Description

Technical Field

[0001] The utility model relates to the technical field of electronic equipment, and more specifically, to an inner and outer double-magnetic loudspeaker. Background Art

[0002] A speaker is a transducer that converts electrical signals into sound signals. The performance of a speaker has a great impact on the sound quality. The speaker is the weakest component in audio equipment, but it is also the most important component for sound effects. There are many types of speakers, and their prices vary greatly. Audio electrical energy vibrates the cone or diaphragm through electromagnetic, piezoelectric or electrostatic effects, and resonates (resonates) with the surrounding air to produce sound.

[0003] Existing speakers cannot adjust high and low frequencies well. If the high frequencies are not enough, the high frequencies are generally enhanced, but this is difficult and costly. In addition, the traditional method of adjusting the high and low frequencies of speakers is prone to sound distortion, affecting the user experience.

[0004] After searching, the Chinese patent with publication number CN215818598U discloses an internal and external dual-magnet speaker. The dynamic coil unit of the utility model is accommodated in a cavity formed between the top cover and the surface cover. The internal magnet and the external magnet are placed inside and outside the T-iron to separate the internal magnet and the external magnet. The sum of the number of the internal magnets and the external magnets is more than three. When there is at least one internal magnet and at least two external magnets, the two external magnets are stacked up and down so that there is a height difference between the two external magnets. Since the magnetic forces of the two external magnets are different, a torque ratio will be generated, thereby changing the audio, making the high and low frequencies of the audio clearer and the hearing effect better.

[0005] However, when the dual-magnetic speaker is actually used, an inadvertent touch when placing the speaker may cause the speaker to topple over, which may have a certain impact on the speaker and may cause damage to the electronic components of the speaker, thus affecting the service life of the speaker.

[0040] The embodiment of the present application discloses an internal and external dual-magnet speaker, specifically comprising two internal and external dual-magnet speaker bodies 11 arranged on the front side of the speaker, two card slots 2 arranged inside the speaker, and two balance locking mechanisms fixedly connected to the inner wall of the speaker;

[0041] The balancing locking mechanism includes a bottom block 3, a limiting tube 4 is fixedly connected to the front side of the bottom block 3, a first spring 5 is movably connected inside the limiting tube 4, a slider 6 is movably connected to the front side of the first spring 5, a guide hole 7 is arranged inside the slider 6, blocks 8 are fixedly connected to both sides of the outside of the limiting tube 4, second springs 9 are movably connected inside the two blocks 8, one end of the two second springs 9 are fixedly connected to limiting columns 10, two inner and outer dual-magnetic speaker bodies 11 are movably connected to the front side of the speaker box, a fixing tube 12 is fixedly connected to the rear sides of the two inner and outer dual-magnetic speaker bodies 11, the two blocks 8 on the outside of the limiting tube 4 can be threadedly connected to the threaded groove 13 inside the fixing tube 12, so that the fixing tube 12 and the limiting tube 4 can be quickly fixed, and at the same time, the inside of the threaded groove 13 is continued to be fixed by the two second springs 9 and the limiting column 10 to prevent the fixing tube 12 and the limiting tube 4 from loosening.

[0042] Reference Figure 5As shown, specifically, the inner walls of the two fixing tubes 12 are both provided with thread grooves 13 , and the insides of the two fixing tubes 12 are fixedly connected with plug posts 14 to assist in guiding the connection of the inner and outer dual-magnetic speaker bodies 11 .

[0043] Reference Figure 4 As shown, specifically, multiple movable seats 15 are fixedly connected to the outer sides of the two inner and outer dual-magnetic speaker bodies 11, and the multiple movable seats 15 are arranged in a circular array on the outer sides of the two inner and outer dual-magnetic speaker bodies 11; transmission arms 16 are movably connected to the outer sides of the multiple movable seats 15; balance connecting rods 17 are movably connected to the front ends of the multiple transmission arms 16; guard plates 18 are fixedly connected to the outer sides of the multiple balance connecting rods 17; the multiple guard plates 18 are distributed in a circular array on the outer sides of the two inner and outer dual-magnetic speaker bodies 11; multiple buffer blocks 19 are fixedly connected to the outside of the two inner and outer dual-magnetic speaker bodies 11, which provide a certain buffer for the inner and outer dual-magnetic speaker bodies 11 and reduce the impact of the tipping of the speaker box on the inner and outer dual-magnetic speaker bodies 11.

[0044] The working principle of the utility model is as follows: when assembling the inner and outer dual-magnetic speaker body 11 into the interior of the sound box, first insert the inner and outer dual-magnetic speaker body 11 and multiple outer guard plates 18 through the opening on the front side of the sound box, then align the fixing tube 12 on the rear side of the inner and outer dual-magnetic speaker body 11 with the guide hole 7 on the front side of the slider 6 inside the limiting tube 4, rotate the inner and outer dual-magnetic speaker body 11 and the fixing tube 12 to fit the two clamping blocks 8 on the front side of the limiting tube 4 with the inner wall of the thread groove 13, and during the rotation process, the two clamping blocks 8 enter the interior of the fixing tube 12 along the thread groove 13, and when the two clamping blocks 8 enter the innermost of the thread groove 13, the two limiting columns 10 are pushed by the two second springs 9 to The groove inside the thread groove 13 is clamped to prevent the threaded connection between the thread groove 13 and the clamping block 8 from loosening.
