Description

Technical Field

[0001] The present invention relates to a device, and more particularly to a computer device and an auditory sensation correction method.

Background Art

[0002] Currently, most of the sound output holes of the built-in speakers of general notebook computers are installed at the bottom of the computer, and the audio is played in a downward sound output manner and transmitted to the user's ears through reflection on the placement plane. However, due to differences in the material of the placement plane (i.e., differences in the degree of hardness), the sound quality of the reflected audio passing through the reflection on the placement plane also changes. In particular, when a notebook computer is placed on a soft object, the reflection situation of high-frequency sounds does not meet expectations, so a large amount of high-frequency sounds are absorbed by the soft desktop. Thus, abnormal phenomena appear in the overall acoustic performance of the built-in speakers, such as the auditory sensation being slightly muffled or some high-frequency sounds being significantly attenuated.

Problems to be Solved by the Invention

[0004] The computer device of the present invention includes a sensor, an audio player, and a processor. The audio player faces the direction of the placement plane. The processor is coupled to the sensor and the audio player. The processor obtains physical parameters through the sensor and determines the material type of the placement plane based on the physical parameters. The processor adjusts the equalizer of the audio player based on the material type and causes the audio player to perform audio playback based on the adjusted equalizer.

[0005] The auditory correction method of the present invention includes the steps of acquiring physical parameters through a sensor, determining the material type of the placement plane based on the physical parameters, adjusting the equalizer of the audio player based on the material type, and causing the audio player to perform audio playback toward the placement plane based on the adjusted equalizer. [Effects of the Invention]

[0009] To facilitate understanding of the present invention, the following examples illustrate how this disclosure can be reliably implemented. Furthermore, wherever possible, elements / components / steps using the same reference numerals in the drawings and embodiments may represent the same or similar components.

[0010] Figure 1 is a schematic circuit diagram of a computer device according to one embodiment of the present invention. Referring to Figure 1, the computer device 100 includes a processor 110, a sensor 120, and an audio player 130. The processor 110 is coupled to the sensor 120 and the audio player 130. In this embodiment, the processor 110 can detect the material type of the placement plane at the current placement position of the computer device 100 through the sensor 120, and can adjust the equalizer of the audio player 130 accordingly based on the material type.

[0011] In this embodiment, the processor 110 may be, for example, a Central Processing Unit (CPU), or other programmable general-purpose or dedicated microprocessor, Digital Signal Processor (DSP), Application-Specific Integrated Circuit (ASIC), Programmable Logic Device (PLD), or other similar arithmetic circuits or combinations thereof. In this embodiment, the computer device 100 may further include a storage unit. The storage unit may include, for example, any form of hard disk drive (HDD), solid state disk (SSD), non-volatile memory (NVM), dynamic random access memory (DRAM), or static random access memory (SRAM). The storage unit can be used to store the relevant data, arithmetic modules, and equalizer-related programs of the present invention, and can be read and executed by the processor 110.

[0012] Figure 2 is a schematic diagram of a computer device according to one embodiment of the present invention. Referring to Figures 1 and 2, in this embodiment, the computer device 100 can be implemented as a notebook computer as shown in Figure 2. The computer device 100 may include a first body 101, a second body 102, and a rotatable member 103, wherein the second body 102 is connected to the first body 101 by the rotatable member 103, and the bottom surface of the second body 102 faces the direction of the arrangement plane S1. Audio players 130 can be installed on both sides of the bottom surface of the second body 102, but the present invention is not limited thereto. In this embodiment, the audio player 130 can perform audio playback from the bottom surface of the second body 102 toward the arrangement plane S1.

[0013] In this embodiment, the computer device 100 may further include a display 140 and a keyboard module 150. The display 140 may be installed on a display area on one surface of the first body 101. The keyboard module 150 may be installed on the upper surface of the second body 102. In this embodiment, the sensor 120 may be an audio receiver (or microphone) and may be installed, for example, in the area surrounding the display 140 on the surface of the first body 101 (for example, above the display 140), but the present invention is not limited thereto. In one embodiment, the sensor 120 may be a pressure sensor or a light sensor.

[0014] Figure 3 is a flowchart of an auditory correction method according to one embodiment of the present invention. Referring to Figures 1 to 3, the computer device 100 can perform the following steps S310 to S330. In step S310, the processor 110 can acquire physical parameters through the sensor 120. In step S320, the processor 110 can determine the material type of the placement plane S1 based on the physical parameters. In step S330, the processor 110 adjusts the equalizer of the audio player 130 based on the material type and causes the audio player 130 to perform audio playback toward the placement plane S1 based on the adjusted equalizer.

[0015] Specifically, the sensor 120 may be an audio receiver, and the physical parameter may be audio amplitude. The processor 110 can first play the measurement audio through the audio player 130, and the measurement audio is reflected through the placement plane S1, so that the processor 110 can receive the reflected audio corresponding to the measurement audio through the audio receiver. The processor 110 can analyze the reflected audio and determine the audio amplitude of the reflected audio. The processor 110 can determine the material type of the placement plane S1 based on the audio amplitude.

[0016] In this embodiment, the measured audio may be formed by multiple sine waves of multiple fixed frequencies. Furthermore, the multiple fixed frequencies may be frequencies belonging to the mid-to-high frequency band, for example, between 4,000 Hz (kHz) and 8,000 Hz (kHz). In this embodiment, since the placement planes of different material types have different degrees of absorption of the acoustic signal, the processor 110 can determine the material type of the placement plane S1 by determining whether the audio amplitude of the multiple reflected audio corresponding to different frequencies is greater than or less than the corresponding multiple amplitude thresholds. In one embodiment, the processor 110 can also accurately determine the material type of the placement plane S1 by searching for the audio curve of the material that best approximates it through the magnitude of the audio amplitude of the multiple reflected audio corresponding to different frequencies. In one embodiment, the processor 110 can also identify the audio curve using a trained machine learning model.

[0017] As an example of a signal waveform of a specific frequency, Figure 4A shows a signal waveform diagram of measurement audio corresponding to a fixed frequency in one embodiment of the present invention. The measurement audio may have a signal waveform corresponding to one fixed frequency, for example, as shown in Figure 4A. For example, taking the case where the placement plane S1 is a wooden desktop, the processor 110 first plays measurement audio having a signal waveform as shown in Figure 4A through the audio player 130, and as the measurement audio is reflected through the placement plane S1, the processor 110 can receive reflected audio (reflected from the placement plane S1) corresponding to the measurement audio through the sensor 120. In contrast, since the degree of acoustic reflection of a wooden desktop is good, the reflected audio has lower loss. As shown in Figure 4B, Figure 4B shows a signal waveform diagram of reflected audio in one embodiment of the present invention. The reflected audio may have a signal waveform diagram of reflected audio corresponding to the same fixed frequency, for example, as shown in Figure 4B, and the audio amplitude is 11 dB. In other words, in one embodiment, the processor 110 can determine that the placement plane S1 is a wooden desktop by determining whether the reflected audio has an audio amplitude corresponding to the fixed frequency that is greater than a first default amplitude threshold, and the first default amplitude threshold may be, for example, 10 dB.

[0018] As another example, if the placement plane S1 is a foam cushion, the processor 110 first plays a measurement audio having a signal waveform as shown in Figure 4A through the audio player 130, and as the measurement audio is reflected through the placement plane S1, the processor 110 can receive the reflected audio (reflected from the placement plane S1) corresponding to the measurement audio through the sensor 120. In contrast, since the degree of acoustic reflection of the foam cushion is inferior, the reflected audio has a higher loss. As shown in Figure 4C, Figure 4C is a signal waveform diagram of reflected audio in another embodiment of the present invention. The reflected audio may have a signal waveform diagram of reflected audio corresponding to the same fixed frequency as shown in Figure 4C, for example, and the audio amplitude is 3dB. In other words, in one embodiment, the processor 110 can determine that the placement plane S1 is a foam cushion by determining whether the audio amplitude of the reflected audio corresponding to the fixed frequency is less than a second default amplitude threshold, and the second default amplitude threshold may be, for example, 4dB.

[0019] After the processor 110 confirms the material type of the placement plane S1, the processor 110 can read the corresponding default adjustment record file and automatically adjust the equalizer of the audio player 130. As an example, as shown in Figure 5, Figure 5 is a schematic diagram of an audio curve in one embodiment of the present invention. Taking the case where the placement plane S1 is a foam cushion as an example, the audio curve 502 generated by audio playback performed by the audio player based on an unadjusted equalizer will differ from the standard audio curve 501, where the standard audio curve 501 may be generated, for example, by placing a computer device 100 on a specific desktop in an anechoic chamber, playing pink noise through the audio player 130, and receiving reflected audio corresponding to the pink noise through an audio receiver. The processor 110 can adjust the equalizer of the audio player 130 based on the difference between the standard audio curve 501 and the audio curve 502. In one embodiment, the specific desktop may be a wooden desktop, but the present invention is not limited thereto. Therefore, by adjusting the mid-to-high frequency portion of the equalizer of the audio player 130, the processor 110 can make the perceived sound of the audio played by the audio player 130 after equalizer adjustment closer to the effect of placing the computer equipment 100 on a wooden desktop.

[0020] In this way, the audio curve generated by the audio playback executed by the audio player 130 based on the adjusted equalizer can be made closer to the standard audio curve 501 compared to the audio curve 502 generated by the audio playback executed by the audio player 130 based on the unadjusted equalizer. In other words, when the user places the computer device 100 on the foam cushion and executes computer operations (i.e., executes audio playback), the processor 110 determines that the computer device 100 is placed on the foam cushion through the reflected audio, and by automatically adjusting the equalizer of the audio player 130, the user can make the listening feeling of the audio played by the audio player 130 closer to the effect of placing the computer device 100 on a wooden desktop.

[0021] However, in one embodiment, the sensor 120 may be a pressure sensor and can be installed on the bottom surface of the second body 102. In contrast, the physical parameter obtained by the sensor 120 may be a pressure value. The processor 110 can determine the material type of the placement plane S1 based on the pressure value. For example, taking a wooden desktop as an example, since the hardness of the wooden desktop is relatively high, the pressure value obtained by the sensor 120 may be relatively high. The processor 110 can determine that the placement plane S1 is a wooden desktop by, for example, determining whether the pressure value obtained by the sensor 120 exceeds a first pressure threshold. In contrast, taking a foam cushion as an example, since the hardness of the foam cushion is relatively low, the pressure value obtained by the sensor 120 may be relatively low. The processor 110 can determine that the placement plane S1 is a foam cushion by, for example, determining whether the pressure value obtained by the sensor 120 is less than a second pressure threshold. The first pressure threshold may exceed or be equal to the second pressure threshold.

[0022] In another embodiment, the sensor 120 may be a displacement sensor and can be installed on the bottom surface of the second body 102. In contrast, the physical parameter obtained by the sensor 120 may be a displacement value. The processor 110 can determine the material type of the placement plane S1 based on the displacement value. For example, taking a wooden desktop as an example, since the hardness of the wooden desktop is relatively high, the displacement value obtained by the sensor 120 may be relatively high. The processor 110 can determine that the placement plane S1 is a wooden desktop by determining, for example, whether the displacement value obtained by the sensor 120 exceeds a first displacement threshold value. In contrast, taking a foam cushion as an example, since the hardness of the foam cushion is relatively low, the displacement value obtained by the sensor 120 may be relatively low. The processor 110 can determine that the placement plane S1 is a foam cushion by determining, for example, whether the displacement value obtained by the sensor 120 is less than a second displacement threshold value. The first displacement threshold value may exceed or be equal to the second displacement threshold value.

[0023] In another embodiment, the sensor 120 may include a light-emitting element and a light sensor, and can be installed on the bottom surface of the second body 102 respectively. In contrast, the physical parameter obtained by the light sensor may be a wavelength parameter. The light-emitting element can emit detection light in the direction of the placement plane S1, and the light sensor can receive the reflected light reflected by the placement plane S1 from the detection light. The processor 110 can determine the material type of the placement plane S1 based on whether the wavelength parameter of the reflected light matches the specific wavelength parameter of a specific material type.

[0024] As described above, the computer device and auditory correction method of the present invention can effectively and automatically determine the material type of the plane on which the computer device is currently positioned through audio detection, pressure detection, displacement detection, or optical detection, and can appropriately adjust the equalizer of the audio player based on the material type. Therefore, the computer device and auditory correction method of the present invention can achieve good audio reproduction effects in response to different plane materials.
