Description

Technical Field

[0001] This utility model relates to a low-frequency vibrator horn, specifically a vehicle-mounted low-frequency vibrator horn. Background Technology

[0002] In the field of automotive audio equipment, the performance and installation compatibility of automotive subwoofers have always been a key focus of the industry. Currently, most automotive subwoofers on the market have significant drawbacks in actual use: due to poor sealing of the mounting cavity, low-frequency sound waves are easily lost during propagation, resulting in a significant loss of low-frequency audio signals and ultimately weak low-frequency effects, failing to meet users' demands for a powerful bass experience. Meanwhile, using large-diameter subwoofers to enhance low-frequency effects presents new challenges—these speakers are bulky, poorly suited to the interior space of a vehicle, and excessively heavy, making installation cumbersome and potentially damaging to the vehicle's original structure, greatly limiting their application in automotive settings.

[0003] In addition, the working principle of traditional loudspeakers relies entirely on the transmission of sound waves in the air and the perception of sound through the human ear. Existing vibrating loudspeakers still have shortcomings in structural design and performance optimization, making it difficult to fully utilize the advantages of vibration transmission.

[0025] The following is in conjunction with the appendix Figure 1-3 The specific embodiments of this utility model will be described in further detail.

[0026] Example 1, by Figure 1-3 This utility model provides a vehicle-mounted low-frequency vibrator speaker, comprising an aluminum upper shell 1, a voice coil 2, a washer 3, a metal spring 4, a magnet 5, a T-iron 6, and a plastic lower shell 7.

[0027] Aluminum upper shell 1, used to fix voice coil 2 and form an overall structural frame;

[0028] Voice coil 2 is located in the middle of the aluminum upper shell 1 and is used to receive electrical signals and generate alternating current.

[0029] The magnetic circuit system includes a washer 3, a magnet 5 and a T-iron 6 connected in sequence, and the magnetic circuit system is fixed in the plastic lower shell 7 by a metal spring 4;

[0030] The plastic lower shell 7 is connected to the aluminum upper shell 1 and is used to fix the magnetic circuit system together with the aluminum shell 1 with the voice coil, so that the voice coil is positioned exactly in the gap of the magnetic circuit system.

[0031] The voice coil 2 interacts with the magnetic circuit system, driving the magnetic circuit assembly to vibrate axially, and the vibration is transmitted to the external mounting carrier through the plastic lower shell 7.

[0032] Aluminum upper shell 1: It is an important component of the overall structural frame. Its main function is to fix the voice coil 2, provide a stable mounting position for the voice coil 2, ensure that the voice coil 2 remains stable during operation, and also provide structural support for the entire vibrator speaker.

[0033] Voice coil 2: Located in the middle of the aluminum upper shell 1, it is a key component that converts electrical signals into vibrations. It can receive externally input electrical signals and generate alternating current, thereby interacting with the magnetic circuit system.

[0034] Magnetic circuit assembly: Composed of washer 3, magnet 5 and T-iron 6 connected in sequence. The magnetic circuit system is fixed in the plastic lower shell 7 by metal spring 4. The magnetic circuit system interacts with voice coil 2. Under the influence of the alternating current generated by voice coil 2, the magnetic circuit system is driven to vibrate axially.

[0035] Metal spring 4: This is a ring-shaped elastic structure. Its outer edge is fixed to the inner wall of the plastic lower shell 7, and its inner edge is connected to the magnet 5. It provides elastic support for the magnetic circuit system, ensuring that the magnetic circuit system can move stably and flexibly during vibration. The edge of the metal spring 4 is provided with multiple mounting holes for easy installation and fixation to the lower shell 7.

[0036] Plastic lower shell 7: Detachably connected to aluminum upper shell 1 via clips or screws, together forming a vibration cavity. It encapsulates the voice coil 2 and magnetic circuit system, protecting the internal components. Simultaneously, the plastic lower shell 7 secures the magnetic circuit system.

[0037] T-Iron 6: As part of the magnetic circuit assembly, it is bonded with magnet 5 and washer 3 with glue to form a magnetic circuit system that provides a fixed magnetic field.

[0038] Working Principle: When this invention is in use, the voice coil 2 receives an electrical signal and generates an alternating current. According to the principle of electromagnetic induction, the alternating current generates a changing magnetic field around the voice coil 2. At this time, the magnetic field generated by the voice coil 2 interacts with the fixed magnetic field in the magnetic circuit system (composed of the washer 3, magnet 5, and T-iron 6 connected in sequence), generating an electromagnetic force. Driven by the electromagnetic force, the magnetic circuit system vibrates axially.

[0039] The metal spring 4 is a ring-shaped elastic structure. Its outer edge is fixed to the inner wall of the plastic lower shell 7, and its inner edge is connected to the magnet 5, providing elastic support for the magnetic circuit system and enabling the magnetic circuit system to reciprocate stably. The vibration of the magnetic circuit system is transmitted to the external mounting carrier through the plastic lower shell 7, ensuring the effective transmission of vibration energy. This process converts electrical signals into low-frequency vibrations, providing users with tactile feedback and a richer audio experience.

[0040] Beneficial effects: Highly efficient vibration conversion: The interaction between the voice coil 2 and the magnetic circuit system (washer 3, magnet 5 and T iron 6) efficiently converts electrical signals into low-frequency vibrations based on the principle of electromagnetic induction, bringing users immersive tactile feedback and a rich audio experience.

[0041] Stable vibration performance: The unique ring-shaped elastic structure of the metal spring 4 has its outer edge fixed to the inner wall of the plastic lower shell 7 and its inner edge connected to the magnet 5, providing elastic support for the magnetic circuit system and ensuring that the magnetic circuit system maintains stable reciprocating motion during vibration, thus ensuring the consistency and reliability of the vibration effect.

[0042] Effective vibration transmission: The vibrator, with its plastic lower shell and aluminum upper shell locked together, can directly contact the external mounting carrier, enabling the vibration energy generated by the magnetic circuit system to be efficiently and directly transmitted to the mounting carrier such as the vehicle seat, thus enhancing the vibration effect.

[0043] Easy installation and maintenance: The aluminum upper shell 1 and the plastic lower shell 7 are detachably connected by clips or screws, which facilitates the encapsulation and protection of the internal components of the product and makes it easy to disassemble during installation and maintenance; the mounting interface at the bottom of the plastic lower shell 7 makes it easy to fix the product to the bottom or back of the vehicle seat, and the installation process is simple and quick.
