[0040] The bottom of the bottom shell 12 is fixedly connected to the base frame 17, and the base frame 17 is fixedly connected to the adjustment assembly 18;

[0041] A pressure sensor is installed inside the pillow core 13. A mounting post is provided in the middle of one side of the pillow core 13, and a conductive part 16 is installed on the mounting post. The conductive part 16 is electrically connected to the pressure sensor and two directional speakers 15.

[0042] The adjustment assembly 18 includes a connecting sleeve 181, which is sleeved and fixed on one side of the base frame 17; the side of the connecting sleeve 181 away from the base frame 17 is rotatably connected to the adjustment seat 182 via an adjustable hinge; the end of the adjustment seat 182 away from the connecting sleeve 181 is connected to the connecting frame 183.

[0043] The adjusting seat 182 includes a seat body 1821, one end of which is rotatably connected to the connecting sleeve 181 via an adjustable hinge; the bottom of the seat body 1821 is provided with two symmetrical sliding grooves 1822.

[0044] The base 1821 has a plurality of slots 1823 arranged in a straight line at the middle of one end near the connecting frame 183, and the plurality of slots 1823 are located between two sliding grooves 1822.

[0045] By adopting the above technical solution, after the patient's head presses against the pillow core 13, the pressure sensor in the pillow core 13 transmits a signal to the controller 2. The controller 2 can then control the two directional speakers 15 to play preset audio that can soothe tension, thereby reducing the patient's anxiety and fear, and reducing the difficulty of the doctor's work. In addition, the two directional speakers 15 can concentrate the sound energy near the patient's ears, improving the soothing effect on the patient while also preventing the played sound from interfering with the doctor's normal operation.

[0046] In this embodiment, the connecting frame 183 includes a frame 1831, the bottom of which is fixedly connected to the dental chair; two sliders 1832 are symmetrically fixedly connected to the top two ends of the frame 1831, and the two sliders 1832 are respectively located in two sliding grooves 1822.

[0047] The frame 1831 has an inner groove on the upper end of the side away from the connecting sleeve 181, and a spring 1835 is provided in the inner groove;

[0048] The frame 1831 has a lever 1834 in its inner groove; the spring 1835 is located below the lever 1834, and the bottom of the spring 1835 is in contact with the inner wall of the frame 1831, and the top of the spring 1835 is in contact with the bottom of the lever 1834.

[0050] The top of the push block 1834 is fixedly connected to a locking block 1833, which corresponds to the position of the locking slot 1823 and has the same shape as the locking slot 1823.

[0051] By adopting the above technical solution, the connecting sleeve 181 and the adjusting seat 182 work together to support the pillow core 13. At the same time, applying a certain force allows the pillow core 13 to rotate around the adjustable hinge, thereby changing the angle of the pillow core 13. By pressing down the lever 1834, the adjusting seat 182 can be moved laterally, thereby allowing the pillow core 13 to move laterally and change its position.

Doctors can control the playback, stop or switch of preset audio through physical switches, virtual buttons on the touch screen display, or voice recognition module.

[0055] As a further explanation of the above embodiments:

[0056] I. Working principle of each module of controller 2

[0057] 1. Touchscreen display

[0058] Core principle: Based on capacitive or resistive sensing technology, human-computer interaction and status feedback are realized.

[0059] When a user touches the screen, a capacitive screen senses the current from the human body, causing a change in capacitance between the electrodes. A resistive screen uses pressure to make the upper and lower conductive layers contact, causing a change in resistance. The screen converts the touch position into an electrical signal and transmits it to the controller.

[0060] After the controller analyzes the signal, it performs the corresponding operation (such as switching audio content or adjusting volume) and provides real-time feedback on the operation results (such as current playback progress and volume value) through the display screen.

[0061] 2. Physical switch module

[0062] Core principle: The function is directly triggered by controlling the circuit signal through the on / off state of the mechanical structure.

[0063] Physical switches (such as buttons and knobs) contain conductive contacts. When pressed or rotated, the contacts are connected or disconnected, generating high and low level signals (such as "connected is 1, disconnected is 0").

[0064] The signal is transmitted directly to controller 2, which executes the command according to the preset logic (such as "press and hold the button for 3 seconds to start voice interaction" or "rotate the knob to adjust the volume"). It is suitable for scenarios that require rapid operation or emergency start and stop.

[0065] 3. Wireless networking module

[0066] Core principle: Wireless data transmission is achieved through wireless communication protocols (such as Wi-Fi, Bluetooth, 4G / 5G).

[0067] The module has a built-in radio frequency chip and antenna. It receives data to be transmitted from the controller (such as device usage status and fault codes), encodes it, and sends it to the gateway or server via electromagnetic waves. At the same time, it receives external data (such as remotely updated audio files and control commands), decodes it, and transmits it to the controller.

[0068] Functions include: remotely monitoring device status, pushing audio resources, and synchronizing user settings.

[0069] 4. Audio playback module (amplifier)

[0070] Core principle: Amplify the audio signal to drive the directional speaker 15 to produce sound.

[0071] The audio electrical signal (such as voice command response, treatment instruction audio) transmitted by the receiver controller 2 is amplified into an electrical signal with sufficient power through a power amplifier circuit (composed of transistors, integrated circuits, etc.) to ensure that the signal strength can drive the directional speaker 15 to vibrate and produce sound.

[0072] It can also receive volume adjustment commands from the controller, and adjust the output power by changing the amplification factor to achieve volume control.

[0073] 5. Speech Recognition Module

[0074] Core principle: Converting speech signals into text commands to achieve human-computer voice interaction.

[0075] The system receives analog voice signals transmitted from the microphone, converts them into digital signals through analog-to-digital conversion, and then uses built-in algorithms (such as voice feature extraction and neural network models) to recognize them. It matches the preset command library (such as "play music" and "pause") and finally transmits the recognition results (text or command code) to the controller, which then executes the corresponding operation.

[0076] II. Module Connection Principle

[0077] 1. Connection principle between audio playback module (amplifier) ​​and directional speaker 15

[0078] Physical connection: Usually connected via audio cables (such as shielded cables), with the output of the power amplifier connected to the input of the directional speaker (terminal block) to ensure stable transmission of the amplified audio signal.

[0079] Signal transmission logic: The power amplifier transmits the amplified electrical signal (alternating current) to the transducer of the directional speaker. The current drives the transducer to vibrate, causing the speaker to focus the sound waves directionally (propagating only towards the patient's head area) through a specific structure (such as ultrasonic modulation), thus achieving directional sound emission. The controller can indirectly control the direction, volume, and sound quality of the directional speaker by adjusting the frequency and amplitude of the power amplifier's output signal.

[0080] 2. Connection principle between the voice recognition module and the microphone

[0081] Physical connection: The microphone is connected to the input of the voice recognition module via an audio cable (such as a 3.5mm interface cable), and some are wireless connections (such as Bluetooth microphones, which transmit wireless signals).

[0082] Signal transmission logic: The microphone converts the collected voice (sound waves) into a weak analog electrical signal and transmits it to the voice recognition module. The module filters, amplifies, and performs analog-to-digital conversion on the signal before performing voice recognition processing and finally sending the recognition result to the controller.

[0083] 3. Connection principle between pressure sensor and controller 2

[0084] Physical connection: The output terminal of the pressure sensor is connected to the signal input terminal of the controller via a wire. Some of them use digital interfaces such as I2C and SPI (suitable for digital pressure sensors).

[0085] Signal transmission logic: The pressure sensor transmits the detected pressure signal (analog or digital) to the controller 2. The controller 2 converts it into a processable digital signal through a built-in analog-to-digital converter (if it is an analog signal). Then, the signal strength is analyzed by an algorithm to determine the contact status of the patient's head (such as whether it is in place or the pressure changes), providing a basis for function triggering (such as allowing the directional speaker to be activated only when pressure is detected).

[0086] Through the collaboration and connection of the above modules, the dental chair headrest realizes a complete process of "perception-interaction-response", improving the intelligence and convenience of use.

[0087] The working principle of this utility model is as follows: After the patient's head presses against the pillow core 13, the pressure sensor in the pillow core 13 transmits a signal to the controller 2. The controller 2 can then control the two directional speakers 15 to play preset audio that can soothe tension, thereby reducing the patient's anxiety and fear and reducing the difficulty of the doctor's work. In addition, the two directional speakers 15 can concentrate the sound energy near the patient's ears, which can improve the soothing effect on the patient and also prevent the played sound from affecting the doctor's normal operation.

[0088] The connecting sleeve 181 and the adjusting seat 182 work together to support the pillow core 13. At the same time, applying a certain force allows the pillow core 13 to rotate around the adjustable hinge, thereby changing the angle of the pillow core 13. By pressing down the lever 1834, the adjusting seat 182 can be moved laterally, thereby allowing the pillow core 13 to move laterally and change its position. By changing the angle and position of the pillow core 13, patients of different heights and body types can easily adjust the pillow core 13 to the most comfortable position themselves.

[0089] Furthermore, it should be understood that although this specification describes embodiments, not every embodiment contains only one independent technical solution. This narrative style is merely for clarity. Those skilled in the art should consider the specification as a whole, and the technical solutions in each embodiment can also be appropriately combined to form other embodiments that can be understood by those skilled in the art.
