In order to ensure better sound effect and wearing comfort, the headset basically adopts leather materials such as PU, PVC or genuine leather to manufacture the earmuffs.
Leather materials such as PU, PVC, genuine leather and the like are rich in lipid substances, and provide rich substrates for the growth of mould. In order to achieve a good softness, it is also possible to add to these substrates agents which increase the softness, and if the environment is relatively humid during packaging or use, the leather material becomes mouldy. Moreover, once the earphone is affected with damp, the sound of the earphone is smaller than before, the bonding pad in the earphone is also corroded to cause the resistance of the earphone to become larger, and even the conditions of partial sound and dull sound occur, and in addition, the earphone is affected greatly by damp, so that the service life of the earphone is prolonged. The same may occur in other styles of headphones.
In order to prevent the earphone from getting damp and mildewing, in the prior art, a drying agent and a mildewproof sheet are usually placed in a packaging box of the earphone to avoid high humidity, so as to prevent the growth of mildews, or a user is recommended to use mildewproof antibacterial paste to wipe an earmuff or other leather parts, so that the earphone has mildewproof capability. However, when the leather material is actually sold or used, the merchants and users cannot know the actual humidity or water content of the leather material, and cannot perform mildew-proof dehumidification treatment in time. In addition, the earphones are packaged when being shipped out of a factory, and if the earphones become mildewed due to damp and hot environment in the transportation process, sellers do not know the earphones, and complaints of users are easily caused.

One skilled in the art will appreciate that the embodiments described herein can be combined with other embodiments.
Fig. 1 is a block diagram illustrating a structure of an embodiment of the earphone receiving device 1 according to the present invention. In the present embodiment, the earphone storing device 1 is used to store a headphone and detect the water content of an ear cup 3 of the headphone and a filling material such as sponge in the ear cup 3. Typically, the ear muffs 3 are arranged outside the earphone house 2 and a filling substance is arranged between the ear muffs 3 and the earphone house 2. It should be noted that, in this embodiment, the earphone is a headphone as an example, and those skilled in the art can clearly understand that, after the shape of the housing of the earphone receiving device 1 is adjusted, the earphone receiving device 1 can also be used for receiving other types of earphones, such as a headphone for hanging ears and the like.
As shown in fig. 1, the earphone accommodation device 1 includes a housing. A sensing element 10 is provided in the housing. The sensing element 10 is in contact with the outer surface of the ear cup 3 to determine the detection area of the outer surface of the ear cup 3. In the present embodiment, the sensing element is a humidity sensor, and an alternative structure of the humidity sensor includes a substrate made of a lithium chloride humidity-sensitive substrate and a metal electrode coated with a humidity-sensitive film made of an electrolyte solution. The humidity sensitive element is disposed in the housing. When the headset is placed in the headset storing device 1, the humidity sensitive element may be embedded in the ear cup 3, or be located outside the ear cup 3 in contact with the outer surface of the ear cup 3, or be located on the underside of the ear cup 3 in contact with the outer surface of the ear cup 3, or grip the outer surface of the ear cup 3 to form a detection area 31 on the surface of the ear cup.
Also provided in the housing is a detection module 20, which detection module 20, after determining a detection area 31 of the outer surface of the ear cup 3, is arranged to apply a detection signal in the form of a voltage over the sensing element 10, i.e. the humidity sensitive element, and to measure a resistance parameter of the humidity sensitive element. Depending on the electrical characteristics of the humidity sensor, the resistance parameter of the humidity sensor will change as the humidity in the detection area 31 changes. Thus, based on this physical characteristic, the processing module 30 disposed in the housing may further generate the moisture content of the detection area 31 from the resistance parameter of the moisture sensitive element. The processing module 30 is preferably designed around a separate MCU. In this embodiment, the sensing element 10, the detecting module 20 and the processing module 30 can also be integrated into one MEMS humidity sensing chip.
In addition to the humidity sensitive element, as another alternative embodiment, the sensing element 10 may include at least one pair of electrodes disposed at a distance. The number of electrodes can be chosen according to the area of the ear cup 3, and the plurality of electrodes can be arranged in any suitable array so as to cover different areas of the ear cup 3. The electrode can be made of a metal conductor, can also be made of new materials such as conductive fibers, conductive rubber, conductive paint and the like, and can also be in the form of a patch electrode. The electrodes are arranged in the housing and when the headset is placed in the headset receiving device 1, one or more of the electrodes may be embedded in the ear cups 3, or be located outside the ear cups 3 in contact with the outer surface of the ear cups 3, or be located on the underside of the ear cups 3 in contact with the outer surface of the ear cups 3, or clamp the outer surface of the ear cups 3 to form a detection area 31 located between the electrodes.
A detection module 20 is also provided in the housing, which detection module 20 is adapted to apply a detection signal on the sensing element 10 and to measure an impedance parameter of the detection area 31, after determining the detection area 31 of the outer surface of the ear cup 3. The detection module 20 may adopt different circuit forms, for example, a current excitation form and a voltage sampling form, specifically, one electrode is connected with an excitation source as an input electrode, the other electrode is connected with a voltage detection circuit as an output electrode, so as to form a detection loop, and the detection module 20 obtains the impedance parameter of the detection area 31 by applying a detection signal in the form of a current to one electrode and measuring the voltage between the input electrode and the output electrode. It is also possible to use forms of voltage excitation and current sampling, in particular where one electrode is connected to an excitation source as an input electrode and the other electrode is connected to a current detection circuit as an output electrode, so that the impedance parameter of the detection area 31 is measured by applying a detection signal in the form of a voltage to one electrode and measuring the current at the output electrode. For materials common for making the ear muffs 3, such as leather, sponge, etc., there is a property that the impedance is smaller with increasing moisture therein, so that, based on this physical property, the processing module 30 arranged in the housing can further generate the moisture content of the detection area 31 from the impedance parameter. The processing module 30 is preferably designed around a separate MCU.
As a preferred embodiment, as shown in the schematic diagram of fig. 8, a first fitting correction equation generated from the set water content and the detected resistance value, or a second fitting correction equation generated from the set water content and the detected resistance value, or both fitting correction equations are stored in the processing module 30. The first fitting correction equation and the second fitting correction equation are obtained in an experimental environment. Specifically, in the case where the water content is known, earmuffs 3 having different water contents are respectively put into the earphone storing device 1 for testing. When the humidity sensitive element is used as the sensing element, when the ear muffs 3 with different humidity are in full contact with the humidity sensitive element, the detection module 20 applies a voltage detection signal to the humidity sensitive element and obtains a resistance detection value of the humidity sensitive element in contact with a detection area, so that a plurality of detection data in one-to-one correspondence with the water content and the resistance detection value, namely a group of discrete points, are obtained, and the obtained one or more groups of discrete detection data are further fitted to obtain a first fitting correction equation between the resistance detection value and the set water content. After the earphone to be tested is placed in the earphone receiving device 1, the detection module 20 can obtain the resistance parameter of the humidity sensitive element contacting with the detection area. The processing module 30 inputs the resistance parameter into the corresponding fitting correction equation to obtain the water content corresponding to the current resistance parameter.
Similarly, when electrodes arranged at intervals are used as the sensing elements, when the ear cups 3 having different set water contents are in sufficient contact with the sensing elements 10, the detection module 20 applies detection signals to the sensing elements 10, such as the electrodes 11-1 and 11-2 shown in fig. 8, and obtains impedance detection values of the detection areas. So as to obtain a plurality of detection data with one-to-one correspondence of the water content and the impedance detection value, namely a group of discrete points; of course, multiple sets of experiments can be repeated to obtain multiple sets of discrete detection data. And further fitting the obtained one or more groups of discrete detection data to obtain a second fitting correction equation of the impedance detection value and the water content. After the earphone to be tested is placed in the earphone storage device 1, the detection module 20 can obtain the impedance parameters of the detection area, and the processing module 30 inputs the impedance parameters into the second fitting correction equation to obtain the water content corresponding to the current impedance parameters. The generation of the first fitting correction equation and the second fitting correction equation can be realized by a predetermined algorithm in existing software, such as Matlab, etc., and is not further limited herein.
The disclosed earphone storage device of above-mentioned embodiment can play the effect of accomodating the earphone on the one hand, and on the other hand also can carry out real-time detection to the earphone when needing, especially the water content of ear muff part to be convenient for seller or consumer know the production, storage, transportation, the user state of earphone in real time, when water content is on the high side in the ear muff, can in time improve environmental parameter or service condition, avoid the earphone to appear mouldy or because the problem that wets and tone quality descends.

In practice, the first sensing element 101 and the second sensing element 102 may also comprise a greater number of pairs of electrodes and be arranged in any suitable array formation.
