FIG. 1 is a schematic diagram of an electronic system 100 of an embodiment of the present invention. As shown in FIG. 1, the electronic system 100 includes a headset device 102 and a computer device 104. In some embodiments, the headset device 102 includes a communication processor 110, an antenna 112, an antenna 114, and a connection node 120. The headset device 102 generally includes a left earphone and a right earphone. The headset device 102 in FIG. 1 refers to one of the left earphone and the right earphone. The communication processor 110 is electrically connected to the antenna 112 and the antenna 114. In some embodiments, the antenna 112 is used to receive a first radio frequency signal that complies with a first wireless communication standard. For example, the first wireless communication standard is wireless local area network (Wi-Fi), but the present invention is not limited thereto. The frequency band used by the wireless local area network (Wi-Fi) may be, for example, 2.4 GHz, 5 GHz, and 6 GHz. The antenna 114 is used to receive a second radio frequency signal that complies with a second wireless communication standard. For example, the second wireless communication standard is Bluetooth, but the present invention is not limited thereto. The frequency band used by Bluetooth may be, for example, 2.4 GHz.

In some embodiments, the headphone device 102 may be, for example, a true wireless headset (True Wireless Stereo: TWS) or a Bluetooth headset, but the present invention is not limited thereto. In some embodiments, the computer device 104 may be, for example, a laptop, a tablet, or a smart phone, but the present invention is not limited thereto. In some embodiments, the headphone device 102 includes a microcontroller (not shown). The microcontroller is used to detect whether the headphone device 102 has been worn in the ear canal of the user. The headphone device 102 further includes a charging module (not shown) for electrically connecting to a lithium battery (not shown). The microcontroller can further receive a battery status signal from the charging module to obtain the capacity status and the charge and discharge status of the lithium battery.

The communication processor 110 converts the first radio frequency signal from the antenna 112 into a first baseband signal, and converts the second radio frequency signal from the antenna 114 into a second baseband signal. The first baseband signal and the second baseband signal are provided to other components (such as a microcontroller) for subsequent processing. In other words, the communication processor 110 is a chip that supports both wireless local area network (Wi-Fi) and Bluetooth, but the present invention is not limited to this. In some embodiments, the connection node 120 is electrically connected to the communication processor 110. The connection node 120 can be, for example, a female end of a connector, but the present invention is not limited to this.

In some embodiments, the communication processor 110 includes an RF module (not shown) and a baseband module (not shown). The RF module is responsible for receiving or sending high-frequency communication signals. The RF module can perform frequency synthesis, data conversion, and noise filtering. The RF module may include a power amplifier (PA), a low-noise amplifier (LNA), a frequency multiplexer (diplexer), a transceiver switch (TR switch), a surface acoustic wave filter (SAW filter), a low-pass filter (LPF), an isolator (isolator), a coupler (coupler), and a balun (balun), but the present invention is not limited thereto.

The baseband module is responsible for data processing and storage. For example, the baseband module can perform message encoding, encryption and decryption encoding, frequency hopping, and packet processing. The baseband module may include a digital signal processor (DSP), a microcontroller (MCU), an analog-to-digital converter (ADC), a digital-to-analog converter (DAC), a flash memory, and a static random access memory (SRAM), but the present invention is not limited thereto.

In some embodiments, the computer device 104 includes a built-in antenna 116, a communication processor 118, a connection node 122, and a switch element 126. The communication processor 118 is electrically connected to the built-in antenna 116 and the switch element 126. In some embodiments, the communication processor 118 is a chip that supports wireless local area network (Wi-Fi), but the present invention is not limited thereto. When the connection node 122 of the computer device 104 is electrically connected to the connection node 120 of the headphone device 102, the computer device 104 receives the first radio frequency signal through the antenna 112 of the headphone device 102. In some embodiments, the connection node 122 can be, for example, a male end of a connector, but the present invention is not limited thereto.

Therefore, through the electrical connection between the connection node 120 and the connection node 122, the headset device 102 can be set on the computer device 104. In some embodiments, when the connection node 122 of the computer device 104 is electrically connected to the connection node 120 of the headset device 102, the computer device 104 can simultaneously receive the first RF signal through the antenna 112 and the built-in antenna 116 of the headset device 102.

The built-in antenna 116 is used to receive a first radio frequency signal that complies with a first wireless communication standard (e.g., Wi-Fi). In other words, the built-in antenna 116 of the computer device 104 and the antenna 112 of the headset device 102 are both used to receive a first radio frequency signal that complies with a first wireless communication standard (e.g., Wi-Fi). Therefore, when the connection node 122 of the computer device 104 is electrically connected to the connection node 120 of the headset device 102, the computer device 104 can receive the first radio frequency signal through the antenna 112 of the headset device 102, so as to improve the wireless communication efficiency of the computing device 104.

In some embodiments, when the connection node 122 of the computer device 104 is not electrically connected to the connection node 120 of the headset device 102, the computer device 104 receives the first RF signal through the built-in antenna 116. In some embodiments, when the connection node 122 of the computer device 104 is electrically connected to the connection node 120 of the headset device 102, the switch element 126 is turned on. In the embodiment of FIG. 1, when the switch element 126 is turned on, the communication processor 118 receives the first RF signal from the antenna 112 of the headset device 102 through an antenna transmission path 124. That is, when the connection node 122 of the computer device 104 is electrically connected to the connection node 120 of the headphone device 102, the switch element 126 is turned on, so that the communication processor 118 receives the first RF signal through the antenna 112 of the headphone device 102.

On the contrary, when the connection node 122 of the computer device 104 is not electrically connected to the connection node 120 of the headphone device 102, the switch element 126 is not conducting. That is, when the connection node 122 of the computer device 104 is not electrically connected to the connection node 120 of the headphone device 102, the communication processor 118 can only receive the first RF signal through the built-in antenna 116. In some embodiments, the communication processor 118 converts the first RF signal into a baseband signal. The baseband signal is provided to other components for subsequent processing.

FIG. 2 is a schematic diagram of a computer device 104 of the electronic system 100 of FIG. 1 according to an embodiment of the present invention. As shown in FIG. 2, the computer device 104 includes a keyboard portion 200, a hinge portion 202, and a display portion 204. In some embodiments, the display portion 204 is electrically connected to the keyboard portion 200 via the hinge portion 202. When the computer device 104 is in operation (for example, a user is using the computer device 104), there is an angle between the keyboard portion 200 and the display portion 204. In some embodiments, the angle between the keyboard portion 200 and the display portion 204 may be a sharp angle, a right angle, or a blunt angle according to the user's usage habits. The connection node 122 of the computer device 104 is disposed on the top of the display unit 204 when the computer device 104 is operating.

For example, the connection node 122 of the computer device 104 is disposed at position A and/or position B of the display unit 204 when the computer device 104 is in operation. Since the headphone device 102 includes a left earphone and a right earphone, the left earphone can be disposed at position B of the display unit 204, and the right earphone can be disposed at position A of the display unit 204, so that part of the antenna structure of the headphone device 102 (for example, the antenna 112) becomes an external antenna of the computer device 104, so as to enhance the wireless communication performance of the computer device 104.
