Description
Technical Field
[0001] This invention relates to the field of intelligent physiotherapy technology, specifically to an intelligent music therapy device and system. Background Technology
[0002] Music therapy relies on the principles of psychoacoustics and autonomic nervous system regulation. It stimulates the auditory nerve with specific beats and frequency frequencies, regulating the activity of the parasympathetic nervous system to achieve mood-regulating effects such as anxiety relief, relaxation, and sleep aid. It is currently widely used in psychological counseling, workplace stress reduction, and sleep intervention. Several music therapy devices have emerged on the market, with fixed music relaxation chairs being the most popular. These devices have stereo players fixed to the left and right sides of the chair, providing music therapy with preset two-channel tracks.
[0003] However, during actual physical therapy, the user's head posture is not always kept in a standard centered position. Driven by their own emotions such as tension, irritability, and depression, the body will unconsciously perform postural behaviors such as tilting the head to the side or making slight twists, causing the actual transmission distance between the left and right ears and the fixed speakers on both sides to no longer be symmetrical and equal. After the head is tilted, the ear closer to the sound source will receive the sound waves first, creating an additional physical transmission time difference. At the same time, the attenuation is smaller at close range, and the received sound pressure level is higher, thus introducing additional ITD and ILD differences that are not designed for use. The main goal of music therapy is to inhibit sympathetic nerve excitation and activate parasympathetic nerves to achieve physical and mental relaxation. When the sound field orientation is continuously shifted and the sound source location is erratic, the auditory cortex of the brain needs to continuously make orientation judgments and error corrections to maintain the perception of the sound source's orientation. This is an additional cognitive neural consumption, which indirectly maintains a mild state of tension in the sympathetic nervous system. This contradicts the core goal of healing and relaxation. At the same time, abnormal ITD and ILD will cause the brain to judge the sound source as biased to one side, resulting in virtual sound field distortion. The auditory cortex is forced to continuously make orientation corrections, which consumes neural computing power, hinders the induction of alpha relaxation brain waves and the regulation of the parasympathetic nervous system, and ultimately weakens the therapeutic effect of music.
[0004] Therefore, this invention proposes an intelligent music therapy device and system to reduce the negative impact of the user's head tilt on the music therapy process. Summary of the Invention
[0005] To address the aforementioned issues, this invention provides an intelligent music therapy device and system that senses the user's head tilt posture and synchronously adjusts the positions of the two players to dynamically balance the distance between the ears and the sound source, reduce the additional binaural time difference and sound intensity difference caused by head tilt, stabilize the stereo sound field, reduce the interference of head posture changes on audio synthesis, and ensure the music therapy effect.
[0006] To achieve the above objectives, the technical solution of the present invention is as follows: A smart music therapy device includes a recliner, an atmosphere cover installed at the top of the recliner, an arc-shaped guide seat fixedly connected to the outer surface of the atmosphere cover, and first sliding grooves symmetrically distributed along the length of the guide seat on the outer side of the guide seat; an adjustment component is slidably connected inside the guide seat, and a playback component for playing music is fixedly connected to both ends of the adjustment component, and the two playback components are respectively slidably engaged with the two first sliding grooves; a neck support is fixedly connected to the surface of the recliner, and a second sliding groove is opened on the side of the neck support away from the recliner, and a strain component for sliding according to the user's head rotation is slidably engaged in the second sliding groove; The adjustment component is used to slide left and right along the first slide groove according to the sliding condition of the strain component, and drive the two broadcast components to slide synchronously along the length of the guide seat.
[0007] Furthermore, the guide seat has an arc-shaped structure and is located directly behind the recliner.
[0008] Furthermore, the adjustment assembly includes a balance cavity located in the center of the guide seat. The balance cavity is provided with a balance rod that is slidably connected to the guide seat. The two ends of the balance rod extend into two first sliding grooves and are fixedly connected to the broadcasting assembly. A piston block that slides with the inner wall of the balance cavity is fixedly connected to the balance rod. The balance cavity is divided into a left sliding cavity and a right sliding cavity by the piston block. A first spring and a second spring are respectively provided in the left sliding cavity and the right sliding cavity. The two ends of the first spring are fixedly connected to the side wall of the left sliding cavity and the piston block, respectively. The two ends of the second spring are fixedly connected to the side wall of the right sliding cavity and the piston block, respectively. Both the left and right sliding cavities are connected to the strain gauge assembly.
[0009] Furthermore, the strain assembly includes symmetrically arranged variable cavities inside the neck support, each variable cavity having a strain rod slidably fitted inside. The ends of the two strain rods, which are close to each other, extend into the second sliding groove and are fixedly connected to a force-bearing seat. The force-bearing seats are slidably fitted to the outer surface of the neck support. The sides of the two variable cavities away from the strain rods are connected to a conveying channel, and the ends of the two conveying channels away from the variable cavities are respectively connected to the left sliding cavity and the right sliding cavity.
[0010] Furthermore, the cross-sections of both load-bearing seats are triangular structures; the ends of the two load-bearing seats that are close to each other are both inclined surfaces, and the inclined surfaces are both convex curved surface structures.
[0011] Furthermore, each load-bearing seat consists of an upper section and a lower section. The lower section of the load-bearing seat slides into the side surface of the neck support, and the upper section slides into the top of the neck support. The upper section of the load-bearing seat is an arc-shaped structure.
[0012] Furthermore, the surface of the support seat is provided with several auxiliary grooves arranged in an array along the length of the support seat.
[0013] Furthermore, each of the broadcasting components includes a first fixed seat that slides and engages with the first slide groove, and each of the first fixed seats has a music player embedded within it.
[0014] Furthermore, each of the broadcasting components includes a first fixed seat that slides with the first slide groove, and a second fixed seat located below the guide seat is fixedly connected to the outer surface of the first fixed seat. Each of the second fixed seats has a music player embedded inside.
[0015] This solution also provides an intelligent music therapy system, including: The audio output module is used to output therapeutic audio to the user's ears; The posture sensing module is used to support and compress the back of the user's neck and convert the lateral pressure generated by the user's head tilt into the corresponding displacement stroke. The strain module is used to convert the displacement stroke generated by the attitude sensing module into pressure change, and then convert the pressure change into a corresponding head deflection compensation amount; based on the head deflection compensation amount, the position of the audio sound generation module relative to the user's ears is adjusted.
[0016] The above solution has the following beneficial effects: Compared with existing music relaxation chairs, this solution uses the user's unconscious head turning posture to sense the lateral compression displacement in real time through the back neck support seat. The mechanical displacement is converted into fluid pressure changes through the changing cavity and delivery channel to drive the piston block and balance rod inside the balance cavity to adaptively slide. Simultaneously, it drives the music players on both sides to adjust their positions laterally along the arc-shaped guide seat, thereby matching the head turning angle in real time and dynamically correcting the relative distance between the music players on both sides and the user's ears. It always maintains a symmetrical and balanced state between the sound sources on both sides and the distance between the ears, effectively reducing the additional physical ITD and ILD differences caused by changes in head posture, improving the problems of sound field offset, sound image distortion, and uneven loudness between the ears, and allowing the preset stereo sound field parameters to accurately act on the user's auditory nerves.
[0017] Additional aspects and advantages of the invention will be set forth in part in the description which follows, and in part will be obvious from the description, or may be learned by practice of the invention. Attached Figure Description

Those skilled in the art can understand the specific meaning of the above terms in this invention based on the specific circumstances.
[0023] The following detailed description illustrates the specific implementation method: Example
[0024] like Figure 1 and Figure 2 As shown, a smart music therapy device includes a recliner 1 and an ambient light hood 2, which can be referenced from commercially available music relaxation chairs (with control panels).
[0025] In actual physical therapy, when the user's head posture deviation leads to additional ITD and ILD differences that are not designed to be present, this solution specifically combines... Figure 3 As shown, an arc-shaped guide seat 3 is integrally formed on the outer surface of the atmosphere cover 2. First grooves 301, symmetrically distributed along the length of the guide seat 3, are formed on the outer side of the guide seat 3. Simultaneously, combined with… Figure 6 and Figure 7 As shown, a balance cavity 306 is located in the center of the guide seat 3. A balance rod 302, slidably connected to the guide seat 3, is disposed within the balance cavity 306. Both ends of the balance rod 302 extend into two first sliding grooves 301 and are screwed to the audio playback components. A piston block 307, which slidably engages with the inner wall of the balance cavity 306, is fixedly connected to the balance rod 302. The balance cavity 306 is divided into a left sliding cavity and a right sliding cavity by the piston block 307. A first spring 305 and a second spring are respectively disposed within the left and right sliding cavities. The two ends of the first spring 305 are bonded to the side wall of the left sliding cavity and the piston block 307, respectively, and the two ends of the second spring are bonded to the side wall of the right sliding cavity and the piston block 307, respectively. Each audio playback component includes a first fixed seat 303 that slidably engages with the first sliding groove 301, and each first fixed seat 303 has a music player embedded within it. Furthermore, when the balance bar 302 and piston block 307 slide within the balance cavity 306, the first fixed seats 303 on both sides of the balance bar 302 slide synchronously, meaning that the music players on both sides rotate around the center point of the guide seat 3. In addition, when the balance bar 302 is in its initial position, the two music players are symmetrically distributed on both sides of the recliner 1; the guide seat 3 has a superior arc structure and is located directly behind the recliner 1, adapting to the user's normal lateral head tilt angle during physiotherapy, and reserving sufficient travel margin for the lateral sliding of the balance bar 302.
[0026] Specifically, in combination Figure 4 and Figure 5 As shown, the surface of the recliner 1 is integrally formed with a neck support 4 located inside the atmosphere cover 2. The neck support 4 has a second sliding groove 401 on the side away from the recliner 1. At the same time, combined with Figure 6 and Figure 7As shown, the neck support 4 has symmetrically opened variable cavities 403 inside, and strain rods 402 are slidably fitted in each variable cavity 403. The two strain rods 402 are close to each other, and one end of each extends into the second sliding groove 401 and is bonded to a force-bearing seat 5. The force-bearing seats 5 are slidably fitted with the outer surface of the neck support 4. Both force-bearing seats 5 have triangular cross-sections; the ends of both force-bearing seats 5 that are close to each other are inclined surfaces, and the inclined surfaces are convex curved surfaces. The triangular cross-sections combined with the inner convex curved inclined surfaces conform to the rounded physiological contours of the back of the neck. Compared with flat straight surfaces, the curved surfaces can achieve surface contact with the neck skin rather than line contact. When the head undergoes a slight lateral deflection, the lateral pressure of the neck can be smoothly applied to the curved surface of the corresponding force-bearing seat 5, and the pressure transmission is more direct, so as to capture slight head deflection movements and improve the sensitivity of head posture movement acquisition. In addition, each force-bearing seat 5 consists of an upper section and a lower section. The lower section of each force-bearing seat 5 slides with the side surface of the neck support 4, and the upper section of each force-bearing seat 5 slides with the top of the neck support 4. The upper section's arc conforms to the arc surface at the junction of the head and neck, adapting to the curvature of the upper part of the neck, while the lower section conforms to the vertical contours on both sides of the neck. The upper and lower sections correspond to the physiological curves of different areas of the neck, which improves comfort and further enhances the continuity and accuracy of deflection pressure acquisition.
[0027] Both variable chambers 403 have a conveying channel 404 connected to the side away from the strain rod 402. The ends of the two conveying channels 404 away from the variable chambers 403 are connected to the left sliding chamber and the right sliding chamber, respectively. During the user's lying-down physiotherapy, if the head turns to the side, the back of the neck will correspondingly compress the force seat 5 on the side of the turn, forcing the force seat 5 on that side to slide along the second slide groove 401 and push the strain rod 402 to retract into the variable chamber 403. This reduces the internal volume of the variable chamber 403 on the corresponding side and increases the internal fluid pressure. The volume of the unpressurized variable chamber 403 on the other side remains normal and the pressure is relatively constant. The high-pressure variable chamber 403 transmits the pressure difference to the left or right sliding chamber corresponding to the balance chamber 306 through the corresponding conveying channel 404, driving the piston block 307 to slide laterally to the side with less pressure, simultaneously compressing the spring on the corresponding side and stretching the spring on the other side. During the movement of piston block 307, the balance bar 302 slides as a whole, thereby pulling the first fixed seat 303 at both ends of the balance bar 302 and the embedded music player to make adaptive lateral displacement along the first slide groove 301 and the arc-shaped guide seat 3, and finely adjusting the relative position of the two players in real time according to the direction of head rotation. Through this purely mechanical fluid linkage structure, the deviation in the distance between the ears and the sound source caused by head rotation can be dynamically compensated, and the additional ITD and ILD differences introduced by the change in head posture can be offset. When the user's head returns to the centered position, the neck compression force disappears, and the elastic restoring force of the springs on both sides pushes piston block 307, balance bar 302 and the two end playback components to automatically return to the centered and symmetrical initial position, always ensuring the balance and stability of the stereo sound field, effectively avoiding sound field deviation and sound image distortion problems, and ensuring the accuracy and stability of music therapy.
[0028] In addition, the surface of the recliner is screwed to a curved headrest (not shown in the figure). A sponge layer is adhered to the inner side of the headrest (the side that contacts the head). The plane of the headrest is parallel to the plane of the guide seat. The headrest is integrally bent from a rigid strip of fiberglass material with directional elasticity. When subjected to force, this material only undergoes uniform elastic deformation on its own plane, while maintaining sufficient rigidity in other directions. During therapy, the headrest ensures that the user's head rotation plane remains parallel to the guide seat plane, effectively suppressing non-parallel head tilting movements and reducing misalignment of the head with the guide seat's sliding plane. This ensures that the lateral head rotation direction corresponds to the displacement adjustment direction of the balance bar and the sound-emitting components, allowing the neck compression force to act completely and positively on both sides of the support seats. This reduces force shift and sensor distortion caused by oblique movements, ensuring that the sliding adjustment of the music player adapts to the offset position of both ears.
[0029] The specific implementation process is as follows: The user lies on the recliner 1 with the back of the neck naturally resting between the two sets of support seats 5 of the neck support 4. In the initial state, the balance bar 302 is in the center position, and the music players on the left and right sides are symmetrically arranged with equal distance from the user's ears. Music therapy is carried out according to the preset dual-channel stereo sound.
[0030] During physiotherapy, if the user unconsciously turns their head to the left due to emotional tension, the left side of the back of the neck will compress the left force seat 5. The left force seat 5 slides inward along the second slide groove 401, pushing the strain rod 402 to compress the left change chamber 403. The fluid in the change chamber 403 is pressurized and transmitted to the left sliding chamber of the balance chamber 306 through the delivery channel 404. The pressure in the left sliding chamber is greater than that in the right sliding chamber, pushing the piston block 307 to slide to the right as a whole, compressing the right second spring and stretching the left first spring 305. The balance rod 302 moves to the right synchronously with the piston block 307, causing the music players at both ends to slide to the right synchronously along the first slide groove 301 of the arc-shaped guide seat 3. The left player moves to the right closer to the left ear, and the right player moves to the right synchronously, dynamically matching the position of the ears after the head is turned to the left, always maintaining the symmetrical distance between the ears and the sound source, and reducing additional ITD and ILD. Similarly, when the head is turned to the right, the music player shifts to the left to compensate.
[0031] When the user's emotions are calmed and the head returns to its central position, the neck no longer exerts unequal pressure on the single-sided force seat 5, the pressure in the left and right chambers is restored to balance, and the reset force of the first spring 305 and the second spring drives the piston block 307 and the balance rod 302 back to the center origin, and the music players on both sides are simultaneously reset to the initial symmetrical position.
[0032] Example 2:
[0033] As attached Figure 1 As shown, the difference from Embodiment 1 is that, in actual use, female users tend to have more hair, and long hair easily falls and accumulates in the area where it contacts the support seat 5 at the back of the neck. The hair strands can easily form a sliding layer between the support seat 5 and the neck skin, causing unstable friction and pressure transmission deviation when the head is turned. This leads to inaccurate strain acquisition, sensing lag, or even failure. Therefore, this solution, as... Figure 5 As shown, several auxiliary grooves are arranged in an array along the length of the force-bearing seat 5 on the surface of the force-bearing seat 5. By setting the array of auxiliary grooves, the scattered and piled long hair is orderly collected and confined inside the auxiliary grooves, so that the hair strands are less likely to form a slip pad on the force-bearing contact surface, reducing the slippage and uneven force caused by hair accumulation, ensuring that the lateral pressure generated by head deflection can be stably transmitted to the surface of the force-bearing seat 5, and improving the anti-interference ability of the posture sensing function.
[0034] Example 3:
[0035] The difference from Embodiment 2 is that this solution also provides a broadcasting component, specifically, such as... Figure 3 As shown, each of the audio components includes a first fixed seat 303 that slides and engages with the first slide groove 301. The first fixed seat 303 is screwed to a second fixed seat 304 located below the guide seat 3. Each of the second fixed seats 304 has a music player embedded in it. The music player is positioned below the guide seat 3 and in the bottom opening area of the ambient cover 2, which further optimizes the position of the music source, reduces the obstruction of the guide seat 3 and the ambient cover 2, reduces sound wave reflection and obstruction loss, and allows the therapeutic audio to be transmitted to the human ear area with low loss, thereby improving the audio transmission efficiency and listening clarity.
[0036] Example 4:
[0037] The difference from Embodiment 3 is that an angle sensor is embedded in the surface of a first fixed base 303, and the angle sensor is electrically connected to the control panel. According to Embodiment 1, the relative distance between the two music players and the ears is adjusted in real time to reduce the additional ITD and ILD differences caused by distance deviation. However, when the head is turned, there is a front-to-back misalignment difference between the left and right music players and the human ear: the music player on the turned side slides towards the rear of the recliner 1, and is more affected by the structure of the recliner 1 and the backrest, resulting in higher sound wave propagation obstruction, scattering, and attenuation; the music player on the other side is towards the front of the recliner 1, resulting in a clear sound field and less sound wave loss. This leads to inconsistent actual hearing loss and acoustic propagation conditions between the left and right ears, and simple physical equidistant adjustment still has the defect of sound field asymmetry. Therefore, the angle sensor in this solution is used to collect the deflection angle, deflection amplitude, and continuous change pattern of the balance bar 302 and the two music players relative to the initial center position in real time. The control panel then determines the current level of obstruction difference in the left and right sound fields based on the real-time offset angle amplitude and offset duration. A larger effective offset angle indicates a more significant difference in front-to-back obstruction between the left and right sides. Based on this determination, differentiated acoustic compensation adjustments are made to the left and right channels. High-frequency gain compensation and sound pressure level fine-tuning are applied to the channel on the rear side, where obstruction is stronger, to offset the sound wave attenuation caused by structural obstruction and hair obstruction. Moderate attenuation equalization is applied to the transparent channel on the front side to correct the listening deviation caused by the inconsistency of propagation obstacles on both sides. Combined with posture angle data, a secondary equalization of the sound field is performed to further reduce residual sound field errors caused by structural obstruction and environmental interference.
[0038] Example 5:
[0039] like Figure 8 As shown, an intelligent music therapy system includes: The audio module is used to output customized therapeutic audio in a two-channel stereo format. It can synchronize with the position displacement to complete the physical adjustment of the sound source, providing a sound field source for the user's ears. The posture sensing module is used to support and compress the back of the user's neck and convert the lateral pressure generated by the user's head tilt into the corresponding displacement stroke. The strain module is used to convert the displacement of the attitude sensing module into pressure change, and then convert the pressure change into a corresponding head deflection compensation; the position of the audio output module relative to the user's ears is adjusted based on the head deflection compensation. In addition, the posture sensing module is used to detect changes in pressure on both sides of the user's head in real time during non-standard head rotation states such as left and right swaying and oblique twisting, and converts the pressure difference and pressure distribution changes into corresponding posture adjustment parameters and outputs them. In actual physiotherapy, in addition to standard planar lateral rotation, users are prone to non-parallel rotation movements such as head tilting forward, backward, and oblique twisting. In these postures, the actual motion plane of the user's ears is not parallel to the sliding plane of the guide seat. It is difficult to match the spatial position of the ears by relying solely on a single lateral horizontal displacement compensation, and there will still be a slight sound field deviation. Therefore, the strain module generates a height compensation adjustment amount based on the posture adjustment parameters output by the posture sensing module, and adjusts the relative height position of the audio sound generation module accordingly.
[0040] Obviously, the above embodiments are merely illustrative examples for clear explanation and are not intended to limit the implementation. Those skilled in the art will recognize that other variations or modifications can be made based on the above description. It is neither necessary nor possible to exhaustively list all possible implementations here. However, obvious variations or modifications derived therefrom are still within the scope of protection of this invention.
