2. Recommended speaker types suitable for LED screens
1). Built-in speakers
Built-in speakers, as the name suggests, are speakers installed directly inside the LED screen. This type of speaker is very compact and does not take up additional space.
It is very suitable for occasions where space is limited, or there are high requirements for the overall design. Built-in speakers are usually tightly integrated with the frame or back panel of the display screen.
From the appearance, they are like part of the display screen, which is very neat and beautiful.
- Sound quality and use:
Although the sound quality of built-in speakers may not be comparable to that of professional external speakers, they are sufficient for general information broadcasting, background music playback, and other needs.
In places such as shopping malls, supermarkets, conference rooms, or small exhibition halls, built-in speakers can provide clear and audible sound to meet basic auditory needs.
- 适用场景：
Indoor LED advertising screens in retail places such as shopping malls and supermarkets are used to play promotional information or background music.
Meeting rooms, small 展览 halls and other occasions where the environment needs to be kept clean are used for conference speeches or presentations.
2). External speakers
External speakers are speaker systems independent of LED display screens. They can choose speakers of different power and sound quality as needed to meet larger sound coverage and higher sound quality requirements.
External speakers usually include speaker cabinets, power amplifiers, audio processors, and other equipment, which can be flexibly arranged around or far away from the display screen to achieve the best sound effect.
- Sound quality and use:
The sound quality of external speakers is usually better than that of built-in speakers, and can present clearer, fuller and more layered sound.
They are suitable for occasions that require high-quality sound effects, such as concerts, concerts, cinemas, theaters, etc. On these occasions, external speakers can create a more shocking and immersive sound experience, allowing the audience to feel a more realistic music or picture atmosphere.
- 适用场景：
Outdoor large LED screens, such as squares and stadiums, are used to play live sounds of large-scale events or competitions.
Concerts, concerts, and other literary performances that require high-quality sound effects.
Cinemas, theaters, and other places need to create an immersive sound experience.
3). Waterproof sound column
A waterproof sound column is a type of speaker designed for outdoor or special environments. They have characteristics such as being waterproof, dustproof, and weather-resistant, and they can work stably in harsh environments.
Waterproof sound columns are usually designed to be slender to reduce floor space and provide a more uniform sound distribution. This type of speaker is not only suitable for outdoor LED screens but is also widely used in campuses, factories, swimming pools, and other occasions that require public broadcasting systems.
- Sound quality and use:
Although the sound quality of waterproof sound columns may not be as good as that of professional speakers, they are sufficient to meet the needs of outdoor advertising, background music, etc.
In outdoor environments, waterproof sound columns can clearly transmit sound to ensure that the audience can hear the content being played clearly.
At the same time, their waterproof and dustproof properties also ensure the normal operation of the speakers in bad weather.
- 适用场景：
Outdoor LED display screens, such as parks, scenic spots, streets, etc., are used to play advertisements, notices or background music.
Situations such as campuses and factories that require public broadcasting systems are used to play notices, broadcasts, or background music.
Entertainment venues such as swimming pools and water parks that require waterproof speakers are used to play music or provide safety tips.
3. Matters worth noting
In the process of connecting the LED display screen and the speaker, there are indeed some matters worth noting to ensure the stable operation of the system and extend the service life of the equipment.
The following is a detailed explanation of the three matters you mentioned:
1). Avoid power mismatch
- The impact of excessive power:
If the power of the speaker is much greater than the audio output capacity of the LED display screen, it may cause the signal received by the speaker to be too weak, unable to fully exert the performance of the speaker, and may even damage the input circuit of the speaker.
In extreme cases, if a high-power speaker is directly connected without proper power-matching equipment (such as an amplifier), the audio output interface of the LED display may be damaged due to excessive current.
- Impact of too little power:
If the power of the speaker is too small, the audio content on the LED display may not be played clearly, especially in a large space or noisy environment.
Long-term use of speakers with unmatched power may also cause the speaker to overload, affecting its performance and life.
- 解决方案：
When selecting a speaker, the appropriate speaker power should be selected according to the audio output capacity and actual needs of the LED display.
If a higher volume or sound quality requirement is required, consider using an amplifier to match the power of the speaker and the display.
2). Consider electromagnetic compatibility
- The impact of electromagnetic interference:
LED displays and speakers will generate certain electromagnetic radiation when working.
If the electromagnetic compatibility between these devices is not good, mutual interference may occur, resulting in audio distortion, screen flickering, and other problems.
In some complex electromagnetic environments (such as large electrical equipment, radio transmission towers, etc. nearby), it may also be affected by external electromagnetic interference, affecting the normal operation of the system.
- 解决方案：
Choose LED display screens and speaker products with good electromagnetic compatibility.
During installation and wiring, be careful not to parallel or cross the audio cables, power cables, etc., of the speakers with the signal cables, power cables, etc., of the display screen to reduce mutual interference.
When necessary, electromagnetic shielding materials or equipment can be used to isolate the interference source.
3). Regular maintenance
- The importance of maintenance:
Regular inspection of speakers and connection lines can help discover and solve problems, such as loose joints, aging lines, etc., in a timely manner, thereby avoiding the occurrence of failures.
Clean the dust and dirt on the speakers and display screens to maintain the heat dissipation performance of the equipment and extend its service life.
- The specific content of maintenance:
Check whether the connection line of the speaker is firm and reliable, without looseness or damage.
Clean the dust screen, heat sink, and other components of the speaker to maintain good ventilation.
Check whether the power cable, signal cable, etc. of the LED display screen are connected correctly and stably.
Clean the surface and inside of the LED display screen (if possible) to remove dust and dirt.
Perform functional tests on the speakers and display screens regularly to ensure that they work properly.
