Throughout the drawings, like numerals indicate similar components.

[An example of a device location notification system]

Please refer to FIG. 1 , which is a block diagram of a system for prompting device location according to an exemplary embodiment of the present invention. The device location prompting system 1 provided in this embodiment is suitable for electronic devices, such as small electronic devices that users are accustomed to carry around, such as mobile phones, tablet computers, etc. Such electronic devices are easy to be forgotten by users in the places they pass by due to their small size and lightness. For example, many users have experience in finding electronic devices such as mobile phones or tablet computers that are conveniently placed in areas such as their own rooms or living rooms. The device location prompting system 1 provided by this embodiment will help the user to conveniently find electronic devices such as mobile phones or tablet computers in the aforementioned situations.

That is to say, the device location prompting system 1 provided in this embodiment is used to prompt the location of an electronic device (such as an electronic device such as a mobile phone or a tablet computer) within a region (such as a room, a living room, an office, etc.) Location. As shown in FIG. 1 , the device location prompting system 1 includes a voice input module 10 , a wake-up module 30 , a voice recognition module 40 , a storage module 50 and a ringing module 60 . The wake-up module 30 is connected to the voice input module 10 , the voice recognition module 40 is connected to the wake-up module 30 and the storage module 50 , and the ringing module 60 is connected to the voice recognition module 40 . It should be noted that the device location prompting system 1 is set on the electronic device of the foregoing example, and operates in a first mode and a second mode, wherein the first mode is, for example, a sleep mode, and the second mode is, for example, a working mode .

Further description, when the device position prompting system 1 operates in the first mode, the voice input module 10 will continue to work to receive an audio data. The voice input module 10 includes, for example, a microphone, an analog-to-digital converter, and a temporary memory... and other input devices; at the same time, the wake-up module 30 will determine whether the amplitude of the audio data is greater than or equal to a threshold amplitude. Next, if the wake-up module 30 determines that the amplitude of the audio data is greater than or equal to the threshold amplitude, the wake-up module 30 will send a wake-up signal. Next, the voice recognition module 40 will be awakened by the wake-up signal, so that the device position notification system 1 enters the second mode from the first mode. When the device location prompting system 1 operates in the second mode, an audio data received by the voice input module 10 will be stored in the storage module 50 , and then the voice recognition module 40 will read the audio data from the storage module 50 and store it in the storage module 50 . Determine whether there is a control sentence in the audio data. If the voice recognition module 40 determines that there is a control sentence in the audio data, the voice recognition module 40 will issue a prompt message. Finally, the bell module 60 receives the prompt information, and sends out a prompt signal according to the prompt information, which is used to prompt the user where the electronic device is located within the area.

It should be noted that, when the device position prompting system 1 operates in the first mode, after the voice input module 10 receives an audio data, the wake-up module 30 determines that the amplitude of the audio data is greater than or equal to a threshold amplitude and sends a wake-up signal accordingly. In addition, when the device position prompting system 1 operates under the second mode, an audio data received by the voice input module 10 will be stored in the storage module 50, and then read and judged by the voice recognition module 40 whether in this audio data There is a control statement. That is to say, in the first mode, the wake-up module 30 can be regarded as a back-end module of the voice input module 10 , and in the second mode, the storage module 50 can be regarded as a back-end module of the voice input module 10 .

For example, if an electronic device is provided with the device location prompting system 1 provided in this embodiment, when the user forgets the electronic device somewhere in a region (eg, a room, a living room, an office, etc.) , the user can use the device location prompting system 1 to find the electronic device. In this example, the user must first make a sound, and then the voice input module 10 will receive the sound; at the same time, the wake-up module 30 will determine whether the amplitude of the sound is greater than or equal to a threshold amplitude. That is, the wake-up module 30 will determine whether the volume of the sound is greater than or equal to a threshold value. If the wake-up module 30 determines that the volume of the sound is greater than or equal to the threshold value, the wake-up module 30 will send a wake-up signal. Next, the voice recognition module 40 will be awakened by the wake-up signal, so that the device position notification system 1 enters the second mode from the first mode.

In this embodiment, the aforementioned threshold amplitude is, for example, a trigger level set by a digital signal comparator. When audio data input by the user is received, the digital signal of the audio data is compared with the trigger level. To put it simply, if the volume of the sound made by the user is loud enough, the device position prompting system 1 can enter the second mode from the first mode. The aforementioned control sentences and trigger levels may be preset in the device by the manufacturer of the electronic device when it leaves the factory, or the user may download and install an application program, and then change the settings, which is not limited in the present invention.

In the second mode, the user has to speak a preset control sentence (eg: hello hello!) to make the device position prompting system 1 send out a prompt signal to prompt the user where the electronic device is located within the area . That is to say, the user has to record a control sentence (eg: hello hello!) in advance and store it in the storage module 50 . It should be noted that the initial setting of the control statement can be completed when the system is shipped from the factory. Then, in the process of judging whether the user speaks the preset control sentence, the voice recognition module 40 will determine whether there is a default control sentence in the audio data received by the voice input module 10, that is, in the second In the mode, the audio data spoken by the user is also stored in the storage module 50, and the control sentence and the audio data stored in the storage module 50 can be compared through the processor and the speech recognition algorithm in the speech recognition module 40. If the voice recognition module 40 determines that there is a default control sentence in the audio data, the voice recognition module 40 will send a prompt message to the bell module 60, so that the bell module 60 receives the prompt message and sends out a prompt signal according to the prompt message, It is used to prompt the user where the electronic device is located within the area. In this embodiment, the prompt information can be a bell, a vibration, a flashing light, or a combination thereof. That is, when the voice recognition module 40 determines that there is a default control sentence in the audio data, the bell module 60 will ring, vibrate, flash lights, or simultaneously emit a bell and vibrate, etc. In this way, the user can find the location of the electronic device according to the bell, vibration or light, etc.

As can be seen from the foregoing description, as long as the electronic device provided with the device location prompting system 1 is turned on, the user can find where the electronic device is placed by voice control at any time.

In this embodiment, the speech recognition module 40 may include a central processing unit (CPU), an audio processor (AudioProcessor), etc., but the present invention is not limited thereto. Therefore, compared with the voice input module 10 (which may include, for example, a microphone) and the wake-up module 30 (which may include, for example, an audio codec and other simple hardware circuits), the voice recognition module 40 consumes more power when running. Therefore, for the electronic device, the device location prompting system 1 provided in this embodiment does not consume a lot of power. The main reason is that when the device location prompting system 1 operates in the first mode, only voice The input module 10 and the wake-up module 30 work, but the voice recognition module 40 is not. It is also worth noting that the device location reminder system 1 does not need to be controlled by an additional electronic device to operate, that is, the user does not need to operate the device location reminder system 1 by using an additional electronic device to find the location of the lost electronic device. .

[Another embodiment of the device location notification system]

In the following description, another embodiment is used to illustrate the device location prompting system of the present invention. Please refer to FIG. 2 , which is a block diagram of a device location prompting system according to another exemplary embodiment of the present invention. The device location prompting system 2 provided in this embodiment has a similar module structure and working principle to the device location prompting system 1 shown in FIG. ), an audio processor (AudioProcessor), etc. The voice recognition module 40 in the device position prompting system 2 further includes a timing unit 42 . When the device position prompting system 2 starts to operate in the second mode, the timing unit 42 then counts a predetermined period of time. If the voice recognition module 40 does not determine that the audio data read by the storage module 50 has a default control sentence in the default time, the voice recognition module 40 will automatically stop working (ie, the device location The prompt system 2 will automatically return to the first mode to operate). For example, when the user inadvertently makes a sound with a threshold amplitude greater than or equal to a threshold amplitude to cause the device position prompting system 2 to enter the second mode, or after the user makes the device position prompting system 2 enter the second mode, it is found that there is no When the electronic device needs to be searched, after a default period of time, because the voice recognition module 40 cannot detect the control sentence input by the user, the voice recognition module 40 will automatically stop running, so that the device position prompting system 2 returns to the first. mode to avoid draining the power of the electronic device.

Next, the basic structure and working principle of the voice input module 10 in the device position prompting system 2 provided in this embodiment will be further described.

As shown in FIG. 2 , the voice input module 10 at least includes an analog-to-digital converter 12 and a temporary memory 14 , wherein the temporary memory 14 is connected to the analog-to-digital converter 12 . In addition, the wake-up module 30 includes at least a comparator 32 , wherein the comparator 32 is connected to the temporary memory 14 of the voice input module 10 . In the first mode, the analog-to-digital converter 12 converts an audio data received by the voice input module 10 into a signal, that is, an analog signal is converted into a digital signal, and the converted audio data is temporarily stored in the temporary memory. body 14. For example, the temporary storage memory 14 may be a First In First Out (FIFO) temporary storage memory, but the invention is not limited thereto. The comparator 32 in the wake-up module 30 reads the audio data temporarily stored in the temporary memory 14 of the voice input module 10, and compares whether the amplitude of the audio data is greater than or equal to a threshold amplitude of a trigger level. On the other hand, in the second mode, the analog-to-digital converter 12 also converts the audio data of the voice input module 10 into a signal, that is, converts an analog signal into a digital signal, however, the converted audio data will be stored in the In the storage module 50, the voice recognition module 40 reads and judges whether there is a control sentence set by the user in the audio data.

In addition, in this embodiment, the initial setting of the trigger level used to determine the threshold amplitude and the control statement can be completed by the electronic device manufacturer when the system leaves the factory, but these initial settings can be changed by the user , or the user downloads and installs the application program, and then changes the setting, which is not limited in the present invention. That is, the user can adjust the trigger level of the comparator 32 of the wake-up module 30 to change the setting of the threshold amplitude. In addition, the user can change the setting of the control sentence and store it in the storage module 50 for the voice recognition module 40 to compare the audio data with the control sentence, so as to determine whether there is a control sentence in the audio data. For example, the user can change the initially set control sentence through an operation interface corresponding to the device position prompting system 2 and the voice input module 10 established on the electronic device, and store the changed control sentence in the storage module 50 .

Like the device position prompting system 1 in the foregoing embodiment, as long as the electronic device provided with the device position prompting system 2 is turned on, the user can find where the electronic device is placed by voice control at any time.

Furthermore, in this embodiment, the speech recognition module 40 may include a central processing unit (CPU), an audio processor (Audio Processor), etc., but the present invention is not limited thereto. Therefore, compared with the voice input module 10 (which may include, for example, a microphone) and the wake-up module 30 (which may include, for example, an audio codec and other simple hardware circuits), the voice recognition module 40 consumes more power when running. Therefore, for the electronic device, the device location prompting system 2 provided in this embodiment has lower power consumption, the main reason being that when the device location prompting system 2 operates in the first mode, only the voice input module 10 is required. The wake-up module 30 is working, while the voice recognition module 40 is not working. Another reason is that, in addition, if the voice recognition module 40 does not determine that the audio data read by the storage module 50 has a control sentence preset by the user within a default period of time, the voice recognition module 40 will Automatically stop working, so that the device position notification system 2 automatically returns to the first mode to operate, so as to avoid consuming the power of the electronic device. In addition, the device location prompting system 2 does not need to be controlled by an additional electronic device to operate, that is, the user does not need to use the additional electronic device to operate the device location prompting system 2 to find the location of the lost electronic device.
