Description

  The present invention relates to a peripheral device of a mobile phone, and more particularly to a mobile phone case that operates and controls illumination in response to an incoming call of the mobile phone.

  The “mobile phone” as used in the present invention includes all devices similar to mobile radio terminals such as a mobile phone, a PHS, a smartphone, and various portable radio devices.

  In cell phone cases, in addition to functions to protect cell phones, there is a growing need for decorativeness. Not only are there a variety of materials, designs and colors, but light emitting materials are used on the cell phone cases. Products also exist.

  All of such existing mobile phone cases employ a method of operating an illumination lamp via a sensor that wirelessly detects a radio wave when an incoming call is received by the mobile phone. Therefore, due to the progress of 3G networks and signal failures existing in 3G mobile phones, in current mobile phone cases, illumination often does not light up and malfunctions occur. In addition, such wireless sensor cases and accessories require an independent power supply system, so that power is supplied by a button battery. However, since the button battery has a small capacity, its service life is short, and since it cannot be recharged and cannot be used repeatedly, disposal of the button battery may affect the environment.

  Based on the above, the present invention is a mobile phone voice interlocking illumination case designed to solve the problem that the existing wireless sensor type mobile phone case is not suitable for 3G mobile phone and the need for an independent power supply system. It is.

  In order to solve the technical problem posed by the present invention, at least a case used in a mobile phone having an interface capable of outputting a power supply and an audio signal required for the operation of an LED lamp is provided with a case main body. At least one LED lamp and a control circuit for controlling blinking of the LED lamp are provided, and a connector connected to the control circuit is provided inside the case body, and the power supply and sound required for the operation of the LED lamp are provided. It is used as a plug connector for acquiring a signal from the interface of the mobile phone.

  In a solution obtained by further improving the present invention, the control circuit includes an LED driver control chip and an amplifier circuit, and the LED driver control chip is connected to the LED lamp to control on / off of the LED lamp power. After the amplifier circuit is serially connected to the capacitor, the amplifier circuit is connected between the mobile phone audio signal input terminal of the plug connector and the control signal input terminal of the LED driver control chip.

  Moreover, the area | region corresponding to the LED lamp of the said case main body was made into the transparent logo area | region.

  Furthermore, the LED lamp includes red, green and blue LED lamps.

  According to the present invention, a plug connector connected to the interface of the mobile phone is adopted, and the battery of the mobile phone is shared as a continuous power supply for the LED lamp, so that the LED lamp blinks by the audio signal output from the mobile phone. With precise control, we were able to truly realize the effect of stable incoming illumination. In addition, by solving the deficiency of requiring the existence of an independent power supply system, it was possible to reduce costs and reduce environmental impact.

It is a figure which shows the back surface structure in an example of Embodiment of the mobile telephone audio | voice interlocking | linkage type illumination case of this invention. It is a figure which shows the decomposition | disassembly structure in an example of embodiment of the mobile telephone audio | voice interlocking | linkage type illumination case of this invention. It is a figure which shows the circuit structure in an example of embodiment of the mobile telephone audio | voice interlocking | linkage type illumination case of this invention.

  Hereinafter, the configuration of the present invention will be described more specifically by combining the drawings and the preferred embodiments of the present invention.

  1 and 2 show a case main body 1 and three or more LED lamps 2 incorporated in the case main body 1 according to the present invention. In a specific implementation process, it is desirable to have at least red, green and blue LED lamps. In order to achieve the dynamic effect of alerting each LED lamp by alternately flashing, a case control circuit is provided in the case body 1 and the printed circuit board 3 of the control circuit is mounted in the bottom of the case body 1. . A single plug connector 4 is provided in the bottom of the case body 1 in order to cause the LED lamp 2 to acquire a lighting control power source and to cause the control circuit to control an open start signal.

  In use, the plug connector 4 is inserted into the data interface of the mobile phone 7, the power supply for operating the LED lamp 2 and the audio signal are acquired via the data interface of the mobile phone 7, and according to the audio signal of the mobile phone The lighting and blinking of the LED lamp 2 are controlled by the activation of the control circuit. In order to enhance the appreciation of the present invention and to solve the monotonousness of the case body 1, the area corresponding to the LED lamp 2 of the case body 1 is set to the transparent logo area 1a or an independent LED in the transparent logo area 1a. Provide a lamp.

  In order to facilitate the attachment of the cellular phone to the present invention, one bottom cover 5 is provided on the bottom of the case body 1. The bottom cover 5 is coupled to the case body 1 via screws 6.

  FIG. 3 shows a control circuit including an LED driver control chip U1 and an amplifier circuit composed of a transistor Q1. The LED driver control chip U1 is connected to the LED lamps LED1, LED2, and LED3 to control on / off of the power supply of the LED lamps LED1, LED2, and LED3.

  The operating power of the LED driver control chip U1 is obtained from the data interface of the mobile phone 7 via the power terminal Vcc and the ground terminal GND. The voltage input terminal of the amplifier circuit is connected to the mobile phone audio signal input terminal IN of the plug connector 4 via the capacitor C2. The voltage output terminal of the amplifier circuit is connected to the control signal input terminal SW of the LED driver control chip U1. When the mobile phone receives an incoming call or music sounds, the audio signal of the mobile phone is input via the mobile phone audio signal input terminal IN of the plug connector 4. After that, through the coupling of the capacitor C2, the control signal is generated by configuring the operation of the amplifier circuit in the transistor Q1, and the LED driver control chip U1 is operated via the control signal input terminal SW of the LED driver control chip U1. The LED lamps LED1, LED2, and LED3 are blinked.
