Description

Earphone, earphone control method and system

Technical Field

The invention relates to the field of data processing, in particular to an earphone, and an earphone control method and system.

Background

Fig. 1 is an exploded view of a headphone according to an embodiment of the present invention, and fig. 2 is a sectional structure view of the headphone according to the embodiment in a see-through mode, the headphone including:

a first housing 100 including a sound guide 110 provided with a sound outlet hole 111;

a second housing 200, wherein the second housing 200 is connected with the first housing 100 to form a housing, and a sound channel 900 is arranged on the housing;

a sound generating unit 300 accommodated in the housing, wherein the sound generating unit 300 divides the housing into a front sound cavity formed by the sound generating unit 300 and the housing on one side of the sound guide 110, and a rear sound cavity formed by the sound generating unit 300 and the other side of the housing; a driving component 400, configured to drive the sound generating unit 300 to be located in a first position range far away from the sound guide 110 or to be located in a second position range close to the sound guide 110;

when the sound generating unit 300 is in the first position range, the sound channel 900 is communicated with the front sound cavity;

when the sound generating unit 300 is in the second position range, the sound channel 900 is not communicated with the front sound cavity.

It should be noted that the sound cavity inside the earphone can be regarded as being formed by an inner cavity of the earphone shell, the sound generating unit divides the sound cavity into a front sound cavity and a rear sound cavity, one side of the sound generating unit, which generates sound, is the front sound cavity, and the other side of the sound generating unit is the rear sound cavity. The first position range and the second position range are both position ranges, that is, are not one position point, so that the positions of the sound generating units 300, in which the sound channel 900 is communicated with the front sound cavity, all belong to the first position range, and similarly, the positions of the sound generating units 300, in which the sound channel 900 is not communicated with the front sound cavity, all belong to the second position range.

The earphone of the present invention has the driving assembly 400 connected to the sound generating unit 300 in the casing, the sound channel 900 communicated with the outside in the casing, and the position of the sound generating unit 300 adjustable by the driving assembly, so as to adjust the communication state between the front sound cavity of the earphone and the outside. Specifically, when external sound needs to be heard, the sound production unit 300 is controlled to move to the first position range, at this time, the sound channel 900 is communicated with the front sound cavity, the mode is defined as a transparent mode, in the mode, a user can directly hear the external sound through the sound outlet hole 111 or the auricle sound collection under the condition that the earphone is not taken down, the transparent effect is achieved, the external sound is not required to be received through the microphone, the lossless external sound is directly received, and the external real sound is reserved. When the media audio or the voice call needs to be heard, the other mode is used, that is, the sound generating unit 300 is controlled to move to the second position range, at this time, the sound channel 900 is not communicated with the front sound cavity, and the sound generating hole 111 is the sound generated by the sound generating unit. The earphone of the invention realizes the switching between the through mode and other modes through the adjustment of the positions of the sound channel 900 and the sound generating unit 300.

Different settings of the earphone on the volumes of the front sound cavity and the rear sound cavity can influence the presence of sound and the performance of each frequency band in audio, and generally, the smaller the volume of the front sound cavity is, the more the middle and high frequencies extend to the high frequency band; the larger the back volume, the more the low frequency cut-off frequency extends toward the low frequency band. Further, in an embodiment of the present invention, the second position range may include a voice position range and a musical tone position range; the distance between the voice position range and the sound guide 110 is greater than the distance between the musical sound position range and the sound guide 110.

When the sounding unit 300 is in the musical tone position range, the volume of the front sound cavity is small, the reduction of the volume of the front sound cavity can effectively improve the frequency response sound pressure of the high-frequency band, the frequency response band extends to high frequency, and the sound quality has better spatial sense; the volume reduction of the front sound cavity means the volume increase of the back sound cavity at the same time, the volume increase of the back sound cavity can effectively improve the low-frequency-band frequency response, at the moment, the bass is more powerful, the low-frequency-band sound-frequency-.

When the earphone is in a voice call, it is desirable that the sound pressure of the high frequency band is decreased and the frequency response of the low frequency band is decreased to reduce the interference of the low frequency noise and the high frequency noise under the voice call, thereby reducing the influence of the environmental sound and the noise on the call quality, at this time, the volume of the front sound cavity needs to be increased.

In order to further improve the low-frequency band frequency response and improve the bass dynamics, in the embodiment, when the sound generating unit 300 is located in the voice position range, the sound channel 900 is closed, and at this time, the sound channel 900 is not communicated with the front sound cavity or the rear sound cavity of the earphone, as shown in fig. 3, a cross-sectional structure diagram of the earphone according to an embodiment of the present invention when the earphone is located in the voice mode; however, when the sound emission unit 300 is in the range of musical tone positions, the sound channel 900 is in communication with the rear cavity, which is in communication with the outside, as shown in fig. 4, which is a sectional view of the earphone according to an embodiment of the present invention in the musical tone mode. The volume of the back sound cavity is increased compared with the volume of the back sound cavity, and the back sound cavity is communicated with the outside to play a role in improving the frequency response of a low frequency band and improving the bass dynamics.

Likewise, the voice position range and the tone position range are both position ranges, not one position point, and the position of the sound emitting unit 300 such that the sound channel 900 is closed belongs to the voice position range, and the position of the sound emitting unit 300 such that the sound channel 900 communicates with the rear sound chamber belongs to the tone position range.

The earphone of the present invention realizes the conversion between the voice mode and the music mode by the sounding unit 300 being far away from or close to the sound guide 110, and can simultaneously satisfy different requirements for the tone quality when listening to the media audio and when talking.

In this embodiment, the first position range, the voice position range, and the tone position range are sequentially adjacent to the sound guide 110, and the earphone is switched among the pass-through mode, the voice mode, and the tone mode by the adjustment of the sound channel 900 and the sound emitting unit 300 at the above positions. The earphone of this embodiment may specifically include:

the earphone may further include an earphone cover 500, wherein the earphone cover 500 is connected to the sound guide 110, and the sound guide 110 is connected to the second housing 200. The earphone cap 500 and the sound guide 110 may be connected by fastening; the sound guide element 110 and the second housing 200 may also be connected by fastening; the connection mode between the earphone lid and the sound guide member, and between the sound guide member and the second housing is not limited to the above fastening mode.

The second housing 200 may specifically include a second housing cover 210 and a cover plate 220, and the second housing 200 may also be a single piece. The sound channel 900 is disposed at a connection between the second casing 200 and the first casing 100, in this embodiment, the connection is specifically a connection between the sound guide 110 of the first casing 100 and the second casing 200.

The sound passage 900 may be a perforated slit at the junction of the first and second housings, and the provision of the sound passage 900 at the junction of the second housing 200 and the first housing 100 is advantageous in terms of convenience in manufacturing process. Since the volumes of the front sound cavity and the rear sound cavity directly affect the auditory effect of the sound emitted by the sound generating unit transmitted to the ears of the user through the sound emitting holes, the adjustable volume ranges of the front sound cavity and the rear sound cavity can be controlled by setting the sizes of the first shell 100 and the second shell 200. Of course, the sound channel 900 may also be a perforated slit disposed at other positions of the earphone housing, such as on the second housing 200, see fig. 1, and the size of the perforated slit may be set according to the sound quality effect. The set sound channel 900 plays different roles due to the change of the position of the sound generating unit 300, and when the sound channel 900 is communicated with the front sound cavity, it plays a role of a sound transmitting hole, and when it is communicated with the rear sound cavity, it plays a role of a low sound hole. The sound channel changes the effect because of the dislocation of sound producing unit, has promoted earphone convenience and multiple use.

The driving component is not limited, and can be contained in the shell of the earphone and can drive the sound production unit to move at the position far away from and close to the sound guide piece.

In some embodiments, the drive assembly 400 employs a voice coil motor, particularly a linear voice coil motor. A Voice Coil Motor (Voice Coil activator/Voice Coil Motor) is a device that converts electrical energy into mechanical energy. The voice coil motor utilizes the interaction between the magnetic field from the permanent magnet steel and the magnetic poles in the magnetic field generated by the electrified coil conductor to generate regular motion, the positioning precision of the voice coil motor depends on a feedback and control system, the high-frequency response and high-precision moving positioning can be realized, and the voice coil motor has the characteristic of long service life.

As shown in fig. 1 to 4, the voice coil motor may include a base 410, a motor body 420 connected to the base 410, and a moving voice coil 430 connected to the motor body 420, wherein the moving voice coil 430 abuts against the sound unit 300. The base 410 of the voice coil motor may be fixed to the cover plate 220 of the second housing 200, the sound generating unit 300 may abut against the voice coil motor, and the movement of the voice coil 430 of the voice coil motor along the axis (OO') may control the sound generating unit 300 to approach or separate from the sound guide 110. In practical use, the sound generating unit 300 is not limited to a type, and may be a moving coil speaker, a ceramic speaker, or a balanced armature speaker. The outer ring of the sounding unit 300 may also be covered with a Polytetrafluoroethylene (PTFE) O-ring having a self-lubricating airtight effect, so as to ensure that when the position of the sounding unit 300 in the cavity of the earphone housing is changed, the sound quality is changed accordingly due to the change of the volumes of the front sound cavity and the rear sound cavity.

The earphone can be a wireless earphone or a wired earphone. When the earphone is a wireless earphone, in order to receive a signal for adjusting the moving position of the sound generating unit through the earphone itself, in other embodiments, the earphone may further include a touch sensing element for receiving a touch signal for adjusting the position of the sound generating unit 300.

The existing wireless earphone adopts a double-microphone design, external sound is introduced into an ear canal through an external microphone and an amplifier, so that a wearer can hear environmental sound, the power consumption of a battery is increased, and external sound distortion exists. Compared with the existing wireless earphone, the earphone of the invention effectively changes the response of the earphone to sound frequency by adjusting the position of the sound production unit, thereby saving the power consumption of the earphone battery; meanwhile, the transparent mode does not need the consumption of the electric quantity of the battery of the earphone, so that the electric power consumption of the battery of the earphone is smaller, and the service life of the battery is longer.

The earphone of the invention not only can influence the presence of sound and the performance of each frequency band in audio frequency by setting the volumes of the front sound cavity and the rear sound cavity, but also can be provided with the sound release hole, the sound guide tube sponge, the sound guide tube tuning paper and the like, and if the front sound cavity is provided with the sound release hole, in terms of auditory perception, if the leakage quantity is more, the components for isolating external noise are less, namely, the external sound is easier to hear; the back sound cavity can be provided with a miniature loudspeaker vent hole, a ventilation tuning mesh cloth and the like, and the details are not repeated.

Some embodiments of the present invention further provide an earphone control method, configured to control the earphone, and fig. 5 is a flowchart of the earphone control method according to an embodiment of the present invention, specifically, the earphone control method includes the following steps:

s100: judging whether a trigger signal is received or not;

if the trigger signal is received, S110: judging the type of the trigger signal;

if the trigger signal is a first type signal, S111: the driving component drives the sound production unit to be in a first position range, namely the earphone is in a through mode;

if the trigger signal is the second type signal, S112: the driving component drives the sound production unit to be in the second position range.

The touch signal may be a touch signal received by a terminal in communication with an earphone, and the terminal may include any electronic device used by a user and capable of communicating with the earphone, and may be a mobile phone, a tablet computer, a Personal Digital Assistant (PDA), a Digital photo frame, a media player, a watch device, a pendant device, an earphone or earphone device, a navigation device, a wearable or micro device, and the like, and the type is not limited.

In some embodiments, a touch sensing component may be disposed on the headset, and the trigger signal may be received through the touch sensing component. For example, the touch signal may be formed by a touch operation on a touch sensitive surface of the touch sensing assembly. The touch operation refers to an operation in which a user body part (hand, elbow, etc.) or a touch pad directly contacts a touch-sensitive surface, such as a single-click, double-click, or triple-click touch screen.

The first type of signal for enabling the sound generating unit to be in the first position range, that is, the earphone to be in the transparent mode, may be set as a touch operation, such as a single-click touch screen, and similarly, the other touch operation may be set as a second type of signal, such as a double-click touch screen, which is not described herein again.

Fig. 6 is a flowchart of an earphone control method according to still another embodiment of the present invention, the second position range including a voice position range and a musical tone position range;

the method further comprises the steps of:

if the trigger signal is not received, S120: judging whether an audio signal is received or not;

if an audio signal is received, S130: judging the type of the audio signal;

if the audio signal is a voice call type, S131: the driving component drives the sound production unit to be in the voice position range;

if the audio signal is of a musical tone type, S132: the drive component drives the sound generating unit to be in the musical tone position range.

If the audio signal is not received, the driving component does not drive, and the sound production unit is in the original position state.

When the earphone of the present invention is a wireless earphone, the audio transmission model protocol of the wireless earphone includes: HSP (HeadsetPro-file), HFP (HandProfile), A2DP (Advanced Audio Distribution Profile) and AVRCP (Audio Video Remote control core Profile). At this time, the step S130 may determine the type of the audio signal according to the type of the protocol for transmitting the audio signal. If HSP and HFP transmit telephone audio, the audio signal is considered to be of the voice call type, and A2DP and AVRCP transmit media audio, the audio signal is considered to be of the musical tone type.

When the earphone control method is applied to an actual scene, the system monitors in real time and judges whether a trigger signal is received, if so, S110 to S111 are executed, or S110 to S112 are executed; if not, execute steps S120 to S131, or execute steps S120 to S132.

Of course, the earphone control method may be that when the system performs steps S120 to S131 or performs steps S120 to S132, if the system monitors in real time and determines that a trigger signal state is received, the system triggers step S111 or step S112. In the above method, the trigger signal is used as the control signal of the priority. The priority between the trigger signal and the system signal can also be set or modified by the system, which is not limited by the present invention.

Some embodiments of the present invention further provide an earphone control system, which is used in the earphone control method, and fig. 7 is a schematic structural diagram of the earphone control system according to an embodiment of the present invention, where the earphone control system includes a control module M100 and a driving module M200;

the control module M100 is configured to determine whether a trigger signal is received and determine a type of the trigger signal;

the driving module M200 is configured to send an instruction to the driving component, so that the driving component drives the sound generating unit to be in the first position range or the second position range, and of course, the earphone control system may include a sound module M300 configured to output sound to an earphone, and a signal receiving module M400 configured to receive a trigger signal.

The function implementation manner of each functional module in the earphone control system of the embodiment can be implemented by adopting the specific implementation manner of each step in the earphone control method. For example, the control module M100 and the driving module M200 may respectively adopt the above-mentioned specific embodiments to implement their functions, which are not described herein again.

In summary, the earphone of the present invention is provided with the driving component connected to the sound generating unit in the casing, the sound channel communicated with the outside is provided on the casing, and the position of the sound generating unit can be adjusted by the driving component, so as to adjust the communication state between the front sound cavity of the earphone and the outside, and thus, the earphone can be switched between the transparent mode and the other modes.

Meanwhile, the earphone can also adjust the volume of the front sound cavity and the volume of the rear sound cavity by adjusting the position of the sounding unit, so that the earphone can be switched among a transparent mode, a voice mode and a music mode. When the earphone is in a musical tone mode, the volume of the front sound cavity is reduced, so that the frequency response sound pressure of a high-frequency band can be effectively improved, the frequency response frequency band extends to high frequency, and the sound quality has better spatial impression; meanwhile, the volume of the back sound cavity is increased and is communicated with the outside, so that the low-frequency band frequency response is effectively improved, and the bass is more powerful. When the earphone is in a voice mode, the volume of the front sound cavity is increased, the sound pressure of a high-frequency band is reduced, the frequency response of the low-frequency band is reduced, the low-frequency noise (such as wind cutting sound) and the interference of the high-frequency noise under voice communication are reduced, and the influence of environmental sound and noise on the communication quality is reduced; meanwhile, the volume of the front sound cavity is increased to improve the frequency response of the middle frequency band, which is beneficial to the definition of voice in a voice communication state, namely, the earphone of the invention can simultaneously meet different requirements on the tone quality when listening to media audio and communicating.

The earphone of the invention effectively changes the response of the earphone to sound frequency by adjusting the position of the sound production unit, thereby saving the power consumption of the battery of the earphone; meanwhile, the transparent mode does not need the consumption of the electric quantity of the battery of the earphone, so that the electric power consumption of the battery of the earphone is smaller, and the service life of the battery is longer.

The foregoing is a more detailed description of the invention in connection with specific preferred embodiments and it is not intended that the invention be limited to these specific details. For those skilled in the art to which the invention pertains, several simple deductions or substitutions can be made without departing from the spirit of the invention, and all shall be considered as belonging to the protection scope of the invention.
