Description

Technical Field

[0001] The utility model relates to the technical field of strong-voice loudspeakers, in particular to a strong-voice loudspeaker with strong light searchlight. Background Art

[0002] A loudspeaker is a device used to amplify sound. It usually consists of a speaker, an amplifier, and a power supply. By inputting the sound signal into the amplifier, the amplifier will convert the signal into a large enough current to drive the speaker to produce a high volume of sound. A loudspeaker generally uses a horn-shaped speaker, which can diffuse the sound horizontally, so that the sound can be clearly transmitted over a long distance to achieve the purpose of shouting or conveying information. This type of equipment is usually widely used in outdoor, emergency, warning, broadcasting and other occasions, such as police shouting, emergency evacuation instructions, public broadcasting, etc. The power of a loudspeaker is generally large, and it can produce a large sound pressure level to ensure that the sound can be transmitted and heard in a noisy environment.

[0003] Existing loudspeakers are mainly used in airports, reefs and birds, special occasions to disperse dangerous animals, border protection, reef protection, prison management, riot suppression, etc. When used in reef protection, they will be eroded by rain for a long time. At the same time, when it rains, too much rain enters the loudspeaker, which may cause damage to the internal components, or the external part is eroded by acid rain for a long time, resulting in damage, loss or loss of sound effect. In addition, many loudspeakers do not have lighting function, and the direction of sound transmission is not clear and accurate enough. Utility Model Content
