Patent Description:
With the development of information and communication technology and semiconductor technology, various functions are packed in one portable electronic device. For example, an electronic device may have not only communication function but also the entertainment function, e.g., playing games, the multimedia function, e.g., playing music/videos, communication and security functions for mobile banking, and scheduling and e-wallet functions. Such electronic devices become compact enough for users to carry in a convenient way.

As mobile communication services expand up to multimedia service sectors, the display of the electronic device may be sized up to support multimedia services as well as voice call or text messaging services.

An electronic device (e.g., a portable terminal) may include a display with a flat surface or both a flat and curved surface. An electronic device including a display may have a limitation in realizing a screen larger than the size of the electronic device due to the fixed display structure. Examples of electronic devices with fixed display structures are described in document <CIT>and <CIT>. Accordingly, research has been conducted on electronic devices including a foldable or rollable display.

An example of an electronic device with a foldable display is disclosed in document <CIT>. Document <CIT> pertains to an example of an electronic device with a rollable display. An example of a microphone component of an electronic device is disclosed in document <CIT>.

As the structures of an electronic device move relative to each other (e.g., a slide), noise or vibration may be generated. For example, when an electronic device with a bendable display slides, the position of the camera, speaker, or microphone may change, and driving noise and/or vibration may be introduced into the microphone.

Accordingly, an aspect of the disclosure is possible to provide a noise detection module capable of detecting driving noise and/or vibration of an electronic device.

Another aspect of the disclosure is to provide an electronic device that may distinguish between noise and voice using a noise detection module including a microphone module and a vibration detection sensor and may attenuate the noise.

The disclosure is not limited to the foregoing embodiments, but various modifications or changes may rather be made thereto without departing from scope of the invention as defined by the claims.

According to various embodiments of the disclosure, the electronic device may detect driving noise and vibration using a noise detection module including a microphone module and a vibration detection sensor capable of detecting vibration of a low frequency band (e.g., <NUM> to <NUM>).

According to various embodiments of the disclosure, the electronic device may reduce noise based on signals obtained from the microphone module and the vibration detection sensor.

Accordingly, those of ordinary skill in the art will recognize that various changes and modifications of the various embodiments described herein can be made without departing from the scope of the invention as defined by the claims.

Accordingly, it should be apparent to those skilled in the art that the following description of various embodiments of the disclosure is provided for illustration purpose only and not for the purpose of limiting the invention as defined by the appended claims.
