[0033] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0034] Please see Figure 1-4 The present invention relates to an ultra-wideband, springless loudspeaker, comprising the following components:
[0035] The basin frame 1 has a basin cavity inside, and the top of the basin frame 1 has an opening, with an installation edge 10 surrounding the inner side of the opening.
[0036] The cone 6 has a raised edge 11 around its top side, which is adapted to the mounting edge 10 of the frame 1. The cone 6 is provided with a diaphragm.
[0037] Conductor frame 2 is installed in the pelvic cavity. Conductor post 5 is provided on conductor frame 2. The top of conductor post 5 is surrounded by slot 14.
[0038] The magnet and the magnetic plate 4 each have an opening at their center, are mounted on the conductor frame 2, and the opening is adapted to the conductor post 5 to form a gap;
[0039] The voice coil 7 is inserted into the gap between the magnet and the magnetic plate 4, and the top of the voice coil 7 is in contact with the bottom of the cone 6.
[0040] The reinforcing ring 8 is inserted into the slot 14 at the top of the conductor post 5, with the top of the reinforcing ring 8 abutting against the bottom of the cone 6.
[0041] Cone 6 structural design:
[0042] The inner ring groove 12 and outer ring groove 13 designed at the bottom of the cone 6 are among the key technical features. The inner ring groove 12 is used to insert the reinforcing ring 8, which not only strengthens the structural rigidity of the cone 6 but also helps reduce the deformation of the cone 6 during vibration, thereby improving the stability and clarity of the sound. The outer ring groove 13 is used to insert the bottom of the voice coil 7, ensuring a tight contact between the voice coil 7 and the cone 6, so that the electromagnetic force generated by the voice coil 7 can be efficiently transmitted to the cone 6, driving it to vibrate and produce sound.
[0043] Fixed structure:
[0044] The fixing structure achieves a stable connection between the cone 6 and the frame 1 through the fixing holes 16 on the mounting edge 10 and the protruding edge 11, as well as the fixing bolts passing through them. This design ensures that the cone 6 will not shift or loosen during vibration, guaranteeing the stability and consistency of sound output.
[0045] Fasten mounting bolts and components:
[0046] The mounting holes 15 surrounding the conductor frame 2, magnet, magnetic guide plate 4, and cone 6, along with mounting bolts, securely fasten all components together. This fastening method not only improves the overall structural strength of the loudspeaker but also ensures the relative stability of the components, preventing noise and distortion caused by vibration.
[0047] Application of sound insulation pads:
[0048] Sound insulation pads are wrapped around the outer and inner surfaces of the speaker cone 6, effectively reducing sound reflection and leakage inside the speaker. This helps improve sound quality, making the sound purer and clearer, and reducing unnecessary noise and interference.
[0049] Window 9 Design:
[0050] The window 9, which surrounds the speaker frame 1 and communicates with the diaphragm cavity, alters the airflow path of the voice coil 7 acting on the frame 1. By optimizing the shape, size, and position of the window 9, the frequency response and sound directionality of the loudspeaker can be further improved, achieving ultra-wideband sound. The presence of the window 9 also promotes airflow inside and outside the frame 1, aiding in heat dissipation and reducing vibration damping of the frame 1, thereby improving the dynamic range and response speed of the sound.
[0051] Material selection:
[0052] Voice coil 7 and reinforcing coil 8 are made of copper. Copper has excellent electrical and thermal conductivity, ensuring that voice coil 7 generates sufficient electromagnetic force when energized, while quickly dissipating heat to maintain its stability and lifespan. Furthermore, copper's moderate density and hardness facilitate precise machining and installation of voice coil 7 and reinforcing coil 8.
[0053] The working principle of this ultra-wideband, springless loudspeaker mainly relies on its unique component combination and structural design. The following is a detailed summary of its working principle:
[0054] Component assembly and installation:
[0055] The frame 1 serves as the support structure for the entire speaker, and its interior contains a cone to house other key components. The top of the frame 1 has an opening, and the inner side of the opening is surrounded by a mounting edge 10 for fitting and fixing to the protruding edge 11 of the cone 6.
[0056] The cone 6 is a key component for sound production. It has a diaphragm that converts the vibrations generated by the voice coil 7 into sound waves. The convex edge 11 of the cone 6 fits tightly with the mounting edge 10 of the frame 1 to ensure the stability of the cone 6 during vibration.
[0057] The conductor frame 2 is installed inside the cone, and it has conductor posts 5 and slots 14. The conductor posts 5 provide support for the voice coil 7 and guide the vibration direction of the voice coil 7. The slots 14 are used to install the reinforcing coil 8 to further reinforce the connection between the cone 6 and the conductor frame 2.
[0058] A magnet and a magnetic plate 4 are mounted on a conductor frame 2, with a gap between them for the voice coil 7 to be inserted. The magnetic field generated by the magnet interacts with the current in the voice coil 7, producing an electromagnetic force that drives the voice coil 7 to vibrate within the gap.
[0059] Vibration and sound production process:
[0060] When the audio signal is transmitted through the wire to the conductor frame 2 and the conductor post 5, and then guided to the voice coil 7, the current in the voice coil 7 changes accordingly. Since the voice coil 7 is located in the gap between the magnet and the magnetic plate 4, the changing current will be subjected to a force in the magnetic field, thereby driving the voice coil 7 to vibrate up and down within the gap.
[0061] The vibration of the voice coil 7 is transmitted to the cone 6 through the tight fit between its top and the bottom of the cone 6. The cone 6 then vibrates, causing the diaphragm on it to generate sound waves. Due to the tight fit between the cone 6 and the frame 1, as well as the reinforcement effect of the reinforcing ring 8, the vibration of the cone 6 is stably and efficiently converted into sound wave output.
[0062] Ultra-wideband and waveless characteristics:
[0063] This speaker's design achieves an ultra-wide frequency response by optimizing the structure and combination of components such as the cone 6, conductor frame 2, magnet, and magnetic plate 4. Specifically, its low-frequency response extends to even lower frequencies, while its high-frequency extension is smoother and more natural, thus covering a wider audio range.
[0064] Furthermore, this speaker employs a spider-free design. While the spider structure in traditional speakers helps stabilize the vibrating unit to some extent, it also limits low-frequency response and sound quality. This speaker, however, replaces the spider's function with other structural designs (such as the reinforcing coil 8 and tight component fit), achieving a spider-free sound effect and further improving low-frequency response and sound quality.
[0065] In summary, the ultra-wideband, springless loudspeaker described in this patent document achieves efficient, stable, and pure ultra-wideband sound output through its unique component combination and structural design, and possesses springless characteristics.
[0066] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
