Description

[0001] The present invention relates to a method for performing a sound search service,

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a headphone, and more particularly, to a headphone equipped with a broadband connection module to enable a headphone user to receive music service anytime, anywhere, and methods for supporting the same.

Generally used headphones can not listen to music independently if they do not have separate communication or storage device, regardless of whether they are wired or wireless. That is, the user of the headphone has a disadvantage of separately purchasing a music playback audio device capable of listening to music.

In addition, although the wireless headphone plays music with a music playback audio device mainly in a local area network, when the user has audio devices which are separated from the playback audio device or have no local area network, the user can not listen to music continuously through the headphones .

In particular, a communication modem for a local area network such as Bluetooth or Wi-Fi has high mounting capability for a headphone, but the headphone can not network with the wireless communication network by itself. The headset equipped with a Bluetooth modem is inconvenient to turn on the Bluetooth and connect to the device authentication every time the connection is attempted to connect to the network, and it is inconvenient to find and use the AP network with which the headphone with the Wi- There is. In addition, there is a limit to the continuous use of the network when data traffic is high, so it is not the best network solution to enjoy music freely anytime and anywhere.

In the case of a broadband network, the LTE (Long Term Evolution) system, which is one of the wireless access systems, has a limitation in that it can not standardize different frequencies depending on each communication company. That is, the LTE terminal subscribed to one communication company can not connect to the LTE network of another communication company.

Moreover, the headphones must be worn by the user. In the conventional technology, when a broadband communication modem capable of connecting to a broadband network is installed, the size of the headphone becomes too large. That is, since the existing headphones basically have a portion occupied by the parts for sounding, if the size of the headphones is out of the standard size or more to install a broadband communication modem, the user can not wear them.

1 is a view showing a structure of a headphone of the present invention.

Referring to FIG. 1, a headphone 100 is a broadband wireless access module for supporting a broadband wireless connection to a network. The broadband wireless access module includes an LTE module 10, a service transmission / reception unit 20 for receiving a music service, A text to speech engine 40 for outputting information about a sound source to be currently provided to a headphone user by voice, authentication related information, music information, and / or sound source information A processor 60 connected to each component included in the headphone to control the components, a speaker 70 for outputting a sound source to a user, a user's voice, A microphone 80 for recognizing (or inputting) external noise, a battery 90 for providing power to the headphone, and a power supply 95 connected to the battery for controlling power supply to the headphone Or it may include more.

The LTE module is one of the broadband wireless connection modules capable of connecting to the LTE network and / or the LTE-A network.

2, the LTE module 10 for a headphone includes an LTE antenna module 12 for transmitting a radio signal and a Radio Frequency (RF) module for converting an analog signal into a radio signal in cooperation with the LTE antenna module. Module 13 as shown in FIG. In addition, the LTE module 10 for headphones further includes a connection control module 14, a memory 15 and a processor 16.

The connection control module 14 supplies power to the LTE module device, inputs / outputs the LTE communication signal, and determines whether or not the LTE module device is mounted. In addition, the connection control module 14 is equipped with a subscriber identity module device (e.g., a headphone identification device).

At this time, the memory 15 may include frequency information for each communication company. This memory is a flash memory that stores caching information required for uplink and downlink of the LTE frequency and plays a role of supporting some LTE data transmission speed.

The processor 16 can adjust the LTE frequency received through the antenna module connected to the LTE module device to function in accordance with the range,

3 is a diagram showing an example of the configuration of the LTE antenna module 12 included in the LTE module for headphones.

3, the LTE antenna module 12 includes a frequency transmitter 121 for transmitting a radio signal for connection to a broadband network and supporting a data service, a frequency receiver 122 for receiving such a radio signal, And a frequency interface unit 123 for converting LTE wireless data services between frequency bands into mutually applicable ones.

Basically, the wireless devices supporting the wireless communication module are optimized for the frequency band provided by the registered communication company. Therefore, access to the same LTE network and data service can not be received through a frequency band other than the registered communication company. However, the headphones proposed in the present invention can access the LTE network through the frequency interface unit 123 through communication companies having different LTE frequency bands.

That is, the frequency interface unit 123 can convert the frequency of the network to match the data to be provided to the headphone and the frequency coverage of the headphone, so that different frequencies can be detected by the headphones.

For example, the LTE antenna module 12 is optimized to operate on a frequency band that is registered by a carrier registered on the basis of Korea. However, the headphone device described in the present invention is equipped with all information on frequency bands that can be supported by the LTE system. Therefore, if the subscriber identification information to be registered in the communication carrier is registered in advance in the communication provider network, the user of the headphone proposed in the present invention can provide the data service optimized for the communication carrier network registered by the user using the headphone device Can receive.

Fig. 4 is a sectional view showing the earbud 41 constituting the headphone proposed by the present invention, and Fig. 5 is a view showing an example of constituent elements provided in the earbud 41. Fig.

The earbud of the headphone is a face that contacts the ear portion of the user, and is a portion where the components described in Fig. 1 are mounted (i.e., included). The ear bud 41 of the headphone is composed of a pair of left and right ear pairs. At this time, each of the ear buds of the headphone includes a driver 411, a baffle 412, and a housing 413.

The housing 413 accommodates the driver 411 and the baffle 412, and forms an acoustic space that naturally rings. The driver 411 may be of a coin type that drives a voice coil fixed to the diaphragm 51 between the magnet and the yoke, similar to a normal speaker. The baffle 412 is a partition for preventing the sound generated through the driver, that is, the speaker, from being diverted to the outside.

When the housing 413 and the baffle 412 are coupled, the height is preferably within 50 mm. This is to configure the size of the headphones which is most comfortable to wear when worn by the user.

Fig. 5 is a view for explaining the space of the sprinkler headphone. In order to realize the music sound of the headphone, the earbud 41 includes a terminal board, a resistor, a frame, a magnet, a pole piece, a protector, Should be. In addition, in the case of a wireless headphone, it should be further configured to include a rechargeable battery (52, 90). That is, the headphone of the present invention has a configuration in which a headphone component and a LTE module 12, which is a broadband communication modem, are mounted in a space of 50 mm or less on the side, and the collision between components is minimized when the LTE module is mounted.

5, the left earbud includes the diaphragm 51 and the right earbud may include the LTE module 10 and the rechargeable battery 52. However, this is only an example, and the configuration included in the left and right earbuds can be changed according to the manufacturing process.

FIG. 6 is a diagram illustrating one of methods by which a headphone equipped with an LTE module is provided with a high-quality streaming service according to an embodiment of the present invention.

Referring to FIG. 6, a user using a headphone operates the power supply unit 95 of the headphone to turn on the headphone (S601).

When the headphones are turned on, that is, when the headphones are turned on, the processor 60 of the headphone can control the LTE module 10 to perform the authentication process with the authentication server 200 through the LTE network, which is one of the broadband wireless communication networks. That is, the processor of the headphone transmits the authentication information stored in the memory 50 or 15 to the authentication server through the frequency transmitter 121 (S602 and S603).

In this case, the authentication information may be an identifier for identifying a subscriber terminal subscribed to the LTE network or a unique identifier assigned to the headphone terminal. In the embodiments of the present invention, it is assumed that the LTE module is installed in the headphone, and the headphone is independently accessed and provided to the LTE network, so that the authentication information is an identifier uniquely assigned to the headphone terminal. That is, the authentication server 200 of the present invention can perform a function of identifying a headphone equipped with an LTE module with a general LTE terminal. Further, information on the play list of the user and the like may be added to the authentication information.

The authentication server 200 transmits the authentication information to the viewing server 300 when authenticating the corresponding headphone through the authentication information received from the frequency transmitter 121 of the headphone. The viewing server 300 performs a function of providing the streaming service to the headphones identified through the authentication information (S604).

The processor 60 of the headphone can recognize the music menu selected by the user through the music application after performing the authentication process with the authentication server through the LTE network using the LTE module. The music application may be stored beforehand in the headphone, or the processor of the headphone may replace the function in place of the music application (S605, S606).

The processor of the headphone can transmit the service request information for the music menu selected by the user to the listening server 300 by using the service transmitting unit 20. [ The service request information may include play list information corresponding to the menu selected by the user, music identification information and / or authentication information for one or more pieces of music selected by the user (S607 and S608).

The play list information is a list of titles of songs preset by the user. The music identification information for the specific music requested by the user means information for identifying the music piece selected by the user through the menu.

The viewing server 300 receives the service request information matching the authentication information received in step S604 (S608).

If authentication information is included in the service request information in step S608, step S608 may be performed independently of step S604. However, if authentication information is not included in the service request information in step S608, steps S604 and S608 may be continuously performed in one session. That is, when the authentication is completed, the processor of the headphone can transmit the service request information to the listening server while being connected to the authentication server and the listening server.

Upon receiving the service request information from the listening server 300, the listening server delivers the service request information to the song information server 400, and the song information server 300 transmits the play list and / or music identification information From the content database (DB) and transmits the detected sound source to the listening server 300 (S609 and S610).

The viewing server 300 may provide the streaming service requested by the headphones. That is, the viewing server 300 provides the streaming service over the LTE network, and the service receiving unit 20 of the headphone receives the streaming service (S611).

The TTS engine outputs a voice to the user through the TTS algorithm to determine what music or playlist is provided in the received streaming service. Accordingly, the user can check which title of the music currently outputted from the headphone is or which music of the playlist is streamed (S612).

If a headphone does not have a TTS engine and a display unit is provided, the processor of the headphone can display the list name of the music title or the play list on the display unit in a non-voice character.

The processor may execute the music application and provide the received streaming service to the user (S613).

The above-described process will be described again from the viewpoint of the user. When the user turns on the power of the headphones, the LTE module 12 of the headphone performs the authentication process with the authentication server 200 through the LTE network. The user can select one or more songs, or select one or more playlists by operating a specific button, touch screen or touch pad while the power is on. The headphone transmits service request information including one or more pieces of music and / or play list information input by the user to the network through the service transmission unit. Then, the headphone can receive the streaming service provided on the basis of the service request information in the listening server 300, and can provide the streaming service to the user through the speaker.

In one aspect of the present invention, when the authentication information identifies the headphones on which the general LTE terminals and the LTE module are mounted, the listening server differentiates the headphones equipped with the LTE module from the general LTE terminals Service can be provided. For example, if the listening server recognizes that the LTE terminal requesting streaming is a headphone, it can provide only a high quality sound source.

In general, the streaming service is provided at a music level with the lowest coding rate. This is because, in general LTE terminals, even if they are streamed at a music level (for example, lossless music) having a high coding rate with high quality, it is not necessary to provide a high quality sound source because the performance of the speaker is generally lower than that of the headphones .

However, in the case of the headphone user, the LTE module and / or the service transmission / reception section are provided for the music service, so that high quality music can be streamed. For example, if there is no specific request from the headphone user, the listening server 300 provides a streaming service with a predetermined high quality music level, and if the user has a requested music level, provides the streaming service of the corresponding level . In this case, the service request information used in step S608 may further include information on the music level.

FIG. 7 is a diagram illustrating a method for receiving a music download service by a headphone equipped with an LTE module according to an embodiment of the present invention.

The description of the steps S701 to S710 is similar to the description of the steps S601 to S610, so that the description will be omitted. 7, the download server 600 replaces the role of the impression server 200 in place of the impression server 200, but the download server 600 can download music corresponding to the service request information requested by the user .

The downloaded songs are received by the service receiving unit 20 of the headphone and transmitted to the processor. The processor stores the downloaded songs in the memory 50 and then provides the music through the music application when requested by the user (S711, S712, S713).

If the capacity of the memory 50 is full through downloading, the processor can store the downloaded songs in the virtual DB 700 existing on the network using the LTE module 10 or the service transmitting / receiving unit 20 (S714).

Of course, even if the memory is not full according to the user's selection, the headphone can store downloaded music in the virtual DB 700. [

6 and 7, the LTE module 10 transmits the authentication information to perform the authentication process, and the service transmitting and receiving unit 20 transmits the service request information indicating the music or the play list selected by the user. However, the LTE module 10 and the subscriber transceiver 20 may be configured separately as shown in FIG. 1, but may be configured as one communication module. In this case, it is assumed that the LTE module transmits authentication information and service request information.

FIG. 8 is a diagram illustrating one method of detecting external music in a headphone and providing it to a user according to an embodiment of the present invention.

Referring to FIG. 8, a user can listen to music from the outside while carrying the headphone 100. However, if the user does not know what the music is, the user can operate the music find button (not shown) of the headphone. The music finder button may be provided in the housing 413 of the headphone earbud 41. When the music search button is operated, the processor 60 of the headphone turns on the microphone 80 and detects external music. The time for detecting the external music may be set in a range of 5 seconds to 30 seconds in short (S810).

The processor 60 records the detected external music and extracts the sound source DNA of the music. The sound source DNA may be a unique melody or natural frequency of each music (S820, S830).

The processor 60 of the headphone transmits the sound source DNA information to the sound source DNA server via the LTE network through the service transmission / reception unit 20 and / or the LTE module 10 (S840).

The sound source DNA server (not shown) retrieves and detects music corresponding to the sound source DNA information from the sound source DNA database. Thereafter, the sound source DNA server transmits the detected music to the service receiving unit 20 and / or the LTE module 10 of the headphone, and the headphone receives the transmitted external music (S850).

Through these processes, the processor of the headphone can provide the detected external music to the user through the speaker.

8, when the user operates the music search button of the headphone, the headphone is turned on, and the LTE module 10 performs the authentication process with the authentication server 200. Then, the music search service can be performed on the LTE network by transmitting the sound source DNA information from the LTE module 10 or the service transmission / reception unit 20 to the sound source DNA server.

If the user operates the music search button of the headphone while the headphone is turned on, it is not necessary to perform the authentication again if the headphone performs the authentication process with the authentication server. However, the authentication process with the authentication server is performed If not, the authentication can be performed again.

9 is a view showing one of methods for detecting external noise in a headphone and providing the sound to a user according to an embodiment of the present invention.

Referring to FIG. 9, a user may move to a place where external noise is present while listening to music through the headphone 100 or performing a call. At this time, the processor 60 of the headphone can sense the external noise inputted through the microphone 80. [ There are two ways in which headphones can detect external noise: (1) the user presses the external noise detection button, (2) manipulates the touch pad for external noise detection, and (3) Can be detected. The time for detecting the external noise may be set in a range of 5 seconds to 30 seconds in short (S910).

The processor 60 measures the magnitude of the sensed external noise and compares the measured volume with the volume of the current headphone (S920).

If the external noise is larger than the volume of the headphone, the user can not provide an optimum listening environment. Therefore, the processor 60 of the headphone can adjust the volume of the headphone in consideration of external noise (S930).

For example, the processor 60 of the headphone can provide an optimal listening environment by increasing the volume to a predetermined size previously stored, compared with the measured external noise.

Alternatively, the processor 60 of the headphone can increase the volume in proportion to the measured external noise, so that the user can listen to music at a volume of a desired size regardless of external noise. For example, if the external noise is 0 and the user is listening to music at a volume of 30dB, if the external noise is measured at 15dB, the headphone will increase the volume to 45dB so that the volume experienced by the user will be 30dB . Thus, the user can listen to the music in a certain size despite the external noise.

However, even if the external noise is too great, if the volume of the headphone is further increased, it may adversely affect the auditory sense of the user. Therefore, the volume of the headphone, which is further increased in height, can be set in consideration of the listening limit of the person. That is, in a situation where external noise is too great to listen to music, the user can be informed that the external noise is too large without raising the volume. For example, if the noise is too large, the TTS engine may be driven to inform the user that the noise is too loud to pause music playback.

The headphone can control volume by considering external noise such as music player, high sensitivity microphone, TTS engine.
