An electronic device according to various embodiments of the disclosure may include a housing including a first plate forming an outer face. The first plate may include a glass plate including a first surface outwardly facing the housing and a second surface inwardly facing the housing, a coating layer including an anti-reflection coating and/or an anti-finger coating above the first surface while forming the outer face, a first layer formed between the first surface of the first glass plate and the coating layer, having a first thickness, and including a first inorganic material, a second layer formed between the first layer and the coating layer, having a second thickness, and including a second inorganic material different from the first inorganic material, a third layer formed between the second layer and the coating layer, having a third thickness thicker than each of the first thickness and the second thickness, and including a third inorganic material, and an opaque layer formed on the second surface. Various other embodiments may also be possible.

Electronic device comprising high hardness color structure layer

A rear cover of an electronic device is provided. The rear cover includes a glass substrate including a first face facing a first direction, a second face facing a second direction opposite to the first direction, and at least one side face disposed between the first face and the second face, a roughness layer formed on the first face and having a first roughness, a hairline pattern formed on the roughness layer and having a second roughness, and a hard coating layer formed on the roughness layer and the hairline pattern.

Cover of electronic device, and method for manufacturing same

An electronic device is provided. The electronic device includes a housing including a first surface facing in a first direction, a second surface facing in a second direction opposite to the first direction, and a side surface member enclosing the first surface and the second surface, a display visible through at least a portion of the first surface, an opening formed on a portion of the first surface, a speaker positioned within the housing, a sensor positioned within the housing, and a first path configured to guide a sound of the speaker to the opening, and a second path configured to guide the sound of the speaker to the opening and to avoid overlapping the first path, and at least a portion of the sensor is positioned between the first path and the second path.

Portable terminal having speaker and acoustic output path for speaker

A method of filtering a target transmission ratio of a continuously variable transmission of a vehicle includes: controlling, by a controller, a vehicle speed filter configured to filter a speed signal of a vehicle distorted due to vibration of the vehicle; controlling, by the controller, a target driving pulley speed memory configured to output a target driving pulley speed signal of the continuously variable transmission based on an output value of an acceleration pedal sensor and the filtered speed signal of the vehicle; and controlling, by the controller, a transmission calculator configured to calculate a target transmission ratio of the continuously variable transmission that is a stable value based on the target driving pulley speed signal of the continuously variable transmission and the filtered speed signal of the vehicle, wherein the vehicle speed filter increases filtering capability and a response speed of the vehicle speed filter and decreases the speed signal of the vehicle to a value that makes the target transmission ratio of the continuously variable transmission stable.
