Embodiment Construction
[0015] Below, the substantive features and advantages of the present invention will be further described in conjunction with examples, but the present invention is not limited to the listed examples.
[0016] Such as figure 1 and figure 2 As shown, the novel loudspeaker 100 of this embodiment includes an upper casing 1 , a first magnet 2 , a positioning element 3 , a magnetostrictive element 4 , an audio coil 5 , a second magnet 6 and a lower casing 7 . An accommodating portion 11 is provided in the upper casing 1 , and the first magnet 2 is disposed in the accommodating portion 11 and abuts against the upper casing 1 . The positioning member 3 is disposed in the accommodating portion 11 and presses the first magnet 2 . The positioning member 3 is provided with a through hole portion 30 , and the magnetostrictive element 4 passes through the through hole portion 30 . The second magnet 6 is arranged below the positioning member 3, and the two ends of the magnetostrictive me...

The invention relates to a novel loudspeaker. The loudspeaker comprises an upper housing body, a first magnet, a positioning piece, a magnetic induced elastic piece, an audio coil, a second magnet anda lower housing body. An accommodation part is arranged in the upper housing body. The first magnet is arranged on the accommodation part and is abutted against the upper housing body. The positioning piece is arranged in the accommodation part and presses the first magnet. A through hole part is arranged on the positioning part. The magnetic induced elastic piece is arranged in the through holepart in a threading manner. The second magnet is arranged under the positioning piece. Two ends of the magnetic induced elastic piece are abutted against the first magnet and the second magnet. The audio coil is wound around the outer surface of the positioning piece. A storage part is arranged on the lower housing body and is abutted against the second magnet. The upper housing body is connectedwith the lower housing body. A resonance space is arranged between the upper housing body and the lower housing body. A conduction piece is arranged on the lower housing body. According to the invention, sound is produced through resonance, so the structure of the loudspeaker is simplified; and compared with the traditional loudspeakers, the size is effectively reduced, it is convenient for a userto take the loudspeaker, and the use range of the loudspeaker is extended.
Description
technical field [0001] The present invention relates to a new loudspeaker. Background technique [0002] At present, the principle of sound generation of speakers is to convert electrical energy into mechanical vibration, and then disturb the air to become sound waves. The current flows into the speaker through the wire, the coil in the speaker generates a magnetic field, and a magnet is placed near the coil. When the positive pole is opposite to the positive pole, repulsion is generated, and the diaphragm retracts; when the negative pole is opposite to the positive pole, the diaphragm expands outward, and the vibration is generated by the contraction and expansion of the diaphragm. sound, and then amplify the sound through speakers. The disadvantage of the above-mentioned speaker is that the speaker needs to be used for sound amplification, which increases the manufacturing cost and expands the volume, making it impossible to carry it with you, which limits the range of us...
