[0031] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0032] Studies have shown that appropriate music can help the brain and body enter a state of relaxation as quickly as possible. People can listen to music while the volume of the music should be set at a medium or low volume. However, the music massage currently on the market will reduce the massage effect when the music is lowered.

[0033] The specific embodiments of the present invention will be further described below with reference to the accompanying drawings:

[0034] The utility model provides a dual-mode massage device with a Bluetooth speaker, which includes a normal massage mode and a rhythm massage mode. As shown in Figure 1, the massage device specifically includes a massage device body, an electrical control box, an audio unit, and a power adapter;

[0035] The massage device body can be, for example, a sofa as shown in FIG2 or a bed as shown in FIG3. The massage device body includes: a head massage unit 1 and a foot massage unit 2, both of which are equipped with massage components and a driving structure;

[0036] The massage parts are made of elastically deformable materials, such as latex, or wrinkle-resistant polymer materials. The cost factor can be used as a selection factor based on the actual applicable population, and the specific massage parts can also be taken into consideration to ultimately determine the material of the massage parts.

[0037] The electrical control box and the audio unit are installed on the massage device body; the electrical control box is connected to the head massage unit and the foot massage unit respectively; the electrical control box is connected to the audio unit using an AUX wire; and the electrical control box is connected to a power adapter.

[0038] In this embodiment, the above components are reasonably arranged in positions according to ergonomics. The installation position of each part can be determined according to the actual size of the massage body device, the actual application scenario of the massage body device, and even the personal habits and preferences of the specific user. It can be suitable for people of different ages and different working methods.

[0039] In this embodiment, the electrical control box includes: a control panel, a built-in DAC chip, a power amplifier chip and a vibration unit; the built-in DAC chip is connected to the power amplifier chip, and the power amplifier chip is connected to the vibration unit;

[0040] The control panel is external to the massage device and is connected to the built-in DAC chip. As shown in Figure 4, the user can switch between normal vibration mode and rhythmic massage mode through the control panel.

[0041] Normal vibration mode: The DAC can output a 20Hz-100Hz sine wave. By modifying the frequency and amplitude of the output waveform, different massage effects can be achieved. For example, long vibration: a fixed frequency of continuous vibration. Interval vibration: you can set the vibration to a certain period, then stop for a period, then repeat the vibration for a period of time. Triangle wave vibration: you can set the software to gradually increase the amplitude, then slowly decrease, then gradually increase and then gradually decrease, creating a triangle wave effect.

[0042] Music massage mode: There will be a sound source at the front end, which needs to come from another chip such as Bluetooth, USB flash drive, or AUX. While playing music, the chip will input the left and right channel signals to the vibration unit. The vibration unit collects the low-frequency signal in the music and then controls its own DAC output to simulate this signal. For example, choosing 50HZ to simulate this signal is more effective.

[0043] This embodiment implements low-frequency sonic massage. The two massage modes described above include fixed low-frequency massage and music-synchronized massage. For example, music-synchronized massage detects the rhythm of the music while it's playing, allowing the vibrator to mimic that rhythm and vibrate. The vibrator's output changes only with the rhythm, not with the volume of the music. This helps address the issue of the vibrator's output decreasing when the music is quiet.

[0044] In this embodiment, the audio unit includes: at least one Bluetooth chip with TWS function, an MCU control chip, a switching power supply chip, a current and voltage control chip, a DCDC step-down chip that can achieve a 40V voltage step-down, a DAC driver chip, a Class D amplifier chip for audio amplification, a miniaturized integrated speaker and a PCBA board.

[0045] The Bluetooth speaker is perfectly integrated into the entire system, and the matching remote control can control the Bluetooth speaker, such as play and pause, track switching, volume increase and decrease, etc.

[0046] In this embodiment, a cavity is opened on the back cover of the miniaturized integrated speaker to accommodate the PCBA board.

[0047] In another embodiment, the speakers may be separated as a single device, including a left channel speaker and a right channel speaker.

[0048] In this embodiment, as shown in Figure 6 of the specification, the power amplifier chip schematic diagram is shown; the Class D power amplifier chip model is TPA3110D2. The PIN pins are sequentially connected to a capacitor and a resistor, and then to different capacitor types, serving as DAC pins. The DAC pins serve as inputs connected to the DAC driver chip. The TPA3110D2 is a high-efficiency, 15W (per channel) Class D audio power amplifier from Texas Instruments, designed to drive bridged stereo speakers. It utilizes advanced EMI suppression technology, enabling the use of cost-effective ferrite bead filters at the output while meeting EMC requirements.

[0049] In this embodiment, the Class D power amplifier chip further includes OUTPL, OUTNL, OUTNR, and OUTPR pins; the OUTPL and OUTNL pins are connected in parallel and then connected to an inductor to form an SPL+ port; the OUTNR and OUTPR pins are connected in parallel and then connected to an inductor to form an SPL- port; the SPL+ port and SPL- port are used to output signals and connect to a miniaturized integrated speaker.

[0050] In another embodiment, the class D power amplifier chip model can be NTP8918, which has up to 32 segments of freely adjustable EQ points and efficient and accurate DRC power control;

[0051] In this embodiment, as shown in FIG7 , the current and voltage control chip uses the SC2998 chip, and the DCDC buck chip model for achieving 40V voltage step-down is the AP4008SD. The SC2998 is a step-down PWM controller that can drive dual-output load currents. The design allows the SC2998 to operate over a wide input voltage range of 9V to 45V. External compensation enables the feedback control loop to have good line and load regulation, and flexible peripheral design.

[0052] In this embodiment, the FB pin of the current and voltage control chip is connected to the capacitor and the inductor in sequence, and finally connected to the D1 and S2 pins of the DCDC buck chip that achieves a 40V voltage step-down.

[0053] In this embodiment, as shown in Figure 8, the switching power supply chip model is XL1509-5V, the OUTPUT pin is connected to the USB interface via an inductor, and the USB interface is used to connect peripherals via the AUX wiring. In practical applications, the output voltage can be adjusted by changing the parameters of the output capacitor and inductor, and operations such as short-circuit protection and over-temperature protection can be performed to ensure the safety and reliability of the chip. It should be noted that the input voltage of the chip must be able to reach a certain minimum voltage value to ensure the normal operation of the chip. In addition, the output current of the chip also has certain limitations, and the appropriate circuit solution should be selected according to the specific application scenario to ensure the stability and reliability of the chip.

[0054] In another embodiment, the chip model LM2675-5.0 can replace the switching power supply chip model XL1509-5V.

[0055] This new model uses Bluetooth TWS functionality. When two small beds are combined into one large bed, the two beds can be paired in TWS mode, enabling synchronized music playback. In practice, for example, both regular and rhythmic massage modes can be achieved. The rhythmic massage not only allows the massage rhythm to change with the audio rhythm, but also ensures that the massage output power does not decrease as the volume of the audio source decreases.

[0056] The above description of the disclosed embodiments will enable one skilled in the art to implement or use the present invention. Various modifications to these embodiments will be readily apparent to one skilled in the art, and the general principles defined herein may be implemented in other embodiments without departing from the spirit or scope of the present invention. Therefore, the present invention is not limited to the embodiments shown herein but is intended to conform to the widest scope consistent with the principles and novel features disclosed herein.
