Description
Technical Field
The present application relates to the field of electronics, and in particular, to a circuit and an electronic device for identifying an electronic accessory.
Background
An Audio jack Connector (Audio jack Connector) is a pair of connection units consisting of a plug and a socket that can be plugged and unplugged. Audio connectors are commonly used to connect two audio devices of different functions or effects together, each of which features its own. For example, a media player of a mobile phone is connected to an earphone through an audio connector, and the media player transmits an electrical signal of music to the earphone through the audio connector; the headset then converts the electrical signals into audible sound waves using a speaker proximate to the ear.
An audio connector is a commonly used electronic accessory, which has two modes of operation: a closed mode of operation and an open mode of operation. Currently, the two modes of operation are not universal. I.e. the jack of an audio connector can only use one mode of operation.
In reality, in the production process, the audio connector socket used as an electronic product accessory is not easy to control the supplied materials, so that a dedicated circuit board needs to be designed and produced for the audio connector of each working mode, thereby improving the manufacturing cost of the electronic product. If the electronic product adopts an audio connector socket with one working mode, the inventory shortage of the audio connector socket often occurs, thereby causing the problem of production stoppage.

The present application provides a circuit for identifying an electronic accessory; the application also provides an electronic device. Details are described in the following examples one by one.
A first embodiment, an embodiment of a circuit for identifying an electronic accessory, is provided.
This embodiment is described in detail below with reference to fig. 1, where fig. 1 is a schematic circuit diagram of an audio jack in a closed operating mode according to an embodiment of the present application; fig. 2 is a schematic circuit diagram of an audio jack in an open operating mode according to an embodiment of the present application; fig. 3 is a schematic structural diagram of a circuit for identifying an electronic accessory according to an embodiment of the present disclosure; FIG. 4 is a schematic structural diagram of a circuit for identifying an electronic accessory according to an embodiment of the present disclosure; fig. 5 is a schematic circuit diagram of an audio jack for identifying a closed operating mode according to an embodiment of the present application.
An audio connector is a commonly used electronic accessory, which has two modes of operation: a closed mode of operation and an open mode of operation. Currently, the two modes of operation are not universal. I.e. the jack of an audio connector can only use one mode of operation.
Referring to fig. 1, when the audio jack in the closed operating mode is not plugged into an audio plug, the feature pin 11 and the auxiliary pin 12 are connected together, and the feature pin 11 outputs a low level outwards; when the audio plug is inserted, the feature pin 11 is separated from the auxiliary pin 12, and the feature pin 11 outputs a high level to the outside.
Referring to fig. 2, when the audio jack in the open mode of operation is not plugged into an audio plug, the feature pin 13 is separated from the auxiliary pin 14, and the feature pin 13 outputs a high level; when the audio plug is inserted, the feature pin 13 is connected to the auxiliary pin 14, and the feature pin 13 outputs a low level to the outside.
The purpose of this embodiment is to design a circuit that recognizes the audio jack mode of operation and can accommodate the audio jack mode of operation.
Referring to fig. 3 and 4, a circuit for identifying an electronic accessory in the present embodiment includes: an electronic accessory 1 and an identification module 2.
And the electronic accessory 1 is electrically connected with the identification module 2 through a characteristic pin and used for outputting the characteristic information of the electronic accessory to the identification module 2 through the characteristic pin.
The characteristic pin is the characteristic pin 11 of the closed operation mode audio socket or the characteristic pin 13 of the open operation mode audio socket.
The electronic accessory includes a plurality of characteristic information. For example, the feature information of the feature pin of the audio jack is a high level and a low level.
For the audio socket in the closed working mode, the characteristic information of the electronic accessory 1, namely when the audio socket is not plugged into an audio plug, the characteristic pin 11 and the auxiliary pin 12 are connected together, and the characteristic information output by the characteristic pin 11 is low level; when the audio plug is inserted, the feature pin 11 is separated from the auxiliary pin 12, and feature information output to the outside by the feature pin 11 is at a high level.
For the audio jack in the open working mode, the characteristic information of the electronic accessory 1, namely when the audio jack is not plugged into an audio plug, the characteristic pin 13 is separated from the auxiliary pin 14, and the characteristic information output outwards by the characteristic pin 13 is in a high level; when the audio plug is inserted, the feature pin 13 is connected to the auxiliary pin 14, and feature information output to the outside by the feature pin 13 is at a low level.
The electronic component 1 in this embodiment is used for outputting recognizable feature information to the recognition module 2 under the same condition, so that the recognition module 2 can clearly recognize the working mode of the electronic component 1. For example, when the circuit is first powered up and an audio jack is not plugged in; under the condition, the feature information output outwards from the feature pin of the audio socket is used as the discrimination data; for the audio socket in the closed working mode, the characteristic information output outwards by the characteristic pin 11 of the audio socket is in a low level; for the audio jack in the open operating mode, the feature information output from the feature pin 13 of the audio jack is low.
And the identification module 2 is used for acquiring the characteristic information transmitted by the electronic accessory 1 when the circuit is in a preset working state, identifying the characteristic information and storing an identification result.
For example, if the circuit is in a preset operating state, when the circuit is powered on for the first time and the audio jack is not plugged, that is, when the intelligent electronic device operates for the first time in a basic input output system (BIOS for short), the circuit is in a preset operating state. In this case, everything in the circuit is in an initial state, and all information on this basis is in a pre-designed state, that is, all information is known, so that interference with other information can be eliminated.
The identification module 2 comprises: an identification unit 21 and a storage unit 22.
The identification unit 21 is configured to, when the circuit is in a preset operating state, acquire feature information transmitted by the electronic component 1, identify the feature information according to a preset condition, acquire type information of the electronic component 1 matching the feature information, and transmit the type information of the electronic component 1 to the storage unit 22.
The type information of the electronic accessory 1 is often expressed in a computer using simple letters or numbers. For example, the types of audio jacks include: an audio jack in a closed operating mode and an audio jack in an open operating mode; the type information of the audio jack may indicate the audio jack in the closed operation mode by "1" and indicate the audio jack in the open operation mode by "0".
The preset condition is the relationship between the feature information and the type information of the electronic accessory 1. For example, continuing with the above example, when the circuit is in the preset operating state, the preset conditions are: the low level indicates information output from the audio jack in the closed operating mode, and corresponds to the type information "1", and similarly, the high level corresponds to the type information "0".
And identifying the characteristic information according to a preset condition, and acquiring the type information of the electronic accessory 1 matched with the characteristic information. For example, continuing the above example, the low level output from the audio jack in the closed operation mode to the identification unit obtains that the type information of the audio jack in the circuit is "1" according to the correspondence of the preset condition.
A storage unit 22, configured to acquire the type information of the electronic accessory 1 transmitted by the identification unit 21, and store the type information of the electronic accessory 1.
The storage unit 22 includes an operation subunit 221 and a memory 222.
An operation subunit 221, electrically connected to the identification unit 21, for acquiring the type information of the electronic accessory 1 transmitted by the identification unit 21 and storing the type information of the electronic accessory 1 in a memory 222.
Preferably, the memory 222 is a read-only memory.
Read-Only Memory (ROM), in which data stored in ROM is usually written in advance before being loaded into the whole machine, and can Only be Read out during the operation of the whole machine, unlike the ram, which can be rewritten quickly and conveniently. The data stored in the ROM is stable, and the stored data can not be changed after power failure; the structure is simple, the reading is convenient, and therefore the method is commonly used for storing various fixed programs and data. But typically ROM can be written with data by BIOS when the intelligent electronic device is first powered up.
Further, since the ROM is different from a general memory, writing data to the ROM is also distinctive, and a device having a burning function must be used to write data to the ROM. The operation subunit 221 is configured to implement a function of burning the rom.
When the intelligent electronic device including the circuit is powered on again, the BIOS may directly obtain initialization information for the electronic accessory 1 associated with the type information of the electronic accessory 1 stored in the ROM by the type information of the electronic accessory 1 stored in the ROM.
In order to prevent the change of the characteristic information output by the characteristic pin of the electronic accessory 1, which causes the error of the information stored in the ROM, the circuit further comprises a switching module 3. Please refer to fig. 4.
The switching module 3 is connected with the electronic component 1 and the identification module 2, and is used for disconnecting the electrical connection between the characteristic pin of the electronic component and the identification module after the identification module 2 acquires the characteristic information transmitted by the electronic component 1 when the circuit is in a preset working state.
The following description will be given taking as an example a circuit for identifying an audio jack in a closed operating mode. Please refer to fig. 5.
In this embodiment, the circuit is powered on for the first time, and when the audio jack in the closed operating mode is not plugged, that is, the circuit operates in the BIOS stage of the intelligent electronic device. The feature pin 11 of the closed operating mode audio jack outputs feature information, i.e. a low level, to the identification module 2, when the feature pin 11 is connected to ground.
The GPIO1 interface 23 of the identification module 2 receives the characteristic information. The recognition module 2 recognizes the feature information and acquires type information of the audio jack in the closed operation mode (assuming the type information of the audio jack, the audio jack in the closed operation mode is represented by "1", and the audio jack in the open operation mode is represented by "0"). Furthermore, the type information is burned into the ROM through a burning device. When the intelligent electronic device is powered on again, the BIOS directly obtains the type information through the GPIO2 interface 24 of the identification module 2, and further obtains initialization information for the audio jack in the closed operating mode, which is associated with the type information, and initializes the audio jack in the closed operating mode. This allows easy handling steps.
In this embodiment, when the circuit is powered on for the first time, inserting an audio plug will cause the feature pin 11 of the closed operating mode audio jack to output a high level to the identification module 2. Thereby affecting the result of the saving in the ROM. Therefore, the PMOS transistor 31, the first NMOS transistor 32 and the second NMOS transistor 33 in fig. 5 constitute the cut flower module 3. When the circuit is powered on for the first time and the feature pin of the closed operation mode audio socket outputs a low level, the PMOS transistor 31 and the first NMOS transistor 32 will be short-circuited, and therefore, the output of the feature pin 11 of the closed operation mode audio socket cannot affect the input of the GPIO1 interface 23. Thereby ensuring the correctness of the result stored in the ROM.
The closed working mode audio socket is changed into an open working mode audio socket, and the circuit is also suitable. This is not repeated again.
The embodiment increases the application selectivity of the electronic accessory, enables the same circuit to be suitable for multiple working modes of the electronic accessory, avoids designing and producing a special circuit board for the electronic accessory of each working mode in production, and reduces the manufacturing cost of electronic products. Meanwhile, the problem of production stagnation caused by shortage of electronic accessories is avoided for users, and the production efficiency is improved.
With the second embodiment provided in the present application, namely, an embodiment of an electronic device, is as follows:
the embodiments of the electronic device provided in the present application are described relatively simply, and for related parts, reference may be made to the corresponding description of the embodiments of the circuit for identifying an electronic accessory provided above.

Further, the circuit for identifying the electronic accessory is provided in the housing of the apparatus main body.
