    摘要： A portable acoustic warning device which projects a specific acoustic waveform towards a target, creating a narrow beam of sound that is highly selective, minimizing exposure to users and bystanders, while enabling a controlled dosage of sound to be applied to the target. The design of the device is tailored to this waveform thus achieving a very high degree of directivity. It is not intended for communicating verbal messages. This waveform achieves maximum intensity at the target while using a relatively low sound pressure level; meaning that the exposure levels can be controlled to ensure they are within existing health and safety legislation. A laser range finder limits the sound level at the target to a pre-determined level. An integrated camera is used to aid aiming. Video footage is recorded with use; along with the sound level at the target, exposure duration, time, date and GPS coordinates.

    摘要： A speaker device (100) includes a speaker device terminal (50) including a pair of terminal metals (52,53) and a terminal metal mounting part (51) on which the pair of terminal metals (52, 53) are mounted, and a frame (4) including a terminal mounting part (4ba) on which the speaker device terminal (50) is mounted. The terminal mounting part (4ba) is provided on a rear side of the frame (4) positioned on a side opposite to a sound output side. The speaker device terminal (50) is mounted on the terminal mounting part (4ba) in such a state that the pair of terminal metals (52,53) are mounted on the terminal metal mounting part (51) positioned on the side opposite to the sound output side. The terminal metal mounting part (51) has a projecting part (51a) projecting on the side opposite to the sound output side. A height of the projecting part (51a) in the projecting direction is higher than heights of the pair of terminal metals (52,53) in the projecting direction.
