Description

Technical Field

[0001] The invention belongs to the technical field of music pillows, and in particular relates to a method for adaptively adjusting the volume of a music pillow speaker, a music pillow, a device and a medium. Background Art

[0002] The music pillow is a new type of healthy pillow. It has a speaker that can help people fall asleep comfortably while listening to music.

[0003] However, when using a music pillow in a sleep-aiding scenario, the prior art has the following shortcomings: turning over during sleep is a common phenomenon. When the user changes the position and / or orientation of the head on the music pillow, the loudness perceived by both ears may be different (sudden increase or decrease) due to the fixed speaker and the movement of the human body, thereby causing attention diversion and deviation, affecting the sleep process.

[0004] Especially when the user turns from sleeping on his back to sleeping on his side, the change in gravity on the head causes the loudness perceived by the ear close to the pillow to suddenly increase, while the loudness perceived by the other ear to suddenly drop. This auditory change will cause an increase in the level of arousal and reduce the sleep-aiding effect.

[0005] In addition, when the ambient noise changes or the sleep-aiding music tracks change, it will also affect the loudness perceived by both ears.

[0006] Other notes: Loudness is the human ear's perception of the strength of sound. It describes the loudness of a sound and represents the human ear's subjective perception of the sound. Loudness is closely related to the volume of the speaker (sound pressure level), but the sound will attenuate and change many times between the time the music is emitted from the speaker and the time it is received by the human ear. In the use scenario of the music pillow, the factors affecting the loudness of music are as follows:

[0007] (1) The distance between the human ear and the speaker. The greater the distance, the greater the attenuation. The distance is usually affected by the user's position on the pillow.

[0008] (2) The medium of sound transmission. Different materials absorb sound to different degrees. For example, sponge has a higher sound absorption coefficient, while air has a lower one. This factor is usually affected by the material of the pillow.

[0009] (3) Background noise: The louder the background noise is when music is playing, the lower the loudness of the music perceived by the human ear;

[0010] (4) The frequency of sleep-aiding music. The human ear has different loudness sensitivity values ​​for sounds of different frequencies. The human ear is less sensitive to low-frequency and high-frequency sounds, and requires a higher sound pressure level to achieve the same loudness perception as mid-frequency sounds.

[0011] (5) Sleeping stage. Summary of the invention

[0012] The present invention aims to solve the problem that the volume of the existing music pillow does not change due to changes in the position or orientation of the human head, background noise or sleep-aiding music, and provides a method for adaptively adjusting the volume of a music pillow speaker, so as to reduce the loudness changes felt by the user caused by changes in the head, background noise or sleep-aiding music, and strive to achieve a non-perceptual change in auditory perception, thereby ensuring the sleep-aiding effect of the music pillow. The present invention also provides a music pillow, a computer device and a computer-readable storage medium.

[0013] To achieve the above object, the present invention adopts the following technical solution: a method for adaptively adjusting the volume of a music pillow speaker, the method comprising:

[0014] Step S1, establishing a relationship between the loudness of the comfortable sleep-aiding music and the volume of the speaker, and at least one of the distance between the left and right ears of the user and the speaker, the ambient noise, the frequency of the sleep-aiding music, and the user's sleep stage;

[0015] Step S2, detecting the distance between the left and right ears of the user and the speaker, the ambient noise, the frequency of the sleep-aiding music, and the user's sleep stage, adjusting the speaker volume to a subjectively comfortable level, and determining a comfortable sleep-aiding music loudness based on the speaker volume and at least one of the distance between the left and right ears of the user and the speaker, the ambient noise, the frequency of the sleep-aiding music, and the user's sleep stage;

[0016] Step S3: When at least one of the distance between the left and right ears and the speaker, the ambient noise, the frequency of the sleep-aiding music, and the user's sleep stage changes, the speaker volume is automatically adjusted to maintain a comfortable loudness of the sleep-aiding music.

[0017] The music pillow speaker volume adaptive adjustment method of the present invention establishes a numerical relationship between the comfortable sleep-aiding music loudness and the speaker volume (the speaker volume is a required influencing variable) and the distance between the user's left and right ears and the speaker, the ambient noise, the frequency of the sleep-aiding music and at least one of the user's sleep stage, and determines the comfortable sleep-aiding music loudness according to the speaker volume and at least one of the distance between the user's left and right ears and the speaker, the ambient noise and the frequency of the sleep-aiding music. When at least one of the distance between the left and right ears and the speaker, the ambient noise and the frequency of the sleep-aiding music changes, the speaker volume is automatically adjusted to maintain the comfortable sleep-aiding music loudness, so that when at least one of the distance between the left and right ears and the speaker (caused by the user's turning over, etc.), the ambient noise (when changing), and the frequency of the sleep-aiding music (when changing) changes, the comfortable sleep-aiding music loudness is still maintained. The adjusted speaker volume is the volume actually emitted by the speaker.

[0018] As an improvement, the method for adaptively adjusting the volume of a music pillow speaker comprises:

[0019] Step S1, establishing a numerical relationship between the loudness of the comfortable sleep-aiding music and the volume of the speaker and at least one of the distance between the left and right ears of the user and the speaker, the ambient noise, and the frequency of the sleep-aiding music;

[0020] Step S2, detecting at least one of the distance between the user's left and right ears and the speaker, the ambient noise, and the frequency of the sleep-aiding music, adjusting the speaker volume to a subjectively comfortable level, and determining a comfortable sleep-aiding music loudness based on the speaker volume and at least one of the distance between the user's left and right ears and the speaker, the ambient noise, and the frequency of the sleep-aiding music;

[0021] Step S3: When at least one of the distance between the left and right ears and the speaker, the ambient noise, and the frequency of the sleep-aiding music changes, the volume of the speaker is automatically adjusted to maintain the loudness of the comfortable sleep-aiding music.

[0022] As an improvement, in step S1, a numerical relationship is established between the loudness of the comfortable sleep-aiding music and the volume of the speaker, the distance between the user's left and right ears and the speaker, the ambient noise, and the frequency of the sleep-aiding music.

[0023] As an improvement, the loudness of comfortable sleep-aiding music is expressed as:

[0029] Use the following formula to calculate the masking coefficients N1 and N2 of the ambient noise on the loudness of the music in the left and right ears respectively;

[0030] N1=log 10 (L1 / E1)

[0032] Among them, L1 and L2 are the actual sound pressure levels of the speakers entering the left and right ears after attenuation by distance and pillow material, and E1 and E2 are the ambient noise entering the left and right ears.

[0033] As an improvement, the following formula is used to calculate the user's loudness sensitivity value M of the current sleep-aiding music;

[0035] f0 represents the average frequency or main frequency of the currently playing sleep-aiding music;

[0036] f1 represents the reference low frequency point, ranging from 20 to 250 Hz;

[0037] f2 represents the reference intermediate frequency point, which is between 250-2000Hz;

[0038] f3 represents the reference high frequency point, which is between 2000-20000Hz.

The initial speaker volume is determined according to the speaker volume, the distance between the left and right ears of the user and the speaker, the ambient noise, the frequency of the sleep-aiding music, and the user's sleep stage;

[0041] In step S3, when at least one of the distance between the left and right ears and the speaker, the ambient noise, the frequency of the sleep-aiding music, and the user's sleep stage changes, the speaker volume is automatically adjusted to maintain the comfortable loudness of the sleep-aiding music.
