Description

Technical Field

[0001] The present invention relates to the technical field of hearing aids, and in particular to a connection and loss monitoring system and method for hearing aids. Background Art

[0002] With the advancement of technology and the aging of the population, hearing aids, as important hearing aids, play an increasingly important role in people's daily lives. However, most traditional hearing aids can only provide basic hearing amplification functions, and pay little attention to the actual needs and experience of users. Especially in terms of wireless connection and intelligence, traditional hearing aids often seem to be unable to meet their expectations.

[0003] In the current hearing aid market, although some products have begun to try to introduce wireless connection technology, most of these technologies remain at the simple audio transmission level and lack real-time monitoring and effective management of the wireless connection status of hearing aids. For example, when a user's hearing aid is accidentally lost or exceeds the effective use range, the other hearing aid often cannot give a prompt, causing the user to spend a lot of time and energy to find the lost hearing aid. This not only brings great inconvenience to the user, but may also cause unnecessary economic losses due to the loss of the hearing aid.

[0004] In addition, existing hearing aids also have many deficiencies in the lost reminder function. Although some products provide simple sound reminders, they often lack sufficient intelligent and personalized settings. For example, the volume, frequency and other parameters of the reminder sound are often unable to be adjusted according to the actual needs of the user, resulting in unsatisfactory reminder effects. At the same time, these products also lack the distinction between different levels of urgency, and cannot give sufficiently obvious reminders in the early stages of hearing aid loss, thus missing the best time to find the hearing aid. Summary of the invention

[0005] The purpose of the present invention is to provide a connection and loss monitoring system and method for hearing aids, which can monitor the connection status between hearing aids in real time and remind the user when they may be lost, thereby improving the convenience, safety and user experience of hearing aids.

[0006] To achieve the above object, the present invention provides a connection and loss monitoring system for a hearing aid, comprising:

[0007] Two hearing aids, each hearing aid is integrated with a wireless connection module, the wireless connection module supports a heartbeat packet sending and receiving mechanism, and is used to achieve wireless connection and communication between the two hearing aids;

[0008] Heartbeat packet sending and receiving mechanism, setting one of the hearing aids as the main device and the other as the auxiliary device, the main device sends a heartbeat packet to the auxiliary device, and the auxiliary device sends a response signal to the main device after receiving the heartbeat packet;

[0009] A lost reminder module, when the main device determines that the auxiliary device is out of use or may be lost, or when the auxiliary device determines that the main device is out of use or may be lost, the lost reminder mechanism is activated to remind the user;

[0010] Interval silence module, any hearing aid will automatically enter sleep mode after 25-35 minutes;

[0011] The intelligent control system is used to manage the working status of the wireless connection module, the heartbeat packet sending and receiving mechanism, and the lost reminder module and the interval silence module.

[0012] Preferably, the heartbeat packet sending and receiving mechanism includes a heartbeat packet sending module, a heartbeat packet receiving module and a timeout detection module;

[0013] The heartbeat packet sending module performs a heartbeat packet sending operation every preset time T1, the heartbeat packet receiving module performs a response signal receiving operation in the interrupt, and the timeout detection module performs a timeout detection operation every preset time T2;

[0014] When the master device fails to receive the response signal from the slave device for CNT consecutive times, it determines that the slave device is lost;

[0015] When the slave device does not receive CNT heartbeat packets from the master device within T2, it determines that the master device is lost;

[0016] The calculation formula of CNT is as follows:

[0017] CNT=T2 / T1.

[0018] Preferably, the value range of T1 is 5 to 50 ms, and the value range of T2 is 500 ms to 2 s.

[0019] Preferably, the lost reminder mechanism includes two modes: an alarm sound and a flashing indicator light.

[0020] Preferably, the intelligent control system is set through a matching mobile terminal APP, including setting the sending frequency of heartbeat packets, the number of consecutive unreceived heartbeat packets, the alarm tone type, and the alarm tone volume.

[0021] Based on the above-mentioned connection and loss monitoring system for hearing aids, the present invention also provides a connection and loss monitoring method for hearing aids, comprising the following steps:

[0022] Step S1, integrating wireless connection modules into two hearing aids respectively to achieve wireless connection and communication between the two;

[0023] Step S2: Set one hearing aid as the primary device and the other as the secondary device. The primary device periodically sends a heartbeat packet to the secondary device. After receiving the heartbeat packet, the secondary device sends a response signal to the primary device.

[0024] Step S3: When the master device does not receive a response signal from the slave device after sending CNT heartbeat packets continuously, it is determined that the slave device is out of use or has been lost;

[0025] When the slave device does not receive CNT heartbeat packets from the master device within T2, it determines that the master device is out of use or has been lost;

[0026] Step S4: When it is determined that the auxiliary device is out of use or has been lost, the lost reminder mechanism is activated, and the main device reminds the user by sounding an alarm and flashing an indicator light;

[0027] When it is determined that the main device is out of use or has been lost, the lost reminder mechanism is activated, and the auxiliary device reminds the user by emitting an alarm sound and flashing an indicator light.

[0028] Preferably, an active anti-loss method controlled by an interval silence module is also included: when any hearing aid enters the sleep mode, the user actively touches the hearing aid, so that the hearing aid enters the normal working mode.

[0029] Preferably, CNT is cleared before any hearing aid enters sleep mode.

[0030] Therefore, the present invention adopts the above-mentioned system and method for monitoring connection and loss of hearing aids, and the beneficial technical effects are as follows:

[0031] (1) Real-time monitoring and instant reminder: By integrating the wireless connection module and the heartbeat packet sending and receiving mechanism, the system can monitor the wireless connection status between the two hearing aids in real time. Once one of the hearing aids is out of range or may be lost, the system will immediately activate the lost reminder mechanism to remind the user by sounding an alarm and flashing an indicator light, thus effectively avoiding the inconvenience and economic losses caused by the loss of the hearing aid.

[0032] (2) Intelligent and personalized settings: The system provides intelligent settings. Users can flexibly set and adjust parameters such as the frequency of sending heartbeat packets, the number of consecutive heartbeat packets not received, the type of alarm sound, and the volume of the alarm sound according to their actual needs through the supporting mobile terminal APP. This personalized setting not only improves the applicability and user experience of the system, but also makes the reminder method more in line with the actual needs of users.

[0033] (3) Improve search efficiency: The lost reminder mechanism can give a sufficiently obvious reminder at the early stage of the lost hearing aid by emitting alarm sounds and flashing indicator lights of different urgency, thereby improving the efficiency of users in finding lost hearing aids. At the same time, this reminder method can also provide users with timely help and guidance in emergency situations.

[0034] (4) Enhanced user experience: By integrating wireless connection, real-time monitoring, and intelligent settings, the system provides users with a more convenient and intelligent user experience. Users no longer need to worry about losing their hearing aids and can focus more on their daily life and work.

[0035] (5) The interval silence module allows any hearing aid to enter sleep mode automatically after an interval of 25-35 minutes. This is an effective energy-saving measure and also provides users with an active anti-lost mechanism. When the hearing aid enters sleep mode, if the user needs to continue using it, they need to touch the hearing aid to restore it to normal working mode. This design not only extends the use time of the hearing aid, but also increases the user's chance of finding the hearing aid if it is lost, because the user will realize that the hearing aid has entered sleep mode and actively look for it. In addition, before entering sleep mode, the system will clear the number of consecutive times that the heartbeat packet has not been received (CNT) to avoid misjudgment due to sleep.

[0036] (6) The system of the present invention integrates both active and passive anti-loss methods, which is completely different from the hearing aids in the prior art. BRIEF DESCRIPTION OF THE DRAWINGS

[0041] The technical solution of the present invention is further described below through the accompanying drawings and embodiments.

[0042] Unless otherwise defined, technical or scientific terms used in the present invention shall have the common meanings understood by one having ordinary skills in the field to which the present invention belongs.

[0043] Embodiment 1

[0044] like Figure 1 As shown, the present invention provides a connection and loss monitoring system for hearing aids, including two hearing aids and an intelligent control system. A wireless connection module and a loss reminder module are integrated in each hearing aid.

[0045] The wireless connection module is provided with a heartbeat packet sending and receiving mechanism, supports the heartbeat packet sending and receiving mechanism, and is used to realize wireless connection and communication between two hearing aids.

[0046] The heartbeat packet sending and receiving mechanism sets one hearing aid as the main device and the other as the auxiliary device. The main device periodically sends heartbeat packets to the auxiliary device, and the auxiliary device sends a response signal to the main device after receiving the heartbeat packet.

[0047] The heartbeat packet sending and receiving mechanism includes a heartbeat packet sending module, a heartbeat packet receiving module and a timeout detection module.

[0048] The working procedures of the heartbeat packet sending module and the heartbeat packet receiving module are as follows: Figure 2 , Figure 3 shown. Figure 2 In the example, Count++ indicates the operation of increasing the number of heartbeat packet sending times by one. Figure 3 In the example, Count=0 indicates a reset operation; ACK is a heartbeat packet response signal sent from the auxiliary earphone to the main earphone.

[0049] The heartbeat packet sending module performs a heartbeat packet (agreed bit rate) sending operation every preset time T1, the heartbeat packet receiving module performs a response signal receiving operation in an interrupt, and the timeout detection module performs a timeout detection operation every preset time T2.

[0050] When the master device fails to receive a response signal (agreed bit rate) from the slave device for CNT consecutive times, it determines that the slave device is lost.

[0051] When the slave device does not receive CNT heartbeat packets from the master device within T2 time, it determines that the master device is lost.

[0052] The calculation formula of CNT is as follows:

[0053] CNT=T2 / T1.

[0054] The value range of T1 is 5 to 50 ms, and the value range of T2 is 500 ms to 2 seconds.

[0055] The lost reminder module starts the lost reminder mechanism to remind the user when the main device determines that the auxiliary device is out of the scope of use or may be lost, or when the auxiliary device determines that the main device is out of the scope of use or may be lost.

[0056] The lost reminder mechanism includes two modes: alarm sound and flashing indicator light. The alarm sound and flashing indicator light are divided into several levels N according to the degree of urgency. The larger N is, the higher the volume and frequency of the alarm sound, the faster the indicator light flashes, and the color of the indicator light also changes with the size of N.

[0057] In the interval silence module, any hearing aid will automatically enter the sleep mode after 25-35 minutes. At this time, the user will touch the hearing aid actively because they cannot hear the outside sound normally, so that the hearing aid enters the normal working mode. This is an active anti-lost mechanism. CNT is cleared before entering the sleep mode.

[0058] The intelligent control system is used to manage the working status of the wireless connection module, the heartbeat packet sending and receiving mechanism, the interval silence module and the lost reminder module.

[0059] The intelligent control system is set up through the supporting remote terminal APP, including setting the sending frequency of heartbeat packets, the number of consecutive heartbeat packets not received, the alarm tone type, and the alarm tone volume.

[0060] Embodiment 2

[0061] like Figure 4 As shown, a method for monitoring connection and loss of a hearing aid comprises the following steps:

[0062] Step S1: Integrate wireless connection modules into two hearing aids respectively to achieve wireless connection and communication between the two.

[0063] Step S2: set one hearing aid as the main device and the other as the auxiliary device. The main device periodically sends a heartbeat packet to the auxiliary device. After receiving the heartbeat packet, the auxiliary device sends a response signal to the main device.

[0064] Step S3: When the master device does not receive a response signal from the slave device after sending CNT heartbeat packets continuously, it is determined that the slave device is out of use or has been lost.

[0065] When the slave device does not receive CNT heartbeat packets from the master device within T2 time, it determines that the master device is out of use or has been lost.

[0066] Step S4: When it is determined that the auxiliary device is out of use or has been lost, the lost reminder mechanism is activated, and the main device reminds the user by emitting an alarm sound and flashing an indicator light.

[0067] When it is determined that the main device is out of use or has been lost, the lost reminder mechanism is activated, and the auxiliary device reminds the user by emitting an alarm sound and flashing an indicator light.

[0068] The lost monitoring method also includes an active anti-lost method controlled by an interval silence module: when any hearing aid enters sleep mode, the user actively touches the hearing aid, so that the hearing aid enters normal working mode. CNT is cleared before any hearing aid enters sleep mode.

[0069] It is worth noting that the contents not elaborated in detail in the present invention are all prior art and are well known to those skilled in the art.

[0070] Therefore, the present invention adopts the above-mentioned connection and loss monitoring system and method for hearing aids, which can monitor the connection status between hearing aids in real time and remind the user when they may be lost, thereby improving the convenience, safety and user experience of hearing aids.

[0071] Finally, it should be noted that the above embodiments are only used to illustrate the technical solution of the present invention rather than to limit it. Although the present invention has been described in detail with reference to the preferred embodiments, those skilled in the art should understand that they can still modify or replace the technical solution of the present invention with equivalents, and these modifications or equivalent replacements cannot cause the modified technical solution to deviate from the spirit and scope of the technical solution of the present invention.
