Embodiment Construction

[0019] The present invention will be further described in detail below in conjunction with the accompanying drawings and specific embodiments.

[0020] Such as Figure 1 to Figure 4 As shown, the multifunctional loudspeaker disclosed in the present invention includes a vibration system, a magnetic circuit system and a peripheral frame. Wherein, the vibration system includes a first diaphragm 21 and a voice coil 22 combined with the lower side of the first diaphragm 21 , and the voice coil 22 drives the first diaphragm 21 to vibrate to produce sound during operation. The magnetic circuit system includes a washer 31, a magnet 32 ​​and a basin frame 33 combined in sequence. A second diaphragm 23 supporting the magnetic circuit system is provided on the underside of the magnetic circuit system. The second diaphragm 23 is fixedly combined with the basin frame 33. The magnetic circuit system of the invention can be used as a vibrator to vibrate, and the second diaphragm 23 can foll...

Abstract

The invention discloses a multi-functional loudspeaker which comprises a vibrating system, a magnetic circuit system and a peripheral framework for accommodating and fixing the vibrating system and the magnetic circuit system. The vibrating system comprises a first vibrating diaphragm and a voice coil combined with one side of the first vibrating diaphragm. The magnetic circuit system forms a magnetic gap for accommodating the voice coil. The vibrating system further comprises a second vibrating diaphragm for supporting and fixing the magnetic circuit system, and the second vibrating diaphragm is arranged inside the multi-functional loudspeaker at a position opposite to the first vibrating diaphragm. a leaking hole for communicating the inside of the multi-functional loudspeaker and the outside is arranged on a portion between the first vibrating diaphragm and the second vibrating diaphragm on the peripheral framework.

Description

technical field [0001] The invention relates to the field of electroacoustics, in particular to a multifunctional loudspeaker. Background technique [0002] At present, multifunctional speakers with a vibration function are widely used, and the multifunctional speakers with this structure have both the functions of a speaker and a vibration motor. The multifunctional loudspeaker includes a vibration system, a magnetic circuit system and a casing. The vibration system includes a diaphragm and a voice coil. When the diaphragm vibrates, sound can be generated. The magnetic circuit system usually includes a magnet and a magnetically conductive pot frame. The magnetic circuit system forms a voice coil. magnetic gap. The magnetic circuit system in the multi-functional loudspeaker is not fixed on the casing as a vibrator, but is fixedly supported by an elastic support member, and the magnetic circuit system generates vibration when it vibrates. Due to the low resonant frequency o...
