[0038] The following specific embodiments illustrate the implementation of this utility model. Those skilled in the art can easily understand other advantages and effects of this utility model from the content disclosed in this specification. Obviously, the described embodiments are only some, not all, of the embodiments of this utility model. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.

[0039] See Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 5 and Figure 6 This utility model provides a CD playback device with a book-shaped design and ambient lighting. It is characterized by comprising a middle shell 1, a bottom shell 2, an upper flip-top 3, a CD tray 4, a mechanism assembly 5, and an LED light strip 6. The upper flip-top 3 is rotatably connected to the middle shell 1 via steel pins to form a book-like flip-top structure. The CD tray 4 is used to hold CDs, and it cooperates with the mechanism assembly 5 to read CD information. The LED light strip 6 is used to create ambient lighting, and it is fixed in place by a limiting structure at the mounting groove on the front of the middle shell 1.

[0040] Specifically, the CD player's flip-top structure rotates via a steel pin. The principle is to use the steel pin as a pivot, allowing the upper flip-top 3 to rotate smoothly around the middle shell 1, simulating the action of turning pages in a book. This not only gives the device a unique appearance but also makes it easier for users to handle CDs, satisfying their needs for both aesthetic appeal and ease of operation. The CD tray 4 and the mechanism assembly 5 work together to read CD information. When a CD is placed on the CD tray 4, the laser head in the mechanism assembly 5 emits a laser beam. By detecting the difference between the pits and the reflected light on the CD surface, the light signal is converted into an electrical signal. After processing using existing technologies, the audio signal is extracted, enabling music playback. The LED light strip 6 is fixed by the limiting structure of the middle shell 1. This limiting structure constrains the LED light strip 6 from multiple directions, ensuring its stable position during device operation and providing continuous and uniform ambient light, thus enhancing the user experience.

[0041] In this embodiment, a transparent disc 7 is also included, which is fixedly connected to the upper flip cover 3 through several hot-melt points.

[0042] Specifically, the transparent disc 7 is fixed to the upper flip cover 3 using a heat-fusion connection, based on the properties of thermoplastic materials. During the heat-fusion process, heat is applied to the connection area between the upper flip cover 3 and the transparent disc 7, melting the material in contact, which then cools and solidifies, forming a strong bond. This connection method offers high stability, ensuring that the transparent disc 7 is unlikely to detach during use. Simultaneously, the transparency of the disc 7 does not obstruct the internal lighting effects; light can be evenly diffused through the disc, complementing the book's design and further enhancing the device's aesthetics, providing users with a unique visual experience.

[0043] In this embodiment, the movement assembly 5 includes a movement body and a movement tray, with the movement body mounted on the movement tray; the movement tray is provided with a plurality of fan-shaped notch structure slots, which are connected to the structural columns of the middle shell 1 via shock-absorbing silicone.

[0044] Specifically, the mechanism itself is the core component for reading CD information. Mounted on the mechanism tray, it receives stable support. The mechanism tray is tightly connected to the mechanism body via screws and clips, ensuring the mechanism body does not wobble during operation. The fan-shaped notch structure and the damping silicone utilize the elasticity and damping properties of silicone. When the mechanism vibrates during operation, the vibration is transmitted to the fan-shaped notch structure, where the damping silicone absorbs the vibration energy, converting it into internal frictional heat. This reduces significant movement of the mechanism, preventing skipping caused by vibration, ensuring stable and continuous CD playback, and providing users with a high-quality audio playback experience.

[0045] In this embodiment, a main control circuit board 8 is also included. The main control circuit board 8 integrates digital tube display, DVD signal processing, audio amplification, motor drive and power management circuits. The main control circuit board 8 is fixed to the screw posts on the back of the bottom shell 2 by screw fastening.

[0046] Specifically, the main control circuit board 8, acting as the brain of the device, integrates relevant existing functional circuits. The digital tube display circuit controls the illumination of each segment of the digital tube to display the device's operating status information, such as the track being played and the playback time. The DVD signal processing circuit decodes and processes the received CD signal, converting it into recognizable audio and video signals (if the device supports video playback). The audio amplification circuit amplifies the decoded audio signal, enhancing its strength to drive the speakers to output clear and loud sound. The motor drive circuit controls the operation of the motors, including the CD tray 4 in / out motor and the mechanism rotation motor, ensuring the normal operation of all mechanical components. The power management circuit manages the device's power supply, stabilizing voltage and distributing current to provide appropriate power support for each circuit module. The main control circuit board 8 is secured to the bottom shell 2 with screws, ensuring a tight fit and reducing the impact of device vibration on circuit connections, thus guaranteeing stable operation.

[0047] In this embodiment, the CD tray 4 has a circular protrusion with an internal hollowed-out shape derived from the center of the tray at 60-degree intervals, for a total of 6 protrusions. The hollowed-out parts first cooperate with the screw posts of the middle shell 1, and then are locked onto the middle shell 1 by screws.

[0048] Specifically, from a structural fit perspective, the circular protrusions spaced 60 degrees from the center of the tray ensure even distribution of force on the CD tray 4 circumferentially, preventing deformation or installation misalignment due to excessive localized stress. The internal hollow design reduces the overall weight of the CD tray 4 and provides space for the screw posts of the middle shell 1. The dimensions of the hollow portion precisely match the outer diameter of the middle shell screw posts. When the CD tray 4 is assembled with the middle shell 1, the screw posts of the middle shell 1 can pass through the hollow portion of the circular protrusions, achieving initial positioning and ensuring accurate installation of the CD tray 4 on the middle shell 1. Subsequently, screws are used for fastening. The screws pass through the hollow portion of the circular protrusions and tightly engage with the internal threads of the screw posts of the middle shell 1, firmly fixing the CD tray 4 to the middle shell 1. This multi-point even fastening method further enhances the stability of the connection, effectively resisting vibrations generated during device operation, preventing the CD tray 4 from loosening, ensuring the CD remains in a stable reading position during playback, and reducing reading errors caused by tray movement.

[0049] In this embodiment, the upper part of the middle shell 1 is provided with a square function button slot and a rectangular electronic display screen 12 mounting area; the side of the middle shell 1 is provided with a diamond-shaped opening strip as a sound source external playback channel for the sound cavity assembly 9; the bottom of the middle shell 1 is provided with a cylindrical boss with a T-shaped concave for mounting foot pads 10; the side of the middle shell 1 is provided with double holes for passing a round rope through for assembly; the sound cavity assembly 9 is provided with two sets of identical rectangular plastic structural parts, and a speaker is placed inside the sound cavity and connected to the main control circuit board 8 through two red and black wires; the sound cavity assembly 9 is screwed onto the screw post of the middle shell 1.

[0050] See Figure 7 Specifically, the square function button slot and the rectangular electronic display screen 12 mounting area provide installation positions for the function button assembly 11 and the electronic display screen 12. The function button slot is designed so that the buttons are flush with the surface of the middle shell 1 after installation. The buttons are connected to the circuit contacts below via spring contacts or similar structures. When the user presses a button, the spring contacts deform and contact the circuit contacts, thereby triggering the corresponding circuit signal to control the device, such as play, pause, and track switching. The electronic display screen 12 is installed within the rectangular area and connected to the main control circuit board 8 via a ribbon cable. It receives display signals sent by the main control circuit board 8 and uses technologies such as LCD and LED displays to display the device's operating status in real time, such as playback progress and volume, allowing users to intuitively understand the device's status and improving operational convenience.

[0051] The rhomboid-shaped opening strip serves as the external sound channel for the sound cavity component 9. Based on acoustic principles, when sound propagates within the sound cavity, it encounters the rhomboid opening strip. Due to the special shape of the opening, the sound propagation is reduced, allowing it to be more concentrated and effectively transmitted outwards, improving sound quality and providing users with a better listening experience. The cylindrical boss with a T-shaped concave design facilitates the installation of the foot pad 10. The installation principle of the foot pad 10 utilizes the T-shaped structure's embedding fit; the T-shaped protrusion of the foot pad 10 is embedded into the T-shaped concave part of the cylindrical boss. Through friction and a tight fit, the foot pad 10 is securely installed, making the device more stable when placed and reducing the impact of vibration on the device. The dual-hole design allows for hanging of the device with a round rope, increasing the device's placement options. Users can thread a round rope through the dual holes to hang the device on a wall, hook, or other locations, meeting different usage needs.

[0052] The acoustic cavity assembly 9 comprises two sets of rectangular plastic structural components serving as the left and right channels, respectively. Speakers housed within the acoustic cavity are connected to the main control circuit board 8 via red and black wires. The red wire is typically connected to the positive terminal, and the black wire to the negative terminal. Audio signals are transmitted to the speakers through these wires, causing them to vibrate and produce sound. The two sets of speakers, corresponding to the left and right channels, create a stereo effect, enhancing the layering and spatial quality of the music. The acoustic cavity assembly 9 is secured to the screw posts of the middle shell 1 by screws. The screws pass through mounting holes on the acoustic cavity assembly 9 and are tightened into the screw posts of the middle shell 1, ensuring the stability of the acoustic cavity assembly 9 during use and preventing displacement due to vibration or other factors during equipment operation, which could affect the sound output.

[0053] In one possible embodiment, the device further includes a function button assembly 11 and an electronic display screen 12. The function button assembly 11 is provided with buttons and is electrically connected to the main control circuit board 8. The electronic display screen 12 is electrically connected to the main control circuit board 8 and is mounted on a rectangular area above the middle shell 1 to display the device's operating status.

[0054] Specifically, the buttons on the function button assembly 11 are the direct interface for user operation of the device. Microswitches and other triggering devices are connected below the buttons. When the user presses a button, the microswitch closes, the circuit is connected, and an electrical signal is generated. These electrical signals are transmitted to the main control circuit board 8 via wires. After receiving the signals, the main control circuit board 8 controls the corresponding functions of the device according to the preset program logic, such as play, pause, and volume adjustment. The electronic display screen 12 is electrically connected to the main control circuit board 8 and transmits data signals via a data cable. The main control circuit board 8 sends the device's operating status data, such as the track being played, playback progress, and volume level, to the electronic display screen 12 according to a specific communication protocol. The driver chip inside the electronic display screen 12 controls the brightness and color changes of pixels or display segments on the screen based on the received data, thereby displaying the device's operating status in real time, allowing the user to intuitively understand the device's status and improving operational convenience.

[0055] In one possible embodiment, a switch interface assembly 13 is also included, which includes a toggle switch, a charging indicator light, a Type-C interface, a USB interface, and a headphone jack; the toggle switch, the charging indicator light, the Type-C interface, the USB interface, and the headphone jack are all electrically connected to the main control circuit board 8; the toggle switch, the charging indicator light, the Type-C interface, the USB interface, and the headphone jack are respectively installed in the elliptical switch slot, the circular charging indicator light slot, the Type-C slot, the USB slot, and the circular headphone jack slot of the bottom shell 2.

[0056] See Figure 8 Specifically, the toggle switch allows users to easily control the device's on and off states. Its working principle involves manually toggling the switch's lever to change the on / off state of the internal circuitry. When the lever is in different positions, the corresponding circuit contacts are connected or disconnected, thereby controlling the power supply circuit and enabling the device to be turned on and off. The charging indicator light visually displays the battery's charging status and typically uses a light-emitting diode (LED). When the device is connected to a power source for charging, the main control circuit board 8 controls the current flow to the charging indicator light based on the battery's charging status. When the battery is charging, current flows through the LED, causing it to illuminate and display the charging status. When the battery is fully charged, the main control circuit board 8 stops supplying power to the charging indicator light, turning off the LED and allowing users to easily monitor the charging progress. The Type-C interface is used for battery charging. It adopts the universal Type-C standard, supports reversible insertion, and has high power transmission capabilities. During charging, external power is transmitted to the device's internal charging circuit through the Type-C interface. Under the control of the main control circuit board 8, the charging circuit manages the battery's charging, including controlling the charging current and voltage, ensuring safe and efficient charging.

[0057] The USB interface allows for audio file input and operates based on the USB communication protocol. When an external storage device (such as a USB flash drive) is connected to the device via the USB interface, the main control circuit board 8 identifies the storage device and reads the audio file data. According to the audio format supported by the device, the main control circuit board 8 decodes and processes the read data, transmitting the audio signal to the audio playback module for playback. The headphone jack serves as both headphone output and AUX input. When headphones are plugged into the headphone jack, the internal mechanical structure automatically switches the circuit connection, transmitting the audio signal from the device's internal audio output circuit to the headphones, driving them to produce sound. When an external audio device is connected via an AUX cable, the external audio signal is transmitted to the headphone jack via the AUX cable, then converted by the internal circuitry of the jack before being transmitted to the device's audio processing module for processing and playback. The precise fit between each interface and its corresponding slot on the bottom shell 2 ensures accurate installation and a compact structure. The shape and size of the slots precisely match the interface's shape. After the interface is installed in the slot, it is secured using snap-fit ​​and soldering methods to ensure it will not loosen during use and guarantees stable signal transmission.

[0058] In one possible embodiment, a battery compartment 14 is also included, which is adapted to and installed with the middle shell 1 and the bottom shell 2, and the battery compartment 14 is used to house a power supply battery to power the device.

[0059] Specifically, the battery compartment 14 provides a dedicated space for the power supply battery. Its installation with the middle shell 1 and bottom shell 2 is achieved through screw connections and snap-fit ​​connections. The battery compartment 14, the middle shell 1, and the bottom shell 2 are designed with corresponding mounting holes and snap-fit ​​structures. During installation, the battery compartment 14 is aligned and tightened with screws or snap-fits to ensure its stability within the device. The power supply battery provides power to the various components of the device through the battery compartment 14. The chemical substances inside the battery undergo a chemical reaction to generate electrical energy. This energy is transmitted through electrodes inside the battery compartment 14 to the device's power lines, supplying power to the main control circuit board 8, the core assembly 5, the LED light strip 6, and other components. This eliminates the device's dependence on an external power source, making it easier for users to operate the device in different scenarios and improving its flexibility and convenience.

[0060] The working principle of this utility model is as follows:

[0061] From an overall structural perspective, the device adopts a book-shaped flip-top design. The upper flip-top 3 and the middle shell 1 are connected by a steel pin to rotate, simulating the action of turning pages in a book. This not only enhances the uniqueness of the design and the user experience, but also makes it convenient for users to put in and take out CDs.

[0062] In terms of the core CD playback function, the CD tray 4 holds the CD and works in conjunction with the mechanism assembly 5. The mechanism assembly 5 consists of the mechanism and the mechanism tray. The mechanism is fixed on the mechanism tray. When a CD is placed on the CD tray 4 and engaged with the mechanism assembly 5, the laser head inside the mechanism emits a laser. By detecting the difference in light reflected from the pits and flat surfaces of the CD, the light signal is converted into an electrical signal. This electrical signal is transmitted to the main control circuit board 8, which integrates a DVD signal processing circuit. This circuit decodes the received electrical signal, amplifies the decoded audio signal through an audio amplification circuit, and then transmits the amplified signal to the sound cavity assembly 9. The sound cavity assembly 9 has two sets of rectangular plastic structural components, each housing a speaker. The speakers are connected to the main control circuit board 8 via red and black wires. Upon receiving the audio signal, the speakers vibrate and produce sound, thus amplifying the audio. The two sets of sound cavity assemblies 9 serve as the left and right channels, respectively, enhancing the sound quality. Meanwhile, the mechanism tray has three fan-shaped notch structure slots that hold three shock-absorbing silicone rubbers. The bottom of the silicone rubbers is connected to the structural column of the middle shell 1, which can reduce the shaking of the mechanism during operation, avoid skipping, and ensure playback stability.

[0063] The ambient lighting function is achieved by LED light strip 6, which consists of 15 LEDs and a flexible circuit board. Four structural limiters around the CD tray 4 secure the LED light strip 6 to the outer perimeter of the middle shell 1 tray. When the LED light strip 6 is in operation, the light emitted can pass through the annular slot in the center of the CD tray 4, creating different ambient effects and enriching the user experience.

[0064] In terms of power supply and control, the battery compartment 14 provides space for the power supply battery. The battery is fixed to the rear shell with screws through a perforated structural component, providing power to the various components. If the battery power is insufficient, it can be charged by connecting to the Type-C interface through the DC5V Type-C slot on the bottom shell 2. The charging indicator light illuminates during charging and turns off when fully charged. The power management circuit of the main control circuit board 8 is responsible for managing the power supplied by the battery, stabilizing the voltage, and distributing the current to the various components. The function button assembly 11 consists of a 7-button layout, an electronic display screen 12, and a circuit board. The buttons are electrically connected to the main control circuit board 8. Users can use the buttons to play, pause, and switch tracks. The electronic display screen 12 shows the current operating status of the device. The toggle switch in the switch interface assembly 13 is used to control the power on and off of the device. The USB interface can be used for audio file input, and the 3.5mm jack can be used to connect headphones as output or an AUX cable as input, further expanding the device's functionality.

[0065] Furthermore, the bottom shell 2 and the middle shell 1 are tightly connected by long strip protrusions on the top and left and right sides, as well as a protrusion and concave fastener in the middle of the bottom. The door-shaped protrusions on the left and right sides of the bottom shell 2 are fixed with screws, ensuring the stability of the overall structure of the equipment. The foot pads 10 at the bottom of the middle shell 1 are embedded in four cylindrical grooves and glued together, which can raise the product, increase friction, and prevent the equipment from shaking and scratching the outer surface during use.

[0066] The method of using this utility model is as follows:

[0067] (1) Equipment preparation: Before use, check whether the battery compartment 14 is installed. If the power is insufficient, connect the Type-C interface through the DC5V Type-C slot of the bottom shell 2 to charge the battery. At this time, the charging indicator light in the circular charging indicator light slot will light up. The indicator light will turn off after the battery is fully charged.

[0068] (2) Placing CD: Hold the top cover 3 to simulate the action of turning pages in a book, rotate around the steel needle to open the top cover 3, put the CD into the CD tray 4, ensure that the CD is placed stably, and then close the top cover 3.
