Embodiment Construction

[0062] In order to fully understand the purpose, features and effects of the present invention, the present invention will be described in detail by means of the following specific embodiments and accompanying drawings, as follows:

[0063] Please refer to Figure 1 to Figure 4 , as shown in the figure, the present invention provides a loudspeaker, especially a thin loudspeaker suitable for a thickness of less than 2 cm, which includes a support frame 1 , at least one driving unit 2 and a diaphragm unit 3 .

[0064] The driving unit 2 is disposed in the support frame 1 , and the driving unit 2 includes a magnetic return member 21 and a voice coil 22 , and the magnetic return member 21 is movably sleeved with the voice coil 22 .

[0065] The diaphragm unit 3 combines the support frame 1 and the drive unit 2. The diaphragm unit 3 includes a first diaphragm 31, a second diaphragm 32, and a third diaphragm 33. The first diaphragm 31 is ring-shaped, and the first diaphragm 31 Ther...

Abstract

The invention provides a loudspeaker. The loudspeaker comprises a supporting frame, a driving unit arranged on the supporting frame, and a vibration film unit combining the supporting frame with a sound ring; the driving unit comprises a magnetic returning component and the sound ring, and the sound ring is arranged outside the magnetic returning component as a moving sleeve; the vibration film unit comprises a first vibration film, a second vibration film and a third vibration film; the first vibration film is a ring, and the first vibration film has a first cliff edge; the second vibration film has a second cliff edge, the second cliff edge is under the first cliff edge, and a vibration space is formed between the second cliff edge and the first cliff edge; and the third vibration film is connected with the first vibration film and the second vibration film. According to the invention, the first vibration film, the second vibration film and the third vibration film are arranged to increase the effective acoustic area of the loudspeaker vibration film, therefore, the volume is improved, the bass performance is better, and the distortion is slowed down.

Description

technical field [0001] The present invention provides a loudspeaker, especially a loudspeaker with a first diaphragm, a second diaphragm and a third diaphragm, so as to increase the effective sound-generating area of ​​the diaphragm, thereby enhancing volume, better bass performance and slowing down The effect of distortion. Background technique [0002] As today's consumer electronic products are generally moving toward thinner and lighter designs, the built-in speaker units must also adopt a thinner and lighter miniaturized design. Therefore, how to miniaturize the speaker without sacrificing sound quality and volume output has become a The main topic of microspeaker design at present. [0003] In order to improve the sound quality and volume output of the micro-speaker, the size of the micro-speaker is mainly rectangular, and the rectangular diaphragm is used to maximize the sound-emitting area of ​​the diaphragm to improve the performance of sound quality and volume. At...
