Abstract
The utility model relates to a loudspeaker for an alarming apparatus of a megaphone, belonging to the technical field of loudspeakers; the loudspeaker is composed of a T iron (1), a magnet (2), a voice coil (3), a plywood (4), a plate rail (5), an elastic wave (6), a light cap (7), a conical diaphragm (8) and a cord bracket (9); the loudspeaker is characterized in that: the diameter of a core hole (10) of the magnet (2) is 15-17mm, the diameter of the elastic wave (6) is 35-40mm, and the thickness of the cord bracket (9) is 0.4-0.9mm. As the diameter of the core hole of the magnet is 15-17mm, the outer diameter of the magnet is small correspondingly, and the volume and input power of the loudspeaker is low; as the diameter of the elastic wave is 35-40mm and the thickness of the conical diaphragm is 0.4-0.9mm, the high pitch effect of the loudspeaker is similar to the loudspeaker with more than 3 inches.
Description
Technical field
The utility model belongs to the loudspeaker technical field, is specifically related to a kind of loudspeaker that are used on the megaphone siren.
Background technology
Be used for the loudspeaker on megaphone and the siren now, volume is big, generally needs with loudspeaker big more than 3 inches, because the specification of loudspeaker is big, so required input power is also big.
Summary of the invention
The purpose of this utility model is that a kind of loudspeaker that are used on the megaphone siren will be provided, and not only volume is little for it, and high pitch is effective, and power consumption is little.
Above-mentioned goal of the invention is achieved through the following technical solutions, a kind of loudspeaker that are used on the megaphone siren, it is made up of T iron, magnet, voice coil loudspeaker voice coil, clamping plate, plate rail, bullet ripple, bright cap, cone, clamp, its main points are that the SMIS bore dia of magnet is 15～17 millimeters, the diameter that plays ripple is 35～40 millimeters, and the thickness of cone is 0.4～0.9 millimeter.
Above-mentioned a kind of loudspeaker that are used on the megaphone siren, one of its structure are that the SMIS bore dia of magnet is 16 millimeters, and the diameter that plays ripple is 38 millimeters, and the thickness of cone is 0.5 millimeter.
The utility model is because the SMIS bore dia of magnet is 15～17 millimeters, so the external diameter of its magnet is also corresponding little, so the volume of loudspeaker and input power are also little; But because play the diameter of ripple is 35～40 millimeters, and the thickness of cone is 0.4～0.9 millimeter, so its high pitch effect is but similar with loudspeaker big more than 3 inches.
