Description

Technical Field

[0001] This invention relates to the field of audio technology, and in particular to a vibration-suppressing loudspeaker. Background Technology

[0002] A loudspeaker is an audio device that converts electrical signals into sound by vibrating a cone, which in turn vibrates the air. This type of loudspeaker is also called an amplifier or a loudspeaker. A loudspeaker whose cone is placed directly in the air is called a radiating loudspeaker. Direct radiating loudspeakers are typically cone-shaped loudspeakers used in stereo radios, although some use metal cones. These loudspeakers are used in televisions, built into electronic instruments such as audio equipment, or in external devices such as vehicles, serving as audio equipment.

[0003] Existing loudspeakers typically consist of a frame, a magnetic circuit that generates a magnetic field, and a sound-generating part above the magnetic circuit. The magnetic circuit and sound-generating part are mounted on the frame, which is then mounted onto electronic devices or vehicles. In vehicles, the speaker frame is mounted on the vehicle's sheet metal, and the speaker's vibrations are transmitted to the sheet metal through the frame, causing unwanted vibrations. To address this, traditional technology uses complex structures to reduce the vibrations transmitted to the vehicle's sheet metal. However, this structure results in more parts, increased production costs, increased assembly work, and low production efficiency. Summary of the Invention

[0004] To address the aforementioned problems, this invention proposes a vibration-suppressing loudspeaker to reduce vibration, simplify the structure, lower production costs, and improve production efficiency.

[0005] To achieve the above objectives, the present invention provides a vibration-suppressing loudspeaker, comprising a frame, a sound-generating part, and a magnetic circuit part for forming a magnetic circuit. Both the magnetic circuit part and the sound-generating part are mounted on the frame, with the sound-generating part above the magnetic circuit part. The loudspeaker is characterized by further comprising a vibration buffer and a mounting frame located below the frame. The vibration buffer is situated between the frame and the mounting frame and is connected to both. The vibration buffer is elastic and is used to buffer the vibration of the frame before transmitting it to the mounting frame.

[0006] The vibration suppression speaker provided by this invention transmits the vibration of the speaker frame to the vibration buffer, which then buffers and reduces the transmitted vibration before transmitting it to the mounting frame, greatly reducing the vibration of the mounting frame and achieving a significant vibration suppression effect. The vibration buffer directly connects the speaker frame and the mounting frame, resulting in a very simple structure, reducing assembly work, lowering production costs, and improving production efficiency.

[0008] The present invention will now be described in further detail with reference to the accompanying drawings. Detailed Implementation

[0009] This invention relates to a vibration-suppressing speaker used to generate sound, which can be embedded in audio equipment such as televisions and automobiles for use as a sound system. See also... Figures 1 to 3 The vibration-damping loudspeaker includes a frame 2, a magnetic circuit section 3, a sound-generating section 4, a mounting bracket 5, a vibration damper 6, a spring 7, and a surround 8. The frame 2 is the main structural component of the vibration-damping loudspeaker of this invention, used to mount the various components and provide support. The frame 2 includes an upper frame 21, a lower frame 22, and a middle frame 23. The middle frame 23 is located between the upper frame 21 and the lower frame 22 and connects them. The upper frame 21, lower frame 22, and middle frame 23 can be integrally injection molded. The magnetic circuit section 3 is mainly used to form the magnetic circuit and is installed at the lower end of the lower frame 22. See also... Figure 4 The magnetic circuit section 3 includes a magnet 31, a lower clamping plate 32, and an upper clamping plate 33. The magnet 31 provides the magnetic field, and together with the upper and lower clamping plates 32, they form a magnetic circuit that determines the magnetic field strength of the loudspeaker. The sound-generating section 4 is mounted on the frame 2, above the magnetic circuit section 3, and includes a voice coil 41 and a cone 42, with the upper part of the voice coil 41 connected to the lower part of the cone 42. A portion of the voice coil 41 is inserted into the gap G in the magnetic circuit section 3 but does not contact the magnetic circuit section 3. A spider 7 is connected to both the voice coil 41 and the lower frame 22, and can buffer the vibration generated by the voice coil 41, thereby reducing the vibration transmitted to the lower frame 22. A surround 8 is connected to both the upper part of the cone 42 and the upper frame 21, and can buffer the vibration generated by the cone 42, thereby reducing the vibration transmitted to the upper frame 21. The sound-generating part 4 is mounted to the frame 2 via a spider 7 and a surround 8. The spider 7 and surround 8 also buffer the vibrations transmitted from the sound-generating part 4 to the frame 2. A dust cover 2a is located above the through-hole in the center of the cone 42 to prevent foreign objects from entering the speaker. Other components of the speaker are arranged inside the frame 2. When the power is applied, the voice coil 41 interacts with the aforementioned magnetic field, moving along... Figure 4The shaft A shown vibrates up and down, thereby driving the cone 42 to vibrate and produce sound.

[0010] See Figure 3 The upper part of the frame 2, below the frame 21, is provided with a vibration damper 6 and a mounting bracket 5. The vibration damper 6 is located between the upper frame 21 and the mounting bracket 5, and is connected to both the upper frame 21 and the mounting bracket 5. The entire vibration damping speaker is mounted on an external device via the mounting bracket 5, such as on a car door panel, thereby mounting the vibration damping speaker onto the vehicle.

[0011] The vibration damper 6 is used to buffer the vibration of the basin frame 2 before transmitting it to the mounting frame 5. It is a component that buffers the vibration generated by the sound-generating part 4 and is made of rubber or other elastic materials. In this embodiment, the vibration damper 6 is made of rubber. See also Figures 5 to 7 The vibration buffer 6 is generally annular, including a buffer body 60, an upper fixing protrusion 631, and a lower fixing protrusion 632. The buffer body 60 connects the upper fixing protrusion 631 and the lower fixing protrusion 632, which are located above and below the buffer body 60, respectively. The buffer body 60, the upper fixing protrusion 631, and the lower fixing protrusion 632 are all annular and coaxial. The upper basin frame 21 is provided with an annular upper fixing groove 24. The opening of the upper fixing groove 24 faces downward, and its shape is adapted to the upper fixing protrusion 631. Its size can be slightly smaller than that of the upper fixing protrusion 631. The upper fixing protrusion 631 is inserted into and tightly locked in the upper fixing groove 24 through elastic deformation, thereby installing the vibration buffer 6 onto the basin frame 2. The installation is secure and convenient. The mounting bracket 5 has a circular lower fixing groove 51 with its opening facing upwards. The groove's shape matches the lower fixing protrusion 632, but its size can be slightly smaller. The lower fixing protrusion 632 is elastically inserted into and tightly locked into the lower fixing groove 51, thus installing the vibration buffer 6 onto the mounting bracket 5. The installation is secure and convenient. The upper basin frame 21 is placed on the upper side of the vibration buffer 6. Figure 7 The mounting bracket 5 is placed below the vibration buffer 6 (in the Z-axis direction), and both the upper basin frame 21 and the mounting bracket 5 provide fixing force for the vibration buffer 6. The lower part of the mounting bracket 5 and the lower basin frame 22 are approximately at the same height (in the Z-axis direction). This structure prevents the vibration buffer 6 from detaching from the basin frame 21 or the mounting bracket 5. In this invention, a single component, the vibration buffer 6, connects the basin frame 2 and the mounting bracket 5. The vibration of the basin frame is transmitted to the vibration buffer, which first buffers and reduces the transmitted vibration before transmitting it to the mounting bracket, greatly reducing the vibration of the mounting bracket.

[0012] The buffer body 60 is used to buffer the vibration transmitted from the basin frame 2, and is located on the outer sides of the upper fixed protrusion 631 and the lower fixed protrusion 632. The middle part of the buffer body 60 protrudes outward in an arc shape, forming a buffer groove 61 located on the inner side. The curvature of the buffer body 60 is determined by the size of the buffer groove 61. The outer surface 60a is the outer curved surface of the buffer body 60, and the inner surface 60b is the inner wall surface of the buffer body 60. When the buffer body 60 receives the vibration transmitted from the basin frame 2, it absorbs the vibration energy through the expansion and contraction of the buffer groove 61, thereby achieving a buffering effect. Moreover, the buffer body 60 has a ring-shaped structure, and only... Figure 3 The direction of vibration along the A-axis forms a buffer. This form, achieved through variations in the curvature of the buffer body 60, provides superior buffering performance compared to a straight buffer body 60. Multiple support ribs 62 are provided on the inner surface 60b of the buffer body 60, evenly distributed along its circumference, providing uniform support and giving the buffer body 60 a certain degree of rigidity. The support ribs 62 provide strong, stable, and uniform support while simultaneously transmitting vibrations from the buffer frame 2.

[0013] The vibration suppression speaker provided by this invention transmits the vibration of the speaker frame to the vibration buffer, which then buffers and reduces the transmitted vibration before transmitting it to the mounting frame, greatly reducing the vibration of the mounting frame and achieving a significant vibration suppression effect. The vibration buffer directly connects the speaker frame and the mounting frame, resulting in a very simple structure, reducing assembly work, lowering production costs, and improving production efficiency.
