detailed description

FIG. 1 is a functional block diagram of a communication system according to an embodiment of the present invention. Referring to FIG. 1 , the communication system 10 includes a main electronic device 110 and an auxiliary electronic device 120 . The accessory electronic device 120 transmits the connection sound wave signal CSW. When the main electronic device receives the connection sound wave signal CSW, it sends the positioning signal PS according to the connection sound wave signal CSW. When the auxiliary electronic device 120 receives the positioning signal PS, it sends the positioning acoustic wave signal PSW to the main electronic device 110 . And, the main electronic device 110 judges the relative position between the auxiliary electronic device 120 and the main electronic device 110 according to the positional sound wave signal PSW, and displays the operation icon on the display unit of the main electronic device 110 according to the relative position.

In this embodiment, in order to prevent the sound waves from affecting the user, the connection sound wave signal CSW is a sound wave with a frequency beyond the human ear, for example, the frequency value is set outside the frequency band of 20 Hz to 20,000 Hz. Wherein, the auxiliary electronic device 120 can carry specific information in the connection sound wave signal CSW. For example, in this embodiment, the connection acoustic wave signal CSW includes connection information. When the main electronic device 110 receives the connection sound wave signal CSW, the main electronic device 110 analyzes the connection sound wave signal CSW to obtain connection information, and establishes a connection with the auxiliary electronic device 120 according to the connection information. The main electronic device 110 then transmits the positioning signal PS through the connection.

The content of the connection information varies with the type of connection established between the main electronic device 110 and the auxiliary electronic device 120 (for example, a connection established with a signal conforming to a certain standard). The above connection is an example of a connection established by a radio frequency signal conforming to the bluetooth standard, and the connection information may include the Media Access Control (MAC for short) of the accessory electronic device 120 corresponding to the bluetooth standard. ) address, device name and device pairing code of the accessory electronic device 120 .

On the other hand, in the present invention, entraining information (for example, the above-mentioned connection information) in the connection sound wave signal CSW can also be realized in various ways. For example, the preset frequency band is cut into multiple different frequency values, and the frequency values of different sizes represent different characters sequentially. For example, when the preset frequency band is cut into 16 different frequency values, the frequency band It can be used to transmit hexadecimal data (for example, the MAC address of the above-mentioned accessory electronic device 120 ). In practice, the preset frequency band may be divided into more frequency values, for example, 16 frequency values are used to represent hexadecimal data, and other frequency values are used to represent the initial character, Functional characters such as end characters and space characters, but the present invention is not limited to the above.

FIG. 2 is a device block diagram showing an electronic device according to an embodiment of the invention. Wherein, the electronic device shown in FIG. 2 corresponds to the main electronic device 110 in the communication system shown in FIG. 1 . Referring to FIG. 2 , the electronic device 110 includes a communication unit 111 , a sound receiving unit 112 , a processing unit 113 and a display unit 114 . The processing unit 113 is coupled to the communication unit 111 and the sound receiving unit 112 . The display unit 114 is coupled to the processing unit 113 . When the sound receiving unit 112 receives the connection sound wave signal CSW, the processing unit 113 sends the positioning signal PS through the communication unit 111 according to the connection sound wave signal CSW. For example, as in the above-mentioned embodiment, the connection information in the connection sound wave signal CSW is used to connect with the auxiliary electronic device (eg, the auxiliary electronic device 120 in FIG. 1 ), and then use this connection to transmit the positioning signal PS.

When the processing unit 113 receives the positioning acoustic wave signal PSW corresponding to the positioning signal PS through the sound receiving unit 112, the processing unit 113 judges the auxiliary electronic device (for example, the auxiliary electronic device 120 in FIG. 1 ) that sends the positioning acoustic wave signal PSW according to the positioning acoustic wave signal PSW. The relative position between the electronic device 110 and the processing unit 113 controls the display unit 114 to display the operation icon according to the relative position.

In this embodiment, the sound receiving unit 112 may include at least two sound receivers (not shown), and the processing unit 113 may judge the attachment of The relative position of the electronic device and the electronic device 110 . And because in the present invention, the above-mentioned connection sound wave signal CSW and positioning sound wave signal PSW are all set in the frequency band outside the frequency that can be recognized by the human ear, so the above-mentioned receiver must be provided with corresponding connection sound wave signal CSW and Only a high pass filter (high pass filter) or a band pass filter (band pass filter) in the frequency band of the positioning sound wave signal PSW can successfully receive the above-mentioned connection sound wave signal CSW and positioning sound wave signal PSW, but the present invention is not limited to The above settings may be changed due to different implementations.

Furthermore, after the processing unit 113 determines the relative position of the accessory electronic device and the electronic device 110, the processing unit 113 can display the operation icon corresponding to the accessory electronic device on the display unit 114 according to the relative position of the accessory electronic device and the electronic device 110. . For example, the display unit 114 of the electronic device 110 is rectangular, and when the relative position of the accessory electronic device and the electronic device 110 corresponds to the side of the rectangular display unit 114, the processing unit 113 can display the operation icon on the side adjacent to the display unit 114. This side, and adjust the position of the operation icon according to the actual position.

For example, when the processing unit 113 of the electronic device 110 determines that the auxiliary electronic device is located on the left side of the electronic device 110, the processing unit 113 can display the operation icon corresponding to the auxiliary electronic device on the display unit 114 of the electronic device 110. on the left side, and adjust the position of the operation icon on the left side according to the position of the attached electronic device. The icon style of the operation icon can be determined according to the type of the attached electronic device (for example, it can be obtained from the connection information in the connection sound wave signal CSW), so that the user can directly display the display unit 114 according to the style of the operation icon and the operation icon. The position of the operation icon is used to determine the accessory electronic device corresponding to the operation icon.

And when the processing unit 113 receives the operation signal corresponding to the operation icon, for example, the user uses the input and output unit of the electronic device 110 (the touch screen, touch panel, mouse or keyboard of the electronic device 110, etc., not shown), click When the above operation icon is selected, the processing unit 113 can utilize the connection established between the communication unit 111 in the electronic device 110 and the accessory electronic device to execute the file transfer procedure. The file transfer procedure may include the exchange of files or data between the electronic device 110 and the accessory electronic device.

For example, the file transfer program may include a display interface, so that when the user uses the input and output unit of the electronic device 110 to click the operation icon corresponding to the accessory electronic device, the processing unit 113 can display the display interface of the file transfer program through the display unit 114 . The display interface can include the file list of the attached electronic device, etc., and the user can complete the file by dragging the icon corresponding to the file data to the display interface, dragging the icon corresponding to the file data from the display interface, or other operation methods transmission or exchange.

In the above-mentioned embodiments, there is only one accessory electronic device (such as the accessory device 120 in FIG. 1 ). In fact, in the present invention, the main electronic device 110 (the electronic device shown in FIG. 2 ) can also identify and connect multiple auxiliary electronic devices at the same time through the above-mentioned embodiment. In the following, the situation that the main electronic device 110 is connected to multiple auxiliary electronic devices will be described through embodiments and drawings.

Fig. 3 is a sequence diagram showing a communication system according to an embodiment of the present invention. Please refer to FIG. 3 , where if the signals transmitted between the devices are sound wave signals, such as the connection sound wave signal CSW or the positional sound wave signal PSW shown in FIG. 1 , they are shown in dotted lines in FIG. 3 . If the signals transmitted between the various devices are transmitted through connection lines, it is indicated by a solid line.

The communication system 10 includes a main electronic device 110 and auxiliary electronic devices 120 , 130 . The central frequency of the connection sound wave signal can be preset in the main electronic device 110 and the auxiliary electronic devices 120 , 130 . The accessory electronic device 120 first utilizes the receiver (not shown) of the accessory electronic device 120 to monitor the frequency band near the central frequency of the current connection sound wave signal (or even locate the possible frequency range of the sound wave signal) to see if there are other sound wave signals (step S301 ). If not, the accessory electronic device 120 transmits the first connection sound wave signal to the main electronic device (step S302 ).

The main electronic device 110 continuously monitors the connection sound wave signal and locates the frequency range of the sound wave signal. When receiving the first connection sound wave signal sent by the auxiliary electronic device 120, the main electronic device 110 analyzes the first connection sound wave signal. The first connection information is obtained, and a connection is established with the accessory electronic device 120 according to the first connection information (step S303 ). After the connection with the auxiliary electronic device 120 is established, the main electronic device 110 can use the connection to transmit the first positioning signal to the auxiliary electronic device 120 (step S304 ).

When the auxiliary electronic device 120 receives the first positioning signal through the above-mentioned connection, the auxiliary electronic device 120 analyzes the first positioning signal to obtain necessary information, such as the center frequency or frequency of the positioning acoustic wave signal specified by the main electronic device 110 range etc. (step S305). In this embodiment, after analyzing the first positioning signal, the auxiliary electronic device 120 will send an acknowledgment (ACK) signal to the main electronic device 110 through the above connection to notify the main electronic device 110 that the first positioning signal has been detected. Successfully received (step S306). Moreover, the accessory electronic device 120 also transmits the first positional acoustic wave signal at the same time, for example, according to the necessary information in the first positional signal (step S307 ). When the main electronic device 110 receives the ACK signal from the auxiliary electronic device 120 through the connection, and receives the first positional acoustic wave signal through the radio unit (for example, the radio unit 112 in FIG. 2 ), it can use the first positional acoustic wave signal to judge the auxiliary electronic device. The relative position of 120 (ie, the first relative position) is judged, for example, by the phase difference received by several radios in the radio unit. Furthermore, the main electronic device 110 can display the first operation icon corresponding to the auxiliary electronic device 120 on the display unit (such as the display unit 114 in FIG. 2 ) of the main electronic device 110 according to the above relative position.

On the other hand, the accessory electronic device 130 also utilizes the receiver (not shown) of the accessory electronic device 130 to monitor the frequency band near the central frequency of the current connection sound wave signal (or even locate the possible frequency range of the sound wave signal) to see if there are other sound waves signal (step S309). At this time, the accessory electronic device 130 has received the sound wave signal sent by other electronic devices (that is, the first connection sound wave signal sent by the accessory electronic device 120), and the accessory electronic device 130 waits for a preset time (step S310 ), and then re-judging whether there are sound wave signals sent by other electronic devices at this time (step S311), if not, the auxiliary electronic device 130 transmits the second connection sound wave signal to the main electronic device (step S312).

The main electronic device 110 also continuously monitors the frequency range of the connection sound wave signal and the positioning sound wave signal. When receiving the second connection sound wave signal sent by the auxiliary electronic device 130, the main electronic device 110 analyzes the second connection sound wave signal. The signal obtains the second connection information, and establishes a connection with the accessory electronic device 130 according to the second connection information (step S312 ). After the connection with the auxiliary electronic device 130 is established, the main electronic device 110 can use the connection to transmit the second positioning signal to the auxiliary electronic device 130 (step S314 ).

When the accessory electronic device 130 receives the first positioning signal through the aforementioned connection, the accessory electronic device 130 analyzes the second positioning signal and obtains necessary information (step S315 ). After analyzing the second positioning signal, the auxiliary electronic device 130 will also send an ACK signal to the main electronic device 110 through the above connection to notify the main electronic device 110 that the second positioning signal has been successfully received (step S316 ). Moreover, the accessory electronic device 130 also transmits the second positional acoustic wave signal at the same time (step S317 ). When the main electronic device 110 receives the ACK signal from the accessory electronic device 130 through the connection, and receives the second positional acoustic wave signal through the radio unit, the main electronic device 110 can use the second positional acoustic wave signal to determine the relative position of the auxiliary electronic device 130 ( i.e., the second relative position). Furthermore, the main electronic device 110 can display the second operation icon corresponding to the auxiliary electronic device 130 on the display unit of the main electronic device 110 according to the above-mentioned relative position.

It is worth noting that, in this embodiment, since the transmission of sound waves in the air is easily disturbed by environmental factors, the main electronic device 110 must receive the ACK signal returned from the same auxiliary electronic device (such as the auxiliary electronic device 120) at the same time And the positioning acoustic wave signal (for example, the first positioning acoustic wave signal), the main electronic device 110 will judge the relative position of the auxiliary electronic device according to the positioning acoustic wave signal, so as to reduce the probability of misjudging the relative position of the auxiliary electronic device.

On the other hand, after the above-mentioned steps S301-S318 are completed, the relative positions of the main electronic device 110 and the auxiliary electronic devices 120, 130 may still change, for example, due to the movement of the user. Therefore, after the main electronic device 110 establishes connection with the auxiliary electronic devices 120 and 130 respectively, the steps S304-S308 and S314-S318 corresponding to locating the auxiliary electronic devices 120 and 130 will be executed periodically. That is to say, the main electronic device 110 will continue to periodically send positioning signals (for example, the first positioning signal and the second positioning signal) to continuously update the location corresponding to each auxiliary electronic device (for example, the auxiliary electronic devices 120 and 130 ). The location displayed on the display unit of the main electronic device 110 .

The main electronic device 110 may periodically and continuously send the above-mentioned positioning signal in various ways, for example, sending the above-mentioned positioning signal in a broadcast or polling manner. For the mechanism of broadcasting the positioning signal, the main electronic device 110 can integrate all the information provided to the auxiliary electronic devices into a single positioning signal, and when each auxiliary electronic device receives the positioning signal, it analyzes the information corresponding to Necessary information for each accessory electronic device. For example, the first positioning signal and the second positioning signal shown in FIG. 3 are integrated into a single positioning signal, and the positioning signal is sent to the auxiliary electronic devices 120 and 130 at the same time.

However, if the positioning signal is transmitted by broadcasting, the main electronic device 110 must specify the center frequency or frequency range of the positioning acoustic wave signal corresponding to each auxiliary electronic device in the positioning signal, so that the main electronic device 110 can successfully distinguish each auxiliary electronic device. The returned positioning acoustic wave signal. But in this way, since each auxiliary electronic device may return the positioning acoustic wave signal at the same or close time point, the main electronic device 110 must simultaneously monitor multiple frequency ranges and analyze the positioning acoustic wave signal in each frequency range, so that The calculation complexity of the actions to be analyzed may be high, which may cause a high calculation burden on the main electronic device 110 .

On the other hand, for the mechanism of sending positioning signals in a polling manner, the main electronic device 110 sends positioning signals to each auxiliary electronic device in turn, and after the relative position of the auxiliary electronic devices is judged/updated, the main electronic device 110 sends again A positioning signal corresponding to another accessory electronic device. Wherein, since the main electronic device 110 only receives the positional acoustic wave signal returned from a single auxiliary electronic device at a single time, the positional acoustic wave signal returned by each auxiliary electronic device can be located at the same frequency or at a different frequency. frequency. The main electronic device 110 can set the center frequency or frequency range of the positioning acoustic wave signal through positioning signals (such as the first positioning signal and the second positioning signal), and can also dynamically adjust the center frequency or frequency range of the positioning acoustic wave signal according to the surrounding environment.

For example, in the embodiment shown in FIG. 3, the main electronic device 110 first transmits the first positioning signal, and receives the first positioning acoustic wave signal (and the ACK signal) returned by the auxiliary electronic device 120 corresponding to the first positioning signal. ) determine/update the first relative position and correspondingly update the position of the first operation icon on the display unit (steps S304-S308), and then transmit the second positioning signal, and then receive the corresponding second positioning signal from the auxiliary electronic device 130 The returned second positional acoustic wave signal (and ACK signal) is used to determine/update the second relative position and correspondingly update the position of the second operation icon on the display unit (steps S314 - S318 ). Then, the main electronic device 110 periodically and continuously executes steps S304-S308 and steps S314-S318 to track the relative positions of the auxiliary electronic devices 120, 130 and the main electronic device 110 (the first relative position, the second relative position), and update the positions of the first operation icon and the second operation icon on the display unit of the main electronic device 110 .

On the other hand, in this embodiment, if the main electronic device 110 does not receive the ACK signal within a preset time after sending the positioning signal (for example, the first positioning signal), except that the surrounding interference is too high and the ACK signal cannot be normal The transmission to the main electronic device 110 may also be caused by an auxiliary electronic device (eg, the auxiliary electronic device 120 ) being moved away from the main electronic device 110 by the user, resulting in disconnection of the connection. Therefore, in this embodiment, the main electronic device 110 retransmits the positioning signal several times (ie, transmits a preset number of positioning signals at a preset time interval).

If the main electronic device 110 has not received the ACK signal returned by the auxiliary electronic device, the main electronic device 110 will continue to send positioning signals, but gradually lengthen the time interval between the positioning signals until it receives the ACK signal returned by the auxiliary electronic device. The returned ACK signal re-judges the relative position of the auxiliary electronic device and the main electronic device 110, and then resumes sending positioning signals at the original preset time interval. The present invention is not limited to the above-mentioned settings. For example, when the main electronic device 110 transmits a predetermined number of positioning signals but does not receive any ACK signal, it directly disconnects the connection with the auxiliary electronic device and no longer sends corresponding signals. Here, the positioning signal of the attached electronic device may be combined in the above two implementations (gradually increasing the time interval, and disconnecting the connection and sending the positioning signal after a predetermined number), but the present invention is not limited to the above-mentioned configuration.

In the embodiment shown in FIG. 3 , the auxiliary electronic devices connected to the main electronic device 110 are only the auxiliary electronic devices 120 and 130, but in fact, the above-mentioned detection, connection and The manner of determining the relative position makes the communication system 10 include more auxiliary electronic devices, and the present invention is not limited to the above-mentioned arrangement and the number of auxiliary electronic devices.

Please refer to FIG. 4 , first in step S401 , when receiving a first connection sound wave signal, a first positioning signal is sent according to the first connection sound wave signal. Then in step S402, when receiving the first positional acoustic wave signal corresponding to the first positional acoustic wave signal, judge the first relative position between the first accessory electronic device and the electronic device that sent the first positional acoustic wave signal according to the first positional acoustic wave signal . Next, in step S403, the display unit is controlled to display the first operation icon according to the first relative position. As for the detailed implementation of the communication method, reference may be made to the above descriptions in FIGS. 1 to 3 , which will not be repeated here.

In the present invention, the names of the main electronic device 110 and the auxiliary electronic devices 120 and 130 are only used to distinguish the master-slave relationship between the electronic devices when transmitting information in the communication system. The main electronic device 110 and the auxiliary electronic devices 120 and 130 can be any electronic devices, such as smart phones, tablet computers, notebook computers, personal computers, or digital cameras.

But among them, the electronic device as the main electronic device must at least include a radio unit that can receive sound waves and use sound waves to determine the relative position (for example, a radio unit that includes at least two radio receivers at a certain distance), and has a filter connection A filter for the acoustic signal, the ability to localize the acoustic signal. As an accessory electronic device, the electronic device must at least have a speaker capable of transmitting and localizing sound wave signals, a radio unit and a filter for monitoring the frequency range of the connecting sound wave signals and localizing sound wave signals. For other settings, reference may be made to the above-mentioned embodiments, which will not be repeated here.
