For example, some operations / steps can be decomposed, and some operations / steps can be combined or partially combined, so the actual execution order may change according to actual conditions.

[0027] The block diagrams shown in the accompanying drawings are merely functional entities and do not necessarily correspond to physically independent entities. That is, these functional entities may be implemented in software form, or in one or more hardware modules or integrated circuits, or in different networks and / or processor devices and / or microcontroller devices.

[0028] The term "and / or" or "and / or" includes all combinations of any one or more of the associated listed items.

[0029] like Figure 1 As shown, the connection method of the existing hearing aid debugging system consists of three parts: a USB or RS232 serial port connection cable, a programmer with a USB or RS232 serial port (such as Hipro / Noah-link), and a programming cable.

[0030] like Figure 2 and Figure 3 As shown, the present specification provides a hearing aid programming cable with interchangeable line sequences, including: a PS2 interface, a line sequence switching switch, and a programming cable; the PS2 interface is connected to the line sequence switching switch, and the line sequence switching switch switches the line sequence of the hearing aid programming cable. The programming cable is used to connect to the hearing aid programming interface. Compared with the existing hearing aid debugging system, it omits a variety of data programming cables with different line sequences, making the device easier to carry, and is connected and debugged through a programming cable with a line sequence switching switch in conjunction with a programmer.

[0031] The line sequence switching switch includes at least two micro switches, and the switching of at least two different line sequences is realized by controlling the on and off states of the micro switches. A micro switch is a small electrical switch, which usually has a small size and light weight, but can withstand a certain current and voltage.

[0032] The micro switch includes a mechanical dip switch; each mechanical dip switch is provided with at least two dip positions, and the on-off state of the mechanical dip switch can be switched by manually toggling the dip switch to different positions. The design of the mechanical dip switch makes it have good durability and stability. Due to its relatively simple structure, it is not easily affected by the external environment, so it can maintain stable performance under various harsh working conditions. In addition, the on-off state switching speed of the dip switch is fast and the response is sensitive, which can meet the needs of most application scenarios.

[0033] Micro switches control the on-off state through mechanical structures and / or electronic switches, so that users can manually and / or automatically switch the line sequence. In terms of mechanical structure, micro switches usually use precise mechanical devices to switch the on-off state. For example, through mechanical parts such as operating rods, knobs or dials, users can manually change the contact state inside the switch to control the on and off of the circuit. This mechanical control method is simple and intuitive, and is suitable for occasions that require frequent adjustments or manual intervention. At the same time, with the continuous development of electronic technology, electronic switches have gradually become an important part of micro switches. Electronic switches control the on-off state through electronic components (such as transistors, integrated circuits, etc.), which can achieve faster and more accurate switching operations. In addition, electronic switches can also be combined with intelligent devices such as sensors and microprocessors to realize automatic line sequence switching functions. In practical applications, micro switches can choose manual or automatic control methods according to specific needs. For example, in some occasions that require fast response or high reliability, electronic switches can be used to achieve automatic switching; while in some occasions that require manual adjustment or maintenance, mechanical control methods can be used. In addition, complex control logic can be designed to combine manual and automatic switching methods to meet more flexible and diverse application requirements.

[0034] Line sequence switching is done by a double-pole double-throw switch. The design of the double-pole double-throw switch gives it a unique switching function. It contains two independent knives (i.e. contacts) and two throws (i.e. positions or states). Each knives can be switched between the two throws, thereby changing its connection state. This design allows the double-pole double-throw switch to control two different sets of circuits or lines, realizing more complex switching logic. In the application of line sequence switching, the double-pole double-throw switch realizes the connection and disconnection between different lines by controlling the switching state of its internal knives. Specifically, when the switch is in a certain throw position, one set of knives may connect a certain line, while another set of knives disconnects another line; when the switch is switched to another throw position, the original connection state will change, realizing the switching of the line sequence. The advantage of this switching method lies in its flexibility and reliability. Since the double-pole double-throw switch has two independent switching paths, it can control the connection state of multiple lines at the same time, thereby realizing more complex line sequence switching requirements. In addition, due to the precise design of its internal mechanical structure, the double-pole double-throw switch usually has lower contact resistance and higher stability during the switching process, ensuring the accuracy and reliability of the switching. In practical applications, double-pole double-throw switches are widely used in various occasions that require line sequence switching. For example, in communication systems, it can be used to switch different signal lines to achieve flexible signal transmission; in power management systems, it can be used to switch different power lines to ensure stable operation of equipment; in automation control systems, it can be used to implement complex control logic and line switching.

[0035] Hearing aids are hearing aids developed based on I2C or SPI communication chips. The digital signal of the programmer is transmitted to the line sequence switch through the programming line for line sequence conversion. After the line sequence conversion of the digital signal at the line sequence switch, it is transmitted to the hearing aid chip of the hearing aid processing unit through the programming line. The biggest difference between it and mainstream hearing aid products is that only one programming line can be used for communication, and there is no need for multiple programming lines of different standards. According to the configuration of the existing PC in the market, there are two connection methods: one is to directly connect to the serial port for programming; the other is to program through USB to serial port (considering that many computer motherboards now do not have serial ports).

[0036] Take programming via USB to serial port as an example. The hearing aid includes a hearing aid chip, a microphone, a receiver, and a battery compartment (power supply part). The hearing aid chip is a mainstream chip on the market that supports I2C or SPI communication. The host computer includes a PC, a mobile phone, and a PAD.

[0037] Working principle: The hearing aid transmits the digital signal of the programmer to the line sequence switch in the programming line through the PS2 interface. After the line sequence is converted, the signal is then transmitted to the hearing aid DSP chip in the hearing aid processing unit through the hearing aid programming line.

[0038] The present invention only provides the implementation principle and does not specifically describe the parameters of various components, because they can be selected in actual production and are well known to those skilled in the art. The structure of the data programming line is as follows:

[0039] like Figure 4 As shown, the PS2 interface includes a PS2 male socket connected to the PS2 female socket on the hearing aid programmer, which has built-in SCL data bus and SDA data bus for transmission and communication via the I2C protocol.

[0040] like Figure 5 As shown in the figure, the function of the line sequence switch is to convert the communication line sequence. Because there are many hearing aid and hearing aid programmer manufacturers, each hearing aid and hearing aid programmer manufacturer has its own set of standards, which leads to differences in the line sequence of hearing aid programming cables. In this way, it is necessary to equip hearing aid programming cables with multiple different line sequences during the fitting process. The line sequence switch can be used to switch the line sequence.

[0041] like Figure 6 As shown, the hearing aid programming line provides power and communication interface to the DSP.

[0042] The hearing aid programming cable with exchangeable line sequence provided by the utility model solves the problems in the prior art that the programming cable has a fixed line sequence, is easy to be confused, and is easy to damage the hearing aid.
