Abstract

The invention provides a loudspeaker structure which comprises a washer, a first magnet, T-shaped iron and at least two voice coils, wherein the first magnet is arranged in the middle of the washer, and through holes are arranged at two ends; the shape of the T-shaped iron is identical to that of the washer, two ends of the T-shaped iron are protruded, the protruding parts are respectively sleeved in the through holes at two ends of the washer; and the first magnet is clamped between the washer and the T-shaped iron, and the voice coils are respectively sleeved on the protrusions of the washer. The magnet and the voice coils are not on the same axial line, but the T-shaped iron contacted with the magnet and the washer transmit magnetic induction linesto magnetic gaps to provide energy for vibration of the voice coils; the height space of the loudspeaker can be utilized to the largest extent, horns and voice boxes can be thinner and minimized, simultaneously the shape of the magnet does not need to be corresponding to or similar to that of the voice coils, and processing cost is simplified.

Description

technical field [0001] The invention relates to the mechanical field, in particular to a loudspeaker structure. Background technique [0002] The magnetic circuit structure used in traditional loudspeakers is usually that the voice coil and the magnetic circuit are on the same axis, such as Figure 1-Figure 5 As shown, the labels are T-shaped iron 2A, 2B, magnet 3A, 3B, 3C, washer 4A, 4B, voice coil 8A, 8B, 8C, the magnets are symmetrically distributed along the axis of the voice coil, and the magnets are usually inside the voice coil called internal magnetism (see figure 2 and Figure 4 ), outside the voice coil is called the external magnet (see figure 1 and image 3 ). The shape of the voice coil is similar to the shape of the magnet. If the voice coil is circular, the magnet is usually also circular; since the magnet part is in the axial direction of the voice coil and at the bottom of the voice coil (such as image 3 , Figure 4 and Figure 5 As shown), the str...
