The present disclosure relates to vibration plates having a reinforced structural element. More particularly, the present disclosure relates to vibration plates utilized in speakers.
Music is an important product of human civilization. With the improvement of living standards of people, the types of equipment related to music have become more and more diverse. Among those equipment, speaker is an important device which can greatly increase the sound volume. Apart from the applications in music, users can also use speakers to allow more listeners to hear the message that the users wants to deliver.
However, apart from effectively amplifying the sound volume, how to avoid distortion of the amplified sound is undoubtedly a topic of great concern in the industry.
A technical aspect of the present disclosure is to provide a vibration plate having a reinforced structural element and being particularly utilized in a speaker. The reinforced structural element can effectively maintain the shape of the vibration plate, such that the chance of sound distortion of the speaker is reduced.
According to an embodiment of the present disclosure, a vibration plate having a reinforced structural element is provided. The vibration plate includes a vibration plate main body. The vibration plate main body has a first surface and a second surface opposite to each other. The reinforced structural element is located between the first surface and the second surface. A material of the vibration plate main body is different from a material of the reinforced structural element.
In one or more embodiments of the present disclosure, the material of the vibration plate main body includes one of paper, polypropylene, rubber, ceramic, glass fiber, aluminum, titanium, beryllium, magnesium-lithium alloy or any combination thereof.
In one or more embodiments of the present disclosure, the material of the reinforced structural element includes one of carbon fiber, mica, titanium, magnesium-lithium alloy or any combination thereof.
In one or more embodiments of the present disclosure, the reinforced structural element is in a shape of a cylinder.
In one or more embodiments of the present disclosure, the reinforced structural element has a cross-sectional diameter ranging between 0.5 mm and 1.5 mm.
In one or more embodiments of the present disclosure, the reinforced structural element extends towards a center of the vibration plate main body.
In one or more embodiments of the present disclosure, an extension direction of the reinforced structural element deviates from a center of the vibration plate main body.
In one or more embodiments of the present disclosure, the reinforced structural element is in a shape of a flake.
In one or more embodiments of the present disclosure, the reinforced structural element has a thickness ranging between 0.1 mm and 1.0 mm.
In one or more embodiments of the present disclosure, the reinforced structural element is in a shape of a curve or a circle.
In one or more embodiments of the present disclosure, the reinforced structural element includes a first subsidiary reinforced structural element and a second subsidiary reinforced structural element, the first subsidiary reinforced structural element extends towards a center of the vibration plate main body, the second subsidiary reinforced structural element is in a shape of a curve, the first subsidiary reinforced structural element connects to a portion of the second subsidiary reinforced structural element between two ends of the second subsidiary reinforced structural element.
According to an embodiment of the present disclosure, a speaker includes a base frame and a vibration plate. The vibration plate is disposed above the base frame. The vibration plate includes a vibration plate main body and a reinforced structural element. The vibration plate main body has a first surface and a second surface opposite to each other. The reinforced structural element is located between the first surface and the second surface. A material of the vibration plate main body is different from a material of the reinforced structural element.
When compared with the prior art, the above-mentioned embodiments of the present disclosure have at least the following advantages:
(1) Through embedding the reinforced structural element inside the vibration plate, the overall stiffness of the vibration plate can be reinforced. Therefore, during the operation of the speaker, when the magnetic assembly unit makes a sound and the vibration plate at least partially vibrates, the degree of deformation of the vibration plate is effectively reduced. In other words, the shape of the vibration plate can be effectively maintained, such that the chance of sound distortion of the speaker is reduced.
(2) Since the reinforced structural element is embedded inside the vibration plate, the chance of peeling off of the reinforced structural element from the vibration plate is effectively avoided.
(3) Since a carbon fiber stick has a very light weight, the carbon stick is appropriate to be embedded inside the vibration plate main body while the overall weight of the vibration plate is not greatly increased, which effectively maintains the property of the vibration plate.
The disclosure can be more fully understood by reading the following detailed description of the embodiments, with reference made to the accompanying drawings as follows:
Drawings will be used below to disclose embodiments of the present disclosure. For the sake of clear illustration, many practical details will be explained together in the description below. However, it is appreciated that the practical details should not be used to limit the claimed scope. In other words, in some embodiments of the present disclosure, the practical details are not essential. Moreover, for the sake of drawing simplification, some customary structures and elements in the drawings will be schematically shown in a simplified way.

In practical applications, for instance, the material of the vibration plate main body 133 includes one of paper, polypropylene, rubber, ceramic, glass fiber, aluminum, titanium, beryllium, magnesium-lithium alloy or any combination thereof.
On the other hand, for instance, the material of the reinforced structural element 135 includes one of carbon fiber, mica, titanium, magnesium-lithium alloy or any combination thereof. As mentioned above, the material of the vibration plate main body 133 is different from the material of the reinforced structural element 135. Therefore, the vibration plate main body 133 and the reinforced structural element 135 cannot be chosen to have the same material.
In addition, the base frame 110 has a base plate 111 and a side wall 112 connected with each other. The side wall 112 surrounds to define a space S. As shown in
Through embedding the reinforced structural element 135 inside the vibration plate 130, the overall stiffness of the vibration plate 130 can be reinforced. Therefore, during the operation of the speaker 100, when the magnetic assembly unit 121 makes a sound and the vibration plate 130 at least partially vibrates, the degree of deformation of the vibration plate 130 is effectively reduced. In other words, the shape of the vibration plate can be effectively maintained, such that the chance of sound distortion of the speaker 100 is reduced.
