Handheld equipment capable of switching signal receiving modes

Abstract

The invention relates to handheld equipment capable of switching signal receiving modes, comprising a telescopic antenna, a telecommunication receiving and sending module, a satellite signal module and a switching circuit, wherein the telescopic antenna can extend to a first length and withdraw to a second length; the telecommunication receiving and sending module receives and sends a first frequency signal when the telescopic antenna extends to the first length and receives and sends a second frequency signal when the telescopic antenna extends to a second length; the satellite signal module receives a satellite signal when the telescopic antenna extends to the second length; the switching circuit receives the switching signal; the switching circuit is electrically connected with the telescopic antenna; when the telecommunication receiving and sending module is electrically connected with the telescopic antenna, the telescopic antenna is adjusted to the first length to receive and send the first frequency signal and adjusted to the second length to receive and send the second frequency signal, or when the switching signal is obtained, the telescopic antenna is electrically connected with the satellite signal module, and the telescopic antenna is adjusted to the second length so that the satellite signal module receives the satellite signal. The handheld equipment can receive various frequency signals by one antenna so that different function modules receive and send different frequency signals to increase the practicability.

Description

technical field [0001] The present invention relates to a hand-held device, in particular to a telescopic antenna designed to receive signals of various frequencies, which can be used to send and receive signals of different frequencies for a telecommunication transceiver module. The telescopic antenna can be adjusted to match the frequency of telecommunication signals used by the local telecommunication system. And it is a hand-held device with switchable signal receiving mode that can cooperate with local telecommunication numbers for communication work. Background technique [0002] With the progress of the times and social competition, it is common to travel for work. In addition, modern people pay attention to the quality of life, and they often carry mobile phones when traveling on holidays. However, the number of the mobile phone is generally only applicable to one frequency, and in order to cooperate with users of multiple numbers, the existing mobile phone has a du...

Problems solved by technology

[0006] Second, although some mobile phones are equipped with Global Positioning System (GPS), they need to be additionally equipped with special antennas for sending and receiving satellite signals, so they occupy part of the space inside the mobile phone.

[0007] Third, mobile phone users may be satellite TV users, but mobile phones generally use telecommunication networks to transmit TV images, and telecommunication networks cannot be combined with satellite systems. The reason is that the frequency of transmission signals is different, so it needs to be configured to receive Antennas for satellite signals, and industry manufacturers will not configure satellite TV due to factors such as cost and phone volume, which limits the functionality of mobile phones

[0008] This shows that above-mentioned existing hand-held device obviously still has inconvenience and defect in structure and use, and urgently needs to be further improved

In order to solve the above-mentioned problems, the relevant manufacturers have tried their best to find a solution, but for a long time no suitable design has been developed, and the general products do not have a suitable structure to solve the above-mentioned problems. Urgent problem
