Description

Technical Field

[0001] The utility model relates to the technical field of loudspeakers, and particularly relates to a loudspeaker with a double magnetic circuit and double voice coil structure. Background Art

[0002] A loudspeaker is a transducer device that converts electrical signals into sound signals. The performance of a loudspeaker has a great impact on the sound quality. The loudspeaker is the weakest component in audio equipment, but for the audio effect, it is the most important component. There are a wide variety of loudspeakers, and the prices vary greatly. Audio electrical energy makes its paper cone or diaphragm vibrate through electromagnetic, piezoelectric or electrostatic effects, and resonates with the surrounding air to emit sound.

[0003] The published patent No. CN213213776 discloses a loudspeaker structure. The patent reasonably sets through holes, annular positioning parts, annular grooves, sound guiding grooves, welding point grooves, positioning notch parts, and first air vent hole structures on both end faces of the loudspeaker bracket, so that the production work of the loudspeaker bracket can be completed only by one positioning, saving production time and improving production efficiency. The utility model adopts the technical means of reasonably setting the structure of the loudspeaker bracket, overcomes the technical problem of inconvenient clamping of the loudspeaker bracket, and achieves the technology of convenient clamping and positioning of the loudspeaker bracket. However, the following problems still exist in the actual use of this patent:

[0004] By adopting the technical means of reasonably setting the structure of the loudspeaker bracket, the technical problem of inconvenient clamping of the loudspeaker bracket is overcome, and the technology of convenient clamping and positioning of the loudspeaker bracket is achieved. However, the overall loudspeaker is a single magnetic circuit and single voice coil structure. When the single magnetic circuit and single voice coil loudspeaker works, only one electromagnetic structure can emit sound, and it is always in a single sound membrane state, and the sound quality of the loudspeaker is not ideal enough.

[0005] A loudspeaker with a double magnetic circuit and double voice coil structure is proposed to solve the problems mentioned above. Content of the Utility Model

[0006] The purpose of the utility model is to provide a loudspeaker with a double magnetic circuit and double voice coil structure to solve the problem that although the technical problem of inconvenient clamping of the loudspeaker bracket is overcome by adopting the technical means of reasonably setting the structure of the loudspeaker bracket and the technology of convenient clamping and positioning of the loudspeaker bracket is achieved, the overall loudspeaker is a single magnetic circuit and single voice coil structure. When the single magnetic circuit and single voice coil loudspeaker works, only one electromagnetic structure can emit sound, and it is always in a single sound membrane state, and the sound quality of the loudspeaker is not ideal enough as mentioned in the above background art.

[0007] To achieve the above purpose, the utility model provides the following technical scheme: A loudspeaker with a double magnetic circuit and double voice coil structure, including a housing;

[0008] An installation ring is provided at the outer top of the housing, and a first U-shaped iron is provided at the bottom of the housing. A connecting plate is fixedly installed outside the first U-shaped iron, and the connecting plate is fixedly connected to the housing;

[0009] It further includes:

[0010] A diaphragm is fixedly connected to the lower part inside the housing, and a first magnet is fixedly installed inside the first U-shaped iron. A first washer is fixedly installed on the top of the first magnet;

[0011] Wherein, a first voice coil is sleeved outside the first washer, and a middle magnet is fixedly installed on the top of the first washer;

[0012] Wherein, a second U-shaped iron is arranged above the middle magnet, and a second magnet is fixedly installed inside the second U-shaped iron.

[0013] Preferably, a second washer is fixedly installed on the bottom of the second magnet, and a second voice coil is sleeved outside the second washer.

[0014] Preferably, a dust cap is fixedly installed inside the housing outside the middle magnet.

[0015] Compared with the prior art, the beneficial effects of the present utility model are as follows: For the speaker with a dual magnetic circuit and dual voice coil structure, through the symmetrically arranged upper and lower magnetic circuits and voice coils, the two magnetic circuits and voice coils jointly drive the dust cap to vibrate, improving the sound generation efficiency, which can improve the sound quality of the speaker. And under the same driving power, the two magnetic circuits and voice coils work together, saving energy consumption and enhancing the practicability. The specific content is as follows:

[0016] 1. When the speaker emits sound, the first U-shaped iron forms a lower magnetic circuit through the first magnet and the first washer, and forms a lower voice coil through the first voice coil. The second U-shaped iron forms an upper magnetic circuit through the second magnet and the second washer, and forms an upper voice coil through the second voice coil. The two magnetic circuit structures can be connected through the middle magnet, enabling the two magnetic circuit structures to work together, so that the two magnetic circuits and voice coils jointly drive the dust cap to vibrate, improving the sound generation efficiency, which can improve the sound quality of the speaker. And under the same driving power, the two magnetic circuits and voice coils work together, saving energy consumption and enhancing the practicability. Because it pushes the dust cap from both the upper and lower aspects, it can reduce deformation and incoordination, achieving the effect of reducing distortion and improving sound quality; this structure also saves more installation space and is lighter in weight, suitable for uses such as electric vehicle doors.
