Description

[Technical field of the invention]

The present invention relates to a method for providing services using a noise-shielding ear hook, namely a system and a method for providing the application services, wherein application services such as interpreting, Writing the meeting minutes and messenger are offered

[Technical background of the invention]

Recently, with the development of wireless communication technology, various wireless communication services are being offered. While short-distance wireless communication technology as well as mobile communication technology are being developed, the basis is being established for wireless devices and terminals to provide various wireless communication services from the be able to offer simple message transmission through to the provision of multimedia services.

In particular, active research is being carried out on the development of short-distance wireless communication technology which is connected to a huge network through wireless communication with peripheral devices. The wireless near-field communication includes WLAN, Bluetooth, infrared communication (IrDA), ZigBee and UWB (Ultra-WideBand). Among them, Bluetooth which consumes relatively little power is widespread, and technologies for transmitting with a large capacity and minimizing power consumption are continuously being researched.

Therefore, many ear hooks equipped with a Bluetooth module have recently come onto the market. Various functions such as sound output, telephone call and control of the connection terminal can be carried out in the relevant ear hook.

At the same time, a wired or wireless method can be used for the connection between a left earphone and a right earphone, and recently a wireless earhook in which the left earphone and the right earphone are wirelessly connected has come on the market. This is also known as a TWS (True Wireless Stereo) wireless ear hook.

As described above, when the left earphone and the right earphone are connected by wireless communication, since each earphone can be used independently, various services can be provided. That is, the left earphone is worn by the first user and the right earphone is worn by the second user, so that various services such as listening to music together or interpreting between the parties, etc., can be offered.

In addition, in order to use various services such as interpreting, etc., a microphone is installed inside the ear hook, and since the speaker's voice is picked up by the microphone, there is a limit to using an interpreting service in places with strong outside noise.

Therefore, a speech recognition rate needs to be improved in an ear hook that includes a microphone. That is, there is a need for a way to improve the speech recognition rate even in places where there is a lot of outside noise.

Then the structure and the problems of an ear hook are briefly described here.

An ear hook is typically seen as an in-ear earphone, which is a sound device through which a sound is heard as it is pushed into the auricle and the external auditory canal.

Since the ear hook is pushed into the external auditory canal, there is a difference in air pressure between the inside (human body pressure) and the outside (atmospheric pressure) of the ear hook. That is, since an ear cushion cap formed on the ear hook is in close contact with the inner wall of the external auditory canal, an air pressure difference occurs between the inside and the outside of the ear hook. However, this air pressure difference affects the diaphragm of the speaker driver unit, and there occurs a phenomenon that the diaphragm inclines toward the outside of the ear hook. With this phenomenon, there arises a problem that not only does sound output become difficult, but the sound also becomes distorted.

Accordingly, in order to prevent the diaphragm from being tilted, a back hole is formed at the end of the rear of the speaker drive unit. Since the rear hole formed at the end of the rear side of the speaker driver unit connects through the through hole formed in the case, a function is performed to provide the same air pressure between the inside and outside of the ear hook maintains. As a result, the diaphragm can be vibrated in the correct position. The loudspeaker driver unit can be roughly divided into a dynamic driver unit and a balanced armature driver unit.

In the meantime, the membrane can be artificially adjusted so that different air pressure differences are generated when the membrane is in operation. One of the methods is to cover the back hole with dampers that have the different densities of mesh. Using this method, the speaker driver unit is also tuned.

However, the rear hole formed at the end of the rear of the speaker drive unit has a problem that functions as a path through which the outside noise is conducted. However, if the rear hole formed at the end of the rear side of the speaker driving unit is closed, the above-described diaphragm inclination occurs and so it cannot be used in an airplane or in a high mountain area. At the same time, when the rear hole of the speaker driver unit is closed, the vibration of the diaphragm is suppressed, and there arises a problem that the sound is distorted.

There is also a need for a method of improving the quality of the sound from the loudspeaker and speaker's voice by shielding the inflow of outside noise through the rear hole formed at the end of the rear of the loudspeaker driver unit.

1 Figure 13 is a block diagram of a system for providing the application services using a noise shielding earhook in accordance with an embodiment of the present invention.

Indicating 1 A system for providing the application services of the present invention using a noise shielding earhook comprises the following parts: a wireless earhook 100 , which therefore contains the following parts; a left earbud 110 , which in turn consists of a left speaker driver unit 111 , a left microphone 112 and a left wireless communication module 113 and a right earbud 120 , that is, from a right speaker driver unit 121 , a right microphone 122 and a right wireless communication module 123 consists; and a smartphone 200 , in which a service corresponding to the application is provided, with a sound signal and a voice signal each for the left earphone 110 and the right earbud 120 processes and controls.

This includes the smartphone 200 the following parts: a near-field wireless communication module 210 , in which a wireless communication each with the left wireless communication modules 113 and the right wireless communication module 123 is performed, and a control part 220 of the ear hook, which is configured in such a way that a transmission / reception control of the wireless ear hook 100 executed in response to a user setting or a voice signal.

According to the invention configured in this way, a communication processing system of the wireless ear hook provides the role of a master or a slave for the left earphone 110 and the right earbud 120 with a control part 220 of the ear hook on (real-time switching). For example, by clicking on an icon that can be accessed via an app on the smartphone 200 is displayed, the master or slave role of the wireless ear hook 100 can be switched in real time. Furthermore, an ear hook, in which the voice input takes place through speech recognition, etc., can be automatically set to the master ear hook.

For example, such as in a case where a communication processing system of the wireless ear hook of the present invention is applied to an interpreting service, a left earphone 110 in Korean and a right earbud 120 are set to English (for voice input), if Korean voice input is used, the left earbud can 110 set as the master earbud and the right earbud 120 can be set as slave earphones. Accordingly, in the smartphone 200 the voice input from the left earbud 110 translated into English and played on the right earbud 120 transfer. If English is spoken during this time, the right earbud will 120 as the master earbud and the left earbud 110 set as slave earphones. In the same way, in the smartphone 200 the voice input from the right earbud 120 translated into Korean and played on the left earbud 110 transfer. In this case, real-time switching to the master earphone or to the slave earphone can be made via an app on the smartphone 200 or by speech recognition. In addition, a language can be determined by the language analysis of each counterpart and an adjustment to the master or the slave can be carried out automatically.

In the present embodiment it is shown that a wireless ear hook 100 to a smartphone 200 is paired, however, two or more wireless earhooks can be used 100 be linked to the smartphone. Therefore, in the smartphone 200 a receiving module (not shown in drawings) in which a near field communication module is connected to at least two or more wireless earhooks 100 coupled, can be provided, and various near field communication modules can be provided.

2 Figure 13 is a block diagram of a system for providing the application services using a noise shielding earhook in accordance with another embodiment of the present invention.

Indicating 2 In the application service providing system of the present invention, at least one user terminal is connected to a network using a noise shielding ear hook, and the network may be a mobile communication network or a near field communication network.

Here, a user terminal, in which a service corresponding to the application is provided, processes and controls the wireless ear hook 100 and a sound signal and a voice signal for the wireless ear hook, respectively 100 , and it contains a smartphone connected to the network 200 .

As in 1 shown includes a wireless ear hook 100 the following parts: a left earbud 110 that consists of a left speaker driver unit 111 , a left microphone 112 and a left wireless communication module 113 and a right earbud 120 that consists of a right speaker-driver unit 121 , a right microphone 122 and a right wireless communication module 123 consists.

The smartphone 200 can selectively a mobile communication module connected to the mobile communication network 230 and a near field communication module 210 , in which a wireless communication in each case with the left wireless communication module 113 and the right wireless communication module 123 is carried out.

At the same time, as in 1 shown the smartphone 200 a control part 220 of the wireless ear hook, which have a transmission / reception control of the wireless ear hook 100 in response to a user setting or a voice signal.

According to the invention configured in this way, in the communication processing system of the wireless ear hook, each user terminal connected to a mobile communication network or a near-field wireless communication network can perform services such as other party calls, session log writing services, and messengers. In addition, a voice signal is generated using the wireless ear hook 100 is processed, and the vocal signal concerned is processed in a state where external noise is shielded, whereby not only a speech recognition rate but also a quality of the sound from the speaker and the speaker's voice can be improved.

For example, as in a case where a meeting log writing service is provided in the communication processing system of the wireless earhook according to the present invention, a meeting log can be recorded in response to the order in which a plurality of session participants spoke through the on each smartphone 200 Executed program to write minutes of meetings. Even if a plurality of speakers express their opinion at the same time in the present invention at this point in time, only the voice of the relevant speaker is processed in the present invention, since one in the 3 until 5 shown in-ear microphone 2 is used, whereby a speech recognition rate can be improved. In addition, it is possible to write the translated meeting minutes even if the language of each user terminal is different by using the interpreter function described above. Further, as described in the interpreter function described above, it can be applied to a case where different languages are used in the left earphone 110 and the right earbud 120 for a smartphone 200 be used.

Moreover, in the case of providing a messenger service in the communication processing system of the wireless ear hook according to the present invention, the speaker's voice through the one in each smartphone 200 The running messenger program is converted into text and transmitted to the other party, and it is possible to transmit an accurate text because the speech recognition rate is improved as described above,

Such services as a transcription service of meeting minutes and a messenger service are also possible even if there is outside noise, and this is made possible by a noise-shielding ear hook. That is, as in the 3 until 6th shown, when there is external noise, the speaker's voice spread through the mouth and external noise are though through a through hole ( O ) of the housing 1 flowed in, but since it is through a micro-hole ( H ) of the resonance housing 4th or a through hole ( O ) and a network 5 of the resonance housing 4th and only the speaker's voice, which is spread through the Eustachian tube to the ear canal, into the in-ear microphone 2 has flowed in and signal-processed, the speaker's original sound, which does not contain any outside noise, can be smoothly restored. That is, as the speech recognition rate is improved, it is possible to transmit accurate voice. Furthermore, since the outside noise is blown through a micro hole ( H ) of the resonance housing 4th or a through hole ( O ) and a network 5 of the resonance housing 4th shielded and the inflow into the back hole ( bra ) of the speaker driver unit is blocked in advance, the quality of the sound from the speaker can be improved.

In the meantime, it is described in the present embodiment that the services such as a writing service for session logs and a messenger service in one wireless ear hook 100 and a smartphone 200 can be provided, however, the services can also each be provided separately from the left earbud 110 and the right earbud 120 having a smartphone 200 are connected. That is, the role of a master or a slave for the left earbud 110 and the right earbud 120 can with a control part 220 of the ear hook can be set (real-time switching). For example, by clicking on an icon that can be accessed via an app on the smartphone 200 is displayed, the master or slave role of the wireless ear hook 100 can be switched in real time. Furthermore, an ear hook, in which the voice input takes place through speech recognition, etc., can be automatically set to the master ear hook.

It also works in the case of wireless communication between the smartphones 200 using such a wireless ear hook 100 an accuracy of the speech recognition rate in the ear hook 100 as an important factor. That is, it is necessary to improve a speaker's speech recognition rate in the presence of outside noise, and therefore technology for shielding against outside noise is required. The following are the structure and function of the ear hook 100 described.

First, the types of holes used in describing the present invention will be described.

Back hole ( bra ): A hole at the end of the rear of the speaker-driver unit;

Micro hole ( H ): Hole with a diameter of 100 µm or less, or preferably 40 µm or less;

Through hole ( O ): A hole larger than 100 µm in diameter.

In the following, an example in which a noise shielding ear hook applied to the present invention is implemented will be described by a specific embodiment.

Meanwhile, the order of description of the embodiment of the present invention is as follows.

First, a description will be given of a case where a speaker driver unit and an in-ear microphone are installed inside a noise-shielding ear hook of the present invention ( 3 until 5 ). Next, a description will be given of a case where a speaker driver unit, an in-ear microphone, and an outside microphone are installed inside a noise-shielding ear hook of the present invention ( 6th ).

In addition, the technology presented in the present invention can be applied to a case where a speaker driver unit and an outer ear microphone are installed inside or only one speaker driver unit is installed inside.

3 Fig. 13 is a conceptual diagram of a noise shielding ear hook as an embodiment applied to the present invention.

Indicating 3 A noise shielding ear hook of the present invention comprises the following parts: a housing 1 , in which a through hole ( O ) is trained; an in-ear microphone 2 that's inside the case 1 is formed and collects the voice transmitted from the ear canal, and a speaker driver unit 3 that are inside the case 1 is formed and emits a sound to the ear canal.

Here, in the present invention, there is also a resonance housing 4th at the end of the rear of the speaker driver unit 3 formed, in which the rear hole ( bra ) is trained.

At the same time is in the resonance housing 4th a micro hole ( H ) formed with a size that is shielded from outside noise.

Meanwhile, it is possible to prevent the inflow of outside noise by opening the micro-hole ( H ) in the position of the rear hole ( bra ) the speaker driver unit 3 can be formed using a laser, but there is a disadvantage that the processing cost increases.

Therefore, in the present invention, it becomes a minimum diameter of a hole in the resonance case 4th designed that can shield outside noise. Concretely, it is preferable to make a micro-hole ( H ) with a diameter of 100 µm or less and 40 µm or less, respectively. Preferably it is good to have a micro-hole ( H ) of less than 40 µm.

It can also be used in a speaker driver unit 3 a dynamic driver unit and a balanced armature driver unit can be selectively used. When the dynamic driver unit is used as a speaker driver unit 3 is used, the resonance housing 4th be covered in a shape similar or identical to the shape of the back in which the back hole ( bra ) and is generally cylindrical in shape. In the same way, the resonance housing 4th when using a balanced armature driver unit as the speaker driver unit 3 used, be covered in a shape similar or identical to the shape of the back in which the back hole ( bra ) is trained. Then the contact area between the back of the speaker driver unit 3 and the resonance case 4th sealed.

In the present embodiment, although a case where the in-ear microphone 2 and the speaker driver unit 3 configured individually, but multiple configurations can be deployed.

Although it is shown as an example in this embodiment that the installation rooms SP1 and SP2 using the inner walls 11 and 12th as well as the resonance housing 4th are separated, the installation rooms ( SP1 , SP2), however, can be separated using the housing, the inner walls which are separable from or integrally connected to the housing, and the printed circuit board (PCB), etc. That is, the installation rooms SP1 and SP2 can be separated using an insulator including a case, inner walls, printed circuit board, and so on. Therefore, if a resonance space ( RS ) is formed with a case, an inner wall, a circuit board, etc., a micro-hole ( H ) formed in the housing, the inner walls, the printed circuit board, etc.

If an inner wall is used as an insulator here, a resonance chamber ( RS ) be formed in a cylindrical or polygonal cylindrical shape that extends toward the speaker driver unit 3 extends from the inner wall, in which a micro-hole ( H ) is trained. That is, in the case of the dynamic driver unit, a resonance space ( RS ) can be formed in a normal cylindrical shape, and in the case of the symmetrical armature drive unit, a resonance space ( RS ) be formed in a normal square column shape. Of course, as described above, it is preferable to have a shape that is a shape of the rear of the speaker driving unit 3 is similar or identical to it. And doing so becomes the contact area between the back of the speaker driver unit 3 and the resonance case 4th sealed.

In addition, in the case of using a circuit board as an insulator, a printed circuit board (PBC) can be conveniently mounted so that, since the circuit board is usually a flat plate, it is the cut-out portion of the housing 1 is sealed at a predetermined position. That is, if the case 1 is cut out in a predetermined position, the circuit board has a structure in which the opened area is completely sealed with the circuit board. And then one face of the circuit board faces the installation room SP1 and the other surface to the installation space SP2, the inner wall 11 that separates the installation space SP2, touches and seals the other surface of the circuit board. Therefore, the speaker driver unit and the in-ear microphone can be based on the inner wall 11 to be installed separately.

As described above, the micro-hole formed in an ear hook connects ( H ), to which various methods can be applied, between the back hole ( bra ) the speaker driver unit 3 and that in the case 1 formed through hole ( O ) through.

The technology for separating the installation rooms ( SP1 , SP2 ) will be described in more detail.

The inside of the case 1 is through an insulator to an outside space SP1 and an interior SP2 divided. In the present embodiment it is shown by way of example that the insulator consists of the inner walls 11 and 12th and the resonance case 4th consists. Of course, it is also possible that the isolator just comes from the resonance housing 4th is composed.

The interior SP2 is through a first inner wall 11 separated and an in-ear microphone 2 is in one through the first inner wall 11 separate room installed, and a speaker driver unit 3 is installed in another room.

By adding a speaker driver unit 3 and a resonance case 4th are in the first inner wall 11 and the second inner wall 12th are inserted, the outer space ( SP1 ) and the sound channel in the loudspeaker ( SH ) spatially separated. An in-ear microphone 2 can be in the middle of the collective channel of the voice in the microphone ( VH ) must be installed. That is, in a room where the in-ear microphone 2 is attached, a collective channel of the voice is formed in the microphone ( VH ) out and in another room where the speaker driver unit 3 is attached, a sound channel is formed in the loudspeaker ( SH ) and a resonance chamber ( RS ) the end. As a result, one room is used as a collective channel for the voice in the microphone ( VH ), whereby in the nozzle part a collective channel of the voice in the microphone ( VH ) using the first inner wall 11 and the housing 1 is formed and in the middle part of the main body a collective channel of the voice in the microphone ( VH ) using the first inner wall 11 and an extra inner wall of the voice guide (not shown in drawings) can be formed. Therefore, the straightness of voice input can be improved. Meanwhile, the other room is used as a sound channel in the loudspeaker ( SH ) and in the nozzle part a sound channel in the loudspeaker ( SH ) using the first inner wall 11 and the housing 1 formed and in the middle part of the main body a sound channel in the loudspeaker ( SH ) or a resonance space ( RS ) with an alternative use of the first inner wall 11 , the second inner wall 12th , or the housing 1 be formed. As a result, the straightness of the sound reproduced from the speaker can be improved, and the reproduction with low sound can also be carried out smoothly.

In addition, it is preferable that the diameter of a micro-hole formed in the insulator ( H ) compared to the thickness of the insulator. For example, the ratio of the diameter of a microhole H to the thickness of the insulator can be set in the range of 1: 100 to 1000, and it is preferably set to 1: 1000 or more. For example, if the thickness of the insulator is 1 mm (1000 µm), the diameter of the micro hole ( H ) can be set in the range from 1 to 10 µm.

The thus configured noise-shielding ear hook of the present invention shields outside noise by using the micro-hole formed in the insulator ( H ) with the insulator including a case, an inner wall, a circuit board, etc., and the air pressure inside and outside of the ear hook can be kept the same. In addition, a sound can be amplified sufficiently because a resonance space ( RS ) between the micro hole ( H ) and the back including the back hole ( bra ) the speaker driver unit 3 is trained.

Furthermore, since the micro-hole ( H ) with a relatively small diameter between the back hole ( bra ) and the through hole ( O ), a function of the low-pass filter is carried out. When the data processed by this is transmitted over a network, the high / low frequency audio frequency is removed in the bandwidth to reduce the amount of data, and it is found that a signal that has passed through the micro-hole ( H ) does not affect the amount of data as it corresponds to the low audio frequency (less than 100 Hz).

4th Fig. 13 is a conceptual diagram of a noise shielding ear hook as another embodiment applied to the present invention.

Meanwhile, in the description of 4th only differences too 3 to avoid overlapping descriptions.

Indicating 4th is in the present embodiment a through hole ( O ) in the resonance housing 4th formed, the through hole ( O ) with a network 5 is covered.

That is, a through hole ( O ) is formed with a diameter 10 times or more larger than the minimum diameter ( 40 µm) of a hole, which can shield outside noise, and it can pass through a net 5 with a density inversely proportional to the diameter of the through hole ( O ) is to be covered. At the same time, the density of the network 5 can be determined taking into account the vote and is preferably set in the range of ± 20% of the density. Since outside noise is shielded by making a through hole ( O ) and a network ( 5 ) are combined with each other, not only can external noise be effectively shielded by this mutual complementation, but the air pressure can also be kept the same inside and outside the ear hook.

As described above, considering that the diameter of the hole that can shield external noise is possible around 40 µm, the insufficient ability to shield against noise is compensated for after a micro-hole ( H ) is drilled from 0.4 to 0.6 mm, which is about ten times larger, and when a through hole ( O ) for acoustic coordination with a high-density network 5 from 300 until 600 Numbers or more is covered, external noise can be prevented from entering the ear canal and the in-ear microphone 2 have flowed in. That is, a desired technology of the in-ear microphone 2 can be implemented.

Meanwhile, in the present embodiment, a case of covering a through hole ( O ) using a network 5 although written on, but a through hole ( O ) can be covered using a pad (not shown in drawings) in which a micro-hole is formed. In addition, a network 5 at the in 1 formed micro-hole ( H ) to be covered for the purpose of voting etc.

Like it in the 3 and 4th is described, a sound quality can be improved and an inflow of outside noise into the in-ear microphone 2 can be prevented because a resonance case 4th for shielding against external noise at the end of the rear of the speaker driver unit 3 is designed by shielding the inflow of outside noise. That is, the following problems can be solved that external noise caused by the at the end of the rear of the speaker driver unit 3 trained rear hole ( bra ) have flowed in, are transmitted to the ear canal of the user, or that external noises along the sound channel in the loudspeaker ( SH ) and the collective channel of the voice in the microphone ( VH ) into the in-ear microphone 2 can be entered. At the same time, not only the resonance space ( RS ) behind the membrane of the speaker driver unit 3 further developed, but also because the resonance space ( RS ) through the through hole ( O ) of the housing 1 connects through, the back volume can be improved and the same air pressure can be maintained. Further, as the low tone of the speaker driver unit 3 is amplified, the sound quality can be improved.

Concretely, in the present invention, micro-hole ( H ) of 100 µm, preferably around 40 µm, which can shield outside noise, directly in the resonance housing 4th be formed. At the same time, in the resonance housing 4th a through hole ( O ) with a diameter of more than 100 µm and with a mesh 5 be covered with a density inversely proportional to the diameter of the through hole ( O ) is. In addition, the micro-hole ( H ) of 100 µm, preferably around 40 µm, which can shield outside noise, in the resonance housing 4th formed, and the relevant micro-hole ( H ) can be covered for voting.

Therefore, the air pressure inside and outside the ear hook is measured using the resonance housing ( 4th ), in which a micro-hole ( H ) is designed, kept the same and the through hole ( O ) The inflow of external noise is shielded.

By improving the back volume at the same time, since a resonance space ( RS ) through the resonance housing ( 4th ) is expanded, the sound quality can be improved by amplifying the low tone as a sound even when operating the speaker driver unit 3 the sound through a back hole ( bra ) and a micro hole ( H ) (a through hole ( O ) and a network ( 5 ), a micro-hole ( H ) and a network 5 ) is output in reverse, through the micro-hole ( H ) of the resonance housing 4th (a through hole ( O ) and a network 5 , Micro hole ( H ) and a network 5 ) has passed through, only the low audio frequency of 100 Hz or less is output, so a sound coming through the through hole ( O ) of the housing 1 oozes out, can be shielded.

Meanwhile, the one in the 3 until 6th featured noise-shielding ear hooks a space for installing a resonance case 4th because the resonance case 4th inside the case 1 is trained.

In addition, a method of directly forming the micro-hole in a case, an inner wall, a circuit board, etc., with which an insulator can be formed, is described.
