Description

Technical Field

[0001] The present invention relates to the technical field of audio technology, and in particular to a flat-panel audio system with high-frequency compensation. Background Art

[0002] Since its advent, audio has been widely used in various places. Whether it is playing music or videos, audio seems to be everywhere. Audio is an important component of the broadcasting system, and is responsible for the key task of converting electrical signals into sound signals for direct human hearing. Since the human ear's subjective perception of sound is the most important criterion for evaluating the sound quality of an audio system, the performance of the audio plays a key role in the playback quality of an audio system.

[0003] Since their introduction in the 1990s, flat-panel speakers have been favored by some construction companies and used in large venues for their lightweight design and acoustic properties, allowing them to travel farther for the same sound pressure level. However, due to their inherent sound quality, flat-panel speakers have poor high-frequency characteristics, making them unsuitable for venues requiring direct sound and limiting their widespread use. Furthermore, traditional flat-panel speakers offer long transmission distances and minimal sound attenuation within effective distance, but generally suffer from poor high-frequency response. Summary of the Invention

[0004] In order to overcome the deficiencies of the prior art, the present invention aims to provide a flat panel speaker with high frequency compensation, which can solve the problem of poor high frequency response of traditional flat panel speakers.

[0005] In order to achieve the above object, the technical solution adopted by the present invention is as follows:

[0006] A flat-panel speaker with high-frequency compensation includes a frame consisting of several frame bars, several vibrating plates for generating sound through vibration, a driver for driving the vibrating plates to vibrate, and a high-frequency compensation device for compensating for high frequencies. The frame is provided with several sound-generating surfaces, the vibrating plates are laid on the sound-generating surfaces, and the driver and high-frequency compensation device are both laid on one end surface of the vibrating plates close to the frame.

[0007] Preferably, it further comprises a fixed driving bracket for limiting the driver and the high-frequency compensation device to be in the same plane, and the driver and the high-frequency compensation device are both connected to the fixed driving bracket.

[0008] Preferably, the vibration plate is a honeycomb plate.

[0009] Preferably, the number of the sound-emitting surfaces is 4, which are respectively recorded as the first sound-emitting surface, the second sound-emitting surface, the third sound-emitting surface and the fourth sound-emitting surface. The first sound-emitting surface and the second sound-emitting surface are arranged side by side, and the vibration plate is laid on the first sound-emitting surface and the second sound-emitting surface. The first sound-emitting surface is connected to the third sound-emitting surface, and the second sound-emitting surface is connected to the fourth sound-emitting surface.

[0010] Preferably, the high-frequency compensation device is a tweeter.

[0011] Preferably, an end surface of the vibration plate away from the frame is covered with a first mesh cover, and an edge of the first mesh cover is connected to the frame.

[0012] Preferably, a second mesh cover is further included, wherein an edge of the second mesh cover is connected to a side of the frame away from the vibration plate.

[0013] Preferably, it also includes a plurality of fixing brackets for fixing the placement of the frame, and the fixing brackets are fixedly connected to the frame.

[0014] Compared with the existing technology, the beneficial effects of the present invention are: high-frequency compensation is performed on the flat-panel speaker through the high-frequency compensation device to solve the problem of its poor high-frequency response, making the frequency response wider and the sound clearer. At the same time, the driver and the high-frequency compensation device are both laid on the end surface of the vibration plate close to the vibration cavity to reduce the overall thickness of the speaker, and the vibration plate is used to generate sound, thereby increasing the vibration area so that sound can be generated on both sides.

For example, they may refer to fixed, detachable, or integral connections; mechanical or electrical connections; direct or indirect connections through an intermediate medium; and internal communication between two components. Those skilled in the art will understand the specific meanings of the above terms in the present invention based on the specific circumstances.

[0021] The present invention will be further described below with reference to the accompanying drawings and specific embodiments:

[0022] In the present invention, the frame 1 can be surrounded by multiple aluminum / aluminum alloy frame bars to reduce the overall weight of the flat-panel speaker. The driver 3 receives external audio signals, processes the signals, and then drives the vibration plate 2 to vibrate and generate sound. During this process, the driver 3 converts the electrical signal into a force acting on the vibration plate 2.

[0023] like Figure 1-2 As shown, in this embodiment, a flat-panel speaker with high-frequency compensation includes a frame 1 formed by a plurality of frame bars, a plurality of vibrating plates 2 for generating sound through vibration, a driver 3 for driving the vibrating plates 2 to vibrate, and a high-frequency compensation device 4 for compensating for high frequencies. The frame 1 is provided with a plurality of sound-emitting surfaces, the vibrating plates 2 being laid on the sound-emitting surfaces, and the driver 3 and high-frequency compensation device 4 being laid on the end surface of the vibrating plates 2 near the frame 1. Preferably, the high-frequency compensation device 4 is a tweeter, which serves as a high-frequency supplement to the flat-panel speaker, providing a wider frequency response and clearer sound. Furthermore, the vibrating plate 2 is a honeycomb plate, replacing a traditional conical speaker, increasing the vibration area, improving sound pressure, and preventing sound distortion. The honeycomb plate is provided with through holes on both sides of the end surface, and there are four sound-emitting surfaces, designated as a first sound-emitting surface, a second sound-emitting surface, a third sound-emitting surface, and a fourth sound-emitting surface. The first sound-emitting surface and the second sound-emitting surface are arranged side by side. Preferably, the first sound-emitting surface and the second sound-emitting surface are each laid with a honeycomb plate. The first sound-emitting surface is connected to the third sound-emitting surface, the second sound-emitting surface is connected to the fourth sound-emitting surface, and a driver 3 and a high-frequency compensation device 4 are arranged between the first sound-emitting surface and the third sound-emitting surface, and a driver 3 and a high-frequency compensation device 4 are also arranged between the second sound-emitting surface and the fourth sound-emitting surface. When the driver 3 drives its corresponding honeycomb panel to vibrate, the generated sound radiates outward from the end surfaces on both sides of the honeycomb panel, that is, the first sound-emitting surface, the second sound-emitting surface, the third sound-emitting surface and the fourth sound-emitting surface all transmit the sound emitted by the honeycomb panel outward, and at the same time, the high-frequency compensation device 4 (tweeter) performs high-frequency compensation to realize double-sided sound of the flat-panel speaker.

[0024] Preferably, a fixed driver bracket 5 is further included to ensure that the driver 3 and the high-frequency compensation device 4 are located on the same plane. The driver 3 and the high-frequency compensation device 4 are both connected to the fixed driver bracket 5. In this embodiment, the driver 3 and the high-frequency compensation device 4 are both installed on the same plane, replacing the traditional stacking method, thereby reducing the overall thickness of the speaker and achieving an ultra-thin thickness of the flat panel.

[0025] Preferably, the end face of the vibration plate 2 away from the frame 1 is covered with a first mesh cover 6, the edge of the first mesh cover 6 is connected to the frame 1, and the side of the frame 1 away from the vibration plate is covered with a second mesh cover 7, the edge of the second mesh cover 7 is connected to the frame 1, that is, the first mesh cover 6 and the second mesh cover 7 cover the first sound-emitting surface, the second sound-emitting surface, the third sound-emitting surface and the fourth sound-emitting surface to protect the various components inside the flat-panel speaker, while maintaining the connection between each sound-emitting surface and the outside world, so that the sound generated by the vibration of the vibration plate 2 (honeycomb panel) can be effectively transmitted. Furthermore, it also includes a number of fixing brackets 8 for fixing the placement position of the frame 1, and the fixing brackets 8 are detachably connected to the frame 1. Users can connect to external walls, roofs, etc. through the fixing brackets 8 to fix the flat-panel speaker in a specific position.

[0026] Those skilled in the art can make various other corresponding changes and deformations based on the technical solutions and concepts described above, and all of these changes and deformations should fall within the scope of protection of the claims of the present invention.
