Description of the invention (1) Field of the invention: The present invention relates to a telephone system, especially a hands-free answering system for mobile phones that does not require voice recognition. Background of the Invention: A problem related to the attendance telephone system is the problem that the operator will be distracted when answering a call while the driver is driving. In particular, to answer a call, the car operator must pick up the telephone receiver or keys. In any form, the operator ’s attention, especially their hands and sight must be turned back to the conversation. As a result, the car operator will not be able to concentrate completely for a short period of time ^). Even a brief distraction is enough to cause an accident to the operator. Therefore, when a car operator answers—incoming calls, the chance of an accident increases. A similar problem occurs when the user must enter numbers on the telephone keypad to generate a call. For the aforementioned problems, the current solution is to use a hands-free telephone system with a voice control system that responds to human voice. At present, several mobile phone manufacturers use the system ^. These systems are not simple-expensive-and-communicable ... honey. Furthermore, using voice recognition systems to answer calls involves many obstacles. In the surrounding environment where a considerable amount of noises such as cars often occur, the reliable voice control of JSJI is held by the cone. In addition, the position of the microphone is usually some distance away from the user's mouth, such as on the sun visor overhead. As a result, it is necessary to be able to listen to the man ’s name required by the operator.

Description of the invention (4) After waiting for the call to not be answered, hang up the call by itself. If, during the "off" period of the alarm tone, the call receiver emits an alcove tone, then the caller and the answerer will be connected, and the caller may be answered. The microphone 20 is connected to the audio detector 25. The audio detector 25 includes a bandpass filter 30 and a comparison circuit 40. The band-pass filter 30 filters the audio input signal received by the microphone 20 in the " off " period to a specific bandwidth Fa Hz. In a preferred embodiment, the activation frequency range is equivalent to limiting the frequency at which the audio input can only match the vocals. This range can be a fixed range or a programmable dynamic range. If it is dynamic, the user can adjust this range during system operation. The effect of background dimension can be minimized with a smaller bandwidth, but the response of the call recipient must be more accurate. The band-pass lubricator 30 transmits the post-lubo signal to a comparison circuit 40 of a supervised audio input signal. The comparison circuit 40 compares the filtered audio input signal with the rise-time critical value TR seconds and a quasi-peak ( level — peak) Comparison of critical value TL volts. The critical limit value TL corresponds to a relative value corresponding to a reference level based on the magnitude of the surrounding or background noise inherent in the surrounding environment. The reference level can be detected by determining the amount of surrounding noise by sampling the microphone 20 before the initial ringing stage of the alarm tone. When the comparison circuit 40 detects whether the call recipient is responding to the call, the detected level is compared with the reference level. The difference between these two levels will be compared to determine whether the critical value has been exceeded. The critical value limit may be fixed or may be programmed by the recipient of the call, for example, by inputting a different critical value via the keyboard 80. Similarly, the rise time TR can also be fixed or dynamic. The length of the rise time is set to-.--------1T line. X (Clear t: '»1. ·· '!

Description of the invention (5) The detected energy is equivalent to human voice, so it can eliminate the detection of rumbling sound, slamming sound and other noises. When both TR and 1 have been exceeded, the sudden rise in the audio signal and the simultaneous intensity change will be detected separately. This indicates that the call recipient is trying to answer the call. Once this event occurs, the comparison circuit 40 generates a trigger signal, and transmits the signal to the control processor 50, the processor then causes the call to be answered, also, between the caller and the call learner Line two-way communication. FIG. 2 is an example of a flowchart of the system operation as described above. At the same time, if the call recipient chooses, the call can also be answered using the traditional keyboard method. The call recipient presses a key or keys on the keyboard 80, and the signal is transmitted to the control processor 50 to enable the call Can be answered. When the call is answered, the incoming audio (sound) signal is received by the wireless receiver 10 and output by the microphone 70. The output audio (voice) signals are input into the microphone 20 and thus delivered to the wireless transmitter 90, and then these signals are sent to the caller via the antenna 5.
