Abstract
A structure includes a sound-generating element, a first combining member, a plurality of second vibration membranes, a plurality of spacing portions, a vibration space, and a sound-absorbing element. Based on the structure, the arrangement of the first and second vibration membranes can enhance musicality of low frequencies of the sound-generating element and can also ensure the clearness of middle and high frequencies to allow most of the hearing impaired to clearly hear, and this, together with the arrangement of a combination curvature and spacing portions, makes the transmission path of sound waves wider and also makes the sound more transmittable, while the sound-absorbing element provides dual functions of noise reduction and supporting to the second vibration membranes.
Claims1
A structure of loudspeaker, mainly comprising:
- a sound-generating element, of which a surface comprises a first vibration membrane;
- a first combining member, which is arranged on the sound-generating element and abuts a center of the first vibration membrane;
- a plurality of second vibration membranes, ends of the second vibration membranes being circumferentially arranged on the first combining member, each of the second vibration membranes being curved to form multiple sections of a combination curvature, the combination curvature comprising a first curvature adjacent to the first combining member, at least one second curvature defined on one side of the first curvature that is away from the first combining member, and a third curvature defined on one side of the second curvature that is away from the first curvature;
- wherein the first combining member comprises at least one combining surface to correspondingly combine with the second vibration membranes and not parallel with combining portions of the second vibration membranes adjacent thereto;
- a plurality of spacing portions, which are defined between adjacent ones of the second vibration membranes;
- a vibration space, which is formed by being surrounded by curving of the second vibration membranes;
- wherein the sound-generating element comprises a support element that extends through the vibration space, and one end of the support element that is away from the sound-generating element is arranged for mounting ends of the second vibration membranes that are away from the first combining member;
- and
- a sound-absorbing element, which is arranged in an interior of the vibration space for noise reduction and supporting of the second vibration membranes.
