Description

Technical Field

[0001] The utility model relates to the technical field of loudspeakers, in particular to a double-tweeter loudspeaker with a dazzling color band. Background Art

[0002] A speaker is a transducer device that converts electrical signals into acoustic signals. Its performance significantly impacts sound quality. While the speaker is the weakest component in audio equipment, it is also the most crucial component for optimal sound quality. Speakers come in many varieties, and their prices vary widely. Audio electrical energy, through electromagnetic, piezoelectric, or electrostatic effects, causes the cone or diaphragm to vibrate, resonating with the surrounding air and producing sound.

[0003] Chinese patent CN201320012994.X discloses a loudspeaker with good sound quality, comprising a loudspeaker body, which is fixedly connected to a base by screws, and a fixed reinforcement ring is provided on the base; the beneficial effects of the utility model are: simple, practical, and convenient, and the provision of the fixed reinforcement ring makes the loudspeaker more stable, the sound clearer, and the sound quality better.

[0004] The above solution only adds a fixed reinforcement ring to reduce a part of the resonance to achieve the effect of improving the sound quality. The effect of improving the sound quality is poor and the degree of decoration is low. Utility Model Content

[0016] Figure 2 for Figure 1 A schematic diagram of the assembly structure of a double tweeter with a colorful ribbon.

[0017] Figure 3 for Figure 1 A schematic cross-sectional structural diagram of a dual tweeter with a colorful ribbon. DETAILED DESCRIPTION

[0018] The following is a further detailed description of specific embodiments of the present invention. It should be understood that the description of the embodiments of the present invention herein is not intended to limit the scope of protection of the present invention.

[0019] like Figures 1 to 3, which is a schematic structural diagram of a dual tweeter with a colorful ribbon provided by the present invention. The dual tweeter with a colorful ribbon includes a magnetic assembly 10 and a cone assembly 20 disposed on the magnetic assembly 10. It is conceivable that the dual tweeter with a colorful ribbon also includes other functional structures, such as wiring ports, magnetic conductors, etc., which are well known to those skilled in the art and will not be described in detail here.

[0020] The magnetic assembly 10 includes a T-iron 11, a magnet 12 mounted on the T-iron 11, and a Wentz 13 mounted on the T-iron 11 and resting on the end face of the magnet 12. The T-iron 11 has a disc-shaped outer profile, with a cylinder 111 protruding from its center, giving it a T-shaped cross-section. A voice coil bobbin 14 is mounted on the cylinder 111. The voice coil bobbin 14 is fitted with a clearance fit to the cylinder 111, and a voice coil 15 is wound around the outer wall of the voice coil bobbin 14.

[0021] The two end faces of the magnet 12 adhere to the T-iron 11 and the washer 13, forming a single unit, facilitating the subsequent connection between the washer 13 and the cone assembly 20. Both the magnet 12 and washer 13 are annular, with a gap between them and the cylinder 111, allowing one end of the voice coil bobbin 14 to pass through their central areas. This is because when powered, the voice coil 15 generates a magnetic force that interacts with the magnetic field of the magnet 12, causing the voice coil bobbin 14 to move axially along the cylinder 111. Therefore, space must be reserved for the voice coil bobbin 14 to move.

[0022] The speaker cone assembly 20 includes a basin frame 21 screwed on the Wentz 13, a damper 22 arranged in the basin frame 21, a paper cone 23 covered on the basin frame 21, a dust cover 24 arranged in the middle area of ​​the paper cone 23 and covering the voice coil frame 14, a pressure plate 25 fixed on the side of the basin frame 21, an equivalent device mounting frame 26 connected to the pressure plate 25 at both ends, and two tweeters 27 arranged at intervals in the equivalent device mounting frame 26.

[0023] The frame 21 includes a frame body 211 and a plurality of openings 212 provided on the frame body 211. The outer edge of the damper 22 abuts against the inner wall of the frame body 211 and can be secured by adhesive or other means. Space is also reserved in the central area of ​​the frame body 211 and the damper 22 to facilitate axial movement of the voice coil bobbin 14. The openings 212 can reduce resonance within the frame body 211, improve sound diffusion, and simultaneously achieve the goals of reducing weight and dissipating heat.

[0024] The edge of the paper cone 23 is secured to the frame body 211 by adhesive bonding or other means. The central region of the paper cone 23 is fitted over the voice coil bobbin 14 with a clearance fit. A dust cover 24 seals the hole extending into the central region of the paper cone 23 and, in conjunction with the damper 22, prevents dust and other debris from entering the voice coil 15.

[0025] The pressure plate 25 is fixedly arranged in a ring shape on the side of the basin frame 21, clamping the edge of the paper basin 23 therein to further fix the paper basin 23. The two ends of the equivalent device mounting frame 26 are connected to the pressure plate 25 as a whole. This is because the equivalent device mounting frame 26 is directly located in the vertical direction of the paper basin 23, and the integrated design can reduce the resonance generated when playing sound. It is conceivable that the equivalent device mounting frame 26 and the pressure plate 25 can also be designed to be split to facilitate subsequent replacement. At least one through hole 261 is provided at the connection between the equivalent device mounting frame 26 and the pressure plate 25 to reduce resonance and reduce weight.

[0026] The two tweeters 27 are spaced apart and arranged on the equivalent device mounting frame 26, and are located in the middle area of ​​the paper cone 23 in the vertical direction. The two tweeters 27 pass through and are embedded in the equivalent device mounting frame 26, making it easy to connect the bottom of the tweeter 27 to an external power supply.

[0027] The tweeter 27 is a component for high-frequency sound. Its primary function is to convert the high-frequency portion of the audio signal (typically mid-high to ultra-high frequencies, such as 2000Hz to 20kHz or higher) into sound. The presence of two tweeters 27 improves the speaker's sound pressure level and frequency response, enhancing musical detail and spatial perception, and improving sound field localization, thereby optimizing sound quality and coverage. The operating principle of these tweeters is well-known technology and will not be further described here.

[0028] Both tweeters 27 are surrounded by a light strip 28. These light strips contain color-changing LEDs and are connected to the speaker's signal processing unit (not shown). By analyzing the music signal and rhythm intensity, they synchronously control the lighting effects, changing colors with the music's rhythm and enhancing the speaker's overall aesthetics. The two light strips 28 can be connected in series to the speaker's current filter (not shown) to ensure proper operation.

[0029] Compared to the prior art, the dual tweeter speaker with a colorful ribbon provided by the present invention employs an equivalent device mounting bracket 26 mounted on the pressure plate 25, with two tweeter units 27 spaced apart on the equivalent device mounting bracket 26. The two tweeter units 27 enhance the speaker's playback quality. A light ribbon 28 is arranged around the two tweeter units 27, changing color according to the rhythm of the music, satisfying the demand for speaker decoration.

[0030] The above are only preferred embodiments of the present invention and are not intended to limit the scope of protection of the present invention. Any modifications, equivalent replacements or improvements within the spirit of the present invention are included in the scope of the claims of the present invention.
