Embodiment
Below in conjunction with the drawings and specific embodiments, technology contents of the present invention is further described.
Under normal circumstances, when user uses dispatch terminal, can pick up the below that dispatch terminal is positioned over user's face, namely substantially keep level with the oral area of user, now the voice messaging of user can more clearly be transferred in the dispatch terminal of the other user.When user is used to complete, somewhere can be hung on conveniently, facilitate take next time.But partner is due to can not simultaneously on-hook, or when multiple user uses dispatch terminal, only have certain customers' on-hook, other users keep using, and now the on-hook sound of on-hook user can form more ear-piercing noise in the user just using terminal simultaneously.The lighter affects the service quality of user, and severe one user can not use.
In order to solve the problem, the invention provides a kind of denoising method, as shown in Figure 1, comprise the following steps:
Receive the positional information of handle, described positional information is from proximity transducer;
Process positional information, for determining the distance of handle and main frame;
If handle and main frame distance are less than set point, then delete the speech data of buffer memory, stop sending speech data;
If handle and main frame distance are greater than set point, Resurvey voice data concurrency send, and recovers normal talking.
First, introduce the positional information receiving handle, described positional information is from the step of proximity transducer.
After user's communication completes, place terminal, now the distance of terminal and main frame can progressively reduce.For better measuring this distance, the present invention is provided with two proximity transducers at the main frame of dispatch terminal, is fixed on the two ends of handle on-hook, and namely one end of microphone one end and receiver arranges one respectively.
In one embodiment of the invention, this proximity transducer is infrared proximity transducer.Like this, any one end of handle is close or when leaving main frame, proximity transducer can detect, and the positional information detected is transferred to host-processor in time.When handle off-hook or on-hook, can impact noise be produced, voice collecting circuit and buffer circuit are set in the host-processor of dispatch terminal, gather speech data from handle microphone and carry out buffer memory.This impact noise is carried out buffer memory in the form of speech, is ready for sending to other users.
Secondly, process positional information is introduced, for determining the step of the distance of handle and main frame.
Host-processor receives the laggard row relax of positional information that proximity transducer sends, and determines the distance between handle and main frame, and utilizes this distance to contrast with set point, thus determine that mobile phone is close to main frame or leaves main frame, obtain comparative result.
Again, if introduction handle and main frame distance are less than set point, then delete the speech data of buffer memory, stop the step sending speech data.
After host-processor obtains comparative result, if now handle is close to main frame, then host-processor deletes the speech data existed in buffer circuit, and stops sending speech data to the other side.That is, impact noise during user's on-hook is not sent to the other side.Can ensure like this, also normally use the user carrying out conversing, can not Consumer's Experience be reduced.
Finally, if introduction handle and main frame distance are greater than set point, Resurvey voice data concurrency send, and recovers the step of normal talking.
If handle is for leaving main frame, then, when the distance that mobile phone leaves main frame is greater than set point, user's off-hook being described, sending enabling signal to voice collecting circuit and buffer circuit.In the process picked, do not send speech data, filter out by this impact noise, prevent from affecting other users.After the process of picking terminates, recover normal talking, host-processor restarts buffer circuit, and voice collecting circuit gathers the speech data in handle microphone, is sent to the other side.By delay process, the present invention can filter out less impact noise, thus reduces the impact on user's communication.
For embodying the technical characterstic of the denoising method based on proximity transducer provided by the invention further, present invention also offers a kind of host-processor, as shown in Figure 2, comprising:
Receiving position information unit, for receiving the location information data from proximity transducer;
Process positional information unit, for determining the distance of handle and main frame;
Location comparison unit, for determining that handle still leaves main frame close to main frame
Control unit, according to comparative result to voice collecting circuit and buffer circuit sending controling instruction.
For embodying the technical characterstic of a kind of denoising method provided by the invention further, present invention also offers a kind of dispatch terminal, as shown in Figure 3, comprise voice collecting circuit, buffer circuit, handle and microphone, voice collecting circuit, buffer circuit and microphone are arranged on the inside of handle, microphone converts user voice or impact noise to electric signal transmission to voice collecting circuit, buffer circuit is transferred to again after the process of voice collecting circuit, also comprise proximity transducer, host-processor, wherein
Proximity transducer is arranged on above main frame, and its output is connected to host-processor; Host-processor receives the positional information of the handle gathered from proximity transducer, and location information processes, and obtains the distance now between handle and main frame, and the set point of taking out this distance compares.If the distance of handle is less than set point, then host-processor controls buffer circuit, deletes the speech data of institute's buffer memory, and stops sending speech data to the other side.
If the distance of handle and main frame is greater than set point, then restart buffer circuit, buffer memory is carried out to the speech data that voice collecting circuit gathers, and is sent to the other user.
For recording the position of handle better, in one embodiment of the invention, proximity transducer preferably adopts two infrared proximity transducers, is arranged at the two ends of handle hook position respectively.
During due to employing infrared proximity transducer, the light of surrounding environment also can cause interference to infrared proximity transducer.For this reason, the present invention carries out frequency modulation(FM) to the infrared emission light of infrared proximity transducer.Meanwhile, the present invention is provided with filter unit in host-processor, for carrying out bandpass filtering to the positional information of received handle, further filtering interference signals.
When blocking proximity transducer by foreign matter, proximity transducer can prepare on-hook with user and process, and affects the normal talking of dispatch terminal.For this reason, the present invention is also provided with indicator light on the main frame of dispatch terminal, and prompting user has abnormal conditions, call user's attention.Or display reminding information above the display screen having a dispatch terminal, prompting user.
The present invention is by arranging proximity transducer, the positional information of collection scheduling terminal handle, by the distance between main frame, impact noise is processed, finally eliminate the interference of impact noise to meeting, other user speech, improve the Consumer's Experience in meeting.
Above the denoising method based on proximity transducer provided by the present invention, host-processor and dispatch terminal are described in detail.For one of ordinary skill in the art, to any apparent change that it does under the prerequisite not deviating from connotation of the present invention, all by formation to infringement of patent right of the present invention, corresponding legal liabilities will be born.
