Description

Technical Field

[0001] The invention relates to the technical field of pillows, in particular to a sound wave resonance system. Background Art

[0002] Pillows are an essential accessory in home bedding. Appropriate pillow designs and materials can help provide a comfortable experience for the user. Furthermore, suitable music can have a relaxing and stress-relieving effect. Music pillows that combine music with pillow functions should fully leverage the properties of music to achieve this relaxing effect. Furthermore, by integrating the auditory and tactile qualities of music, simultaneously stimulating sound waves with human cells and auditory nerves, a relaxing effect can be achieved under the right conditions. However, a current problem in this field is that traditional designs cause sonic resonance when the user lies sideways, causing ear discomfort. Furthermore, with existing music pillows, the intensity of the sonic resonance often decreases when the volume is lowered, while increasing it increases the intensity. This inconvenience prevents the user from independently adjusting the volume and resonance intensity. Furthermore, existing products lack sound source solutions suitable for sonic resonance, forcing users to select their own music. However, unscreened and verified music often contains fewer resonant low-frequency components, which can weaken the relaxing effect of sonic resonance. Summary of the Invention

DETAILED DESCRIPTION

[0032] The present invention will be further described below with reference to the accompanying drawings and specific embodiments so that those skilled in the art can better understand the present invention and implement it. However, the embodiments are not intended to limit the present invention.

[0033] Reference Figures 1 to 5 As shown, a sound wave resonance system of the present invention includes: a carrier 800 and:

[0034] The storage unit 100 is used to pre-store the filtered audio signal;

[0035] The trigger unit 200 is used to receive a trigger signal from a user;

[0036] The processing unit 300 is configured to perform frequency division and / or channel division processing on the filtered audio signal according to the trigger signal;

[0037] The sound generating unit 400 is configured to receive the filtered audio signal and / or the channel-separated audio signal, and generate sound according to the filtered audio signal and / or the channel-separated audio signal;

[0038] The resonance sound generating unit 500 is configured to receive a channel signal and generate sound and vibration according to the channel signal, wherein the channel signal is a signal obtained by frequency division and / or channel division of the filtered audio signal;

[0039] The resonance conduction unit 600 is configured to conduct the vibration to the carrier 800. The resonance conduction unit 600 includes a resonance conduction curved surface 802 disposed on the carrier 800. The resonance conduction curved surface 802 is capable of radiating and conducting the vibration signal. The resonance conduction curved surface 802 does not directly contact the human body. Instead, the resonance conduction curved surface 802 conducts the vibration to a portion of the carrier attached thereto. The portion of the carrier then conducts the vibration to the user of the headrest carrier.

[0040] The carrier 800 further includes a resonance chamber 801 disposed inside the carrier 800 , and a surface of the resonance chamber 801 forms the resonance conductive curved surface 802 .

[0041] Specifically, a first groove 803 is provided on the inner surface of the resonance chamber 801 , and the resonance sound-generating unit 500 is embedded in the first groove 803 , with a portion of the resonance sound-generating unit 500 exposed from the first groove 803 .

[0042] Specifically, when it is necessary to amplify the radiation conduction of resonance, the interior of the resonance chamber 801 is filled with a material with a density and hardness greater than that of the carrier 800; when it is necessary to weaken the radiation conduction of resonance, the interior of the resonance chamber 801 is filled with a material with a density and hardness smaller than that of the carrier 800; in order to reduce the vibration impact on the eardrum when lying on the side, the interior of the resonance chamber 801 is filled with a filling material for reducing the radiation conduction of resonance, and the density or hardness of the filling material is less than that of the carrier 800 material. The material of the carrier 800 can be memory foam, latex or other materials, and the density or hardness of the filling material is 60-80% of that of the carrier.

[0043] Specifically, the carrier 800 is a symmetrical structure, and a protruding structure 804 extends from one side of the carrier 800. The resonance chamber 801 is located on one side of the protruding structure 804. The protruding structure 804 is provided to facilitate supporting the user's neck.

[0044] Specifically, a second groove 805 is provided in the carrier 800, the sound unit 400 is provided in the second groove 805, the second groove 805 is connected to the sound transmission channel 806, and the side surface of the carrier 800 is provided with a sound outlet 807 connected to the sound transmission channel 806.

[0045] In this embodiment, the sound holes 807 are symmetrically arranged on both sides of the protruding structure 804. With this arrangement, most of the sound emitted by the sound unit 400 is transmitted from the sound holes 807 through the sound transmission channel 806, reducing the sound impact of the sound unit 400 on the ears of the user lying on the surface of the carrier 800.

[0046] In addition, for the sonic resonance system, when the input audio signal contains extremely low frequency, low frequency, and medium-low frequency components with relatively loud sound, the resonant sound-generating unit 500 will generate a large vibration that changes with the audio signal and is tactilely perceptible. Therefore, the present invention is also provided with an audio screening unit. The method for screening the audio signal according to the audio screening unit is as follows: the audio signal to be tested is input into the sonic resonance system, and the resonant sound-generating unit 500 operates at a voltage of 5V and a power of 2.5W. At this time, an acceleration curve is monitored, and the acceleration direction is perpendicular to the vertical direction of the bottom plane of the resonance chamber 801. The position of the acceleration is: the vertex of the conductive surface; the peak acceleration and average acceleration of the conductive surface during vibration are obtained according to the acceleration curve; and the audio signal that can achieve the resonance effect is screened according to the peak acceleration and the average acceleration.

[0047] More specifically, the method for screening the audio signal that can achieve the resonance effect based on the peak acceleration and the average acceleration is: the peak acceleration value is between 0.9-4.5m / s 2 The average acceleration value is between 0.5-4.5m / s 2 Audio signals between and are considered the filtered audio signals. Audio signals that meet these conditions can achieve a resonance effect on this sound wave resonance system. Furthermore, considering the relaxation and stress-relief effect, the audio signals must be relaxing music, white noise, or therapeutic audio such as human chanting, with a BPM (beats per minute) no higher than 159.

[0048] Specifically, it further includes: a communication unit 700, which is communicatively connected to the processing unit 300 and is used to achieve a communication connection with a host computer to receive the filtered audio signal.

[0049] Specifically, it also includes a power module, which can be a lithium battery, which is electrically connected to the processing unit 300 and is used to provide power supply for the operation of the processing unit 300.

[0050] Specifically, the storage unit 100 includes a memory card or a cloud server.

[0051] Specifically, the generating unit includes a music speaker. In this embodiment, an 8Ω, 1W music speaker is selected; the resonant sound generating unit 500 includes a low-frequency vibration enhancement speaker, which can convert the electrical signal into up and down vibrations. The vibration frequency is consistent with the signal frequency. When the frequency is between 20Hz-300Hz, the vibration of the low-frequency vibration enhancement speaker is manifested as large-scale vibration, and the maximum acceleration value of the surface vibration can reach 4-5m / s. 2 This embodiment uses a Deltawave L00035W-001 low-frequency vibration enhancement loudspeaker.

[0052] Specifically, the trigger unit 200 includes one or more of a remote control panel, a keypad, and a mobile terminal. The processing unit 300 includes an MCU. The communication unit 700 can be a Bluetooth communication module (Bluetooth IC) or a mobile communication module such as Wi-Fi. All of these units are located on a circuit board 900 within the carrier 800.

[0053] Specifically, when the trigger unit 200 is a remote control panel, it communicates with a remote control module mounted on the circuit board 900. The remote control module can be an infrared module, RF module, BLE module, etc. When the trigger unit 200 is a key panel, the lower part of the key panel is the corresponding key element on the circuit board 900. When the trigger unit 200 is a mobile terminal, it transmits and receives instructions and data via the BLE protocol or the A2DP protocol to achieve communication with the transmission unit and the MCU. The trigger unit 200 can implement user interactive operations such as music media playback control, music switching, volume adjustment, resonance intensity adjustment, timed shutdown, and power on and off.

[0054] The working method of the sound wave resonance system is as follows: the filtered audio is stored in the memory card of the circuit main board 900, or in the cloud; the processing unit 300 is controlled to start the circuit main board 900; the processing unit 300 sends the audio to be played, the media playback behavior to be performed, the alarm to be set, and other instructions to the Bluetooth IC and MCU in the circuit main board 900; the Bluetooth IC in the circuit main board 900 communicates with the processing unit 300 to keep the instructions and status dynamically updated; the cloud audio is transmitted to the Bluetooth IC through the Bluetooth media channel between the processing unit 300 and the Bluetooth IC; the MCU sends the audio in the memory card or the audio from the cloud to the amplifiers corresponding to the sound unit 400 and the resonant sound unit 500 after frequency division or channel division; wherein frequency division refers to sending the separated low-frequency signal to the resonant sound unit 500 through low-pass filtering. The corresponding amplifier, the audio signal sent to the amplifier of the sound unit 400 does not need low-pass filtering; the channel division means that the signal of one channel in the multi-channel of the audio signal is sent to the amplifier corresponding to the resonant sound unit 500, and the signal of another channel is sent to the amplifier corresponding to the sound unit 400. In this way, the signals of different channels can be targeted in content processing; for example, the channel signal sent to the resonant sound unit 500 should contain more low-frequency components, while the channel signal sent to the sound unit 400 should contain more mid- and high-frequency components. The content processing of these different channels is pre-processed in advance; through the gear parameters of the amplifier corresponding to the sound unit 400 and the amplifier of the resonant sound unit 500 provided by the processing unit 300, the two types of amplifiers update the gear parameters separately to achieve independent adjustment of the volume and resonance intensity.

[0055] Finally, it should be noted that the above specific implementation methods are only used to illustrate the technical solutions of the present invention and are not limiting. Although the present invention has been described in detail with reference to examples, those skilled in the art should understand that the technical solutions of the present invention can be modified or replaced by equivalents without departing from the spirit and scope of the technical solutions of the present invention, which should all be included in the scope of the claims of the present invention.
