Detailed Description

Specific embodiments of the present disclosure are described in detail below with reference to the accompanying drawings. It should be understood that the detailed description and specific examples, while indicating and illustrating the disclosure, are not intended to limit the disclosure.

In this disclosure, unless otherwise indicated, directional terms such as "inner and outer" are used to refer to both inner and outer of the respective component profiles. Furthermore, when the following description refers to the accompanying drawings, the same numbers in different drawings refer to the same or similar elements unless otherwise indicated.

Referring to fig. 1, the present disclosure provides an earpiece device of an electronic device, including a pinhole sound outlet 110 and an audio module 200. The pinhole type sound outlet 110 may be disposed on the housing 100 of the electronic device, and the audio module 200 may be disposed inside the housing 100 of the electronic device; the audio module 200 may include a sound emitting element 210 and a sound guide channel 220, and both ends of the sound guide channel 220 are connected with the sound emitting element 210 and the pinhole type sound emitting hole 110, respectively, to transmit sound to the outside. Thus, when the earphone device is in operation, the received electrical signal provides the operating voltage for the sound generating element 210 to make the sound, and the sound is transmitted to the pinhole type sound outlet 110 after passing through the sound guiding channel 220 and finally transmitted from the pinhole type sound outlet 110 to the outside to push the outside air to generate the sound. It should be noted that, in the embodiment of the present disclosure, the sound guide channel 220 may also adjust and optimize the sound emitted by the sound generating element 210, so that the sound quality meets the requirements of the earpiece device. For example, the sound guide channel 220 may be configured as a sound guide tube, in which the longer the sound guide tube is, the larger the diameter is, the slower the air column vibration inside the tube body is, the lower the frequency is, whereas the faster the air column vibration is, the higher the frequency is, and the tone is changed when the frequency is changed, so that the sound can be adjusted and optimized.

Through above-mentioned technical scheme, the earphone device of electronic equipment that this disclosure provided has the sound hole of pinhole formula design, and pinhole formula sound hole 110 simple structure, manufacturing are convenient, have significantly reduced the area of sound hole when guaranteeing user's tone quality demand, and its personalized design is pleasing to the eye, fashion, practical, can bring high-tech experience to feel for the user. In addition, the audio module 200 corresponding to the connection with the pinhole type sound outlet 110 may thus have a smaller volume, so that the space occupation of the inside of the case 100 can be effectively reduced.

Further, referring to fig. 2, the pinhole type sound emitting holes 110 may include two spaced apart on the case 100, and accordingly, the audio module may include a low frequency module 201 and a medium frequency module 202 communicating with the two pinhole type sound emitting holes 110, respectively. By arranging two pinhole type sound outlets 110 and connecting the two pinhole type sound outlets with the low-frequency module 201 and the intermediate-frequency module 202, the sound quality restoration effect of the low-frequency and the intermediate-frequency of the receiver device can be better ensured, thereby ensuring the definition and the fidelity effect of the sound quality. The frequency range of the low-frequency module 201 may be 100Hz-1500Hz, and the frequency range of the intermediate-frequency module 202 may be 1500Hz-6000Hz. That is, the low frequency module 201 may receive a voice signal whose frequency points are concentrated in the range of 100Hz-1500Hz, and the intermediate frequency module 202 may receive a voice signal whose frequency points are concentrated in the range of 1500Hz-6000Hz.

In the embodiment provided in the present disclosure, the pinhole type sound emitting hole 110 may have a diameter of 0.6mm to 1.0mm, for example, the pinhole type sound emitting hole 110 may preferably have a diameter of 0.8mm. Of course, those skilled in the art may also reasonably design and select the diameter of the pinhole type sound emitting hole 110 according to actual needs, which is not limited in this disclosure. In this way, compared to the conventional earphone sound outlet, the pinhole sound outlet 110 of the earphone device provided by the present disclosure has a smaller structural size, and the selective arrangement space on the housing 100 is wider, which does not affect other structures and can save manufacturing cost. More prominently, the earphone device can meet the hearing requirement of the user only through the at least one pinhole type sound outlet 110, so that the earphone device has stronger practical performance.

According to some embodiments, referring to fig. 1 to 3, the sound generating element 210 may be a moving iron sound generating unit, and the sound guide channel 220 may be correspondingly configured as a sound guide tube, so that the sound generated by the moving iron sound generating unit is transmitted to the pinhole sound generating hole 110 through the sound guide tube and then transmitted to the outside. Although the sound emitted by the moving iron sound generating unit can be transmitted in a small-hole pipeline mode (namely, the pinhole sound generating design is met), the sound quality of the moving iron sound generating unit cannot meet the sound quality requirement of the earphone device, so that the sound guiding pipe can be connected to the sound outlet end of the moving iron sound generating unit, besides the sound can be transmitted, the sound quality of the sound emitted by the moving iron sound generating unit can be regulated, namely, the sound emitted by the moving iron sound generating unit is transmitted to the outside after being optimally regulated by the sound guiding pipe, and the sound quality requirement of the earphone device can be met. Wherein the sound guide tube may be configured in a circular shape, and the material may be preferably a resin material.

It should be noted that the sound guide tube may have a size adapted to the actual requirement. Wherein, the voice frequency band is usually between 450Hz-4.5KHz, the wavelength is between 76mm-760mm, and the voice frequency band belongs to the middle and high frequency bands. Through the length with leading the sound pipe with reference to high frequency sound wave and low frequency sound wave reasonable arrangement, can make high frequency voice signal bump refraction with the pipe wall in the inside transmission process of body in order to offset the attenuation, and low frequency voice signal vibration is slower, the wavelength is longer, therefore the relative refraction is less can not produce the attenuation to owing to have longer air column in the body, can promote low frequency effect correspondingly. In addition, the smaller the diameter of the sound guide tube, the more the sound of the high-frequency component is, the more the sound is, and the sound of the low-frequency sound wave is relatively blocked and cannot be emitted, so that the diameter of the sound guide tube is reasonably selected. In the disclosed embodiment, the selection of the size of the sound guide tube may also be designed in combination with the characteristics of the pinhole type sound emitting aperture 110 and the moving iron sound emitting unit.

Further, referring to fig. 2, the low frequency module 201 may include a low frequency moving iron sounding unit 211 and a low frequency sound guide pipe 221, and the intermediate frequency module 202 may include an intermediate frequency moving iron sounding unit 212 and an intermediate frequency sound guide pipe 222, so that the voice signal concentrated in the low frequency band may be transmitted to the outside through the low frequency module 201, and the voice signal concentrated in the intermediate frequency band may be correspondingly transmitted to the outside through the intermediate frequency module 202. The length of the low-frequency sound guide tube 221 is greater than that of the medium-frequency sound guide tube 222, so that the low-frequency sound guide tube and the medium-frequency sound guide tube respectively exhibit corresponding low-medium-frequency effects. For example, the length of the low frequency sound guide 221 may be 140mm-185mm, preferably 165mm; the length of the intermediate frequency sound guide 222 may be 40mm-65mm, preferably 50mm.

Further, referring to fig. 3, the moving iron sound generating unit may include a sound outlet nozzle 213, one end of the sound guide tube may be correspondingly connected to the sound outlet nozzle 213, and the other end may be connected to the pinhole type sound outlet 110. The sound guide tube may be fixedly connected to the sound outlet 213 by bonding or the like.

In addition, as shown in fig. 3, the moving iron sound emitting unit may be constructed in a rectangular shape, and a shock pad 213 may be provided to wrap thereon. The shock pad 213 may not be provided at a position of the moving iron sound generating unit where the sound outlet 213 is provided, so as to avoid interference with the sound outlet 213. The shock pad 230 can avoid vibration of the housing 100 and other electronic components inside the housing 100 caused by the operation of the moving iron sound generating unit, thereby avoiding the problems of sound leakage and noise caused by vibration of the housing 100, and reducing the damage probability of the electronic components caused by frequent vibration. In an embodiment in which the earpiece device is applied to an electronic apparatus such as a mobile phone, the shock pad 230 can also prevent the abnormal vibration feeling of the mobile phone case from being generated when the mobile phone case contacts the hand, the ear, and the face due to vibration during a user's conversation, and enhance the user's feeling of using the body. Among them, the shock pad 230 may be preferably manufactured of a butyl rubber material, which may have a square structure matched with that of the moving iron sound emitting unit.

It should be noted that the structure of the sound generating element 210 is not limited in this disclosure, for example, the sound generating element 210 may be a moving coil speaker in addition to the moving iron sound generating unit. The moving iron sounding unit and the moving coil loudspeaker are electroacoustic elements, and can generate vibration sounding along with an input electric signal, and the electric signal can generate vibration in different states along with the change of the vibration state of the electric signal so as to generate different sounds. The moving iron sound generating unit and the moving coil loudspeaker can be preferably of a medium-low frequency and high sensitivity type. In other embodiments, the sound generating element 210 may be configured in a piezoelectric type, an electromagnetic type, or the like, and the sound guiding channel 220 may be adapted to the sound generating element 210.

In the embodiment provided in the present disclosure, referring to fig. 1, the sound emitting element 210 and the sound guide channel 220 may be arranged inside the case 100 in a straight line, i.e., the moving iron sound emitting unit and the sound guide tube may be sequentially arranged inside the case 100 and both are located on the same straight line. The arrangement not only can save the internal space of the shell 100, but also can reduce the resistance of the sound in the outward transmission process as much as possible, reduce the sound transmission path and ensure better tone quality effect.

To avoid sound leakage when transmitted through the sound guide channel 220 and to allow for aesthetic reasons of the earpiece device, the end of the sound guide channel 220 may abut against the inner end surface of the pinhole type sound outlet 110. For example, the end of the sound guide tube can be abutted and fixed on the inner end surface of the pin hole type sound outlet 110, so that a gap between the sound guide tube and the shell 100 can be avoided.

Further, the inner diameter of the sound guide tube may be the same as the diameter of the pinhole type sound outlet 110, for example, the inner diameter of the sound guide tube may be preferably 0.8mm, and the sound guide tube may be radially aligned with the pinhole type sound outlet 110, so that sound can be smoothly transmitted to the outside through a transmission channel without inflection points, sound attenuation is reduced, and the requirements of earphone tone quality are met to the greatest extent.

In addition, referring to fig. 3, in order to prevent the end of the sound guide channel 220 connected to the pinhole type sound output hole 110 from being affected by external dust and liquid (e.g., water, oil), the end of the sound guide channel 220 connected to the pinhole type sound output hole 110 may be sequentially installed with a waterproof and breathable film 300 and a dust screen 400, i.e., the dust screen 400 may be installed at the outer side of the waterproof and breathable film 300, so as to effectively prevent water and dust.

Fig. 4 to 7 show audio curves obtained by testing with different configurations of the earpiece device, respectively. Wherein, the earphone device that adopts in fig. 4 includes two moves indisputable sound production unit, two sound guide pipes that are connected with moving indisputable sound production unit respectively and the shock pad of parcel on moving indisputable sound production unit respectively (can be for the above-mentioned earphone device that this disclosure provided), the earphone device that adopts in fig. 5 includes one moves indisputable sound production unit and the sound guide pipe that is connected with this moving indisputable sound production unit, the earphone device that adopts in fig. 6 includes one moves indisputable sound production unit and the shock pad of parcel on this moving indisputable sound production unit, the earphone device that adopts in fig. 7 only includes one and moves indisputable sound production unit. In fig. 4 to 7, if the reference value is located between the upper limit and the lower limit, the reference value is an ideal audio curve, and a sound with good quality can be played; if the reference value exceeds the upper limit or is lower than the lower limit, the non-ideal audio curve is generated, the generated sound has flaws, and the curve, which is closer to the area between the upper limit and the lower limit, in the non-ideal audio curve is less in flaws, and conversely, the flaws are more. As is apparent from fig. 4 to 7, the audio curves obtained by testing the earphone device provided by the present disclosure are substantially all located between the upper limit and the lower limit, so that relatively high-quality sound can be played, and the sound quality of the relatively high-quality sound can meet the requirements of the earphone device.

Referring to fig. 8, the present disclosure further provides an electronic device, including an earpiece device, where the earpiece device may be an earpiece device of the electronic device, and the housing 100 may be a shell of the electronic device correspondingly. The electronic device has all the beneficial effects of the above-mentioned earphone device, and will not be described here again.

According to other embodiments, referring to fig. 8, the electronic device may further include a display 20, the housing 100 may have a frame surrounding the display 20, and the pinhole type sound emitting holes 110 may be correspondingly disposed on the frame, so that reserving sound emitting holes on the display 20 may be avoided, and the occupied area of the display 20 is reduced, which is beneficial to realizing full-screen.

For example, in an embodiment in which the electronic device is a mobile phone, the pinhole type sound outlet 110 may be disposed on a frame on the top of the mobile phone, so that the earpiece sound is emitted from the top of the mobile phone, thereby meeting the working requirement of the earpiece of the mobile phone when the user is talking. The mobile phone receiver device provided by the invention can enable the mobile phone receiver to be moved away from the front screen of the mobile phone, and is beneficial to the development process of the full-screen mobile phone. The "top" is defined according to the normal use state of the mobile phone, and specifically, reference may be made to the direction of the drawing shown in fig. 8. It should be noted that, the display 20 not only refers to a mobile phone panel portion with a display effect, but also includes a whole front panel portion of the mobile phone, and by moving the sound emitting hole away from the front panel of the mobile phone, more display area with a display effect can be provided for the front panel, so as to meet the continuous expansion requirement of the display area of the user.

In addition, when the earphone device provided by the present disclosure is applied to an electronic device such as a mobile phone, when the earphone device is installed, the sound generating element 210 can be stuck and fixed on the middle frame plate inside the mobile phone, then one end of the sound guiding channel 220 is connected with the sound outlet end of the sound generating element 210, and the other end is fixedly connected with the pinhole sound outlet 110, so that the installation process is simple and easy to operate, and the production cost is further saved.
