Example 1

According to an embodiment of the present application, there is provided a microphone apparatus. Fig. 1 is a schematic diagram of a microphone arrangement according to an embodiment of the present application. As shown in fig. 1, the microphone device 10 may include: a first connector 12, and a first resistor 14 connected in series between a microphone port 122 of the first connector 12 and a ground port 124 of the first connector 12.

The first connector 12 is used for connecting with an electronic device; the first resistor 14 is used to be recognized as a microphone by the electronic device after the first connector 12 is connected to the electronic device.

The first connector may be a connector commonly used at present, and the connector has a function of outputting an audio signal, i.e. a microphone, for example, the first connector may be a 3.5mm TRRS connector, a Type-C connector, or a Lightning connector. In order to make the microphone apparatus have functions of an earphone and a microphone, the first connector includes four ports, which are a left channel port, a right channel port, a ground port and a microphone port, and the arrangement order of the four ports is different according to different standards, which is not specifically limited in the present application. In order to simulate a false microphone, a first resistor with a suitable resistance may be connected in series between the microphone port and the ground port of the first connector 12, so that the electronic device may recognize the microphone apparatus as a microphone, and optionally, the first resistor may be a resistor with a target resistance selected from a plurality of preset resistors with different resistance values, and the target resistance may be around 2k Ω, for example, in the embodiment of the present application, the target resistance may be 2.4k Ω, but is not limited thereto.

The microphone device can be inserted into an electronic device through the first connector, where the electronic device can be a PC, a notebook computer, a smart phone, a tablet computer, and the like. After the first connector is connected with the electronic equipment, the electronic equipment needs to detect the microphone device, determine whether the earphone and the microphone are inserted, and if the earphone and the microphone are determined to be inserted, an operating system or a sound card chip of the electronic equipment shields the speaker and the microphone of the electronic equipment, outputs audio through the inserted earphone and inputs audio through the inserted microphone. Since the microphone device is loaded with no signal, the sound collected by the electronic device is blank.

In a conference use scenario, a PC or a notebook computer is used in most cases, and therefore, a TRRS connector is described as an example in the embodiment of the present application. Therefore, the microphone arrangement as a whole can be regarded as a TRRS joint with a small tail. In this scenario, if connection with an electronic device provided with an interface of another Type is required, optionally, the microphone device may be connected to the electronic device through an interface conversion line, for example, for an Android mobile phone with a Type-C interface, the microphone device may be connected to the Type-C conversion line, and the Type-C interface on the Type-C conversion line is inserted into the Android mobile phone; for the IPhone of the Lightning interface, the microphone device may be connected to the Lightning conversion line, and the Lightning interface on the Lightning conversion line may be plugged into the IPhone.

Through the scheme provided by the above embodiment of the application, the microphone device may be composed of the first connector and the first resistor connected in series between the microphone port and the ground port of the first connector, and after the microphone device is connected with the electronic device, the microphone device may be identified as a microphone by the electronic device, so as to achieve the purpose of physically shielding the microphone carried by the electronic device. It is noted easily that, whole microphone device simple structure, the cost is lower, need not to send the interference audio frequency through the ultrasonic wave, avoids the user to expose for a long time in the ultrasonic wave environment, reaches and reduces the anti-eavesdropping cost, improves the anti-eavesdropping effect, promotes the technological effect that user experience felt, and then has solved the higher and relatively poor technical problem of effect of cost of anti-eavesdropping scheme among the correlation technique.

In the above embodiment of the present application, the microphone apparatus further includes: and the second resistor is connected between the left channel port and the grounding port of the first connector in series and is used for being identified as the earphone by the electronic equipment after the first connector is connected with the electronic equipment.

For some electronic devices, it is first necessary to detect whether a headset is inserted and then to detect whether a microphone is inserted. Therefore, in order to expand the application range of the microphone device and ensure that the microphone device can be identified as a microphone by the electronic equipment in different application scenes, a second resistor with proper resistance value can be connected in series between the left channel port and the grounding port of the first connector, so that the electronic equipment can identify the microphone device as an earphone. The resistance value of the second resistor may be between 50 Ω and 200 Ω, for example, in the embodiment of the present application, the resistance value of the second resistor may be 100 Ω, but is not limited thereto.

In the above embodiments of the present application, the microphone apparatus further includes: and the third resistor is connected between the right channel port and the ground port of the first connector in series.

In an alternative embodiment, a third resistor with a suitable resistance value may be connected in series between the right channel port and the ground port of the first connector, and the resistance value of the third resistor may be between 50 Ω and 200 Ω, for example, in this embodiment, the resistance value of the third resistor may be 100 Ω, but is not limited thereto.

When a user needs to hold a confidential conference, the TRRS connector can be inserted into a computer used by the user, so that an operating system or a sound card chip of the computer can automatically identify the microphone device as a microphone, and automatically switch the microphone on the computer into a pseudo microphone simulated by the microphone device, so that trojans and third-party software on the computer can only monitor blank sounds, and can only hear blank sounds after misdialing/answering, thereby achieving the purpose of eavesdropping prevention.

In the above embodiments of the present application, the microphone apparatus further includes: and two input ends of the TRS socket are respectively connected with the left channel port of the first connector and the right channel port of the first connector, and the TRS socket is used for outputting the audio signal input by the first connector to the earphone after the earphone is inserted.

In a scene that a user participates in a teleconference or remote learning, the user often needs to hear sound in a computer, so that in order to expand the use range of the microphone device and facilitate use requirements of different users, the left sound channel port and the right sound channel port of the first connector can be led out to be connected with the TRS socket, when the user needs to hear the sound in the computer, the earphone can be inserted into the TRS socket, the computer identifies the earphone inserted by the user, transmits the sound in the computer to the TRS socket through the first connector, and further transmits the sound in the computer to the earphone through the TRS socket.

In the above-described embodiments of the present application, in the case where the first connector is a TRRS connector, the microphone device is connected to the electronic apparatus through the interface conversion line.

In most anti-eavesdrop scenes, often need prevent that PC or notebook computer from being monitored, and adopt the TRRS interface on PC or the notebook computer usually, consequently, can directly adopt TRRS to connect and constitute the microphone device, when scenes such as android mobile phone, IPhone, IPAD need be used to the user, TRRS connects and can't satisfy above-mentioned demand, can directly connect through Type-C crossover sub or Lightning crossover sub.

In an optional embodiment, in order to meet the requirement of a user using an electronic device such as an android phone, an IPhone, and an IPAD for eavesdropping prevention, and avoid the user not preparing an interface conversion line, which may result in the failure of the purpose of eavesdropping prevention, a second connector (such as a Type-C connector or a Lightning connector) may be disposed in the microphone apparatus, and the second connector may be used as a connector connected to the electronic device. Therefore, the microphone device as a whole is a Type-C connector or Lightning connector with a tail.

In the above embodiments of the present application, the first joint includes: in the case of the conversion chip, the first resistor is connected to the conversion chip.

The existing Type-C connector or lighting connector is often provided with an ADC (Analog to Digital Converter) chip, in an alternative embodiment, in order to further reduce the volume of the microphone device, the Type-C connector or lighting connector may be used as the first connector, and the first resistor may be connected to the ADC chip (i.e. the above-mentioned conversion chip) in the connector, so that after the microphone device is connected to the electronic device, the microphone device can be identified by the electronic device as the microphone by setting the ADC chip to the operating state in which the microphone is connected. Therefore, the microphone device as a whole is a Type-C connector or Lightning connector with a small tail.
