Abstract

The invention relates to a loudspeaker structure, which includes a sound film and a plurality of support frames, magnets are arranged on the support frames, and the sound film is arranged between the support frames. The speaker structure also includes a shared support frame, and a shared magnet is arranged on the shared support frame. The sound membrane includes a first sound membrane and a second sound membrane, and a shared support frame is arranged between the first sound membrane and the second sound membrane, and the support frame includes a first support frame and a second support frame, and the first support frame is provided with The first magnet, the second support frame is provided with a second magnet, the first support frame is provided with a first opening, the first sound film is located between the first support frame and the shared support frame, and the first opening faces the first sound film , the second support frame is provided with a second opening, the second sound membrane is located between the shared support frame and the second support frame, and the second opening faces the second sound membrane. The invention uses fewer magnets to realize high-pitched and mid-pitched output, which reduces the manufacturing cost; the structure of the speaker is reduced, thereby reducing the volume of the sound box for accommodating the speaker.

Description

technical field [0001] The invention relates to the technical field of loudspeakers, in particular to a loudspeaker structure. Background technique [0002] The loudspeaker is a transducer device that converts electrical signals into acoustic signals, and the performance of the loudspeaker has a great influence on the sound quality. Among the existing loudspeakers, some emit sound through the sound membrane. When the sound membrane is energized, the current flowing through the circuit on the sound membrane and the magnet generate electromagnetic interaction, so that the air vibrates and emits sound. By changing the sound film circuit, the frequency of the sound can be changed, and the treble or midrange can be emitted. Therefore, when there are multiple high-pitched or mid-range speakers in the sound box, multiple independent speakers need to be arranged at a certain distance, which leads to an increase in the manufacturing cost and volume of the sound box. Contents of th...
