The difference between Bluetooth speakers and broadcast speakers:

Connection Method:

Bluetooth Speakers: Bluetooth speakers wirelessly connect to other devices (such as smartphones, tablets, computers, etc.) using Bluetooth technology to transmit audio signals. Users can wirelessly stream audio content from their phones or other Bluetooth devices directly to the Bluetooth speaker.

Broadcast Speakers: Broadcast speakers typically use wired or wireless broadcast signals for audio transmission. They are usually connected to a broadcasting system, such as FM radio, AM radio, or through dedicated wireless transmission systems. Users can receive the audio signals sent by broadcast speakers through FM or AM radio receivers.

Usage Range:

Bluetooth Speakers: Bluetooth speakers are primarily used in personal and home environments, such as at home, office, or outdoors. Due to their portability and wireless connectivity, Bluetooth speakers are suitable for playing music, watching videos, and other audio playback on mobile devices.

Broadcast Speakers: Broadcast speakers are mainly used in public places such as shops, office buildings, stations, stadiums, etc. They are used for broadcasting background music, announcements, news, advertisements, etc., to cater to a large audience or listeners.

Power and Sound Quality:

Bluetooth Speakers: Bluetooth speakers are usually designed with portability and personal use in mind, and their power and sound quality may be relatively lower, suitable for personal enjoyment within a small range.

Broadcast Speakers: Broadcast speakers are designed to provide higher power and better sound quality to cater to the needs of sound propagation in a larger area.

Control Method:

Bluetooth Speakers: Bluetooth speakers are typically manually controlled by users, using buttons, remote controls, or the connected device's application to adjust volume, switch songs, etc.

Broadcast Speakers: Broadcast speakers are usually controlled by the broadcasting system, and the playback content is pre-set by the broadcasting system. Users generally cannot have personalized audio control.

In summary, Bluetooth speakers are suitable for personal use, with portability and personalized audio control, while broadcast speakers are suitable for public places, widely distributing audio content, with higher power and better sound quality, but with some limitations on user's personalized control.
