Description

Bone conduction application headset assembly {HEADSET USING BONE CONDUCTION APPICATION}

The present invention relates to a bone conduction application headset assembly, and more particularly, bone conduction suitable for use in application products that transmit acoustic signals and electrical signals for mental treatment selectively or together to the human auditory nerve in a bone conduction manner. It relates to the provision of improvements in the construction of headsets for applications.

BACKGROUND OF THE INVENTION [0002] In recent years, compared to the conventional method of hearing sound through air conduction by vibration of air to the eardrum of the human body, a mode of listening to sound by bone conduction has been widely spread.

'Bone conduction' is a method in which sound is transmitted to the cochlea by applying the physical vibration conductivity of the skull, and directly to the brain via the auditory nerve.

In the case of a headset using bone conduction, the advantage of enabling the prevention of accidents that may occur in an environment in which ambient sounds cannot be heard due to the wearing of the air conduction headset, and the occurrence of noise-induced hearing loss in the conventional method through air conduction It is useful in protecting the user's health, which can prevent back problems, and its spread is increasing.

In the case of a headset using bone conduction, a bone conduction unit is provided as a mechanical vibration generating means for transmitting sound and audio signals (hereinafter referred to as 'sound') to the auditory nerve of the human body. The bone conduction unit converts the electrical signal of the input sound into mechanical vibration, outputs it, and conducts it to the skin-skeletal system of the head of the human body. Conventional bone conduction units include frames, voice coils, magnets, It consists of a diaphragm, etc.

In particular, Korea Patent Publication No. 10-2015-0128401 of Patent Document 3, which is an extinct patent, discloses a bone conduction unit as shown in FIG. 9, and in this configuration, the magnet unit 20 driven by the coil 11 A mechanically connected diaphragm 40 and a protective cap 50 protecting the diaphragm 40 are disclosed, and this configuration is already known as one form of a general bone conduction unit.

The diaphragm of the bone conduction unit and the skin of the head of the human body must be closely connected, which is different from a general speaker-type headset in which sound can be transmitted even with some clearance.

In order to ensure close contact of the diaphragm of the bone conduction unit with the skin of the head of the human body, a structure that mechanically closes the diaphragm to the head of the human body, especially the skin of both ears, is required, and various structures have been devised in the past. .

The present invention provides a bone conduction application headset assembly optimized for realizing the above object, thereby ensuring smooth sound conduction and enabling use by users having various variable head body shapes. It is intended to provide a configuration with a low manufacturing cost by simplifying the configuration by not requiring a band or wire unit adjusting mechanism connecting a pair of combinations on both ears according to displacement.

Technologies that can be additionally considered along with the above viewpoints are,

The diaphragm of the bone conduction unit is made of conductive electrodes such as metal or carbon, or by adding a separate electrode body, it is possible to enjoy music on a regular basis and apply electrical stimulation to the electrodes when necessary, thereby providing a therapeutic effect as a special purpose. It is to configure a headset assembly for bone conduction application that can additionally emit.

In addition, a technology called transcutaneous electrical nerve stimulation (hereinafter referred to as 'TENSE') has been established as an applied technology due to the application of controlled electrical signals to the human body. It is known to have various effects such as treating pain by applying calculated electrical stimulation, and is being actively researched especially in Russia and the like.

It is accepted that the human body responds favorably to certain individual frequencies, and devices using TENS can produce a variety of effects by providing oscillating transcutaneous energy to electrodes placed over various parts of the human body. In addition, TENS is an application of electrical stimulation to the surface of the skin, mainly for pain relief.

TENS is applied and treated through external surface electrodes with several types of electrical waveforms characterized by frequency, pulse width, and amplitude, so it is pharmacological, non-invasive, non-toxic, has the advantage of having few contraindications, and is a treatment that has been identified. Its effects have been scientifically proven to improve depression, significantly improve sleep quality, relieve stress, increase concentration, and improve body mechanisms.

Conventionally, in Korea, a treatment device with a head-worn band for applying electric stimulation conducted from a chair and electrical equipment to the human body is called 'transcranial electrical stimulation therapy device' and is used in psychiatric departments of university hospitals. It is widely distributed and has an effect on the improvement of depression, but the clinical treatment device of the shape and configuration of this chair costs tens of thousands of won, and there is an inconvenience that can be applied only when requested.

Therefore, by providing a simple configuration and low-priced treatment device in the form of a popular type, it is a device that can be applied to various types of depression patients, increase the concentration of students studying, improve TIC disorders in children, and improve ADH. has been requested

Accordingly, the present applicant devised a 'bone conduction device with TENS function' of Patent No. 10-2194266 registered on December 16, 2020,

Korean Patent No. 10 - 2194266 Korean Patent Publication No. 10-2012-007920 Korean Patent Publication No. 10-2015-0128401

None.

As a source in a similar technical field discovered in relation to the present invention, there is Patent Document 2, and as shown in FIG. 1, Patent Document 2

In the back headband earphone composed of a headband worn on the head and a pair of earphones, the headband (4) is made of a rubber material and can be attached to any of the headbands (4) according to the size of the wearer's head. A length adjusting unit (3) whose length is stretched and contracted according to the size of the head by repeatedly folding the part of at least once is integrally formed, and the hair band (4) has a pair of length adjusting units (3) on both sides of the wearer's head. Is located or the length adjusting portion (3) is located at the back of the head (H) of the wearer, characterized in that the length adjusting portion (3) is made of a waveform or coil shape.

The configuration of this sailor's patent is different from that of the present invention in terms of technical ideas and operational effects, which will be described later, as it focuses on a configuration that can adjust the length in the configuration of a typical backhead earphone.

In order for a bone conduction application headset to function optimally, a configuration in which the diaphragm of the bone conduction unit must be in close contact with the skin on both ears of the head worn by the user is required, and conventional products have bone conduction for this purpose. The unit is separated from the main body of the headset, and a suspender, which is an earring part of an elastic elastic wire-shaped body, is formed between them, and the elasticity of the suspender makes the bone conduction unit part adhere to the skin of the human head.

The size of the head circumference of the head for each person has a very large range of displacement due to differences in genetic and growth environmental factors. Depending on the user, a space is induced between the head and the inner diameter of the headband (in the case of a user with a small head circumference).

In order to adjust this, it can be considered to provide the headband with various configurations, such as the above-mentioned line, which can be adjusted in length. When leaning on the member for adjusting the length, it is undesirable because it gives pressure to the head or causes discomfort.

Therefore, there is a demand for a bone conduction application headset assembly configured to be very simple without requiring a separate mechanical configuration for adjusting the length of the headband and at the same time not to apply mechanical pressure to the user's head. The present invention relates to the provision of such a configuration.

The provision of the bone conduction application headset assembly of the present invention makes it possible to use a number of users having various displaceable head body shapes, and additionally for adjusting the length of the headband connecting the units on both sides of the separate headset. Eliminates the need for instruments.

The configuration of the headset assembly for bone conduction application of the present invention is described in detail in comparison with conventional products.

Various types of bone conduction application headset assemblies have been released on the market, and most of the products have similar external and mechanical configurations, and the products with the configurations shown in FIGS. 4 and 5 will be described as representative.

Although the conventional headset OA is described, as in FIG. 4, since the headset OA is a left-right symmetrical unit, the configuration of both sides will be mixed and described.

A pair of main bodies 100 for the left and right of the user's head (H) in various box shapes molded entirely of synthetic resin materials are provided as housings capable of accommodating electrical members such as PCBs and batteries therein. .

As shown above the end of the main body 100,

When worn, a suspender 110, which is a tube made of an elastic synthetic resin material in a shape of a 'U' and acts as a hanging portion that is hung and suspended above the user's ear, is provided, and the inner tube body of the suspender 110 is shown. Wires for electrical wiring that are not used are laid out.

A unit body, which is a roughly box-shaped receptor, in which the bone conduction unit 130 for applying the above-described mechanical vibration is built-in at the front side (face side (F) on the user's head (H)) end of the suspender 110 ( 120) is integrally or separately fixed,

A diaphragm exposed from the bone conduction unit 130 accommodated inside the unit body 120 or a diaphragm portion covered with a separate protective plate (not shown) is exposed. A communication ball and a built-in microphone (not shown) for phone calls may be further provided.

Typically, the main button 121 for controlling the headset (OA) is provided as a touch button on the opposite side exposed to the unit body 120, and the main button 121 is provided on the main body 100. There is also

As described above, by separating and configuring the main body 100 and the unit body 120 to be connected as the suspender 110, the suspender 110, which is an elastic tube, is connected to the bone conduction unit 130 of the unit body 120. By elastically pushing the diaphragm 131 toward the skin side of the user's head H, an effect of enabling close connection can be obtained, and most commercially available bone conduction application headset assemblies employ this configuration.

The combination of a pair of left and right main body 100 - suspender 110 - unit body 130 as described above is connected or fixed at the rear end of the main body 100 with a band or wire in a substantially 'U' shape. It is connected as a connector 140 of the type.

In general, it is known statistically that the size and shape of the circumference of the head (H) of a user P of a person varies greatly from person to person, and therefore, a connector 140 of a roughly 'U' shape having a single inner diameter There was a problem in that it was difficult to absorb the deviations of all users with only one.

In the case of the bone conduction application headset assembly (OA) having the above conventional configuration, the connector 140 is provided as an elastic band or elastic wire having a single inner diameter to be worn around the user's head,

In order to absorb the user (P) with the circumference of various head shapes (H, H') according to genetic and growth environmental factors, the circumference of the head (H) of the standard user (P) is slightly larger than the size of the head (H) manufactured, and when the user (P) leans the head (H) against the chair back or headrest while listening to music, the pressure or pain due to the elasticity of the connector 140 itself is applied to the head (H) of the user (P). However, due to the excessive length of the connector 140, the suspender 110 is detached from the ear E of the user P.

In addition, if the shape of the head (H) is atypical (for example, a so-called "chanjanggu") due to genetic and growth environmental factors, it is greatly deviated from the displacement deviation of the size of the head (H), making it impossible to wear it at all. There is also a problem, and in the case of women with long hair, due to the presence of considerable volume of hair, they also have an important problem that cannot be worn.

Considering the problems of the conventional configuration as described above, the bone conduction application headset assembly of the present invention provides a configuration optimized for sound listening by changing the shape and design of the mechanical configuration, and additionally functions as a treatment device using TENS let it do

The basic technical idea of the bone conduction application headset assembly of the present invention will be described below.

From a statistical point of view, it is necessary to determine the length and shape of the optimized connector according to the user.

Figure 2 shows the distribution of head circumference size according to individual Koreans between the ages of 20 and 29, and it can be seen that the measured values are distributed according to each quantile of the statistical object, and the difference between the values for each quantile is large. Figure 3 shows the distribution of the size of the neck circumference according to individual people, and it can be seen that the displacement deviation is very small because the measured values are concentrated in the 5th quartile according to each statistical target quartile.

The fact that can be proven through this is that the size of the neck circumference compared to the size of the head circumference of a person exists within a fairly limited similar range.

Therefore, in configuring the bone conduction application headset assembly,

The above-described connector 140 is not provided based on the size of the circumference of the head (H) of the user P, but the geometrical configuration provided based on the size of the circumference of the neck (N) is a single size (length) It is possible to minimize the options of the connector 240 required by enabling a number of users to satisfactorily use the connector 240 of the connector 240 to be seated in the neck portion N of the user P. It can be seen that this is preferable.

The bone conduction headset assembly (NA) of the present invention is described through FIGS. 6 to 8, but as shown in the drawings, the headset assembly (A) is also a left-right symmetrical unit, so the configuration of both sides will be mixed and described.

The bone conduction headset assembly (NA) of the present invention is also entirely molded of a synthetic resin material, and a pair of main bodies 200 for the left and right sides of the head (H) of the user (P) in various box shapes are inside a PCB, battery, etc. It is provided as a receiving box capable of accommodating the electrical member of the.

On the upper side of the end of the main body 200, a suspender 210, which is a tubular body such as a synthetic resin material of elasticity in a shape of a 'U', acting as a hanging part that is suspended by being caught in the ear (E) of the user P when worn. , A unit body, which is a roughly box-shaped receptor in which the bone conduction unit 230, in which the diaphragm portion 233 is exposed at the end of the front side (the face side (F) on the user's head (H)) of the suspender 210, is built-in (220);

It has the same mechanical configuration with In the drawing, 236 is a main button for control, and 238 is a through hole for communication.

As shown in FIG. 6 below, the main body 200 of the bone conduction application headset assembly (NA) devised in the present invention

When worn, a liner shape with a relatively long length L in the direction of the longitudinal axis C extending downward from the rear R of the ear E of the user P, and the approximate length of a rectangle, lozenge, or long radius. It is constituted as a box-shaped body such as an elongated ellipsoid.

The usefulness of the main body 200 configured in a substantially rectangular liner shape having a longer length (vertical length) in the longitudinal axis (C) direction than the length (horizontal length) in the transverse axis direction on the box body is as follows.

The wearing position of the connector 240, which is a band or wire in a roughly 'U' shape extending integrally or replaceably from the free end of the main body 200 (ie, the opposite side of the suspender 210 wearing part) to the user's rear neck This is because it is easy to position the inner diameter portion R of the connector 240 seated on the rear neck portion N by moving it to the (N) side as much as possible.

A band or wire-shaped connector 240 connecting a pair of left and right main bodies 200 - suspender 210 - unit body 220 is experimentally measured from the longitudinal longitudinal axis C of the main body 200. It is provided between a pair of main bodies 200 to have a determined wearing inclination angle (a), and the inner diameter portion (R) of the approximately semicircular connector 40 is tangent to the middle-lower portion of the user's rear neck portion (N). Sexual connection and positioning.

The diameter of the inner diameter (R) of the connector 240 is selected and designed at a value slightly larger than the above-mentioned Korean standard neck circumference, so that the remainder between the user's neck (N) and the inner diameter (R) of the connector 240 A space M may be provided.

As the provision of the remaining space M, the user P having the circumference size of the neck N of various possible displacements can be used as a connector 240 having a single inner diameter. This minimizes the need for replacement of the connector 240.

Despite the existence of the remaining space M of the connector 240 described above, even when the user P leans his head on the headrest of a chair (not shown), the neck portion N does not contact the headrest, A foreign body sensation of the head (H) or a pressure feeling to the head (H) according to the conventional configuration has a useful action and effect.

As described above, the attachment of the diaphragm 233 of the bone conduction unit 230 to both ears E of the head H of the user P is a suspender, which is an elastic tube that is mechanically elastic as a connecting tube. Since it is made by 210, the user P's close contact at the neck N has no technical and functional meaning.

In the above, if the length (L) of the longitudinal axis (C) direction of the main body 200 is not long,

Since the connection point at which the connector 240 extending from the free end of the main body 200 starts is located at the upper end of the head H of the user P, the connector 240 is positioned at the neck N. The wearing inclination angle (a) has to be a considerable acute angle,

This is because the connectivity to the rear neck portion N of the user P is reduced, and the fit is also poor, and stable connection is difficult.

In the above, the length (L) of the main body 200 in the direction of the longitudinal axis (C) and the angle of the wearing inclination angle (a) will be experimentally determined variables based on statistical data, and various design-defining numerical values are selected. It can be, so it is not mentioned in the present invention.

Another usefulness of the configuration of the headset assembly for bone conduction application of the present invention is as follows.

Statistically, the distance (k) between the upper end point (e) of the ear (E) of the user (P), which is the wearing position of the suspender 210, and the neck starting point (f), where the neck (N) starts, is There is not much difference between Westerners.

Therefore, in the case of the headset (NA) of the present invention having an extension of the length of the main body 200 in the direction of the longitudinal axis (C) and a wearing inclination angle (a) while extending from the free end of the main body 200,

With very few exceptions to applicable targets, the use of the majority of the user (P) layer is possible, so even in the case of export of the product according to the present invention, most of the users (P) are sold as a single connector 240 Therefore, it is possible to remove regional restrictions along with the body displacement of the user P.

As described above, the connector 240 fixed to the end of the main body 200 having a long liner shape having a length L in the longitudinal axis C direction while having a wearing inclination angle a has a variety of neck circumferences. It can absorb the displacement range of the user (P) of the size, and the connector 240 is stably positioned at the neck (N) so that even women with long hair can wear it on the neck (N) regardless of the volume of the hair. Thus, user-facing limitations are largely removed.

In addition to the configuration above, as described above, the diaphragm 233 of the bone conduction unit 230 is composed of a conductive electrode body (not shown) insulated from an electrical terminal for a sound signal, or a separate electrode body. It is composed by adding

It is also useful for bone conduction application headsets that can simultaneously or selectively perform normal sound listening and TENS treatment by transmitting the controlled TENS signal of the present inventor's pre-registered patent as an electrical signal to this electrode body. can be applied appropriately.
