Benefits of technology

Inventions have been developed over time but they all suffer from certain limitations such as complexity, lacking flexibility, difficulty detecting triggers within short distances (such as when people don't want their hands free), poor reliability due to variations caused by environmental factors like temperature variation, humidity, etc., limited battery life, high cost, complicated circuits used during operation, and potential safety hazards associated therewith.

Problems solved by technology

The technical problem addressed in this patented text relates to improving wireless communication devices that have multiple functionalities like metal casings or high integration capabilities without compromising their overall functionality. This can lead to reduced signal quality due to poor radio reception caused by interference from external sources such as hands holding them during operation.

Embodiment 1

[0028] In this embodiment, the metal trigger detection device is designed to be used as a metal button, and the metal button is arranged on the front of the mobile terminal and is not grounded. Such as figure 2As shown, the metal keys 101, 102 and 103 form the self-resonant frequency f1 in the untriggered state through their respective resonant matching circuits 111, 112 and 113 respectively, and the frequency of the sending and receiving signals of the signal generating module 22 and the signal receiving module 23 is also For f1, the signal generates a path of frequency f1 at both ends of the transceiver. The signal receiving module 23 connected with the three metal buttons receives the signal of frequency f1 in real time, and is provided with a signal strength receiving threshold value. When the signal receiving module 23 receives a frequency higher than the signal strength receiving threshold value, the frequency is When the signal of f1 is regarded as the metal button is...

Embodiment 2

[0031] In this embodiment, the metal trigger detection device is designed to be used as a metal button, the metal button is arranged on the front of the mobile terminal and is not grounded, and the metal button is provided with a unilateral gap. Such as Figure 4 As shown, the metal buttons 104, 105 and 106 are respectively formed through their respective resonant matching circuits 114, 115 and 116. The self-resonant frequency in the triggered state is f2, and the transceiving frequency of the signal generating module 22 and the signal receiving module 23 is also f2. , the signal generates a path of frequency f2 at the two ends of the transceiver, and at this time, the signal receiving module 23 can receive a signal with a frequency of f2 and above the signal strength receiving threshold value, and generate a judgment result that the metal button is triggered, and the control chip 24 Execute the trigger operation. However, the self-resonant frequency f1 when the metal button ...

Embodiment 3

[0035] In this embodiment, the metal trigger detection device is designed to be used as a metal piece of a hand-held sensing device, and the metal piece is set at a side position that is easily accessible when a person holds the mobile terminal and is not grounded. Such as Figure 5 As shown, the self-resonant frequency of the metal sheet 107 formed by the resonant matching circuit 117 in the untriggered state is f1, the frequency of the sending and receiving signals of the signal generating module 22 and the signal receiving module 23 is also f1, and the signal generates a frequency f1 at both ends of the sending and receiving access. The signal receiving module 23 connected to the metal sheet 107 receives the signal of frequency f1 in real time, and is provided with a signal strength receiving threshold value. When the signal receiving module 23 receives a signal higher than the signal strength receiving threshold value, the frequency is f1 It is considered that the metal s...

Abstract

The invention discloses a metal button device for a mobile terminal, and a mobile terminal with same. The metal button device comprises a metal triggering detecting device, a resonance matching circuit, a signal generating module and a signal receiving module. The resonance matching circuit is used for matching the metal triggering detecting device and realizing bandpass in a preset frequency. The signal generating module is used for generating a source signal with a preset frequency. The signal receiving module is used for receiving a self-resonance frequency of the metal triggering detecting device and generating a judgment result for judging whether the self-resonance frequency is the preset frequency. Human body triggering causes change of the self-resonance frequency which is generated by the metal triggering detecting device. Based on the change, the signal receiving module can judge whether the triggering detecting device is triggered. Compared with a designing mode of closed-loop power detecting based on an inner complicated circuit design in a chip, change of the self-resonance frequency caused by contact between the human body and the metal triggering detecting device is more obvious. Furthermore a simple, universal and reliable handheld mobile terminal state detection design is realized.
