Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of Bluetooth assistive listening, and in particular to a low-power control method for Bluetooth assistive listening earphones. BACKGROUND

[0002] Bluetooth assistive listening earphones have emerged as a product of the times different from traditional hearing aids, and are between medical and consumer electronics. As modern health care assistive listening electronic devices, they achieve direct connection with smartphones through wireless Bluetooth communication functions. On the one hand, they realize hearing test and fitting functions for users through the APP developed on the smartphone, generate different frequency band gain compensation curves according to the audiometry results, and completely eliminate the need for professional store fitting, so as to further improve the quality of life with the help of technology. On the other hand, they can be switched to a multimedia state to enjoy the fun of wireless Bluetooth music in a quiet time. With the deployment and popularization of public place Bluetooth broadcasting, Bluetooth assistive listening earphones are connected with public Bluetooth terminals, so that users can hear more clearly in a noisy environment and not miss the information they need. This makes the function more powerful and the application more close to daily needs.

[0003] The emergence of Bluetooth assistive listening earphones solves many pain points of current assistive listening products and raises the most concerned basic problem, that is, power consumption. At present, due to the numerous functions of such products and the complexity of internal function modules of the system, in the long-term assistive listening mode, the left and right earphones are linked to multimedia Bluetooth devices, and through radio frequency scanning and Bluetooth continuous communication, a large amount of power consumption is lost. In actual use test, the power consumption is about 5-6 mA when the Bluetooth multimedia function works, and the power consumption reaches about 7 mA in the assistive listening and Bluetooth working state, which is the main aspect of power consumption, greatly reduces the assistive listening working time, and causes frequent charging of users, resulting in poor experience. SUMMARY

[0004] The low-power control method for Bluetooth assistive listening earphones proposed in the present application can at least solve one of the above technical problems.

[0005] To achieve the above-mentioned purpose, the present application adopts the following technical solutions:

[0006] A low-power control method for Bluetooth assistive listening earphones, comprising the following steps,

[0007] S101: After the left and right earphones are enabled, they automatically enter a Bluetooth ear-to-ear pairing mode, achieve an ear-to-ear connection state, and connect with a test and fitting smartphone and participate in interactive operation according to a Bluetooth broadcast frequency scanning mode;

[0008] S102: The earphone is connected with the multimedia mobile phone, is automatically recognized, and is manually entered into a fitting mode, during which the whole machine is in a Bluetooth mode, and the assistive listening function is also supported to work synchronously, and the wireless Bluetooth fitting function is performed.

[0009] S103: After APP data implantation, the assistive listening function is directly entered; through left and right earphone broadcast protocol communication, long-time interval broadcast scanning communication in double-ear connection is realized, the double ears are interconnected, and according to the setting of the internal transmission power, the main earphone and the multimedia device are disconnected in a range greater than two meters.

[0010] Further, when the earphone-to-ear connection is disconnected, the main earphone and the multimedia device are also disconnected, and the Bluetooth sweep frequency mode is closed.

[0011] Further, after each use, if the left and right earphones are paired or have been connected to the multimedia device, if there is no multimedia fitting interaction or no multimedia music playing within 30 seconds, it can be considered that the assistive listening function has been fitted with parameters.

[0012] Further, during the use of the assistive listening function, the RSSI technology is used to set the transmission power within a range of two meters, and the Bluetooth radio frequency and the multimedia device are disconnected in a range greater than two meters; and the broadcast scanning frequency interval time is increased within two meters, so that it is in a low-power consumption state, the system and the multimedia device interact and negotiate automatic recognition, and the Bluetooth part in the system will enter a deep sleep state.

[0013] Further, only when an external phone call is made or a phone call is made by oneself, the multimedia state is automatically entered, and when a song is played, the song is played after the phone call is made by the multimedia, and then the song is played, and after 5 seconds, the assistive listening is automatically switched, the song is switched and the sound is adjusted, and the default earphone is used in the multimedia, and is irrelevant to the assistive listening function.

[0014] Further, when there is no external intervention of the earphone physical button or the connected Bluetooth device does not trigger the assistive listening command, the earphone is always in the assistive listening mode.

[0015] On the other hand, the application also discloses a device storing a computer program, which is executed by a processor to make the processor execute the steps of the above method.

[0016] From the above technical solutions can be known, the low-power control method of the Bluetooth auxiliary hearing earphone, mainly aims at the low-power processing method of the Bluetooth auxiliary hearing earphone, mainly according to the fact that the radio frequency power is reduced in the process of the Bluetooth state, the radio frequency power in the range of 2 meters can be adjusted through the RSSI value, the near-distance fitting is realized, the Bluetooth is disconnected in the long-distance, so that the low-power in the Bluetooth state is realized to meet the use, and the Bluetooth function connection of the earphone is in the deep sleep state in the long-time auxiliary hearing function process, that is, the earphone broadcast scanning period is prolonged, and the power consumption of the Bluetooth system in the auxiliary hearing state is basically completely realized.

[0017] Compared with the existing Bluetooth auxiliary hearing: in order to realize the free switching between the earphone in the multimedia state and the auxiliary hearing, the existing Bluetooth auxiliary hearing scheme does not better balance the role of the Bluetooth system in the overall function, so that the diversification of the product function is blindly sought, and the most important power consumption problem is ignored. By using the convenience of Bluetooth fitting, the power consumption of the Bluetooth system is controlled, the auxiliary hearing function is greatly utilized, the manual switching between the multimedia and the auxiliary hearing state is exchanged for the purpose of saving power consumption, and in the switching between the two, the auxiliary hearing is defaulted by the application of the manual switching. The application mainly relates to the closer distance connection and the deep sleep state of the binaural in the Bluetooth function after entering the auxiliary hearing function, and the purpose is to conveniently fit and save power consumption in the whole main function.

[0018] In general, the low-power control method of the Bluetooth auxiliary hearing earphone solves the problem of excessive power consumption of the Bluetooth auxiliary hearing earphone, provides a method for the low-power work of the Bluetooth auxiliary hearing Bluetooth earphone by using the RSSI technology (reducing the Bluetooth radio frequency power) of the Bluetooth, and achieves the purpose of reducing the power consumption during the auxiliary hearing work by using the reasonable broadcast scanning interval, so that the whole machine saves at least about 20% of energy in the auxiliary hearing working state, that is, in the normal auxiliary hearing condition, under the same external condition, the working time is prolonged by at least 2 hours. The overall energy-saving purpose is achieved. After the actual technology is verified and tested, the application fully meets the feasibility, and does not affect the use effect and the operation convenience.

[0019] Compared with the existing Bluetooth technology, the Bluetooth earphone fully utilizes the RSSI technology to realize the problems of wireless communication and rapid connection, and as much as possible increases the transmission power in the use process, so that the master-slave connection of the remote device is realized, and the uninterrupted and high-efficiency information transmission is maintained. The broadcast scanning frequency between the Bluetooth is fixed and must be stable. The auxiliary hearing mainly goes against the Bluetooth earphone here, mainly for saving power consumption and reducing the overall operation of the system. The whole machine power consumption is saved, the standby time of the auxiliary hearing earphone is prolonged, and the application is verified in the actual application. BRIEF DESCRIPTION OF DRAWINGS

[0020] Figure 1Flowchart of methods to reduce power consumption for the entire Bluetooth hearing aid headset. Detailed Implementation

[0021] To make the objectives, technical solutions, and advantages of the embodiments of the present invention clearer, the technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are some embodiments of the present invention, but not all embodiments.

[0022] like Figure 1 As shown in this embodiment, the low-power control method for Bluetooth hearing aids is mainly aimed at addressing the needs of hearing-impaired individuals using new Bluetooth hearing aids. These individuals primarily utilize the auxiliary hearing function, while the fitting function is used less frequently. For an individual, a single fitting typically lasts at least three months before requiring recalibration. Therefore, in most situations, the auxiliary hearing function is used. The usage process includes the following steps:

[0023] S101: After the left and right earbuds are activated, they automatically enter the Bluetooth pairing mode (within ten seconds) to achieve a pair connection. According to the Bluetooth broadcast frequency scanning mode, they connect to the fitting mobile phone and participate in interactive operations (within 30 seconds for quick connection).

[0024] S102: The earphone connects to a multimedia phone, automatically recognizes it, and can be manually put into fitting mode. During this time, the whole device is in Bluetooth mode, and the hearing aid function is also supported to perform wireless Bluetooth fitting.

[0025] S103: After data is implanted via the APP, the auxiliary hearing function is directly activated. Through short broadcast protocol communication between the left and right earbuds, long-interval broadcast scanning communication is achieved for dual-ear connection (with the lowest possible scanning broadcast interval), enabling interconnection between the two earbuds. Furthermore, based on the internal transmission power settings, the main earbud can disconnect from multimedia devices within a range greater than two meters.

[0026] After the earphones are fitted and enter the hearing aid mode, the left and right earphones communicate and negotiate to extend the broadcast scanning interval of the ear connection (which can be indirectly understood as the ear connection being disconnected at this moment).

[0027] The earphone connection is disconnected, and the main earphone is also disconnected from the multimedia system. Bluetooth sweep mode is off, and the system is in Bluetooth's ultra-low power mode. (At this time, power consumption is concentrated on the auxiliary earphone's DSP processing and the entire system core operation).

[0028] Specifically, the specific settings of the embodiments of the present invention are as follows:

[0029] 1. After each use, if there is no multimedia pairing interaction or no multimedia music playback within 30 seconds after the pairing timeout or after reconnecting to the multimedia device, the left and right earbuds can be considered to have entered the auxiliary hearing function with the parameters already matched.

[0030] 2. When the auxiliary hearing function is enabled, RSSI technology can be used to set the transmission power within a two-meter range. Beyond a two-meter range, the Bluetooth radio frequency can be disconnected from the multimedia device. The broadcast scanning frequency interval is increased within two meters to keep it in a low-power state. The system and multimedia device automatically negotiate and identify each other, causing the Bluetooth part running in the system to enter a deep sleep state.

[0031] 3. To avoid frequently switching between multimedia and auxiliary hearing device modes when using multimedia devices.

[0032] Therefore, this invention specifies and sets that the system will automatically enter multimedia mode only when an external phone call comes in or when the user makes a call. When listening to music, the user must enter the multimedia mode on the phone and open the song for simultaneous operation. After closing the mode for 5 seconds, the system will automatically switch to auxiliary listening mode. During this process, the switching of songs and tuning will be performed by default in multimedia mode, which is unrelated to the auxiliary listening function.

[0033] 4. When there is no external interference with the physical buttons on the headphones or when the connected Bluetooth device does not trigger any commands for auxiliary hearing, the headphones will always be in auxiliary hearing mode. This avoids the inconvenience caused to the user by the headphones being switched to the corresponding multimedia operation mode immediately after being connected to a multimedia phone, after powering on, or after touching any function of the phone, or when receiving a message.

[0034] Throughout the entire usage process, it became clear that the Bluetooth hearing aid truly facilitated the fitting process and provided a superior user experience. This energy-saving method, in practical application, significantly reduces power consumption, extends product standby time, decreases the number of headphone charging cycles, increases battery life, and enhances the user experience.

[0035] The main embodiment of this invention reduces power at a certain point and puts the Bluetooth system into deep sleep while it is in operation. This is mainly achieved by adjusting the Bluetooth radio frequency transmission power. For example, when using RSSI for rough positioning, the Bluetooth transmission power only needs to be adjusted to identify multimedia devices within a 2-meter radius. In other words, during normal hearing aid operation, this invention puts the Bluetooth module into deep sleep, with the power consumption of the Bluetooth part being approximately 20uA. Only the DSP in the system processes the external sound pickup function.

[0036] The earphone battery efficiency can be effectively improved, the running time of the main module is beneficially prolonged in the existing multi-module complex system, the main function characteristics of the product are grasped in the overall system design, the power consumption in use is reduced, the running efficiency of the whole machine is improved, and the battery aging is delayed.
