Problems solved by technology

Therefore, as the amplitude requirement increases, the height of the vibration space required by the diaphragm assembly of the loudspeaker increases, which indirectly leads to a further increase in the height of the end product.
[0004] However, with the continuous development of thinner and lighter microelectronic equipment, the thickness of mobile terminal equipment is constantly decreasing, so that the amplitude of the micro-speaker cannot be further increased, and the performance cannot be further improved.

Abstract

The invention discloses a loudspeaker. According to the loudspeaker, a vibrating diaphragm assembly is arranged in a shell, the plane where the vibrating diaphragm assembly is located is parallel to the thickness direction of the shell, and a vibrator assembly is connected with the vibrating diaphragm assembly through a linkage device, so that when interaction force is generated between a stator assembly and the vibrator assembly to enable the vibrating diaphragm assembly to vibrate, the vibrating diaphragm assembly can vibrate in the form of being perpendicular to the thickness direction of the shell, and a vibration mode taking the thickness direction as the vibration direction is avoided, so that the amplitude is not limited due to the lightening and thinning of equipment such as a mobile terminal, the maximum amplitude of the vibrating diaphragm assembly can reach more than 0.8 mm, the improvement of the performance of the loudspeaker is facilitated, and he acoustic performance of the loudspeaker is improved in a light and thin terminal.

Description

technical field [0001] The invention relates to the technical field of electroacoustic products, in particular to a loudspeaker. Background technique [0002] Speakers and receivers currently used in mobile terminals are popularizing large-amplitude speakers or super-linear speakers. Therefore, the amplitude of the speaker and receiver is gradually increased from the original 0.50mm to 0.65mm and 0.75mm until the amplitude required by the current ultra-linear speaker or large-amplitude device reaches above 0.8mm. [0003] However, the vibration direction of the diaphragm assembly of the existing loudspeaker is: the direction perpendicular to the horizontal direction when the mobile terminal device is placed flat, that is, the thickness direction of the mobile terminal device. Therefore, as the amplitude requirement increases, the height of the vibration space required by the diaphragm assembly of the loudspeaker increases, which indirectly leads to a further increase in the...
