Description

Technical Field

[0001] This utility model relates to the field of speaker technology, and in particular to a speaker in the shape of a doll. Background Technology

[0002] The basic structure of most common speaker products on the market usually consists of three core components: First, the outer shell, which serves as external protection and structural support. It not only needs to have good acoustic characteristics but also needs to support the overall aesthetic design of the product. Second, the sound-generating unit, which is the core component responsible for converting electrical signals into sound waves. Its performance directly determines the sound quality of the speaker. Finally, the electronic circuit board, which is the "brain" of the entire speaker, is responsible for processing audio signal input, power amplification, and the execution of various control commands.

[0003] In terms of internal structure, these three core components generally adopt a fixed assembly process, achieving permanent connections through mechanical snap-fits, screw fixation, or welding. While this design ensures the structural stability of the product, it also results in a lack of upgradeable or replaceable space between components. At the human-computer interaction level, current mainstream control solutions mainly rely on fixed physical buttons. Some high-end models integrate Hall effect sensors (for detecting the proximity of magnetic components), capacitive touch sensing modules (triggering commands through changes in human body capacitance), or photoelectric sensors (achieving control through light obstruction). However, these interaction methods all suffer from a fixed form; the button layout and sensor positions are determined at the factory, and users cannot customize them according to their usage habits.

[0004] While this technological approach ensures product reliability, it creates a significant conflict between aesthetic appeal and functional practicality. From a design aesthetic perspective, speakers, as visual elements in the home environment, need their appearance, materials, and color schemes to harmonize with modern interior design styles. However, existing products, in pursuing innovative designs, are often constrained by the layout requirements of fixed control components, necessitating the creation of holes for buttons on the casing or the installation of protruding sensor modules. These functional structures severely disrupt the overall aesthetic integrity of the product. Conversely, when designers attempt to create a minimalist design, they often sacrifice some user convenience, such as integrating control functions into a companion mobile app, requiring users to rely on additional devices for basic operations. This dilemma of "aesthetics yielding to function" or "function compromising with aesthetics" makes it difficult for existing speaker products to achieve a balance between visual appeal and ease of use, failing to fully meet the higher demands of contemporary consumers for a comprehensive product experience.

[0006] This utility model provides the following technical solution:

[0018] Compared with related technologies, the beneficial effects of this utility model are:

[0019] This utility model provides a doll-shaped speaker, which breaks through the traditional square and rigid appearance of speakers by innovatively designing the main structure of the speaker into a three-dimensional doll shape. Specifically, the product adopts a biomimetic design concept, transforming the speaker body into the body structure of a doll.

[0020] In actual use, users first need to connect the speaker to a power source. Then, through the speaker's external module, users can choose between wireless or wired connection to establish a data communication link with terminal devices such as smartphones, tablets, and laptops. After pairing, users only need to apply a slight force to the head cover located at the top of the speaker to cause it to flip along a preset hinge structure.

[0037] Combination Figure 1 , Figure 4 and Figure 5 As shown, an embodiment of the present invention provides a doll-shaped speaker, including a body 100, a sound-emitting unit 200, a control component 300, and a head cover 400.

[0038] The body 100 is in the shape of a doll; the sound-generating unit 200 is installed inside the body 100; the control component 300 is disposed inside the body 100 and is electrically connected to the sound-generating unit 200; the control component 300 includes an external module, a control switch 310, and a main board, the main board being electrically connected to the external module, the control switch 310, and the sound-generating unit 200 respectively, the control switch 310 being disposed on the head 110 of the body 100; a head cover 400 is disposed over the head 110 of the body 100, the head cover 400 being hinged to the head 110 via a hinge shaft 410, so that the head cover 400 can be flipped relative to the head 110; the flipping of the head cover 400 relative to the head 110 can trigger the control switch 310, thereby controlling the working state of the sound-generating unit 200 via a preset program in the main board.

[0039] The doll-shaped speaker provided in this embodiment innovatively designs its main structure into a three-dimensional doll shape, breaking away from the traditional square and rigid appearance of speakers. Specifically, the product adopts a biomimetic design concept, transforming the speaker's cabinet into the body of a doll. Through rounded contour lines, anthropomorphic proportions, and delicate surface treatment, the speaker presents the characteristics of a complete art piece even when not in use, significantly enhancing its aesthetic value as a home decoration.

[0040] In actual use, the user first needs to connect the speaker to a power source. Then, the user can establish a data communication link with terminal devices such as smartphones, tablets, and laptops via the speaker's external module, choosing either a wireless or wired connection. After pairing, the user only needs to apply a slight force to the head cover 400 located at the top of the speaker's head 110 to cause it to flip along a preset hinge structure. During this flipping process, the head cover 400 triggers the control switch 310, automatically executing the start / stop control command of the sound-emitting unit 200 and controlling its on / off state.

[0041] This innovative interactive design achieves optimization in three dimensions: First, by combining the control switch 310 with the anthropomorphic movements of the doll, the traditional button operation process is simplified, making the function triggering process more in line with the user's intuitive operating habits; Second, the flipping action of the head cover 400 component has been ergonomically optimized, allowing for operation with one hand; Third, since the control mechanism is completely hidden inside the shape structure, while maintaining the overall aesthetics of the product, it effectively avoids the accidental touch problems that may be caused by traditional exposed buttons, thus establishing a perfect balance between functional implementation and aesthetic presentation, significantly enhancing the user's enjoyment.

[0042] In some specific embodiments, there are two hinge shafts 410, which are symmetrically arranged on both sides of the head 110 to ensure the reliability and stability of the flipping of the head cover 400 relative to the head 110.

[0043] In some specific embodiments, the control component 300 further includes a control base 320, which is fixedly installed inside the head 110, and the control switch 310 is disposed on the control base 320; the hinge shaft 410 is fixedly connected to the head cover 400, and the end of the hinge shaft 410 passing through the head 110 is provided with a control cam 411 corresponding to the control switch 310. The hinge shaft 410 rotates relative to the control base 320, which can drive the control cam 411 to move, thereby contacting and pressing the control switch 310; when the user operates the head cover 400 to flip relative to the body 100, the hinge shaft 410 rotates accordingly, and the control cam 411 fixed at the end of the shaft rotates synchronously, and its working surface gradually approaches and finally contacts the trigger button of the control switch 310. This mechanical transmission mechanism has dual technical advantages: First, by utilizing the rigid transmission characteristics of the cam mechanism, the flipping motion of the head cover 400 is transformed into a linear pressing action on the control switch 310, effectively eliminating the contact problems that may occur in traditional flexible trigger structures; Second, by completely embedding the control switch 310 and transmission components within the enclosed cavity of the head 110, retaining only the necessary hinge shaft 410 mechanical interface, the product shell forms a complete protective barrier, providing better protection against liquid splashes, while significantly reducing the probability of accidental activation during daily use, thus significantly improving the overall reliability and environmental adaptability of the product.

[0044] In some specific embodiments, the control switch 310 uses a micro switch as the core triggering element. This micro switch is designed based on the deformation principle of a metal spring and contains a highly sensitive silver alloy contact group. When an external force reaches a threshold of 0.2N ± 0.05N, the contact group can complete the on / off switching within 0.5ms. The trigger response time is 60% shorter than that of traditional mechanical switches, and it maintains stable electrical performance after 50,000 life cycles. It has significant advantages such as high trigger sensitivity and strong resistance to mechanical fatigue. In particular, this micro switch uses a fully sealed resin potting process, achieving an IP67 protection rating, effectively resisting dust intrusion and short-term water immersion risks.

[0045] Of course, in other embodiments of this utility model, the control switch 310 can also adopt a non-contact sensing scheme to meet the needs of different application scenarios. For example, a rotating shaft Hall effect sensor switch integrates a neodymium iron boron permanent magnet at the end of the hinge shaft 410, and works with a linear Hall sensor (model AH49E) built into the control base 320. When the shaft rotates, the change rate of magnetic field strength exceeds 15mT / ° to trigger the switch signal output. This scheme has the characteristics of no wear, long life (theoretical life exceeding 1 million times), and vibration resistance reaches the 10G (10-2000Hz) standard. Another optional scheme is a rotating shaft photoelectric sensor switch, which adopts a through-beam infrared phototube structure. A light-transmitting groove is opened at a specific position of the hinge shaft 410. When the shaft rotates and aligns the light-transmitting groove with the transmitting / receiving tube, the change rate of light flux exceeds 70% to activate the switch state. This technical solution has a response delay of less than 1ms and is not affected by electromagnetic interference, making it particularly suitable for scenarios with high control precision requirements. The above alternatives, while maintaining basic functionality, expand the product's applicability by changing the triggering mechanism, allowing for flexible selection based on actual usage needs.

[0046] like Figure 6 As shown, in some specific embodiments, the control cam 411 has a protruding tube 412 at its end near the control seat 320. The control seat 320 has a movable groove 321 corresponding to the protruding tube 412. The protruding tube 412 passes through the movable groove 321, which restricts and guides the movement trajectory of the protruding tube 412. A limiting bead 413 is provided inside the protruding tube 412. An elastic element 414 is provided between the limiting bead 413 and the bottom of the protruding tube 412. The elastic element 414 can be a spring. The bottom of the movable groove 321 has multiple shift grooves 322 corresponding to the limiting bead 413. When the relative position of the head cover 400 and the body 100 changes, the limiting bead 413 can be pressed against the corresponding shift groove 322 under the elastic force of the elastic element 414.

[0047] When the user flips the head cover 400 relative to the torso 100 and head 110, the hinge shaft 410 drives the control cam 411 to rotate synchronously. At this time, the convex tube 412 slides within the movable groove 321. During the flipping process, the limiting bead 413 is compressed by the arc-shaped groove wall of the movable groove 321, thus compressing the spring. When the head cover 400 flips to a preset angle, the limiting bead 413 is precisely aligned with the corresponding position groove 322 and automatically engages in the position groove 322 under the action of the spring force, forming a clear tactile feedback. Through actual testing, it has been verified that this positioning mechanism has a certain holding torque at each position point, which can effectively resist the influence of external disturbances and ensure that the head cover 400 can maintain stable positioning at any flipping angle. This mechanical positioning design has dual technical benefits: on the one hand, the multi-point locking function greatly improves the accuracy of maintaining the relative position of the head cover 400 and the body 100, meeting the user's precise control needs for specific flip angles; on the other hand, when the head cover 400 is in the positioning state, the relative position of the control cam 411 and the micro switch remains constant, reducing the fluctuation range of the switch trigger pressure and significantly improving the reliability of the locking position of the control switch 310, ensuring that the product can maintain stable mechanical performance in different usage states such as play, pause, and volume adjustment.

[0048] like Figure 3 As shown, in some specific embodiments, the sound-emitting unit 200 is disposed within the head 110. The front face 111 area of ​​the head 110 adopts an array-type opening process, with multiple circular sound outlet holes 112 of Φ2.0mm in diameter evenly distributed. These sound outlet holes 112 are arranged in a 7×12 matrix, with the hole spacing controlled at 4.5mm, and the overall opening rate reaches 38%. This not only meets the technical requirements for speaker opening rate in the IEC 60268-5 standard, but also effectively suppresses high-frequency diffraction through the honeycomb arrangement structure. The head cover 400 can be flipped relative to the head 110 to cover the front face 111 of the head 110, preventing dust from entering the body 100 through the sound outlet 112. At the same time, this variable sound output structure design ensures the rationality of the product's sound output in different usage scenarios—the closed state is suitable for silent display as an environmental decoration, and the open state meets the needs of music playback. Through the dual effects of physical blocking and acoustic optimization, users can obtain a more natural interactive experience during operation, improving the unity of the product's practicality and aesthetic value.

[0049] In some specific embodiments, the lower end of the front face 111 of the head 110 is provided with lower teeth, and the head cover 400 is provided with upper teeth corresponding to the lower teeth. The flipping of the head cover 400 relative to the head 110 can be simulated as the opening and closing of the doll's mouth, which further improves the aesthetics of this embodiment and demonstrates the organic unity of function and aesthetics.

[0050] In some specific embodiments, a power supply unit is provided within the body 100, which is electrically connected to the sound-generating unit 200 and the control component 300 in sequence. The power supply unit specifically uses a polymer lithium-ion battery with an operating voltage range of 3.7V±0.1V, supports a maximum constant current charging of 1A, and is equipped with a triple circuit protection mechanism including overcharge protection, over-discharge protection, and short-circuit protection. The positive and negative output terminals of the power supply unit are electrically connected to the motherboard within the body 100 via tin-plated copper wires, ensuring the stability of the electrical connection. By integrating an independent power supply unit inside the body 100, this embodiment achieves mobile use capability without an external power source. This built-in power solution not only solves the problem of the constraints of traditional external power cables, allowing the product to be flexibly placed on desktops, bookshelves, or any other location, but also, through the intelligent sleep mechanism of the power management module (such as automatically entering a low-power mode after 10 minutes of inactivity), controls standby power consumption to below 0.5mW, significantly improving the product's portability and energy efficiency.

[0051] like Figure 2 As shown, in some specific embodiments, the body 100 is provided with a tail 120, which is connected to the power switch of the power supply unit. The tail 120 integrates a micro-mechanical transmission device, and its base is physically connected to the power control module inside the body 100 through a cross-shaped slot. The control module adopts a dual-channel design: the main channel is connected to the power supply unit's on / off control circuit, triggering the power switch through the axial pressing action of the tail 120 to achieve power on / off switching; the secondary channel is connected to the power adjustment circuit, driving the potentiometer to change the output voltage through the clockwise / counterclockwise rotation action of the tail 120, thereby adjusting the working power of the sound unit 200; in addition, it facilitates the concealment of the power switch, improving the overall aesthetics of this embodiment.

[0052] In some specific embodiments, the power supply unit has a charging interface 130, which is located on the side of the body 100 near the tail 120, making it easy to hide and improving the overall aesthetics of this embodiment.

[0053] In some specific embodiments, two ears 420 are symmetrically provided on the head cover 400, which makes it easier for the user to move the head cover 400 by holding the ears 420, thus improving the user comfort of this embodiment.

[0054] In some specific embodiments, the external module adopts a modular expansion design, with core components including a Bluetooth wireless communication module and a wiring harness connection module. These two components optimize the product form through structural reuse and functional integration. Specifically, the Bluetooth module uses a low-power chip (model nRF52840) compliant with the Bluetooth 5.3 standard, supporting audio transmission protocols such as A2DP and AVRCP. Its antenna uses a PCB-on-board design, with an effective radiation area controlled within the range of 25×8mm, ensuring a long effective transmission distance (measured in an open environment) while reducing electromagnetic interference to below -65dBm through a metal shield (0.2mm thick). This module communicates with the main control chip via an SPI interface. Upon first use, the user only needs to press and hold the function button on the back of the device for several seconds to enter pairing mode and record device pairing, ensuring rapid identification and connection in multi-device environments.

[0055] To accommodate traditional wired connection needs, the external module also integrates wired transmission functionality. Its wiring harness connection module adopts a composite interface design shared with the charging interface 130. This design fully integrates the wiring harness interface and the charging interface 130, with the surface flatness of the interface area controlled within ±0.05mm. Combined with the 0.3mm chamfering around the interface, it avoids the structural protrusions caused by traditional dual-interface layouts and achieves triple functions of "charging + wired audio + data transmission" through a single interface.

[0056] Through the modular design described above, this embodiment provides a flexible connection solution while maintaining a simple appearance: users can freely choose between wireless or wired connection methods according to the usage scenario, and the two modes can be automatically switched via a hardware switch (when a wired signal input is detected, the Bluetooth module automatically enters a sleep state), making this embodiment applicable to more usage scenarios.
