There are several differences between active speakers and passive speakers, which involve audio signal processing, power amplification, and applicable scenarios.
Active Speakers:
Built-in Amplifier: Active speakers have a built-in amplifier, allowing them to directly connect to low-level audio signals outputted by audio source devices (such as phones, computers, CD players, etc.) without requiring additional amplifiers.
Adjustable Audio Parameters: Active speakers usually come with built-in audio adjustment functions, such as volume, bass, treble, etc., which users can adjust according to personal preferences or environmental requirements.
Self-powered: Active speakers come with built-in amplifiers, enabling them to directly drive speakers and output amplified audio signals without the need for additional amplifier devices.
Passive Speakers:
Require External Amplifiers: Passive speakers do not have built-in amplifiers and require external amplifiers to amplify audio signals. Therefore, they must be connected to external amplifier devices to produce sound.
Fixed Audio Parameters: Passive speakers typically lack built-in audio adjustment functions, and parameters such as volume, bass, treble, etc., cannot be adjusted by users.
Require Additional Equipment: Since passive speakers do not have built-in amplifiers, they require additional amplifier devices for use, which adds complexity and cost to the system.
Summary of Differences:
Connection Method: Active speakers can directly connect to audio source device outputs, while passive speakers require external amplifiers to drive them.
Functional Features: Active speakers usually have audio adjustment functions, whereas passive speakers do not possess these functions.
Cost and Complexity: Active speakers are relatively simpler as they have built-in amplifiers, while passive speakers require additional amplifier devices, potentially increasing cost and system complexity.
Based on actual needs and budget considerations, choosing the appropriate type of speaker can better meet user requirements.
