Embodiment Construction

[0027] The loudspeaker diaphragm structure of the present invention will be described below with reference to the accompanying drawings.

[0028] see image 3 , is a schematic side view of the first embodiment of the loudspeaker of the present invention. The speaker 2 includes a magnetic circuit system 21 and a vibration system 23 . Under the action of the magnetic circuit system 21, the vibration system 23 converts electrical energy into mechanical energy, and then converts into sound energy and radiates into space.

[0029] The magnetic circuit system 21 includes a first magnetic bowl 211 , a first magnetic steel 213 , a second magnetic bowl 215 and a second magnetic steel 217 . The first magnetic bowl 211 is a magnetically permeable element with a receiving space, which includes a bottom wall 2111 and side walls 2113 perpendicular to the bottom wall 2111 . The side wall 2113 is disposed on the same side of the bottom wall 2111 and connected to the bottom wall 2111 . The...

Abstract

The invention relates to a magnetic circuit system and a loudspeaker thereof. The loudspeaker comprises a voice coil and the magnetic circuit system, wherein the magnetic circuit system comprises first magnetic steel, a first magnetic bowl containing the first magnetic steel, second magnetic steel and a second magnetic bowl containing the second magnetic steel, the same poles of the first magnetic steel and the second magnetic steel are arranged opposite at intervals, a magnetic field with parallel magnetic lines of force is formed in an interval area, and the voice coil is placed in the magnetic field. The same poles of the magnetic steel are arranged opposite at intervals, the magnetic steel is arranged in the loudspeaker, the magnetic field with parallel magnetic lines of force is formed, the good linear magnetic field is acquired, the mechanical reliability is improved and the product generation effect is also improved.

Description

technical field [0001] The invention relates to a magnetic circuit system and a loudspeaker using the magnetic circuit system. Background technique [0002] Loudspeakers are electro-acoustic transducers that can convert electrical signals into acoustic signals and radiate them into the air, and are widely used in current electronic products. Loudspeakers usually include three parts: magnetic circuit system, vibration system and support system. The voice coil of the vibration system is energized to generate an induced magnetic field, and the induced magnetic field cooperates with the magnetic field of the magnetic circuit system to generate an upward or downward force, which drives the diaphragm of the vibration system to vibrate and pushes the air to produce sound. [0003] see figure 1 , is a schematic side structure diagram of a loudspeaker related to the present invention. The speaker 1 includes a magnetic circuit system 11 , a vibration system 13 and a support system ...
