Description

Technical Field

[0001] This utility model relates to the field of loudspeaker technology, and in particular to a loudspeaker specifically for headphones. Background Technology

[0002] Headphone-specific speakers are miniature sound-generating units specifically designed for the acoustic scenarios, wearing methods, and sound quality requirements of headphones. They are not simply miniaturized versions of general-purpose speakers (such as speaker cabinets). They must achieve wide frequency response, low distortion, and adaptation to the auricular sound field within constraints of small size, close-range listening, and low power consumption. They are the core component for the sound quality performance of headphones.

[0003] Existing dedicated loudspeakers for headphones mainly consist of a diaphragm, centering support, frame, voice coil, and auxiliary mounting components. During long-term use, the diaphragm is prone to collapse. This is partly due to the diaphragm material itself potentially having insufficient fatigue resistance; repeated stretching from sound wave vibrations over extended periods causes it to gradually lose elasticity. Current methods for repairing loudspeaker diaphragms typically involve using tape to adhere the diaphragm, leveraging the tape's adhesive properties to pull and press the dented area back together, thus attempting to repair it as much as possible. However, since existing loudspeakers are secured to auxiliary mounting components with multiple sets of screws, disassembly requires external tools such as screwdrivers, making the process inconvenient. Therefore, a dedicated loudspeaker for headphones is needed.

[0004] It should be noted that the information disclosed in this background section is only for understanding the background technology of this application concept, and therefore may include information that does not constitute prior art. Utility Model Content

[0005] This utility model provides a dedicated speaker for headphones to solve the problem that existing headphone speakers contain components such as diaphragms, and the diaphragms are prone to collapse due to poor fatigue resistance and long-term vibration. Repairing them usually involves sticking them with tape, but disassembling and repairing the speakers requires inconvenient tools.

[0006] The present invention adopts the following technical solution: a speaker for headphones, mainly comprising a speaker assembly, the speaker assembly including a mounting panel, a frame integrally provided on the bottom surface of the mounting panel, a voice coil provided on the frame, and a diaphragm provided on the voice coil; a mounting component disposed at the lower end of the speaker assembly, the mounting component including a mounting part, the mounting part including a mounting base adapted to the shape of the headphone ear shell; and a fixing component adapted to be mounted on the mounting panel and the mounting base, the fixing component including a guide part disposed on the mounting base and used to guide the installation of the speaker assembly on the mounting component; the mounting panel is provided with two sets of docking parts for providing a basic connection for locking the speaker assembly and the mounting component, and the docking parts are provided with a tightening part for locking the speaker assembly and the mounting component.

[0007] Furthermore, the docking part includes a plug rod that passes through and is fixed on the mounting panel. The bottom surface of the plug rod has an opening groove. A locking rod that is adapted to be inserted into the mounting base plate is fixed through and is fixed. The top surface of the locking rod is open. A step is provided at the opening position of the locking rod to provide limiting support for the plug rod.

[0008] Furthermore, the tightening part includes a threaded sleeve that passes through and is fixed to the top of the insert rod. A screw is threadedly connected to the threaded sleeve, and a threaded groove is opened at the corresponding position of the threaded sleeve. A sliding member is fixed to one end surface of the screw. A guide arc block adapted to the sliding of the sliding member is integrally provided on the inner wall of the locking rod. The contact surface between the guide arc block and the sliding member is set at a slope. The slope design converts the rotational movement of the screw into the axial displacement of the sliding member. The contact surface between the sliding member and the guide arc block is set at an inclination.

[0009] Furthermore, one end surface of the screw is fixed with an abutment member symmetrically arranged with the sliding member, and the inner wall of the locking rod is integrally provided with a pressing arc block suitable for contacting the upper surface of the abutment member. The bottom surface of the pressing arc block has a flexible anti-slip pad, which is used to increase the friction between the abutment member and the pressing arc block.

[0010] Furthermore, a knob is fixed to one end of the screw.

[0011] Furthermore, the locking rod has symmetrically arranged positioning pins on its inner wall near the opening, and the corresponding position on the surface of the insertion rod has a pin groove adapted to the positioning pin.

[0012] Furthermore, a positioning block is sleeved on one end of the screw near the upper end of the insert rod, and the positioning block serves to limit the movement.

[0013] Furthermore, the guide portion includes two sets of obliquely symmetrically arranged positioning rods that pass through and are fixed on the mounting base plate, and sleeves suitable for fitting onto the positioning rods are fixed through and at two opposite corners of the mounting panel.

[0014] Furthermore, the mounting base plate has an annular protrusion extending upward, and the mounting base plate has a mounting cavity at its center adapted to the mounting of the speaker frame. A dustproof part is sleeved on the protrusion, and the dustproof part includes a fixing ring that engages with the protrusion and has an annular structure. The fixing ring is connected to the protrusion by fasteners, and the fixing ring has a filter screen for dust prevention of the speaker assembly.

[0015] The above-mentioned technical solutions adopted in the embodiments of this utility model can achieve the following beneficial effects:

[0016] This headphone-specific speaker utilizes a combination of guide, docking, and tightening parts in its mounting components, replacing the traditional multi-screw fixing method. The positioning rods and sleeves in the guide part allow for quick alignment of the speaker assembly with the mounting components, while the insertion and locking rods in the docking part provide a stable foundation connection. The tightening part allows for locking or unlocking simply by manually rotating a knob, eliminating the need for external tools such as screwdrivers and simplifying the disassembly of the speaker assembly. When the diaphragm collapses due to insufficient material fatigue resistance or loss of elasticity from prolonged sound wave vibration, users can easily disassemble the speaker assembly to repair the diaphragm, avoiding the tedious operation of removing screws. This improves the convenience of speaker maintenance and extends its service life, better meeting the maintenance needs of headphones during long-term use. Attached Figure Description

[0026] To further illustrate the technical means and effects adopted by this utility model in order to achieve the intended utility model purpose, the following detailed description of the specific implementation methods, structure, features and effects of this utility model is provided in conjunction with the accompanying drawings and preferred embodiments.

[0027] The technical solutions provided by the various embodiments of this utility model are described in detail below with reference to the accompanying drawings.

[0028] Reference Figures 1-3 As shown in the figure, the headphone-specific speaker provided in this embodiment of the present invention includes a speaker assembly 1, which includes a mounting panel 11. The mounting panel 11 provides a stable mounting base for the entire speaker, facilitating assembly with components such as the ear shell of the headphone. A frame 12 is integrally provided on the bottom surface of the mounting panel 11, and a voice coil 13 is provided on the frame 12. A diaphragm 14 is provided on the voice coil 13. The voice coil 13 is an electroacoustic conversion component. When an audio electrical signal passes through the voice coil 13, the voice coil 13 generates an electromagnetic force in the magnetic field, thereby driving the diaphragm 14 to vibrate and produce sound. At the same time, a central hole 16 is provided in the center of the voice coil 13. The central hole 16 can be combined with structures such as a phase cone to optimize the propagation path and diffusion effect of sound waves, allowing the headphone to create a more uniform and natural sound field when listening in the near field, thus improving the user's listening experience.

[0029] Reference Figure 2 As shown, a mounting component 2 is provided at the lower end of the speaker assembly 1. This mounting component 2 is used to assist in installing the speaker assembly 1 into the ear shell of the headphones. In actual use, the ear shell is a key structure for headphones to fit close to the human ear. The fitting installation of the mounting component 2 with the ear shell ensures that the speaker is stable and in the sound-emitting position, ensuring sound quality transmission. The mounting component 2 includes a mounting part, which includes a mounting base plate 21 adapted to the shape of the headphone ear shell. Its design fits the internal space of the ear shell, making installation more convenient and stable. An annular protrusion 22 extends upward on the mounting base plate 21, and a mounting cavity 23 adapted to the mounting of the frame 12 is located at the center of the mounting base plate 21. The mounting cavity 23 can accommodate the frame 12, ensuring the accurate relative position of each sound-emitting component of the speaker assembly 1, which is beneficial to the performance of acoustics.

[0030] Furthermore, a dustproof part is fitted onto the protrusion 22. The dustproof part includes a fixing ring 24 that is engaged with the protrusion 22 and has an annular structure. The fixing ring 24 is connected to the protrusion 22 by fasteners, and the fixing ring 24 has a filter 241 for dustproofing the speaker assembly 1. At the same time, a bracket 17 for supporting the filter 241 is fixed on the mounting panel 11. The filter 241 can effectively block external dust and impurities from entering the speaker assembly 1, preventing dust from adhering to key components such as the diaphragm 14 and voice coil 13 and affecting the sound output, thus extending the service life of the speaker. At the same time, it does not hinder the normal propagation of sound waves and ensures the sound quality performance of the headphones.

[0031] Reference Figures 2-5 As shown, a fixing component 3 is adapted to be installed between the mounting panel 11 and the mounting base plate 21. The fixing component 3 is used to fix the speaker component 1 on the mounting component 2. The fixing component 3 includes a guide portion provided on the mounting base plate 21. The guide portion includes two sets of obliquely symmetrically arranged positioning rods 32 that are fixed through the mounting base plate 21. At the same time, sleeve rods 31 suitable for sleeved on the positioning rods 32 are fixed through the two opposite corners of the mounting panel 11.

[0032] The mounting panel 11 is provided with two sets of docking parts, which are fixed through the mounting panel 11 at two other opposite corners. Each docking part includes a rod 36 fixed through the mounting panel 11. The bottom surface of the rod 36 is provided with an opening groove (not shown in the figure). A locking rod 33 that is adapted to be inserted into the mounting base plate 21 is fixed through the mounting base plate 21. The top surface of the locking rod 33 is open, and a step is provided at the opening position of the locking rod 33. The step design can provide limiting support when the rod 36 is inserted, so as to avoid the rod 36 being over-inserted and affecting the subsequent locking structure. The step is suitable for contacting one end of the rod 36.

[0033] Furthermore, a tightening part is provided through the top of the insertion rod 36. This tightening part is the key interactive structure for manual locking. The tightening part includes a threaded sleeve 361 that is fixed through the top of the insertion rod 36. A screw 371 is threaded through the threaded sleeve 361. A threaded groove (not shown in the figure) is provided at the corresponding position of the threaded sleeve 361. A sliding member 38 is fixed to one end surface of the screw 371. A guide arc block 34 adapted to the sliding member 38 is integrally provided on the inner wall of the locking rod 33. The contact surface between the guide arc block 34 and the sliding member 38 is sloped. This sloped design converts the rotational movement of the screw 371 into the axial displacement of the sliding member 38. The contact surface between the sliding member 38 and the guide arc block 34 is inclined.

[0034] Meanwhile, abutment 39 symmetrically arranged with sliding member 38 is fixed on one end surface of screw 371, and a pressing arc block 35 suitable for contacting the upper surface of abutment 39 is integrally provided on the inner wall of locking rod 33. The pressing arc block 35 is a component that achieves frictional fastening when locking, and the bottom surface of the pressing arc block 35 has a flexible anti-slip pad. The flexible anti-slip pad can increase the friction between abutment 39 and pressing arc block 35, improve the stability of locking, and avoid wear of components caused by hard contact. A knob 37 is fixed on one end of screw 371. The design of knob 37 conforms to ergonomics, making it convenient for users to manually tighten without the need for external tools, thus improving the ease of installation. A positioning pin block (not shown in the figure) is symmetrically arranged on the inner wall of locking rod 33 near the opening, and a pin groove adapted to the positioning pin block is opened at the corresponding position on the surface of insertion rod 36.

[0035] In this application, a positioning block is sleeved on one end of the screw 371 near the upper end of the insertion rod 36. The positioning block plays a limiting role. The positioning block is adapted to contact the top of the inner wall of the opening groove to limit the rotation of the screw 371, so that the sliding member 38 and the abutment member 39 on the screw 371 are initially in a fixed position.

[0036] It should be noted that when the speaker assembly 1 needs to be fixed on the mounting assembly 2, the mounting panel 11 is sleeved onto the positioning rod 32 via the sleeve rod 31, the insertion rod 36 is inserted into the locking rod 33, and the positioning pin is matched with the pin groove. At this time, the sliding member 38 at one end of the screw 371 is in contact with the high point of the ramp on the guide arc block 34, and the abutment member 39 is in the position of pressing the arc block 35. When the screw 371 is tightened, the sliding member 38 slides along the guide arc block 34 from the highest point. When sliding to the lowest point, this sliding process is guided by the ramp, driving the abutment 39 to approach the pressing arc block 35. Simultaneously, the upper end face of the abutment 39 contacts and presses the flexible anti-slip pad on the lower end face of the pressing arc block 35 until the knob 37 contacts the top of the threaded sleeve 361. The contact pressing friction between the upper end face of the abutment 39 and the flexible anti-slip pad achieves locking, which not only ensures the stability of the connection, but also allows for easy unlocking by turning the knob 37 in the opposite direction when disassembly is required. The operation is very convenient.

[0037] Working principle: When it is necessary to fix the speaker assembly 1 to the mounting assembly 2, the guide part of the fixing assembly 3 is used for initial positioning. The sleeve 31 on the mounting panel 11 will be sleeved on the positioning rod 32 on the mounting base plate 21. At the same time, the insertion rod 36 on the mounting panel 11 will be inserted into the locking rod 33 on the mounting base plate 21. The pin groove on the surface of the insertion rod 36 and the positioning pin block on the inner wall of the locking rod 33 are mutually adapted to each other, further ensuring the accuracy of the insertion of the insertion rod 36. At this time, the sliding part 38 at one end of the screw 371 is attached to the high point of the ramp on the guide arc block 34, and the abutment part 39 is located on one side of the pressing arc block 35, preparing for subsequent tightening and locking.

[0038] Next, the tightening and locking operation is performed by manually rotating knob 37, causing screw 371 to rotate within threaded sleeve 361. Since the contact surface between guide block 34 and slider 38 is sloped, as screw 371 rotates, slider 38 slides along the slope of guide block 34 from its highest point to its lowest point. During this process, abutment 39, symmetrically positioned with slider 38, gradually approaches pressing block 35, and the upper surface of abutment 39 contacts and presses against the flexible anti-slip pad on the lower surface of pressing block 35. As knob 37 continues to rotate until it contacts the top of threaded sleeve 361, the pressure between abutment 39 and flexible anti-slip pad reaches a sufficiently high level. Through the contact and pressure friction between the two, a stable lock is achieved between speaker assembly 1 and mounting assembly 2. When disassembly is required, simply turn the knob 37 in the opposite direction to allow the sliding member 38 to slide back to the high point along the ramp of the guide block 34, releasing the pressure between the abutment member 39 and the pressing block 35, and the speaker assembly 1 can be easily removed from the mounting assembly 2.

[0039] The above description is merely a preferred embodiment of the present utility model and is not intended to limit the present utility model in any way. Although the present utility model has been disclosed above with reference to a preferred embodiment, it is not intended to limit the present utility model. Any person skilled in the art can make some modifications or alterations to the above-disclosed technical content to create equivalent embodiments without departing from the scope of the present utility model. Any simple modifications, equivalent changes and alterations made to the above embodiments based on the technical essence of the present utility model without departing from the scope of the present utility model shall still fall within the scope of the present utility model.
