[0016] Figure 2 This is a circuit block diagram of a sound supply system and its sound adjustment device according to another embodiment of the present invention.

[0017] Figure 3 This is a circuit block diagram of a sound adjustment device according to another embodiment of the present invention. Detailed Implementation

[0018] Reference will now be made in detail to exemplary embodiments of the invention, examples of which are illustrated in the accompanying drawings. Wherever possible, the same element references are used in the drawings and description to denote the same or similar parts.

[0019] Figure 1 This is a circuit block diagram of a sound supply system and its sound adjustment device according to an embodiment of the present invention. Please refer to... Figure 1 The sound supply system 50 of this embodiment includes a physiological information sensor 52, a processor 54, and a sound adjustment device 100 according to an embodiment of the present invention. The physiological information sensor 52 is used to sense a user's physiological information. The physiological information measured by the physiological information sensor 52 may include one or more physiological information such as heart rate, blood pressure, sweating level, and video. The physiological information sensor 52 may be worn normally on the user's body or be a specialized medical device.

[0020] The processor 54 is connected to the physiological information sensor 52 to receive physiological information and generate physiological state information based on the physiological information. The physiological state information may indicate, for example, whether the user's physiological state is awake, about to fall asleep, or currently asleep, but the present invention is not limited thereto.

[0021] The sound adjustment device 100 of this embodiment includes an audio receiving component 110, a physiological state information receiving component 120, a frequency adjuster 130, and an output port 140. The audio receiving component 110 receives audio. The physiological state information receiving component 120 receives physiological state information. The frequency adjuster 130 is signal-connected to the audio receiving component 110 and the physiological state information receiving component 120, and is used to adjust the audio to a left-ear audio and a right-ear audio. A first frequency of the left-ear audio and a second frequency of the right-ear audio have a frequency difference. This frequency difference is determined by the frequency adjuster 130 based on the physiological state information. That is, depending on the received physiological state information, the frequency adjuster 130 can adjust the audio in different ways, making the frequency difference between the first frequency of the left-ear audio and the second frequency of the right-ear audio different.

[0022] Output port 140 is used to connect to an earphone 10, outputting left-ear audio to a left-ear speaker 12 of the earphone 10, and right-ear audio to a right-ear speaker 14 of the earphone 10. The left-ear speaker 12 and right-ear speaker 14 transmit the left-ear and right-ear audio to the user respectively using sound waves. In this way, there will be a frequency difference between the sound waves received by the user's left ear and the sound waves received by their right ear, and this difference in frequency will result in different sensations for the user. Output port 140 can be a wired connector such as a 3.5φ audio connector or a USB Type-C connector, or a wireless signal transmitter such as Bluetooth.

[0023] In the sound adjustment device and sound supply system of this embodiment, the frequency adjuster determines the frequency difference based on physiological state information, so that the user can obtain the corresponding effect when listening to sound waves according to their own physiological state.

[0024] Brainwaves refer to the electrical oscillations produced by the activity of nerve cells in the human brain; they can also be described as the rhythm of brain cell activity. The human brain generates brainwaves at all times. Classified by frequency, brainwaves include at least beta waves, alpha waves, theta waves, delta waves, and gamma waves. Generally, brainwaves during stage III of non-rapid eye movement (NREM) sleep are typically delta waves (frequency between 0.5 Hz and 4 Hz); brainwaves during deep sleep (dreaming), deep meditation, or intensely focused states are typically theta waves (frequency between 4 Hz and 8 Hz); brainwaves during the pre-sleep state of mental fog, gradually blurring consciousness, sudden flashes of insight, and relaxed yet focused attention are typically alpha waves; and brainwaves during a relaxed but focused state, processing previously received information, are typically beta waves. However, research has also found that when the brain is induced to produce different brainwave patterns, it can conversely affect a person's state. For example, when the human brain is induced to produce alpha waves, the person may also be brought into a state of sudden inspiration, mental and physical relaxation, and focused attention.

[0025] By adjusting the frequency of the audio through the frequency adjuster 130, the frequency difference between the first frequency of the audio in the left ear and the second frequency of the audio in the right ear can be set, so that the user's brain is induced to produce beta waves, alpha waves, theta waves, delta waves, gamma waves or other brain waves, and the user enters the aforementioned corresponding state, so as to achieve effects such as improving concentration, soothing sleep, relieving stress, and entering meditation.

[0026] In this embodiment, the frequency difference can automatically cycle and change over time. That is, this frequency difference is not fixed. Furthermore, without human intervention, this frequency difference will automatically change according to a default method. Additionally, the method of changing this frequency difference can be preset. Alternatively, there can be multiple methods, and the user can choose which one to use. Moreover, before determining the method of changing the frequency difference, the user's physiological state is detected, which can better determine the method of changing the frequency difference to reflect the differences in the user's physiological state. However, an interface can also be provided to allow the user to adjust the method of changing the frequency difference themselves. For example, the sound adjustment device 100 can be a mobile phone, and the mobile phone can also selectively provide a corresponding application. Through the interface provided by the application, the user can adjust the frequency difference or the method of changing the frequency difference. Of course, the user can also allow the sound adjustment device 100 to adjust the audio in different ways according to the different physiological state information received, using a default method.

[0027] For example, the frequency difference can automatically and segmentally cycle between 8 Hz and 12 Hz, with each change being 0.1 Hz, and maintaining the same frequency difference for 10 seconds after each change. Automatically and segmentally cycling between 8 Hz and 12 Hz means, for example, gradually changing from 8 Hz to 12 Hz and then gradually changing back to 8 Hz, or repeatedly changing from 8 Hz to 12 Hz, or repeatedly changing from 12 Hz to 8 Hz.

[0028] In this embodiment, the frequency difference can automatically cycle between 0.5 Hz and 4 Hz to induce delta waves, between 4 Hz and 8 Hz to induce theta waves, between 8 Hz and 12 Hz to induce alpha waves, between 12 Hz and 20 Hz to induce beta waves, and between 25 Hz and 40 Hz to induce gamma waves. Furthermore, in this embodiment, if the time period is insufficient, the frequency difference can simply increase or decrease gradually.

[0029] Each user's brain is not only responsive to a single frequency difference, but typically to multiple frequency differences. Because the sound adjustment device of this embodiment induces brainwaves in users through automatically cyclically changing frequency differences, it can produce optimal induction effects across multiple frequency differences. While a subject may experience a better induction effect with a single input frequency difference, the duration of this effect may be short. Since the sound adjustment device of this embodiment induces brainwaves through automatically cyclically changing frequency differences within a selected range, a different frequency difference can be used after the user's brain becomes fatigued, resulting in another optimal induction effect. Ultimately, the sound adjustment device of this embodiment can produce optimal brainwave induction effects over a longer period.

[0030] In this embodiment, the processor 54 is separate from the sound adjustment device 100, and the physiological state information receiving component 120 wirelessly receives physiological state information. For example, the processor 54 may be a cloud device, receiving physiological information wirelessly or via a wired network from the physiological information sensor 52. The processor 54 determines the physiological state information based on the physiological information in a preset manner, and then wirelessly transmits the physiological state information to the physiological state information receiving component 120. Optionally, when the processor 54 determines the physiological state information, a professional may assist in confirming the physiological state information, and adjust the physiological state information transmitted to the physiological state information receiving component 120 if necessary.

[0031] In this embodiment, the audio receiving component 110 can receive audio from an external audio source 20 wirelessly or via a wired network. The audio can be stereo or mono, and the present invention is not limited thereto. The left ear speaker 12 and the right ear speaker 14 can be a pair of headphones, for example, using a dynamic driver, a balanced armature driver, a bone conduction driver, or other types of speakers.

[0032] Figure 2 This is a circuit block diagram of a sound supply system and its sound adjustment device according to another embodiment of the present invention. The sound supply system 60 of this embodiment and... Figure 1 The sound supply system 50 is largely the same as the sound supply system 60 in this embodiment; the main differences will be described here. In the sound supply system 60 of this embodiment, the sound adjustment device 102 further includes a sound source 160, and the processor 150 is built into the sound adjustment device 102. The sound source 160 is signal-connected to the audio receiving component 110 and used to provide audio. The sound source 160 may have pre-stored audio, such as general music, user-recorded audio, program-generated audio, or other audio.

[0033] In one embodiment (not shown), only the audio source may be built into the sound adjustment device, while the processor is not part of the sound adjustment device. In another embodiment (not shown), only the processor may be built into the sound adjustment device, while the audio source is not part of the sound adjustment device.

[0034] Figure 3 This is a circuit block diagram of a sound adjustment device according to another embodiment of the present invention. The sound adjustment device 104 in this embodiment is... Figure 1 The sound adjustment device 104 of this embodiment is largely the same as the sound adjustment device 100; the differences between the two will be mainly described here. The sound adjustment device 104 of this embodiment includes an audio receiving component 110, a frequency adjuster 130, and an output port 140, but does not include… Figure 1 The physiological state information receiving component 120. The frequency difference is determined by the frequency adjuster 130. Therefore, the sound adjustment device 104 in this embodiment does not determine the frequency difference based on the physiological state information, but determines the frequency difference using a default mode or a mode selected by the user, and obtains the corresponding effect when hearing sound waves.

[0035] In summary, in the sound adjustment device and sound supply system of the present invention, the sound waves received by the two ears have a frequency difference, and the frequency difference is determined by a frequency adjuster, for example, but not limited to, based on physiological state information. When the frequency difference is determined based on physiological state information, the user's physiological state can be judged more accurately, and the appropriate frequency difference can be determined based on the user's physiological state, so that the user hears the sound waves and produces the corresponding effect.
