Description

Technical Field

[0002] "La horn" has different meanings in different contexts. In Mandarin, "La horn" usually refers to a loudspeaker or amplifier, which is used to amplify sound so that more people can hear it. In the automotive field, "La horn" refers to the horn device on the vehicle. In addition, in the field of music, "La horn" can refer to various wind instruments, such as trumpet, trombone, etc.
