Description

Technical Field

[0001] The utility model relates to the technical field of loudspeakers, in particular to a dual waveguide array loudspeaker. Background Art

[0002] Speakers are commonly known as "horns". They are a very common electroacoustic transducer device that can be found in electronic and electrical equipment that produces sound.

[0003] The shortcomings of the current mainstream array column speakers can be analyzed from the following aspects:

[0004] 1. The sound wave directivity is poorly controlled and the directivity performance is poor, making it difficult to accurately focus the sound field, resulting in insufficient volume or uneven sound quality in some areas;

[0005] 2. The frequency response is unbalanced, and the attenuation of high-frequency and low-frequency sound waves is inconsistent;

[0006] 3. The sound coverage is limited. Array column speakers without waveguides may find it difficult to achieve wide sound coverage, especially in large venues.

[0007] 4. Poor anti-reflection and feedback performance, which easily generates unnecessary reflected sound waves, resulting in obvious echo effect and impaired sound quality;

[0008] 5. The sound attenuation is significant. The sound is easily attenuated during the transmission process, especially at a long distance from the listener.

[0009] 6. The design lacks flexibility and the ability to adjust the sound field, making it difficult to adjust according to venue requirements.

[0010] These shortcomings may affect the overall sound quality performance of the array column speaker, especially in applications that require a large sound field coverage, uniform sound pressure level and high sound quality requirements, such as auditoriums, stadiums and lecture halls.

[0015] As an improvement, an air guide hole is provided at the bottom of the front end of the wooden speaker box.

[0016] As an improvement, hanging screw seats are provided on the upper and lower sides of the wooden speaker box.

[0017] As an improvement, the rear end of the wooden speaker box is provided with wall-mounted bracket screws and connecting piece mounting screws.

[0019] As an improvement, the number of the waveguide plates is two and they are symmetrically arranged.

[0020] (3) Beneficial effects

[0021] The advantages of this utility model compared with the prior art are:

[0022] 1. Precise sound wave directivity control: Digital waveguide technology allows for precise control of the sound output time and phase of each speaker unit, achieving fine-tuning of the sound wave directivity. This allows the array speaker to focus the sound on a specific area, preventing it from spreading in unwanted directions, significantly improving the efficiency of sound coverage.

[0023] 2. More uniform frequency response. The function of the physical waveguide is to guide and diffuse sound waves, thereby optimizing the output of the speaker in different frequency ranges and reducing distortion or imbalance between high and low frequencies. Speakers with a waveguide design can maintain a smooth and stable frequency response in all frequency bands, improving the clarity and fullness of the sound quality.

[0024] 3. Wider sound coverage: The digital waveguide and physical waveguide design can effectively enhance the sound diffusion capability, allowing the speaker to evenly distribute sound over a larger area. This is very important for covering a wide audience, especially in places such as lecture halls, theaters, and churches where sound needs to be transmitted over long distances.

[0025] 4. Reduce sound wave reflections and echoes. Physical waveguides can effectively reduce the reflection of speakers on surfaces such as walls and ceilings by guiding the sound wave path, thereby reducing sound quality distortion caused by echoes and reflections. Digital waveguide technology can also avoid feedback and acoustic interference through computational processing, ensuring clear and interference-free sound.

[0026] 5. Reduce sound attenuation. Through precise waveguide design, the speaker can effectively control the energy of the sound and reduce the phenomenon of rapid sound attenuation with increasing distance. This means that even at a distance, the audience can enjoy high-quality sound effects without relying on multiple speakers to supplement the sound pressure.

[0027] 6. Flexible sound field adjustment: Digital waveguide technology can dynamically adjust the sound projection method according to different acoustic environments, providing more flexible sound field control. Whether you need wide sound field coverage or need to concentrate the sound in a specific area, the system can be adjusted through software to achieve customized sound performance;

[0028] 7. Reduce phase interference. In a sound column array, if the sound waves of adjacent units are not controlled, phase interference is likely to occur, resulting in unstable or distorted sound quality. Digital waveguide technology can precisely control the sound wave phase of each speaker unit, thereby eliminating phase interference and improving the purity and accuracy of the sound.

[0029] 8. Enhanced low-frequency performance: Physical waveguides can also help improve the low-frequency performance of speakers. By guiding low-frequency sound waves and reducing attenuation and diffusion, the waveguide design enables the array sound column to produce stronger low-frequency output, making the sound effect fuller and less distorted.

[0030] 9. More integrated system design. Speakers with waveguide and digital waveguide technology are usually highly integrated systems that can achieve automatic optimization through digital signal processors (DSP). This means that in complex acoustic environments, the system can adaptively adjust output parameters, reducing the need for human intervention and improving ease of use.

[0031] 10. Clearer dialogue or music reproduction: Digital waveguide technology precisely controls the sound field, ensuring not only uniformity but also enhanced clarity of speech or music. This allows listeners in large venues to hear every detail, regardless of their seating position. This is especially important in conferences, lectures, or concerts.
