The present invention relates to a wireless earphone, and more particularly to a wireless earphone with a flexible microphone for improving the sensitivity of the microphone in the receiving sound.

Earphones and microphones are mainly used in stereo sound and communication systems. Conventional earphones / microphones take many different forms, such as to be worn over the wearer's head, to the user's ear, or to the user's ear. Earphones / microphones that are worn on the wearer's head are commonly used in home stereos and typically provide a good sound spectrum. In-ear earphones / microphones are commonly used in hands-free receivers for cell phones or walkmen. As technology has advanced, earphones have evolved from conventional streamlined to wireless. Currently very common wireless earphones include infrared earphones, radio frequency (RF) earphones, and Bluetooth earphones. However, the Bluetooth earphone is the first dual wireless earphone that can be used in the market.

Currently available Bluetooth earphones have a unique and compact design. As a result, the microphone included in the earphone is placed at a point far from the user's mouth. In this case, the microphone must be adjusted to have high sensitivity in the received sound. However, since the microphone receives more noise at the same time and requires more complicated circuits to enhance its acoustic reception sensitivity, manufacturing costs are high and are sold at the price of Bluetooth earphones.

Accordingly, the present inventors have endeavored to develop a wireless earphone with a flexible microphone suitable for use in a Bluetooth mobile phone having a music play function. In the wireless earphone, since the sliding unit mounted on the upper part of the upper case of the earphone is provided with a push button, the provided microphone and the sliding unit automatically slide and protrude from the front end of the upper case of the earphone to operate the voice communication unit. Receive sound with high sensitivity to the earphones; When the pushbutton is pressed and when the sliding unit with the microphone is retracted, the voice communication unit is automatically disconnected.

The main object of the present invention is to provide a wireless microphone with a telescopic microphone that protrudes from the front end of the earphone when the pushbutton is pressed to activate the voice communication unit and automatically slides to disengage the voice communication unit when moved to the retracted position. It is to provide earphones.

Another object of the present invention is to provide a wireless earphone with a flexible microphone, which earphone can be conveniently transported and stored in a microphone which is typically arranged in its retracted position.

Still another object of the present invention is to provide a wireless earphone with a flexible microphone, which is prevented from being damaged or damaged when the user inadvertently drops the earphone during use.

To achieve this object, the wireless earphone of the present invention includes an acoustic unit, a circuit unit, a lower case, an upper case, a guide unit, and a sliding unit. The lower case and the upper case are connected to each other, and surround the sound unit and the circuit therebetween. The upper case has a first recess for the guide unit thereon, the recess being for mounting. The sliding unit is mounted on the guide unit, and is slidably moved between the protruding position (or operating position) and the retracted position (or separating position).

The guide unit includes a pair of guide shafts on which an elastic element is mounted, and a sliding element slidably mounted on the guide shaft in front of the elastic element. The sliding element comprises a first support recess at the front end of the lower portion, a second support recess at the rear upper portion, and an axially perforated ear portion at the two axial sides, respectively. The guide shaft extends through the perforated ear of the sliding element and is then mounted to the first recess in the upper case.

The sliding unit includes a sheet, a circuit board, and a cover. The sheet has a first hook for hooking into a second support recess in the top of the sliding element; A first hole is provided in front of the first hook for mounting and hooking the second hook to the first support recess on the sliding element. The circuit board is mounted on a sheet. The cover is connected to the top of the seat and has a button hole for mounting the pushbutton at the set position.

The upper case of the earphone has a second hole for mounting the third hook. The third hook typically has a lower end mounted to the elastic element for urging the third hook upward, and an upper end contacting the pushbutton on the cover of the sliding unit.

When the pushbutton on the sliding unit cover is pressed with little force, the third hook on the upper case is pressed, and the sliding unit automatically slides along the guide shaft of the guide unit to a position protruding from the front end of the upper case, Activate the voice communication unit on the earphone. When the sliding unit is retracted to the upper part of the upper case, the voice communication unit is separated. The sliding unit in the retracted position prevents damage or damage when the earphone is inadvertently dropped during use.
