Abstract
The utility model relates to a plastic electronic loudspeaker. General automobile loudspeakers uses iron shells, iron pressing covers and membranes with steel material to rivet together to form a sound generating device, so the loudspeaker with the structure has high cost, heavy weight, complex manufacturing technique, high energy consumption, ordinary sound effect and sound level which is not high enough. The utility model comprises a coil (4) which is connected with an iron bowl (6); the iron bowl (6) is connected with a plastic shell (5); the bowl opening of the iron bowl (6) is connected with a steel vibration piece (3). The utility model relates to an automobile electronic loudspeaker.
Description
Technical field:
The utility model relates to a kind of automobile electronic loudspeaker.
Background technology:
The general-utility car loudspeaker use the irony housing, and the diaphragm of irony gland and steel matter rivets together, and form sound-producing device, the loudspeaker cost height of this structure, and quality is heavy, complex manufacturing technology, and energy consumption height, sound effect is general, and sound level is not high enough.
Summary of the invention:
The purpose of this utility model provides a kind of light weight, and manufacture craft is simple, and energy consumption is low, and sound effect is good, the plastic electronic loudspeaker that sound level is high.
Above-mentioned purpose realizes by following technical scheme:
Plastic electronic loudspeaker, its composition comprises: coil, described coil connects with the iron bowl, and described iron bowl connects with plastic casing, and the rim of a bowl of described iron bowl and the steel sheet that shakes connects.
Described plastic electronic loudspeaker, the described steel sheet that shakes connects with plastic film by counterweight, described plastic film and plastics gland, plastic casing riveted joint.
The beneficial effects of the utility model:
1. iron bowl in the utility model, coil, counterweight and the steel sheet that shakes constitutes vibroseis together, and this vibroseis is littler than the space of original common loudspeaker, and magnetic circuit is short, and magnetic density is big, can obtain bigger electromagnetic force with less current, makes the steel sheet vibrations of shaking more violent.
2. the steel sheet volume that shakes is little, in light weight in the utility model, causes vibrations than common loudspeaker are easier, so energy consumption is low, the sound effect of generation is good.
3. the plastic film in the utility model is than the steel diaphragm light weight in the common loudspeaker, stressed easy vibrations, utilize the shake vibrations of sheet of steel to drive the plastic film vibrations, under the state of same electromagnetic force, its vibration amplitude will directly be utilized the amplitude of steel diaphragm vibrations much larger than common loudspeaker, so sound effect is better than the sound effect of common loudspeaker, sound level is also than common loudspeaker height.
4. the utility model horn structure frequency response curve can be more smooth, and is not sharp-pointed, and this just is suitable for doing broadband music loudspeaker.
Description of drawings:
Accompanying drawing 1 is a structural representation of the present utility model.
Embodiment:
Embodiment 1:
Plastic electronic loudspeaker, its composition comprises: coil 4, described coil 4 connects with iron bowl 6, and described iron bowl 6 connects with plastic casing 5, and the rim of a bowl of described iron bowl 6 and the steel sheet 3 that shakes connects.
Shake sheet 3 of described plastic electronic loudspeaker, described steel connects with plastic film 1 by counterweight 7, and described plastic film 1 and plastics gland 2, plastic casing 5 are riveted.
Claims (2)
1. plastic electronic loudspeaker, its composition comprises: coil is characterized in that: described coil connects with the iron bowl, and described iron bowl connects with plastic casing, and the rim of a bowl of described iron bowl and the steel sheet that shakes connects.
2. plastic electronic loudspeaker according to claim 1 is characterized in that: the described steel sheet that shakes connects with plastic film by counterweight, described plastic film and plastics gland, plastic casing riveted joint.
