Problems solved by technology

[0009] refer to Image 6 As shown, due to the narrow width and edge effect, the magnetic flux collected by the plates P1 and P2 with small thickness is not uniform, so the coil C placed between them cannot vibrate up and down and receive linear magnetic force
In addition, since the density of the magnetic flux MF in the space where the coil C vibrates is concentrated on the side of the magnet M, it is stronger, and the upper side, which is the opposite side of the magnet M, is weaker.
Therefore, it is difficult to maintain the balance of the vertical vibration force of the coil, thereby reducing the possibility of achieving excellent sound quality

Abstract

The present invention relates to a speaker. A speaker according to the present invention comprises: a pair of permanent magnets arranged on open opposite sides of a solenoid coil having a rectangularbox shape; and a first setting case and a second setting case for setting positions of the solenoid coil and the permanent magnets or minimizing leakage flux thereof. The present invention allows thepositions of the solenoid coil and the permanent magnets to be set accurately in a production phase and thus has an advantage of improved productivity.

Description

technical field [0001] The invention relates to a loudspeaker. Background technique [0002] Speakers using solenoid coils are classified into dynamic speakers and armature speakers. [0003] The dynamic speaker is a moving coil type speaker, and is composed of a permanent magnet, a coil, and a vibrating plate that vibrates according to the movement of the coil, and the vibrating plate vibrates as the coil moves. That is, when a current flows through the coil, the coil vibrates under the influence of the magnetic field formed by the permanent magnet, and the vibrating plate vibrates along with the vibration of the coil to generate audio. [0004] The armature speaker includes a permanent magnet, a coil, an armature magnetized by a current flowing through the coil, a drive rod connected to the armature, and a vibration plate that oscillates together according to the vibration of the drive rod. That is, when a current flows through the coil, the armature is magnetized and vi...
