Description

Deep waterproof loudspeaker

Technical Field

The utility model relates to a loudspeaker technical field especially relates to waterproof type loudspeaker of degree of depth.

Background

The loudspeaker is a modern electroacoustic component, the function is to convert the electrical signal into sound, also called loudspeaker, the loudspeaker is a kind of conversion equipment that the electrical energy is converted into sound, when different electronic energy is transmitted to the coil, the coil produces an energy and magnetic field interaction of the magnet, this interaction causes the paper disc to vibrate, because the electronic energy changes at any time, the coil of the loudspeaker will move forward or backward, so the paper disc of the loudspeaker will move, this movement makes the density degree of the air change and produce the sound, set up the movable iron chopping piece (armature) in the middle of a U-shaped magnet, when the current flows through the coil, the armature will be magnetized and the magnet produces the phenomenon of repulsion, and drive the vibrating diaphragm to move at the same time, this kind of design cost is cheap but not good in effect, so use on telephone receiver and small-sized earphone, the inductive loudspeaker is similar to the electromagnetic principle, however, the armature is doubled and the two voice coils on the magnet are not symmetrical, and the two armatures move to push each other for different magnetic fluxes when the signal current passes through.

The loudspeaker is common public address equipment in our daily life, and its range of application is very extensive, for example, all install loudspeaker in cell-phone, earphone, stereo set, intercom commonly used in our, still be provided with loudspeaker in the intercom, but there is certain defect in the current intercom loudspeaker structural design at present, under some special circumstances, the diver can carry the intercom to dive, in order to listen to from the commander on shore personnel, but the waterproof performance of current intercom loudspeaker is relatively poor, in case dive in the deep water district, loudspeaker are very easy to intake, thus lead to the damage of intercom, for this reason, we have proposed new deep waterproof type loudspeaker.
