An electric composite detection antenna is disclosed. The antenna includes two RF antenna disposed on two sides of the circuit system of the electronic device, and a RF compensation system is disposed in the circuit system and includes an inductive sensing coil, and the induction coil can detect signal attenuation of any RF antenna subjected to external interference, so as to generate a detection signal. The RF compensation system can notice the control unit, to quickly drive any antenna matching circuit to switch to the RF antenna which is not interfered, or to quickly adjust antenna power or adjust the matching value of the RF antenna between the external environment, so that the preset electronic device can perform the stable transmission RF signal through the RF antenna without external interference, and maintain better power for RF signal transmissions.

A Bluetooth headset combined with antenna and touch sensor, which integrates a sensing touch member inside a button of the Bluetooth headset with a Bluetooth antenna. The antenna element with touch function increases the density of the earphone component, in addition to the waterproof improvement, and the Bluetooth antenna is set near the external position of the Bluetooth headset, which makes the audio signal transmission effect clearer. Further, a first touch matching circuit, a second touch matching circuit and a changeover switch are electrically connected between the antenna element and the touch sensing module. When the signal of the antenna element is blocked, the changeover switch automatically switches between the first touch matching circuit and the second touch matching circuit to perform frequency adjustment and selects the better signal of the first or second touch matching circuit to do a circuit matching.

The present disclosure illustrates a stylus with magnetic induction wheel. In the stylus, a pen holder includes a stylus head and a pen cap, and the pen holder is defined with a hollow accommodation space having a hole. A wheel is assembled inside the accommodation space and aligned with the hole, and a central axis is protruded on and extended from two opposite sides of the wheel to abut with the stylus head and the pen cap. A magnetic component is disposed on the central axis, and a magnetic induction device is disposed in the accommodation space to sense a variation of angular momentum or angular velocity of the magnetic field lines of the S and N magnetic poles of the magnetic component. As a result, the user can use the stylus to control an electronic device more easily.

A support unit comprising a cover, a positioning unit and a bracket is provided. The cover is pivotably connected to a housing of the portable electronic device and can be received in the housing. The positioning unit is fixed to the housing and includes a plurality of limiting recesses. The bracket includes a first end and a second end that opposite. The first end is connected to the positioning unit, and the second end is pivotably connected to the cover. When the cover is expanded out of the housing, the first end of the bracket is driven by the cover to move relative to the positioning unit, and then the first end of the bracket is engaged with a limiting recess of the positioning unit to fix the expansion angle of the cover relative to the housing. A portable electronic device including the support unit is also provided.
