A linear compressor includes a compressor body configured to compress a refrigerant. The compressor body includes a cylinder, a discharge valve, a groove, a gas hole, and a flow restrictor. The cylinder receives a piston. The discharge valve is configured to open and close one side of the cylinder and define a compression space for the refrigerant together with the piston. The groove is defined in an outer circumferential surface of the cylinder and into which at least a portion of the refrigerant discharged through the discharge valve is introduced. The gas hole is defined in the groove to pass through the cylinder. The flow restrictor includes twisting wires made of different materials and is disposed to be wound around the groove.

Linear compressor

A mobile terminal includes: a case unit including a plurality of case parts; a waterproof member that waterproofs the plurality of case parts; an inner space formed by the plurality of case parts and the waterproof member; a sound output unit in the inner space; an electronic component in the inner space; at least one processor controlling the sound output unit; a resonance space in the inner space that resonates sound from the sound output unit; and a sound hole at one side of the case unit that outputs a first sound. A sound pressure level of a second sound output by vibration of the case unit due to the first sound is higher than that of the first sound in a low-frequency range, and when the case unit is on a mounting surface, a third sound is generated by the mounting surface due to vibration of the second sound.

Mobile terminal

There is disclosed a mobile terminal comprising a body; a display unit disposed on a front surface of the body and having elasticity; a vibration receiver attached to a rear surface of the display unit; a speaker having a higher output than the vibration receiver and configured to transmit sound to a distant location; and a controller configured to vibrate the display unit by driving the vibration receiver according to an audio signal.

A linear compressor is provided. The linear compressor may include a cylinder including a cylinder body that defines a compression space for a refrigerant and a cylinder flange that extends from the cylinder body in a radial direction; a piston that reciprocates within the cylinder in an axial direction; and a frame coupled to the cylinder. The frame may include a frame body into which the cylinder body may be inserted and a first press-fitting portion press-fitted into the cylinder flange.

A linear compressor is provided that may include a shell; a compressor body accommodated in the shell to compress a refrigerant; a discharge cover assembly through which the refrigerant compressed in the compressor body may be discharged; a cover pipe that extends from the discharge cover assembly to discharge the refrigerant discharged into the discharge cover assembly to an outside of the discharge cover assembly; a discharge pipe coupled to the shell to discharge the refrigerant flowing along the cover pipe to an outside of the shell; a loop pipe having a first end connected to the cover pipe and a second end connected to the discharge pipe; and a coupling member that respectively couples both the first and second ends of the loop pipe to the cover pipe and the discharge pipe. The coupling member may include a connection member, a first portion of which is inserted into the loop pipe and a second portion of which is inserted into the discharge pipe or the cover pipe. The connection member may be formed of a steel material. At least one of the discharge pipe or the cover pipe may be formed of a steel material.

A linear compressor is provided. The linear compressor may include a cylinder; a frame coupled to an outer side of the cylinder; a cylinder groove defined on an outer circumferential surface of the cylinder; and a sealing member provided in the cylinder groove. The sealing member may be provided between the outer circumferential surface of the cylinder and an inner circumferential surface of the frame.

A mobile terminal including a first body; a first audio output unit provided in the first body and configured to output sound; an audio conversion unit provided in the first body and configured to convert a sound source signal into an audio signal; a second body detachably coupled to the first body; and a second audio output unit provided in the second body and configured to output sound, wherein the audio conversion unit converts the sound source signal into a default audio signal and transmits the converted signal to the first audio output unit, in a state where the second body is detached from the first body, and the audio conversion unit converts the sound source signal into a first audio signal and transmits the converted first audio signal to the first audio output unit, when the second body is coupled to the first body.
