The utility model discloses well the device satisfies security requirements, can provide certain choice for navigating mate again, ensures safe driving, as for relating to ears loudness, roughness in the loudspeaker manufacturing and sharply spending three quality factor, then needs engineer to take all factors into consideration on product quality, rationally solves and improves the product quality.
Description
Technical field
The utility model relates to loudspeaker technical field, particularly relates to a kind of variable announcement loudspeaker.
Background technology
Current horn trumpet mainly contains two kinds: dynamic loud-speaker and air pressure horn.Dynamic loud-speaker has: basin type loudspeaker and snail loudspeaker and siren loudspeaker, be mainly used on car, utilizes electricity as important power.Air pressure horn: be mainly used on large-scale goods carrying vehicle and motor omnibus, utilizes high pressure gas as power, and sound large propagation is far away.Simultaneously the sound of horn trumpet also has three parameter indexs: ears loudness, roughness and sharpness, all affects auditory perception and the tolerances at heart of people.In conjunction with horn trumpet national standard " self-propelled vehicle safe and technical specification " (GB7258-2004) and " People's Republic of China's urban area noise strength standard " regulation, the volume conversion of this project horn trumpet is roughly divided into three segments: less than 40 yards volumes (recommended value is 60db) less than normal, 40 to 80 yards of volumes moderate (recommended value is 90db), more than 80 yards volumes (recommended value is 115db) bigger than normal.When less than 40 yards, vehicle mainly travels in urban district, is all generally that distance pedestrian and other vehicle are comparatively near, a little bit smaller proper also very hommization of sound of horn volume; When car speed more than 40 yards again less than 80 yards time, vehicle mainly travels on major urban arterial highway, overpass or countryside highway, the speed of a motor vehicle is now than very fast, if need safety instruction, general is all that distance pedestrian and other vehicle are comparatively far away, and it is a bit just suitable that sound of horn volume needs strengthen; When car speed is more than 80 yards, vehicle travels on a highway mostly, and quickly, at this moment horn for vehicle reminds sound also to need very large volume to speed, such guarantee pedestrian and can hear that loudspeaker are pointed out apart from far vehicle.Consider the complexity of vehicle drive environment, this project specially adds a function, if namely chaufeur thinks that situation is complicated at that time, need suitable VOLUME UP, prompting pedestrian or other vehicles, then can take the mode of continuous blast the horn to solve, this item setup is long temporally more than 2 seconds, third gear loudspeaker all can improve one grade of volume again on the basis of original volume, to reach the effect of prompting, greatly increase the practicality of these loudspeaker and handling.
