Abstract
The invention relates to a microphone with a unique identification code. The microphone comprises a microphone body which is used for acquiring sound signals; a storage unit which is used for storing the unique identification code of the microphone; a control unit which is connected with output of the microphone body and the storage unit and used for controlling output of the unique identification code of the microphone according to the input signal or the working state of the microphone body. The microphone is enabled to output the unique identification code of the microphone in an audio format in working and information of the model number and batch of the microphone is provided, and acquisition of the information does not need to use special devices like image identification or laser scanning so that information management and maintenance of the microphone product are facilitated.
Description
Technical field
The present invention relates to microphone field, in particular to a kind of microphone with unique identifier.
Background technology
Current, microphone is widely used in each class of electronic devices, the year shipment amount of whole world microphone has broken through 1,000,000,000, be the producer, developer or regulator all need a kind of method to a large amount of different model, batch microphone carry out effective information management and tracking.The mode generally adopted at present prints numbering to identify microphone information in microphone chip encapsulation.This method needs human eye identification, or obtains microphone information by special image recognition and Laser Scanning Equipment, the former inefficiency, and the latter has then limited to use scenes and increased cost and the difficulty of obtaining information.
Summary of the invention
The invention provides a kind of microphone with unique identifier, make microphone operationally can export its unique identifier with audio format, provide microphone model, batch etc. information, be convenient to information management and the maintenance of microphone products.
Technical problem solved by the invention realizes by the following technical solutions:
With a microphone for unique identifier, comprising: a microphone main body, for collected sound signal; One memory cell, for preserving the unique identifier of microphone; One control unit, is connected with the output of memory cell with microphone main body, for whether exporting unique identifier according to the input signal of microphone main body or working state control microphone.
Preferably, described unique identifier can use digital signal or analog signal to represent.
Preferably, described unique identifier exports with audio format, and this audio format can be through modulation or unmodulated.
Preferably, described microphone main body adopts the analog/digital microphone based on MEMS, or electret analog/digital microphone.
Preferably, described control unit controls according to the input signal of described microphone main body the switching mechanism whether described memory cell exports described unique identifier.
The invention has the beneficial effects as follows, make microphone operationally can export its unique identifier with audio format, there is provided microphone model, batch etc. information, the acquisition of information does not need by the Special Equipment such as image recognition or laser scanning, is convenient to information management and the maintenance of microphone products.
Accompanying drawing explanation
Fig. 1 is system configuration schematic diagram of the present invention;
Fig. 2 is the structural representation of a specific embodiment of the present invention.
Embodiment
The invention provides a kind of microphone with unique identifier, make microphone operationally can export its unique identifier with audio format, there is provided microphone model, batch etc. information, the acquisition of information does not need by the Special Equipment such as image recognition or laser scanning, is convenient to information management and the maintenance of microphone products.
Below in conjunction with the drawings and specific embodiments, the invention will be further described, but not as limiting to the invention.
In FIG, the microphone of unique identifier is with to comprise microphone main body 1, for collected sound signal; Memory cell 2, for preserving the unique identifier of microphone; Control unit 3, is connected with the output of microphone main body 1 with memory cell 2, whether exports unique identifier for controlling microphone.
Unique identifier in memory cell 2, is write when microphone dispatches from the factory by the producer.After microphone powers on, microphone main body 1 starts collected sound signal, and control unit selects whether export described unique identifier according to the input signal of microphone or operating state.
Wherein, above-mentioned unique identifier can use digital signal or analog signal to represent; Above-mentioned unique identifier can export by audio format, and this audio format can be through modulation or unmodulated.
Wherein, microphone main body can adopt the analog/digital microphone based on MEMS, or electret analog/digital microphone.
In the embodiment of fig. 2, the unique identifier of digital microphone is expressed as 0xABCDEF with 24bit PCM form, judge whether to export unique identifier according to the input signal 301 of microphone and operating state 302, wherein control unit 3 can control a kind of switching mechanism according to input signal 301, can the outgoing route of permanent disconnection memory cell 2, this switching mechanism includes but not limited to fuse.If user considers not wish to expose unique identifier for business security, secret protection etc., 301 signals can be driven with high level, permanently disconnect the outgoing route of memory cell 2, hide unique identifier information; If user's choice for use unique identifier function, input signal 301 is kept to be low: when input signal 302 is for high, microphone is with the normal sound collection result of PCM formatted output; When input signal 302 is low, microphone is with its unique identifier of PCM formatted output.
The above description of this invention is illustrative, and nonrestrictive, and those skilled in the art is understood, and can carry out many amendments, change or equivalence, but they all will fall within the scope of protection of the present invention within the spirit and scope of claim restriction to it.
