What is The Main Difference Between Directional Speaker and Conventional Speaker?

Image
  Conventional speakers are mostly sound-generating devices based on the moving-coil principle, and the directivity of all conventional speakers is fundamentally limited by the size of the source compared to the wavelength it produces. Large-size speakers will be more directional than small speakers, or speakers specified at higher frequencies (smaller wavelengths) will also be more directional. However, acoustic devices based on conventional acoustic theory also have a common feature, that is, the sound emitted is uncontrollable and omnidirectionally propagated to the surrounding space.   The sound wave propagation mode of conventional speakers is "domineering", with 360° expansion in all directions, spreading divergently around, and the volume decreases with the increase of distance, the transmission range is determined by the volume. If the volume is large and the transmission range is wide, it is very easy to cause noise disturbance; if the volume is small and the transmi...

What Are the Uses of Directional Sound Technology?

Image
  1. Introduction of directional sound technology   Sound orientation is a sound technique for a specific field of orientation. Sound directional technology can be used in many different types of applications, from home entertainment to consumer product development. Some sound-directing techniques are created using speaker arrays – these types of techniques can be used for the acoustics of performance venues or other public facilities.   The ultrasonic directional speaker  emits two columns of modulated ultrasonic waves with a certain frequency. The two ultrasonic waves have a nonlinear effect in the air to form a frequency difference signal of the two columns of ultrasonic waves. Listen to the sound and achieve directional transmission like a laser, which can only be heard within a specific area.   2. The use of directed sound technology   Generally, sound directional technology is used in museums and exhibitions. Besides, can sound directional technology ...

Wall-Mounted Directional Speaker

Image
  A wall-mounted directional speaker, just as its name implies, refers to a directional sound speaker that hangs on the wall.   Wall-mounted outdoor directional speakers  are widely used in various scenarios indoor and outdoor. Simple and safe wall mount installation, ideal for industrial and commercial applications such as museums, exhibition halls, hotels, schools, offices and factories to meet directional audio transmitting.   In the museum, the wall-mounted directional speakers are aimed at the desired listening area and provide directive sound and leaving almost no noise nearby. Various museums can choose this directional sound speaker to provide comfortable interpretation of exhibitions while maintaining a quiet sound environment.   For example, in outdoor advertising, wall-mounted ultrasonic directional speaker  is mostly applied in digital signage and large-screen advertising, which has an incomparable impact on promoting sales.   We can offer ...

Use Directional Speakers in Museums and Galleries

Image
  1. What is a directional speaker ?   A directional speaker is a directional audio ultrasonic speaker  that plays a straight beam of sound so it can only be heard when you are in a specific place. They are used in many different places where sound needs to be localized to a specific place. For example, public address, retail display, interactive kiosk or art exhibit.   They are an innovative way to grab people's attention and give them useful information without disturbing others in the same space. They are far more hygienic than a set of headphones that people share, and fit neatly into your space setup without changing your design aesthetic. Installation of most directive speakers is fairly straightforward. While the technology inside is complex, the product is simple: a relatively flat shape, the size of a dinner plate, with a sound on one side. This means that any flat surface can hold them (such as walls, structures or ceilings), or you can attach them to the s...

The Working and Use of Directional Loudspeaker Technology

Image
  1. How does directional speaker technology work?   Directional speaker technology  produces directional audio in a precise, fixed shape and direction with a precision similar to that of light. Audio is delivered clearly to the target area and critically without adding to ambient noise in nearby environments.   2. The use of directional loudspeaker technology   Sound directional speakers are ideal for situations where sound reproduction needs to be localized to a certain area while remaining quiet elsewhere. This directional loudspeaker technology is particularly suitable for applications around tourist attractions and public places where sound needs to be directed or controlled. Prime examples include promotions in retail showrooms or exhibitions, displays in art galleries or museums, and even targeted public address and warning systems. Museums and galleries are an attraction that should be an informative, relaxing experience. Visitors to such venues expect a...

How Directional Loudspeakers Work | How is It Different from Ordinary Speakers?

Image
  H ow D irectional S peakers W ork ?   Directional audio technology has gradually entered all aspects of life. For example, at intersections waiting for traffic lights, there are directional audio safety prompts, which can be directed to pedestrians waiting for traffic lights. Safety prompts do not produce noise effects, creating a good life for citizens. surroundings. How is the working principle of ultrasonic directional speakers  different from ordinary speakers?   1. The special features of directional audio technology   The audible sound wave emitted by most of our common speakers is a common mechanical wave. Its propagation in the air is spherical, divergent, easy to attenuate, and affects the propagation effect. The audible sound wave is radiated 360 degrees. At different frequencies and angles, the energy of the sound wave will be different, and it is easy to attenuate when it propagates in the air; the 360-degree radiation characteristics determine tha...

Directional Speaker Technology for Offices and Command and Control Centers

Image
  1. The application of directional speaker technology in the office   Directional speaker technology is not limited to use in industries such as museums and retail. Also help improve the work environment by having them in the office. There are two main uses for office directional speakers: to create a pleasant and immersive work environment, and to use a combination of facial recognition and directional audio for entrance greetings.   The use of ultra directional speaker  technology in the office can create an immersive and relaxing experience in the reception room, hallway, and rest area. Most large offices typically have rooms, such as waiting areas or lounges, where TVs are on 24/7, directional speakers for office  can also provide localized sound, and computer vision, which companies can use to deliver personalized greeting messages to employees.   2. Directional speaker technology applied to command and control center   Directional speaker techno...

Characteristics of Directional Sound Technology

Image
  Nowadays, everyone pays attention to privacy. Whether it is at home or public space, work or entertainment, headphones have become the first choice for obtaining audio sources. However, wearing headphones for a long time will cause more or less hearing damage to a certain extent; Hearing loss is common among the elderly. In daily life, the elderly often make up for the lack of hearing by increasing the volume of the sound. However, the excessively high volume will not only cause a certain degree of distress to the family members around them, but also invisibly damage the hearing of themselves and their family members to varying degrees.   1. The emergence of directional sound technology   In today's 21st century technology era, directional sound technology realizes the directional transmission of audible sound, creates an independent audio space around the human ear, and can clearly obtain sound information without wearing headphones. Non-interfering sound area, efficie...
