1. Technical Field
The present disclosure relates to switching systems, and particularly to a switching system with a wireless earphone.
2. Description of Related Art
Hand-held electronic devices, such as mobile phones, always include a earphone for listening to music or receiving a call. By pressing one or more buttons of the earphone, the hand-held electronic devices can switch between “playing music” function and “receiving a call” function. However, when both hands of a user are occupied with something else such as driving a car, it may be inconvenient for the user to press the button on the earphone to switch the functions of the electronic device.
Therefore, there is room for improvement in the art.
Many aspects of the embodiments can be better understood with references to the following drawings. The components in the drawings are not necessarily drawn to scale, the emphasis instead being placed upon clearly illustrating the principles of the embodiments. Moreover, in the drawings, like reference numerals designate corresponding parts throughout two views.

The earphone 10 is portable. The earphone 10 detects rotations of the earphone 10 and controlling the operations of the electronic device 20 based on the detected rotations. The earphone 10 includes a sensing unit 12, a determining unit 13, a calculating unit 14, a comparing unit 15, a communication unit 17, and a playing unit 19.
The sensing unit 12 is used for detecting whether the rotations of the earphone 10 is in a predetermined direction and generating a direction signal if the rotation of the earphone 10 is in a predetermined direction. In the embodiment, the sensing unit 12 is a gyro sensor and the sensing unit 12 defines a first predetermined direction and a second direction. When the earphone 10 rotates in a first predetermined direction, the sensing unit 12 generates a first signal. When the earphone 10 rotates in a second predetermined direction different from the first predetermined direction, the sensing unit 12 generates a second signal. When the sensing unit 12 generates the first signal and the second signal continuously and alternatively, one of the first signals or the second signals which is first detected is determined to be the direction signal. For example, the earphone 10 first rotates in the first predetermined direction, and then rotates back in the second predetermined direction. The sensing unit 12 first generates a first signal according to the rotation of the earphone 10 in the first predetermined direction, and then generates a second signal according to the rotation of the earphone 10 in the second predetermined direction. Because the sensing unit 12 first generates the first signal, the first signal is determined to be the direction signal. The sensing unit 12 further detects the rotations of the earphone 10 to obtain a rotating angle of the earphone 10.
The determining unit 13 is used for determining whether the obtained rotating angle is at least a predetermined angle and generating a rotating signal when the rotating angle is at least the predetermined angle. In the embodiment, the predetermined angle can be set by the user.
The calculating unit 14 is used for calculating the number of the generated rotating signals during a predetermined time. In the embodiment, the predetermined time can be set by the user.
The comparing unit 15 is used for comparing the number with a predetermined value and generating control signals based on the comparing result. In the embodiment, when the number of the generated rotating signal is less than the predetermined value, the comparing unit 15 generates a first control signal. When the number of the generated rotating signal is at least the predetermined value, the comparing unit 15 generates a second control signal.
The communication unit 17 is used for transmitting control signals and direction signals to the electronic device 20 and receiving audio signals from the electronic device 20. In the embodiment, the communication unit 17 communicates with the electronic device 20 in a wireless manner.
The playing unit 19 is used for playing the audio signals received from the electronic device 20.
The electronic device 20 receives the direction signal and the control signals from the earphone 10 and executes corresponding operations based on the receiving direction signals and control signals. In the embodiment, when receivingthe first direction signal and the first control signal, the electronic device 20 establishes a phone call. When received the first direction signal and the second control signal, the electronic device 20 disconnects the phone call. When receiving the second direction signal and the first control signal, the electronic device 20 plays music. When receiving the second direction signal and the first control signal, the electronic device 20 pauses the process of playing music.

In step S301, the sensing unit 12 detects rotation of the earphone 10 and respectively generates a direction signal and obtains a rotating angle.
In step S302, the determining unit 13 determines whether the rotating angle is at least a predetermined angle. If the rotating angle is less than the predetermined angle, the procedure returns to step S301; if the rotating angle is at least the predetermined angle, the sensing unit 12 generates a rotating signal and the procedure goes to step S303. In the embodiment, the predetermined angle can be set by the user.
In step S303, the determining unit 13 generates a rotating signal.
In step S304, the calculating unit 14 calculates the number of the generated rotating signals during a predetermined time. In the embodiment, the predetermined time can be set by the user.
In step S305, the comparing unit 15 compares the number with a predetermined value and generates a control signal based on the compared result. In the embodiment, if the number of the generated rotating signals is less than the predetermined value, the procedure goes to step S306; if the number of the generated rotating signals is at least the predetermined value, the procedure goes to step S307.
In step S306, the comparing unit 15 generates a first control signal and the procedure goes to step S308.
In step S307, the comparing unit 15 generates a second control signal and the procedure goes to step S308.
In step S308, the communication unit 17 transmits the direction signals and the control signals to the electronic device 10.
In step S309, the electronic device 10 executes corresponding operation based on the received direction signal and the control signal. In the embodiment, when receiving the first direction signal and the first control signal, the electronic device 20 establishes a phone call. When receiving the first direction signal and the second control signal, the electronic device 20 disconnects the phone call. When receiving the second direction signal and the first control signal, the electronic device 20 plays music. When receiving the second direction signal and the first control signal, the electronic device 20 pauses the process of playing music.
As described, the earphone 10 can control the electronic device 20 to execute operations by moving the earphone 10 without pressing the buttons on the earphone.
