Detailed Description
In order to make the technical content of the present invention comprehensible, preferred embodiments are described below.
Referring to fig. 1, an architecture of an audio transmission system according to the present invention is shown.
The audio transmission system 1 of the present invention may be in the form of a hearing aid or an earphone with a microphone, for example, a bluetooth earphone, but the present invention is not limited thereto. The audio transmission system 1 is used to establish a connection with the electronic device 2, and can have a call using mode, a music using mode, and an ambient sound using mode, but the invention is not limited to the audio transmission system 1 only being able to execute the above modes. In the embodiment of the invention, the electronic device 2 may be a smart phone, a tablet computer, a notebook computer, or the like. The audio transmission system 1 includes a wireless communication module 10, a sound receiving module 20, a signal processing module 30, a memory module 40, a sound adjusting module 50, an output module 60, and a selection module 70.
The wireless communication module 10 has a function of transmitting wireless signals, and can utilize communication protocols such as bluetooth, near field communication or WIFI to receive wireless signals from the electronic device 2. In an embodiment of the invention, the wireless communication module 10 may receive a wireless communication signal or a wireless audio signal from the electronic device 2, the wireless communication signal may be a call signal with a bidirectional communication function, and the wireless audio signal may be a voice signal received in a unidirectional manner, but the invention is not limited thereto. The wireless communication signal may be used to perform a talk use mode and the wireless audio signal may be used to perform a music use mode. The sound receiving module 20 may be a microphone for receiving an ambient sound signal, and the ambient sound signal may be used for executing the ambient sound usage mode.
The signal processing module 30 is electrically connected to the wireless communication module 10 and the sound receiving module 20, and is configured to determine whether the wireless communication module 10 and the sound receiving module 20 receive an external signal, that is, whether the wireless communication signal, the wireless audio signal or the environmental sound signal is transmitted to the audio transmission system 1. The memory module 40 is used for storing a plurality of parameters to match different wireless signals and environmental sound signals. Therefore, in an embodiment of the present invention, the memory module 40 stores the first parameter, the second parameter and the third parameter in cooperation with the wireless communication signal, the wireless audio signal or the environmental sound signal.
The sound adjusting module 50 is electrically connected to the wireless communication module 10, the sound receiving module 20, the signal processing module 30 and the memory module 40. The sound adjusting module 50 directly adjusts the received wireless communication signal, the received wireless audio signal or the received environmental sound signal according to the first parameter, the second parameter or the third parameter, respectively, to generate an adjusted sound signal. In an embodiment of the present invention, the sound adjusting module 50 is an equalizer, and the first parameter, the second parameter or the third parameter are gain values to be adjusted. Therefore, the first parameter can represent the gain value of the wireless communication signal to be adjusted, so that the user can obtain better communication quality. The second parameter can represent the gain value of the wireless audio signal to be adjusted, so that the wireless audio signal can generate different situation effects. The third parameter represents the gain value of the environmental sound signal, so as to match with the audiogram of the user to gain and adjust the frequency of the adjustment sound. Since the technology for creating the audiogram is well known to those skilled in the art and is not the focus of the improvement, it is not described herein. In this way, the sound adjusting module 50 can adjust a gain value of the received wireless communication signal, the received wireless audio signal or the received ambient sound signal according to the first parameter, the second parameter or the third parameter pre-stored in the memory module 40, so as to generate an adjusted sound signal.
Finally, the audio transmission system 1 may also have an output module 60. The output module 60 is a speaker electrically connected to the sound adjusting module 50 for outputting the adjusted sound signal to the user.
Therefore, in an embodiment of the present invention, when receiving the wireless communication signal, the signal processing module 30 executes a call using mode to enable a user to perform a call. When receiving the wireless audio signal, the signal processing module 30 executes a music using mode to allow the user to listen to music. Finally, when receiving the ambient sound signal, the signal processing module 30 executes the ambient sound usage mode to let the user hear the external sound. In one embodiment of the present invention, the call usage mode is the first processing order of the signal processing module 30, the music usage mode is the second processing order of the signal processing module 30, and the ambient sound usage mode is the third processing order of the signal processing module 30. In other words, when the wireless signal and the ambient sound signal are received simultaneously, the sound adjusting module 50 adjusts for the wireless signal. When receiving the wireless communication signal and the wireless audio signal at the same time, the sound adjusting module 50 takes the wireless communication signal as a priority. Therefore, the audio transmission system 1 preferentially allows the user to use the conversation use mode, and when there is no wireless communication signal, it will determine whether to execute the music use mode and the ambient sound use mode in sequence.
However, the audio transmission system 1 may also have a selection module 70 for providing a user to select a mode, such that the audio transmission system 1 only executes the call using mode, the music using mode or the ambient sound using mode. In other words, when the user selects to switch to the call mode, the audio transmission system 1 can only receive and process the wireless communication signal, and the first parameter is used for adjustment. When the user selects to switch to the music using mode, the audio transmission system 1 can only receive and process the wireless audio signal, and the second parameter is used for adjustment. When the user selects to switch to the environment using mode, the audio transmission system 1 can only receive and process the environment audio signal, and the environment audio signal is used for adjustment. The selection module 70 may also allow the user to select an automatic mode, that is, the signal processing module 30 is used to directly determine whether the audio transmission system 1 receives the wireless communication signal, the wireless audio signal or the environmental sound signal, and then automatically perform the subsequent parameter adjustment process.
It should be noted that, the modules of the audio transmission system 1 may be configured by a hardware device, a software program combined with the hardware device, a firmware combined with the hardware device, and the like, but the invention is not limited to the above-mentioned manner. In addition, the present embodiment only illustrates the preferred embodiments of the present invention, and all possible combinations and modifications are not described in detail to avoid redundancy. However, one of ordinary skill in the art should appreciate that each of the above modules or elements is not necessarily required. And may include other existing modules or components in greater detail for practicing the invention. Each module or component may be omitted or modified as desired, and no other module or component may necessarily exist between any two modules.
Please refer to fig. 2, which is a flowchart illustrating a method of audio processing according to the present invention. It should be noted that, although the audio transmission system 1 is taken as an example to describe the audio processing method of the present invention, the audio processing method of the present invention is not limited to the audio transmission system 1 with the same structure.
First, before processing the audio, step S0 is performed: either manual or automatic mode is selected.
If the automatic mode is selected, the process proceeds to step S1: whether a wireless communication signal is received is judged.
First, the signal processing module 30 determines whether the wireless communication module 10 receives an external signal. The signals receivable by the wireless communication module 10 include wireless communication signals and wireless audio signals.
Therefore, if the wireless communication module 10 receives the wireless communication signal, the step S2 is performed: the wireless communication signal is adjusted according to a first parameter.
The sound adjusting module 50 reads the first parameter from the memory module 40 to adjust the received wireless communication signal.
If the wireless communication module 10 does not receive the wireless communication signal, the signal processing module 30 further performs step S3: and judging whether the wireless audio signal is received or not.
At this time, the signal processing module 30 can further determine whether the wireless communication module 10 receives the wireless audio signal.
If the wireless audio signal is received, step S4 is executed: the wireless audio signal is adjusted according to a second parameter.
The sound adjusting module 50 reads the second parameter from the memory module 40 to adjust the received wireless audio signal.
If the wireless communication module 10 does not receive the wireless communication signal and the wireless audio signal, the signal processing module 30 further executes step S5: whether an ambient sound signal is received is judged.
After confirming that no wireless signal is received by the wireless communication module 10, the signal processing module 30 may further determine whether the sound receiving module 20 receives the ambient sound signal.
If the ambient sound signal is received, step S6 is executed: adjusting the ambient sound signal according to a third parameter.
The sound adjusting module 50 reads the third parameter from the memory module 40 to adjust the received ambient sound signal.
After the steps S2, S4, and S6, the sound adjusting module 50 performs the step S7: generating an adjusting sound signal to output the adjusting sound signal.
After performing the adjusting steps of step S2, step S4, and step S6, the sound adjusting module 50 adjusts the received wireless communication signal, the received wireless audio signal, or the received ambient sound signal to generate an adjusted sound signal. Finally, the output module 60 outputs the adjusted audio signal to the user.
It should be noted that the audio processing method of the present invention is not limited to the above-mentioned sequence of steps, and the sequence of steps can be changed as long as the objective of the present invention is achieved.
Therefore, the user can adjust the audio transmission system 1 in different use situations in a manual or automatic manner to obtain the best hearing effect.
It should be noted that the above embodiments only illustrate the preferred embodiments of the present invention, and all possible combinations of the variations are not described in detail for avoiding redundancy. However, one of ordinary skill in the art should appreciate that each of the above modules or elements is not necessarily required. And may include other existing modules or components in greater detail for practicing the invention. Each module or component may be omitted or modified as desired, and no other module or component may necessarily exist between any two modules. The scope of the claims should be determined only by the appended claims, and not by the broadest interpretation of the following claims.
