, the image collector 150 cannot determine the moving distance of the strip 120 based on the collected light.

[0058] To address this, a shielding member 170 is provided between the light-collecting surface of the image collector 150 and the strip 120, with the shielding member 170 designed to cover the light-collecting surface. The shielding member 170 has a row of through holes 171, and the direction of each through hole 171 is set to be the same as the moving direction of the strip 120.

[0059] The through-hole 171 on the blocking member 170 ensures that the image acquisition device 150 can only acquire the light emitted by the strip 120 transmitted through the through-hole 171. Furthermore, the image acquisition device 150 is configured to acquire light at a set frequency; for example, it may start acquiring light every 1 / 60th of a second. Therefore, the image acquisition device 150 can obtain the illuminated areas and their corresponding acquisition times. The positions of the illuminated areas can be converted into the amplitude of the frequency signal during the acquisition time, thus generating a graphic region corresponding to the frequency signal based on the positions of each illuminated area and its corresponding acquisition time.

[0060] Furthermore, the cross-sectional area of ​​the through hole is set to be the same as the area of ​​the pixel on the light-collecting surface, that is, the area lit up on the light-collecting surface is one pixel, thereby accurately generating graphic data.

[0061] Furthermore, when the distance between two adjacent through holes 171 is large, meaning there is an obstruction area between them, if the strip 120 moves above the obstruction area, the image acquisition unit 150 will be unable to capture the distance the strip 120 has moved at that moment. To address this, adjacent through holes 171 are configured to be tangent, thus eliminating the obstruction area between them and allowing the image acquisition unit 150 to capture the distance the strip 120 has moved at any given time.

[0062] In this embodiment, the strip 120 is made of a light-emitting material. By setting a blocking member 170 between the light-collecting surface of the image collector 150 and the strip 120, the image collector 150 collects the light transmitted through the through hole in the blocking member 170, but does not collect the light emitted from all directions by the strip 120. Thus, the graphic data corresponding to the frequency signal is accurately obtained through the position of the light transmitted through the through hole.

[0063] In one embodiment, the shielding member 170 may be provided with multiple rows of through holes, and the direction of the arrangement of the through holes in each row is set to be the same as the moving direction of the strip 120.

[0064] Furthermore, the image acquisition unit 150 is configured with a sampling frequency. For example, it may start collecting light every 1 / 60th of a second, and the number of rows of vias in which the light is collected varies each time. For instance, in the first 1 / 60th of a second, the image acquisition unit 150 identifies the illuminated area under the first row of vias; in the second 1 / 60th of a second, it identifies the illuminated area under the second row of vias; in the third 1 / 60th of a second, it identifies the illuminated area under the third row of vias; and in the fourth 1 / 60th of a second, it identifies the illuminated area under the fourth row of vias. In this way, multiple illuminated areas can be identified, and connecting these illuminated areas yields the image region.

[0065] Furthermore, when the distance between two adjacent through holes is large, that is, there is an obstruction area between the two adjacent through holes, if the strip 120 moves above the obstruction area, the image acquisition device 150 will not be able to acquire the moving distance of the strip 120 at this moment.

[0066] In this regard, two adjacent through holes in a row are set to be tangent, and two adjacent through holes in a column are also set to be tangent, so that there is no obstruction area between adjacent through holes 171, which means that the image acquisition device 150 can acquire the moving distance of the strip 120 at any time.

[0067] In addition, the cross-sectional area of ​​the through hole is set to be the same as the area of ​​the pixel on the light-collecting surface, that is, the area lit on the light-collecting surface is one pixel, thereby accurately generating graphic data.

[0068] In this embodiment, the strip 120 is made of a light-emitting material. By setting a shielding member 170 between the light-collecting surface of the image collector 150 and the strip 120, and the shielding member 170 is provided with multiple rows of through holes, the image collector 150 collects the light transmitted through the through holes in the shielding member 170, but does not collect the light emitted from all directions by the strip 120. Thus, the position of the light transmitted through the through holes accurately obtains the graphic data corresponding to the frequency signal.

[0069] In one embodiment, a laser emission source is provided on the strip 120, and a laser beam in a fixed direction is sent to the image acquisition device through the laser emission source.

[0070] In addition, the image acquisition unit 150 sets the acquisition frequency. For example, the image acquisition unit 150 is activated to acquire laser light every 1 / 60 of a second. Thus, the image acquisition unit 150 can obtain the illuminated area and the corresponding acquisition time. The position corresponding to the illuminated area can be converted into the amplitude of the frequency signal during the acquisition time. Therefore, the graphic area corresponding to the frequency signal can be generated by the position of each illuminated area and the corresponding acquisition time.

[0071] In existing technologies, frequency signals have high-frequency and low-frequency bands. For example, a frequency signal is an audio signal, which has loud and soft signals, and these signals can occur simultaneously. When processing audio signals, the soft signals are treated as redundant signals and removed. However, the soft signals may contain some crucial information, and removing them can result in the loss of this crucial information.

[0072] In this regard, refer to Figure 7 The frequency signal graphics device 100 also includes a frequency divider 180 and multiple frequency signal graphics components 190. Each frequency signal graphics component 190 includes a conversion module 110, a strip 120, a coil 130, a permanent magnet 140, and an image acquisition device 150. The connection relationships of the strip, coil, and image acquisition device in each frequency signal graphics component are as described above and will not be repeated here.

[0073] Frequency divider 180 separates the frequency signal to be processed to obtain frequency signals of multiple frequency bands. Frequency divider 180 is connected to coil 130 in the graphic component 190 of each frequency signal, so frequency divider 180 can transmit frequency signals of different frequency bands to the corresponding coil 130.

[0074] The number of frequency signal graphics components 190 is related to the resolution of the image acquisition unit 150. For example, if the resolution of the image acquisition unit 150 is 1920*1024, then the height of the waveform acquired by the image acquisition unit 150 is 1024. If the sampling rate is 16-bit, then 1024 / 16 = 64 frequency bands can be separated, meaning 64 frequency signal graphics components 190 can be set. The graphics processor 160 can obtain the spectrogram of the frequency signal to be processed based on the graphic data corresponding to the frequency signals in different frequency bands.

[0075] Furthermore, the frequency signal graphical device 100 also includes a sound pickup component 181. The sound pickup component can be a microphone. The sound pickup component 181 is connected to the frequency divider 180. After picking up the sound, the sound pickup component 181 obtains the frequency signal to be processed, and then transmits the frequency signal to be processed to the frequency divider 180 for frequency band separation.

[0076] In this embodiment, the frequency signal to be processed is separated into multiple frequency bands, so that the frequency signals of each frequency band can be converted into graphic data, avoiding the omission of key information.
