A part of the invention can be applied to computer program product, such as computer program instructions, when it is calculatedWhen machine executes, by the operation of the computer, it can call or provide according to the method for the present invention and/or technical solution.And it adjustsIt with the program instruction of method of the invention, is possibly stored in fixed or moveable recording medium, and/or passes through broadcastOr data flow in other signal-bearing mediums and transmitted, and/or be stored in and set according to the computer of program instruction operationIn standby working storage.Here, according to one embodiment of present invention including one as shown in Fig. 2, Fig. 3, Fig. 8 and Fig. 6 AEquipment, which includes the memory module 11 or computer program memory medium 300 for storing computer program instructionsWith the calibration module 14 for executing program instructions, wherein when the computer program instructions are executed by the processor, triggering shouldEquipment is executed based on the method and/or technology scheme in aforesaid plurality of embodiment.
It should be noted that the present invention can be carried out in the assembly of software and/or software and hardware, for example, can adoptWith specific integrated circuit (ASIC), general purpose computer or any other realized similar to hardware device.In one embodimentIn, software program of the invention can be executed by processor to realize above step or function.Similarly, software of the inventionProgram (including relevant data structure) can be stored in computer readable recording medium, for example, RAM memory, magnetic orCD-ROM driver or floppy disc and similar devices.In addition, some of the steps or functions of the present invention may be implemented in hardware, for example,As the circuit cooperated with processor thereby executing each step or function.
In conclusion headphone calibration structure of the invention includes earphone and auricle space；And the earphone includes storageModule, audio playing module, audio collection module and calibration module, when carrying out the calibration of earphone, calibration module sends controlThe audio file that signal processed is stored to audio playing module, audio playing module broadcasting memory module；And it is set to auricle skyBetween audio collection module acquisition audio playing module play the audio signal of the audio file, calibration module is then receiving instituteAfter stating audio signal, the audio signal and the audio file are compared, and audio is corrected according to comparing result and is playedThe frequency response parameter of module, so that the frequency response parameter of audio playing module and the frequency response parameter of standard audio file are consistent, toolThe frequency response parameter for making audio playing module of body coincides with preset ideal frequency response curve.Wherein, auricle space includes human earThe test space of auricle space or prefabricated human ear auricle structure.Thereby take into account the difference in the human ear auricle space of each human bodyIt is different, preferably earphone after a period of use, using headphone calibration structure carry out earphone calibration, realize the ear under producing lineThe calibration of machine.Due to being preferably in the auricle that earphone is worn on user, it is possible thereby to well adapt to ear in calibrationMachine is calibrated under specific application environment.Also, provide accordingly for headphone calibration structure earphone and calibration method,Computer program memory medium improves user to the usage experience of earphone.
Certainly, the present invention can also have other various embodiments, without deviating from the spirit and substance of the present invention, ripeIt knows those skilled in the art and makes various corresponding changes and modifications, but these corresponding changes and change in accordance with the present inventionShape all should fall within the scope of protection of the appended claims of the present invention.
