The present disclosure relates to the field of vibratory sounding techniques and, particularly, relates to a spring sheet, an electroacoustic device containing the spring sheet and an electronic device containing the electroacoustic device.
With the rapid development of electronic information technologies, more and more electroacoustic devices are applied in electronic products of various types and, particularly, in the mobile communication equipment widely used in people's life. Not only miniaturization and multifunction of the electroacoustic device have been concerned, but also sound effect with high quality and no sound distortion are highly demanded.
Generally, a spring sheet used in a conventional electroacoustic device is an unenclosed structure, however, such spring sheet cannot effectively resolve the stress of the spring sheet, and thus deformation readily occurs when the product falls off.
In view of this, it is necessary to provide a new spring sheet.
Many aspects of the exemplary embodiment can be better understood with reference to the following drawings. The components in the drawings are not necessarily drawn to scale, the emphasis instead being placed upon clearly illustrating the principles of the present disclosure.
The drawings herein are incorporated in the specification and form one section of the specification, which have shown embodiments of the present disclosure and are used together with the specification to explain the principle of the present disclosure.
The present disclosure will be described in further detail with reference to the following embodiments and the accompanying drawings.
As shown in
Since the main body 110 is constructed in a non-circular enclosed ring, the spring sheet 100 of the present embodiment can be applied in a non-circular three-in-one product, and such a non-circular enclosed ring structure can also effectively disperse the stress of the spring sheet 100, which can fundamentally solve the problem that the arm of force of the spring sheet deforms and loses efficacy when the non-circular three-in-one product falls off, thereby extending the service life of the spring sheet 100. As for a product using the spring sheet 100, for example, an electroacoustic device 200, since the spring sheet 100 can effectively disperse the stress, the service life of the electroacoustic device 200 can also be extended, thereby reducing the cost.
It should be noted that, the present disclosure has no limitation on the specific configuration of the main body 110, as long as it is shaped in an enclosed ring and is non-circular. For example, the main body 110 may be quadrilateral or even polygonal, etc.
The configuration of the electroacoustic device 200 can refer to the second aspect of the present embodiment, which is not repeated herein.
