Abstract

We provide a fully wireless earphone assembly with a TES treatment function that eliminates problems such as the configuration and wiring of terminal fins for separate charging and the enlargement of the earphone body. [Solution] The present invention relates to a fully wireless earphone assembly equipped with a TES treatment function. When a user LS stores the earphones (RE,LE) of the present invention in the charging slot R1 of the charging cradle R without using them, the charging terminal Tr below the charging slot R1 and the earphone terminal Te of the earphones (RE,LE) enter a charging standby mode in which the battery voltage (Vin) is connected to the terminal terminal inside the charging cradle R by the connection between the terminal terminals. In this state, the TES treatment function of the earphones (RE,LE) is not activated due to the absence of the link cable LC.

Description

Technical Field

[0001] The present invention relates to a completely wireless earphone assembly having a TES treatment function. More specifically, in a completely wireless earphone having a pair of left and right earphones separated electrically and based on signal transmission conforming to the Bluetooth (registered trademark) standard, the present invention relates to a completely wireless earphone assembly configured to enable not only listening by transmission of an acoustic signal but also an electrical TES treatment function that can be executed by a user's selection, and to improvements in such a configuration.

Background Art

[0002] In recent years, completely wireless earphones (TWS Earphone: True Wireless Stereo Earphone) based on signal transmission conforming to the Bluetooth (registered trademark) standard have been positioned as standard acoustic listening means.

[0003] Completely wireless earphones provide a pair of left and right earphones as acoustical units in an electrically separated form, eliminating the need for another electrical connection between these earphones, and receiving and reproducing sound from an acoustic device in accordance with the Bluetooth (registered trademark) communication standard.

[0004] In connection with completely wireless earphones that can selectively perform the TES treatment function of the present invention, consideration has been given to providing more improved functions.

[0005] (1) From a psychiatric perspective, insomnia, depression, ADHD, neurasthenia, decreased concentration, fatigue, etc. have emerged as serious problems for modern people. In particular, in Russia and northern Europe where winters are long, many efforts and attempts have been made to improve these symptoms by applying electrical or magnetic stimuli to the human body in response to psychiatric pathological phenomena caused by the climate.

[0006] In recent years, the therapeutic techniques of TES (Transcranial Electrical Stimulation) or TMS (Transcranial Magnetic Stimulation) have been theoretically and experimentally proven to have significant effects through numerous papers and clinical trials, and TMS and TES stimulation devices are already widely used in many psychiatric hospitals and adolescent mental health hospitals in South Korea.

[0007] (2) In particular, TES treatment has been called for and is rapidly spreading due to its non-pharmacological, non-invasive, and non-serious toxicity characteristics, as well as its extremely low risk of medical errors.

[0008] (3) Compared to conventional methods, TES and TMS devices for treating mental health pathologies are very expensive because they are configured in a chair in which the patient sits during treatment, and include multiple electrodes (adhesive pads), an electrical stimulation circuit, and a fine adjustment panel as an integrated device, making them only available in large hospitals and above.

[0009] Considering these points, the inventors have determined that it is technically possible to apply TES treatment functions to headsets, earphones, etc., and have previously devised numerous technologies suitable for this purpose as prior applications.

[0010] In particular, the inventor has previously filed a Korean patent application, No. 2194226, for a "bone electrocardiogram device with TES treatment function," in order to provide TES treatment function to earphones and headsets in a portable form for widespread use among the general public.

[0011] Furthermore, building upon the above prior application, we filed Japanese Patent Application No. 2023-202292 on December 6, 2023, for a "fully wireless earphone assembly with TES therapeutic function," disclosing the technical concept for application to fully wireless earphones.

[0012] The configuration described above provides a pair of left and right earphones with a link cable essential for transmitting TES signals through the human body. The TES treatment function is selectively provided by connecting the link cable when using the function and by removing the link cable from the earphones to enter acoustic listening mode.

[0013] While the configuration of the present inventor's prior application is highly convenient, the connection terminal between the link cable and the earphone only serves to transmit the TES signal. Therefore, in order to charge the earphone unit itself, it was necessary to provide a separate pair of contact terminals for charging on the earphone housing.

[0014] Furthermore, from a design perspective, while the TES signal generation unit is located on the housing board of either the left or right earphone, this requires the left and right earphones to be the same size, which presents the problem of potentially increasing the overall size of the earphones.

[0015] Therefore, in addition to the increased size of the earphones, the complex configuration, increased manufacturing costs, and the high risk of failure due to repeated user use were also due to the need to condense the operating circuit board, charging terminal fins, and wiring or circuit board contacts between these components into the very narrow space of the earphone body. [Prior art documents] [Patent Documents]

[0016] [Patent Document 1] Korean Patent Publication No. 2194266 (2020.12.16) [Patent Document 2] U.S. Patent No. 9,686,603 (June 20, 2017) [Patent Document 3] U.S. Patent Publication 2009 / 0185699 (July 23, 2009) [Patent Document 4] U.S. Patent Publication 2015 / 0382115 (2015.12.31) [Patent Document 5] U.S. Patent Publication 2017 / 0368329 (2017.12.28) [Overview of the project] [Problems that the invention aims to solve]

[0017] Therefore, there is a need for an electrical circuit configuration that allows for the design of various earphone housing designs while maintaining a compact volume. Furthermore, there is a desire for a fully wireless earphone assembly that simplifies the overall configuration, reduces production costs, and minimizes wear and failure due to frequent terminal contact by having the terminal section for electrical connection of the earphone serve as both a terminal for conducting electricity into the human body via the TES signal and a charging terminal for charging.

[0018] The present invention will be based on an explanation of the conventional, prior-filed fully wireless earphone assembly with TES treatment function, which was previously filed by the present inventor as described above, with reference to Figures 9 and 10.

[0019] In the present inventor's prior application, as shown in the external perspective view in Figure 9 and the circuit block diagram in Figure 10, the circuit sections housed in the housings (H2, H2') of a pair of left and right earphones (RE2, LE2) included a Bluetooth® communication module 210, a memory 215, a decoding unit 220, a digital-to-analog converter 225, an audio amplification unit 230, speaker units 241, 242, and a control unit 290 operated by a user interface 280.

[0020] In the circuit sections housed in the housings (H2, H2') of a pair of earphones (RE2, LE2), one of the left or right circuit sections is further provided with a frequency generator 250 for generating low-frequency signals to realize ES therapeutic functions, and a TES signal amplifier 260 for amplifying the generated low-frequency signals, which are signal-connected to a control unit 290 operated and controlled by the user interface 280, in addition to the acoustic data reception and playback circuit described above.

[0021] The TES signal amplification unit 260 allows the user LS to vary the amplification degree via the user interface 280. Also, although the frequency generator may be configured as a separate circuit unit as described above, the control unit 290 can directly generate a low-frequency signal.

[0022] As circuit units respectively housed in the housings (H2, H2') of the pair of left and right earphones (RE2, LE2), it includes a Bluetooth (registered trademark) communication module 210, a memory 215, a decoding unit 220, a digital-analog converter 225, an audio amplification unit 230, speaker units (241, 242), and a control unit 290 operated by the user interface 280.

[0023] The earphones (RE2, LE2) are respectively provided with female connectors (Female connector: FC2, FC2'), and a link cable LC1 having male connectors (Male Connector: MC2, MC2') at both ends for electrically and selectively connecting between the pair of female connectors FC2, FC2' is provided. The pair of left and right earphones (RE2, LE2) transmit or block the TES signal by connecting and disconnecting the link cable LC1.

[0024] In the above configuration, since another electrode terminal fin for charging the battery (not shown) of the earphones (RE2, LE2) is required, the configuration is very complicated. The frequency generator 250 signal-connected to the TES generation signal control unit 290 and the TES signal amplification unit 260 for amplifying the generated low-frequency signal need to be integrated on a substrate and configured in either the left or right earphone. Also, since the intensity of the TES signal preferred by the user LS who wants to receive TES treatment is adjusted by operating the user interface 250 connected to the control unit 290, in case the user LS tries to adjust the intensity of the TES signal while listening to sound for relaxation, the volume operation and operation pattern of the user interface 250 may overlap, making it impossible or restricted to adjust the intensity of the TES signal.

[0025] In consideration of the above problems, in the present invention, by improving the overall circuit and simplifying the terminal connection configuration for charging the battery in the earphone, a completely wireless earphone assembly with an improved configuration capable of selectively executing the TES treatment function that eliminates problems such as the configuration of the terminal fin for another charge, wire routing, and the enlargement of the earphone body is provided.

Means for Solving the Problems

[0026] A fully wireless earphone assembly with TES therapeutic function of the present invention, for embodying the preferred embodiment described above, further comprises a charging cradle as an assembly that enables charging of the earphones by having terminal terminals that connect to the terminal terminals of the earphones, and further comprises a charging cradle as an assembly, wherein the first circuit section, which is an isolated circuit of either one of the left and right separated earphones, has a variable DC / DC converter connected to the control section. The basic technical concept is that the second circuit section, which is a separate circuit of the other of the pair of earphones separated into left and right, includes a TES signal generator for low-frequency TES therapy connected to the control unit, a variable amplifier for amplifying the low-frequency signal, and a link cable (LC) that can be selectively attached to and detached from the terminals of the left and right pair of earphones to electrically connect or disconnect the earphones by attaching and detaching the terminal connection; when the earphones are in use with the link cable detached from the left and right pair of earphones, the left and right pair of earphones function as an acoustic listening means; or when the pair of earphones and the terminals of the link cable are connected, a TES therapy function that conducts the low-frequency signal between the electrodes of the earphones through the user's body; or the acoustic listening function and the TES therapy function can be selectively performed simultaneously.

[0027] Furthermore, the fully wireless earphone assembly equipped with the TES treatment function of the present invention may be configured to selectively switch between charging and usage modes by connecting the terminal of the earphone to the terminal of the link cable and connecting the terminal of the earphone to the terminal of the charging cradle.

[0028] Furthermore, the fully wireless earphone assembly equipped with the TES treatment function of the present invention can be configured such that when the user is listening to sounds on a daily basis, the link cable is stored in the cable storage space of the charging cradle for listening to sounds, and when the user is using the TES treatment function alone or the TES treatment function and the sound listening function together, the link cable is connected to the earphones via terminals, and the TES signal from the variable amplifier that amplifies the TES signal of the TES signal generator in the second circuit section of the earphone storage as selected by the user interface is applied to one of the user's ears to energize it, and the TES signal is electrically connected to the DC / DC converter in the first circuit section of the other earphone, and the TES signal is energized through both of the user's ears while low frequencies are applied to the human body.

[0029] Furthermore, in the fully wireless earphone assembly equipped with the TES treatment function of the present invention, the ON / OFF of the electrical connection between the first circuit section housed in the body housing of the left and right earphones, the second circuit section, and the link cable can be characterized by the connection and disconnection of the electrode body of the terminal using a magnet.

[0030] Furthermore, in the fully wireless earphone assembly equipped with the TES treatment function of the present invention, the charging cradle has a cable storage section having a cable storage space for storing the link cable, and an earphone charging section having a slit-shaped charging slot for storing the earphones, with a charge terminal provided below it as a terminal terminal, and the earphone charging section and the cable storage section can be provided separately from each other or can be stacked together to form a single assembly. [Effects of the Invention]

[0031] This invention can be easily applied to completely wireless earphones, allowing users to easily select and perform TES therapy functions, thus combining acoustic listening and TES therapy.

[0032] The fully wireless earphone assembly with TES therapeutic function of the present invention provides the earphone with a terminal connection configuration that allows simultaneous connection of the charging cradle terminal and the link cable terminal, and provides an improved circuit that can control such connections, thereby improving the simplicity of the product configuration and operational reliability.

[0033] Furthermore, by providing additional means for storing the earphones, the device offers the convenience of minimizing the loss of the link cable. [Brief explanation of the drawing]

[Figure 9]This is an external perspective view showing one of the fully wireless earphone assemblies having TES therapeutic function according to an embodiment of the present invention by the inventors of the present invention. [Figure 10] Figure 9 is a circuit diagram showing one embodiment of the circuit configuration of the prior art embodiment. [Modes for carrying out the invention]

[0035] The present invention will now be described in detail with sequential and accompanying reference to the accompanying drawings.

[0036] Figure 1 shows an external perspective view of the earphone section Ae, which consists of a pair of left and right earphones (RE, LE) of the fully wireless earphone assembly A, and Figure 2 shows an exemplary external perspective view of the earphone assembly inserted into the charging cradle.

[0037] Since the left and right earphones are a symmetrical pair, a reference numeral is assigned to only one of them for explanation, and the same reference numeral in both earphones represents the same component.

[0038] The left and right earphones (RE, LE) of the fully wireless earphone assembly A equipped with the TES treatment function of the present invention may have various shapes and designs.

[0039] Although the illustrated configuration is illustrative, for purposes of the present invention, the body housing B of the earphone (RE,LE) is a long, bar-shaped cylindrical body, and houses a circuit section and a battery for charging (not shown), while the speaker unit 40 for sound listening is housed in an ear unit I connected to the body housing B.

[0040] An electrode M is provided on the outer circumference of the ear unit I, which is inserted into the ear of the user LS. The electrode M is covered or partially exposed with various conductive metals, conductive rubber, or conductive plastics, and its position and shape are determined so that the TES signal is optimally transmitted to the human body by fitting snugly to the inner ear side of the user LS.

[0041] The body bar Bb, which is an extension of the earphone section of the body housing B, is a long bar shape to accommodate insertion into the charging slot R1 of the charging cradle R, as shown in Figure 2.

[0042] An earphone terminal Te is provided as a conductive electrode at the end of the body bar Bb. The earphone terminal Te, as a terminal, is made of a conductive magnetic material such as neodymium, which has considerable magnetic force. This allows it to be attached and detached by magnetic force to conduct electricity, and when in use, the connection is held in place by a strong magnetic force, which is highly convenient.

[0043] The earphone terminal Te has a contact surface in which the central contact piece Te1 and the ring-shaped contact piece Te2 on the outer edge are electrically separated.

[0044] The charging terminal at the end of the charging slot R1 of the charging cradle R shown in Figures 2 and 3, and the charge terminal Tr, which serves as a terminal for rapidly supplying ground and voltage, are provided as terminals for connecting to the earphone terminal Te. Similarly, the above-described configuration of magnetic attachment type terminal connection is preferable.

[0045] This will be explained in conjunction with the block diagram of the circuit shown in Figure 4.

[0046] The first circuit section (C1) of the circuit board housed in either the RE or LE earphones comprises a Bluetooth® communication module 10, a memory 15, a decoding unit 20, a D / A converter 25, an audio amplification unit 30, a speaker unit 40, a control unit 90 operated by a user interface 80, and a DC / DC converter 100.

[0047] The second circuit section (C2) of the circuit board housed in one of the earphones RE,LE includes a Bluetooth® communication module 10, a decoding unit 20, a D / A converter 25, an audio amplification unit 30, a speaker unit 40, and a control unit 90 operated by a user interface 80. A TES signal generator 110, which is a low-frequency generator for TES therapy, and a variable amplifier 120 for amplifying the TES signal are provided, connected to the control unit 90.

[0048] As described above, the DC / DC converter 100 connected to the control unit 90 of the first circuit unit C1 is for voltage matching, which increases or amplifies the magnitude of the TES signal applied to the respective electrodes M of the left and right earphones (RE, LE) to the same level when the user LS controls the intensity of the TES signal using the user interface 80. The TES signal generator 110 connected to the control unit 90 of the second circuit unit C2 generates the TES signal applied to the user LS, and the variable amplifier 120 amplifies this signal and transmits it to the earphone RE.

[0049] The variable amplifier 120 plays the role of switching the left and right pair of earphones (RE, LE) through the user LS's body when power is supplied via the link cable LC, which will be described later, and is controlled by the DC / DC converter 100.

[0050] In this configuration, the TES signal generation means and the TES signal intensity adjustment means are distributed between the first circuit section C1 and the second circuit section C2 of the separate earphones (RE,LE), respectively. This minimizes the size of each earphone RE,LE and maximizes the battery capacity, thereby increasing the lifespan.

[0051] The TES signal generated from the earphone RE only works when it conducts electricity through the user LS's ears, so a link cable LC is provided as a component of the assembly as a means of conducting electricity.

[0052] The link cable LC is a flexible wire equipped with cable terminals Tc at both ends, which serve as terminals for magnetic connection to the earphone terminals Te of the earphones (RE,LE). The earphones RE,LE and the link cable LC are electrically connected by magnetic force, and the user LS can easily detach the link cable LC from the earphones (RE,LE) by overcoming the magnetic force.

[0053] The link cable LC is electrically connected via the cable terminal Tc, and the output signals from the DC / DC converter 100 of the first circuit section C1 and the variable amplifier 120 of the second circuit section C2 are applied to the user LS's earphones RE and LE, respectively, to energize the human body.

[0054] The link cable LC is configured to overcome magnetic force and detach from the earphones (RE,LE) when the user LS is not using the TES treatment function, and is stored in the cable storage space CC provided in the charging cradle R. This configuration prevents the loss of the cable terminal Tc, and the charging cradle R can be configured in this way, or it can be provided as a separate pouch.

[0055] The charging terminal at the end of the charging slot R1 of the charging cradle R, and the charge terminal Tr, which is a terminal terminal through which ground and voltage (Vin) are rapidly transmitted, are provided as terminals for connecting to the earphone terminal Te, and similarly, a magnetic attachment type terminal configuration is preferred.

[0056] The cable terminal Tc of the link cable LC and the charge terminal Tr of the charging cradle R are connected to the earphone terminal Te of the earphones (RE, LE) by having a centrally protruding contact pin tp that is elastically released by an internal spring (not shown), and a ring-shaped contact piece tr that is electrically separated from this contact pin tp, thereby enabling current flow (the terminal configuration of the charge terminal Tr is the same in the drawings and is therefore not shown).

[0057] The operation of the fully wireless earphone assembly equipped with the TES treatment function of the present invention, configured as described above, will be explained.

[0058] (1) When user LS stores the earphones (RE,LE) of the present invention in the charging slot R1 of the charging cradle R without using them, the charging terminal Tr below the charging slot R1 and the earphone terminal Te of the earphones (RE,LE) enter a charging standby mode in which the voltage (Vin) of a battery (not shown) is connected to the terminal terminals inside the charging cradle R by the connection between the terminal terminals, and in this state, the TES therapeutic function of the earphones (RE,LE) is not activated due to the absence of the link cable LC (see Figure 6).

[0059] (2) When user LS is listening to music on a daily basis, the link cable LC is stored in the cable storage space CC of the charging cradle R and used by operating the earphones (RE, LE) in the normal listening routine (if the earphones are equipped with a function) or by operating them via the user interface 80.

[0060] (3) When user LS wants to use only the TES treatment function, or when user LS detaches the link cable LC from the cable storage space CC and attaches the magnet to the earphone terminal Te of the left and right earphones (RE,LE) in order to use the TES treatment function simultaneously while listening to healing music, an electrical connection is made between the terminals, and as selected by the user interface 80, the TES signal from the variable amplifier 120 that amplifies the TES signal of the TES signal generator 110 in the second circuit section C2 of the earphone (RE,LE) storage is applied to one ear of user LS and energized, and electrically connected to the DC / DC converter 100 of the first circuit section C1 of the other earphone (RE,LE), the TES signal is energized through both ears of user LS, and the treatment function is performed by applying low frequency to the human body (see Figures 5 and 7: In Figure 7, the buffer circuit 150 is to prevent damage to the circuit when the voltage level of the TES signal is higher than the set voltage of the control unit 90).

[0061] (4) When the user LS adjusts the intensity of the TES signal via the user interface 80, the DC / DC converter 100 of the first circuit unit C1 adjusts the intensity of the TES signal applied to both ears to be the same by matching it with the intensity of the TES signal from the second circuit unit C2, based on the signal adjusted by the control unit 90 of the second circuit unit C2 (see Figure 7).

[0062] Figure 8 shows the fully wireless earphone assembly A equipped with the TES treatment function of the present invention, configured as an actual circuit.

[0063] The Bluetooth® communication module 10 consisting of the first circuit section C1 and the second circuit section C2, along with the memory 15, decoding section 20, D / A converter 25, and audio amplification section 30, can be integrated into a single chip, while the TES signal generator 110 and variable amplifier 120 can be configured as analog circuits.

[0064] The configuration and operation of the present invention described above can be explained in more detail as follows.

[0065] The second circuit section C2, which is the other isolated circuit of the pair of earphones (RE,LE) separated into left and right, has a TES signal generator 50 for TES therapy connected to the control section 90 and a variable amplifier 60 to amplify the low-frequency signal, and the output of the variable amplifier will be determined by the voltage of the first circuit section C1.

[0066] Figure 7 shows how the TES signal voltage (intensity) is varied and output. The variable amplifier 120 switches the voltage of the variable DC / DC converter 100 to ON / OFF as controlled by the user and outputs it.

[0067] According to user operation, the output voltage of the TES signal output is determined by the voltage of the variable DC / DC converter 100. For example, if the voltage of the variable DC / DC converter 100 is 4V, the voltage level of the TES signal will be 4V, and if it is 20V, the voltage level of the TES treatment signal will be 20V.

[0068] The reason why the TES signal must be varied before output is that when the TES signal is applied to the user's LS (inner ear side), the intensity of the electrical stimulation felt varies from person to person, and the actual electrical stimulation felt by the user's LS differs depending on the state of the human body at the time of use (factors such as the condition and moisture level of the skin to which the electrodes touch, and the degree of contact with the skin).

[0069] Therefore, it is preferable to determine the output voltage of the TES signal by setting the minimum level to a very low level where no one feels much stimulation, and conversely, the maximum level to a voltage level where statistically everyone feels stimulation, and then setting the voltage values ​​between these levels in specific stages (10 stages (Level "1" to Level "10")), and then evenly distributing the output interval values ​​of the TES signal between each level.

[0070] When the link cable LC is disconnected from the earphones (RE,LE), the earphones (RE,LE) are used solely for the purpose of listening to sounds. In order to use the left and right earphones (RE,LE) as a therapeutic function (therapy mode) using TES signals, which is achieved by electrically connecting the left and right earphones (RE,LE) with the link cable LC attached, a means of determining whether the link cable LC is connected between the left and right earphones (RE,LE) is required.

[0071] This is because when the TES signal generator 110 and the variable DC / DC converter 100 operate with the left and right earphones (RE, LE) separated, unnecessary current consumption is naturally induced, shortening the battery life of the built-in batteries in the earphones RE and LE.

[0072] Figures 7 and 8 are block diagrams for detecting whether the left and right earphones (RE, LE) are connected by a link cable LC.

[0073] The role of the buffer circuit 150 is to prevent the voltage of the variable DC / DC converter 100 from becoming too high and damaging the entire circuit.

[0074] In Figure 8, the Det port from the Bluetooth® communication module 10 is configured to become LOW when an electrical voltage is output from the variable DC / DC converter 100 (i.e., when the link cable LC is connected to the earphones (RE,LE)), and to enter an audio listening-only mode when no voltage is applied (i.e., when the link cable LC is disconnected from the earphones (RE,LE)). This configuration allows for the determination of the connection status of the left and right earphones (RE,LE). Furthermore, even if the output voltage from the variable DC / DC converter 100 is very high, it is protected by the circuit protection function of the transistor (Q).

[0075] Although not a key technical aspect of the present invention, the charging cradle R, as a corresponding component of the earphone assembly A of the present invention, will be described in detail in conjunction with Figures 2 and 3.

[0076] Although various forms and configurations are possible, the charging cradle R is divided into a cable storage section RC, which has a cable storage space CC in the upper part that is a recessed part for storing the link cable LC, and an earphone charging section Re, which has a pair of long slit-shaped charging slots R1 for storing the earphones (RE, LE) in the lower part, and a charging terminal Tr provided below thereof. A cover plate C is provided that is independent of the cable storage section RC, and the cable storage section RC and the cover plate C are axially connected by a hinge shaft H, so that the cover plate C can be rotated relative to the cable storage section RC to open or close it, which was preferred in terms of convenience for storage and ease of carrying.

[0077] The cable storage section RC and the earphone charging section Re may be separate cylindrical bodies and can be stacked on top of each other as shown in the figure using a connecting guide G, or they may be composed of a pouch having the cable storage section RC as a separate storage pocket and a charging cradle (not shown).
