Embodiment Construction

[0043] Hereinafter, specific embodiments will be described in detail with reference to the accompanying drawings. This invention may, however, be embodied in different forms and should not be construed as limited to the embodiments set forth herein. Rather, these embodiments are provided so that this disclosure will be thorough and complete, and will fully convey the scope of the invention to those skilled in the art.

[0044] figure 1 is a schematic diagram of a piezoelectric speaker module according to an exemplary embodiment.

[0045] see figure 1 A piezoelectric speaker module according to an exemplary embodiment includes a piezoelectric device 100 , and a vibration transmission plate 200 extending from at least two side surfaces of the piezoelectric device 100 so as to be spaced from one surface of the piezoelectric device 100 . In the piezoelectric speaker module, sound is amplified in the space between the piezoelectric device 100 and the vibration transmission pla...

Abstract

The present invention provides a portable piezoelectric speaker and an electronic device equipped with the speaker. The portable piezoelectric speaker includes: a body configured to be coupled to and detached from the rear surface of the electronic device; and a piezoelectric speaker. a speaker module coupled to a predetermined region of the body, wherein the piezoelectric speaker module includes a piezoelectric device, and a vibration transmission member provided in contact with at least one region of the piezoelectric device and with the piezoelectric device At least one surface of the electrical device is spaced apart. Therefore, it is possible to amplify the volume of the portable electronic device using the piezoelectric speaker module, and the portable piezoelectric speaker can be made extremely thin and small, and thus easy to carry.

Description

technical field [0001] The present invention relates to a portable piezoelectric speaker, and more particularly, to a portable piezoelectric speaker removably coupled to an electronic device to amplify the volume of the electronic device and an electronic device having the speaker. device. Background technique [0002] Recently, size reduction, slimming and weight reduction are increasingly emphasized in small portable electronic devices that users can carry and use. In addition, it is widely used as a smart phone by adding a multipurpose function that can be suitably used in various multimedia environments or an Internet environment, and a simple communication function. Specifically, the smart phone has a wider screen so that the smart phone can be more properly used in a multimedia environment, and for user convenience, a touch screen that can be driven by touch is commonly used in the smart phone. [0003] Meanwhile, in a portable electronic device capable of reproducin...
