The small acoustic receiver is manufactured in a size and shape that can be worn in the ear or attached to the outer ear with a built-in small speaker, and the earphone or headphone that directly outputs the sound signal received from the sound reproducing apparatus such as MP3 to the outer ear. It is small in size and easy to use, so it has high value as a portable device.

However, in the conventional small acoustic receiver, the light and soft sounding plate (dia frame) is vibrated, so that the vibration force can not be felt as a tactile sense and can not transmit solid tremors such as bone conduction.

Accordingly, vibration earphones and headphones that support vibration have been developed. Conventional vibration earphones and headphones do not achieve the optimization of the vibration structure, and thus the proper performance is not supported by the output of the main body such as the MP3. As needed, an amplifier (Amplifier) was needed, and accordingly, additional power was needed, requiring an additional battery.

The present applicant has not only applied for a patent for a vibration unit with a structure optimized for vibration to solve this problem, but has also applied for a patent combining the optimized vibration unit with a general microspeaker unit. There is a market demand for simple and inexpensive acoustic receivers.

As described above, the present invention was created to solve the problems of conventional bodily vibration earphones or headphones in which vibration is weak and its utilization is limited, or additional costs such as amplifiers and batteries are generated. The aim is to provide a small tactile sound receiver that can be economically implemented.

In order to achieve the above technical problem, the present invention is a general sound, bone by vibrating the magnet in accordance with the acoustic signal received from the main body 105, which is a shape and can be inserted or attached to the outer ear or peripheral parts Vibration generating unit for generating the conductive sound and bodily vibration; A housing configured to protect the vibration generating unit therein; A connector part connected to the sound of the main body, a cord part connecting the connector part and the vibration generating part; A small haptic acoustic receiver comprising: a vibration generating unit comprising: a ring-shaped acoustic vibration coil positioned at a position receiving a magnetic force of a magnet about a magnet; A housing for fixing and supporting the acoustic vibration coil; A support member coupled to the magnet to support the magnet; A leaf spring coupled to the center of gravity of the magnet through the center of gravity of the supporting member on the opposite side of the magnet and having an outer edge fixed to the housing; It is configured to provide a small haptic acoustic receiver, characterized in that the magnet has a linear vibration structure in which the magnet vibrates linearly in accordance with the acoustic signal flowing into the coil.

In the small tactile acoustic receiver of the present invention, the vibration generating unit may extend the support member to fix the ring-shaped outer magnet on the top of the support member with the ring-shaped acoustic vibration coil interposed therebetween, or maximize the magnetic force for the vibration, or The support member may be extended to bend in the magnet direction, and a ring-shaped vibration coil may be positioned between the magnet and the support member to increase the magnetic force for vibration.

In addition, in the small tactile sound receiver of the present invention, it is possible to add an intermediate control unit for adjusting the magnitude of the sound signal input from the main body to the connector unit and the vibration generating unit, it is possible to replace the wired cord unit with a wireless such as Bluetooth It is characterized by.

Hereinafter, the technical spirit of the present invention will be described in detail with reference to the accompanying drawings.

The present invention can enjoy the haptic vibration effect felt at the output of the amplifier in the conventional analogous technology at low power even in a small haptic sound receiver, and provides a structure of earphones or headphones that implement general sound and bone conduction sound with a single vibration structure. It is done.

More specifically, by replacing the micro speaker used in the conventional small acoustic receiver with a linear vibration generating unit optimized for acoustic vibration, it is possible to realize bodily vibration, bone conduction, and general sound while maintaining compatibility with conventional devices.

1 illustrates an embodiment of a small tactile sound receiver according to the present invention, in which a vibration generating unit is positioned in place of an existing micro speaker.

In the present embodiment, a magnet is used as a vibrating weight as a bone conduction structure, but a dual structure including a cylindrical cylindrical magnet 41 and a ring-shaped outer magnet 42 spaced apart from the central magnet 41 are spaced apart from each other. Adopts magnet structure.

A ring-shaped acoustic vibration coil 43 is placed between the center magnet 41 and the outer magnet 42 to induce vibration of the magnet and fix the positions of the center magnet 41 and the outer magnet 42. The leaf spring 44 is coupled to the center of the yoke 58 to which the center magnet 41 is coupled to maximize the generation of the vibration width .

Since the structure of the vibration generating unit is excellent in vibration response, and exhibits sufficient vibration force even for a small sound signal, it can provide the effects of bone conduction and bodily vibration, and the power consumption is small, and the effect of miniaturization and cost reduction is great.

In order for the vibration of the vibration generating part to be transmitted to the outer ear, the vibration generating part must be fixed to the housing 1 of the vibration generating part inserted or attached to the outer ear.

The following describes the path in which the acoustic signal is realized as bodily vibration, bone conduction sound, and general sound.

The acoustic signal input from the main body is transmitted to the acoustic vibration coil through the code unit 51, and the acoustic vibration coil has a magnetic field according to the acoustic signal. The magnetic field of the acoustic vibration coil is changed according to the acoustic signal and affects the magnetic field of the adjacent magnet. Since the acoustic vibration coil is fixed to the housing, the magnet coupled to the leaf spring vibrates according to the acoustic signal.

When the magnet vibrates, the center-coupled leaf spring vibrates up and down according to the sound signal. At this time, the sound vibration is transmitted from the center of the leaf spring to the outside of the leaf spring to generate the bone conduction sound signal along the part connected to the housing. Will be. The housing is in contact with the outer ear and delivers the bone conduction sound. Due to the weight of the magnet, the outer ear feels the weight and the sense of sound can be felt by the tactile sensation due to the weight, so that the sensory sound is transmitted at the same time.

The present invention has a vibrating structure as well as bodily sensation as well as a bone conduction sound effect because it has an excellent vibration structure of the acoustic signal, this responsiveness is transmitted to the housing causing the vibration of the air in contact with the housing effect of the general sound of the air conduction type Also have. The diaphragm of film material used in general micro speaker is not vibrated, but plate spring and magnet, which are made of elastic metal, are vibrated, so the high frequency range is weaker than general micro speaker, but the material of plate spring and housing is high frequency. Selecting a material that responds to vibration can improve the sound range to a certain high range.

As shown in FIG. 3, the present invention includes an intermediate adjusting unit 6 between the main body and the intermediate adjusting unit 6 as a conventional volume control lever capable of adjusting the magnitude of the output signal. It includes.

When controlling the signal as shown in FIG. 4, if the intermediate amount control unit 6 is properly selected in the direction of increasing the volume, the current amount of the sound signal input to the vibration generating unit 3 is controlled to enjoy sound and bodily vibration. Can be.

According to the present invention, using a small bodily sensation vibration acoustic receiver optimized for vibration that can be inserted or attached to the outer ear or the periphery, it overcomes the limitations of the conventional sensation vibration receiver that requires an amplifier and a battery, and conducts bone conduction. And by providing general sound, you can enjoy the effects of high-quality bodily vibration acoustic receiver economically and conveniently.
