Description

TECHNICAL FIELD [0001] The present invention relates to a terminal for providing a realistic sound using a vibration module,

BACKGROUND OF THE INVENTION 1. Field of the Invention [0001] The present invention relates to a terminal including a vibration module, and more particularly, to a terminal including a vibration module that enables more realistic music to be enjoyed through vibration.

When a CD (Compact Disc) was first introduced, it was appreciated that the LP (Long Playing record) was reproduced with clean and clear sound without white noise caused by dust when reproducing the LP (Long Playing record), but lacked richness and dryness somewhere. This is because the CD is a sound source that has been compressed and cut off, not just the analog sound. However, CD is much more popular than LP, and LP is gradually disappearing.

Since the era of information communication has come, the sound source has been further compressed to meet the small storage space and the initial network speed, and the sound quality has been reduced by daringly deleting over a certain frequency band compared with the original sound. However, (MPEG Audio Layer-3) file, pushing even CD and MP3 sound source became the mainstream of digital sound source.

However, it is now time consuming and the storage technology has developed so much that the gigabyte of the USB memory has become the basis, and the terabyte of the hard disk installed in the PC is used.

As the constraints on the storage space were greatly reduced and the performance of the sound device increased, the need for high sound quality began to arise. The thirst for high-quality sound was not satisfied with low-compression MP3 files, which tend to favor sound quality even though the file capacity is somewhat larger. Music enthusiasts have begun to want better sound quality than MP3, and lossless sound sources are starting to gain popularity.

In this way, it is gradually becoming known to the public that a mastering quality sound (MQS) is a lossless sound source that gives the same quality of mastering sound recording in the studio. I have been able to play these lossless sound sources in professional sound equipment and PC, but most of them have not been supported in portable devices. Iriver, which is famous as an MP3 player in Korea, introduced portable devices that can play lossless sound sources, And started exploring the device market. Since then, the interest in lossless sound sources has been increasing as the launch of high-end smartphones that can play lossless sound sources from a variety of mobile phone manufacturers.

However, the high-quality sound of a lossless sound source is half the effect if the earphone or headphone being used does not sound properly, and the sound quality difference above 192 KHz is no longer different.

Therefore, the need for high-quality and basic elements has emerged, and interest in 4D effects (visual, auditory, tactile, directing, lighting) has been increasing to enable more enjoyment of music other than high-quality sound.

Modern smart devices have built-in vibration generators and generate vibrations in the incoming signal, thereby notifying the user of the incoming call. As such, the smart device includes a function for reproducing the voice. At this time, if the vibration device built in the smart device is used, it is possible to provide an effect of enjoying music more realistically. However, the conventional vibrating device is designed to generate only regular vibrations, so that there are limitations in generating various vibrating effects that allow music to be enjoyed more realistically.

In order to solve the problems of the related art as described above, the present invention proposes a terminal including a vibration module for enjoying more realistic music through vibration.

However, the present invention is not limited to the embodiments described below, but may be embodied in various forms. In the following description, it is assumed that a part is connected to another part, But also includes a case in which other elements are electrically connected to each other in the middle thereof. In the drawings, parts not relating to the present invention are omitted for clarity of description, and like parts are denoted by the same reference numerals throughout the specification.

Hereinafter, the present invention will be described with reference to the accompanying drawings.

1 is a block diagram of a terminal according to an embodiment of the present invention.

The terminal 100 of the present invention may include a sound source input unit 110, a sound source output unit 120, an extraction unit 130, a vibration module 140, and a controller 150.

The terminal 100 may include various playback devices such as a portable audio player such as an MP3 player, a CD player, or various end devices (PMP, PDA, mobile phone, smart phone) having an audio output.

The sound source input unit 110 receives a sound source to be reproduced in the music reproduction apparatus. The input of the sound source may be input from a separate memory unit (not shown) in which the sound source is stored, or a sound source that is streamed through the communication module (not shown).

The sound source output unit 120 outputs the input sound source to a speaker, a headphone, an earphone, etc. connected to the sound source output unit 120.

The extraction unit 130 may extract the vibration control signal using the frequency information of the low frequency band of the input sound source or extract the vibration control signal inserted in advance into the input sound source by a tag method or the like.

More specifically, the extracting unit 130 first confirms whether a vibration control signal is inserted into the sound source, and if there is no inserted vibration control signal, the frequency of the low frequency band of the sound source through a low pass filter (LPF) Information is analyzed to extract a vibration control signal. Since the higher the frequency is, the higher the frequency is, the higher the frequency is, the higher the frequency is. The extracting unit 130 extracts information that is effective for the user to feel the sound as vibration in consideration of a frequency of at least a certain size in the frequency waveform, energy at each frequency, sharpness and the like. For example, a vibration control signal is extracted that allows the user to feel the rhythmic feel of the tone source.

The vibration control signal may include at least one of vibration intensity, vibration length, and vibration effect information. This will be described in more detail later.

The vibration module 140 generates vibration corresponding to the sound source according to the vibration control signal.

2 is an exploded perspective view of a vibration module according to an embodiment of the present invention.

The vibration module 140 includes housings 11a and 11b that accommodate components, coils 13 accommodated in the housings 11a and 11b, and coils 13 that are accommodated in the coils 13 and move up and down by the magnetic force of the coils 13. [ A vibrating body 15 to which the magnet 15a and the weight 15b are coupled and a diaphragm 10a or 10b provided in the portion where the vibrating body 15 is collided by the up and down movements of the vibrating body 15 in the housings 11a and 11b do.

The housings 11a and 11b may include a housing main body 11a having a housing shape and a lid 11a for blocking an opening portion of the housing main body 11a. At this time, the coupling between the housing main body 11a and the lid 11b can be achieved by curing as an embodiment. That is, a step is formed in the inner peripheral portion of the opening of the housing main body 11a, the lid 11b is seated on the step, and the peripheral edge of the opening of the housing main body 11a is bent toward the lid 11b, The lid 11b can be press-coupled.

The housing main body 11a or the lid 11b may be provided with a printed circuit board to which external connection terminals to which the tip end of the coil 13 is drawn out and brazed are coupled. A current corresponding to the vibration frequency information supplied from the terminal is applied to the coil 14 through the flexible circuit board so that the magnetic field is caused to react with the electric field in which the flow of the signal is alternated by the Fleming's left- do.

The vibrating body (15) vibrates up and down by the magnetic force generated by the current applied to the coil (14). The magnet 15a of the vibrating body 15 may be a permanent magnet. The weight 15b may be a non-magnetic material such as tungsten. The tungsten has a specific gravity higher than that of the magnet 15a, so that the weight can be significantly increased even in the same volume. When the weight is increased, the vibration force during vibration can be expected, and the weight 15b can be variously adjusted according to the vibration effect desired by the user.

The upper diaphragm 10a and the lower diaphragm 10b may be provided at portions where the vibration of the vibrating body 15 of the housing 11 is caused by the up-and-down movement. Therefore, the diaphragms 10a and 10b can provide an additional vibration effect as the vibrating body 15 collides with the diaphragms 10a and 10b in addition to the vibrating effect caused by the up-and-down movement of the vibrating body 15. [ The diaphragms 10a and 10b may have a thin film shape that collides with the vibrating body 15 in order to constitute a vibration effect and may be a drum when the vibrating body 15 collides with the vibrating plates 10a and 10b, May be formed in various thicknesses and materials so as to generate vibrations that are generated when the vibration is applied. In addition, since the upper diaphragm 10a and the lower diaphragm 10b are formed to have different thicknesses, different vibration effects can be generated regularly.

3 is a cross-sectional view of a vibration module according to an embodiment of the present invention.

Referring to Fig. 3 (a), if the N pole is located above the magnet 15a and the S pole is located below the magnet 15a, then the direction of the magnetic field will be from the N pole to the S pole .

When a current flows in the coil 13 in the clockwise direction in the state where the magnetic field is formed as described above, the vibrating body 15 moves upward as shown in FIG. 3 (b) The vibrating body 15 moves downward as shown in FIG. 3 (c), and vibrates continuously in this state.

At this time, a vibrating effect generated when the drum or the drum is hit through the collision between the upper diaphragm 10a and the lower diaphragm 10b during up-down movement, i.e., vibration, of the vibrating body 15 may occur.

4, one or more protrusions 15c may be formed on the surface of the weight 15b which collides with the diaphragms 10a and 10b, and the protrusions 15c It is possible to generate a vibration effect such as to strike a drum or a drum more realistic when the protrusion 15c collides with the diaphragms 10a and 10b.

According to an embodiment of the present invention, when the current flows in the clockwise direction in the coil 13 by varying the thicknesses of the upper diaphragm 10a and the lower diaphragm 10b, and when a current flows in the counterclockwise direction So that different vibration effects can be generated. For example, when the vibrating body 15 collides with the upper diaphragm 10a, the vibrating effect of the " thumping " vibrates when the upper diaphragm 10a and the lower diaphragm 10b collide with the lower diaphragm 10b. The thickness of the lower diaphragm 10a may be adjusted.

According to the embodiment of the present invention, the thicknesses of the upper surface 11a and the lower surface 11b of the housing are different from each other, except for the configuration of the diaphragms 10a and 10b in the vibration module, It may be possible to produce different vibration effects when colliding with the upper surface 11a or the lower surface 11b.

The control unit 150 generates a vibration effect that enables the user to experience the sound source more realistically by driving the vibration module 140 using the vibration control signal extracted by the extraction unit 130. [ As a result, the user can experience the same experience as listening to a sound source at an actual performance site.

The plurality of vibration effects generated in the vibration module 140 may be generated through direction control of the current applied to the coil 13. [ To this end, the vibration effect information included in the vibration control signal may include current direction information applied to the coil.

The current direction information is a time series of at least one of clockwise current supply information (hereinafter referred to as A), current supply cutoff information (hereinafter referred to as B), and counterclockwise current supply information (hereinafter referred to as C) Means combination information.

For example, when the vibrating body 15 moves upward due to the supply of the current in the clockwise direction for the sake of convenience of explanation, the vibration effect of the "kick" occurs, If there is a collision, it is assumed that a "paired" vibration effect occurs.

At this time, when an effect such as a "thumping pulse" is required as a result of frequency analysis of a sound source, current direction information such as ABAC can be applied to the vibration module 140. [

Further, the vibration effect information may further include current intensity information.

The intensity information of the current includes first intensity information (hereinafter referred to as X) and second intensity information (hereinafter referred to as Y), and the first intensity information indicates that the vibrating body 15 is raised or lowered, The second intensity information indicates that the vibrating body 15 is in contact with the upper surface of the upper vibrating plate 10a or the lower vibrating plate 10b Refers to intensity information that can rise or fall without touching one surface.

Therefore, when the current direction information is A and the current intensity information is X, the vibrating body 15 moves upward and collides with the upper vibrating plate 10a. When the current direction information is A and the current intensity information is Y, The body 15 moves upward but does not collide with the upper diaphragm 10a.

Hereinafter, A (X) is information for supplying a current in a clockwise direction to a first intensity, C (X) is information for supplying a current in a counterclockwise direction to a first intensity, A (Y) Direction, C (X) means information supplying current in a counterclockwise direction to the second intensity.

In this case, when the vibration module 140 is driven by A (Y) C (X), the vibrating body 15 moves upward and moves downward before colliding with the upper vibrating plate 10a, 10b. Therefore, as compared with the case where the vibrating module 140 is driven only by C (X), the distance until the vibrating body 15 collides with the lower vibrating plate 10b becomes longer, . In addition, when the vibration module 140 is driven by C (Y) A (X), it is possible to generate a vibration effect of "bump" have.

Table 1 below shows an example of combination information according to various vibration effects.

Accordingly, the extracting unit 130 generates a vibration control signal including the vibration effect information based on Table 1, which enables the sound source to be enjoyed realistically by analyzing the sound source, and the controller 150 uses the vibration control signal By driving the vibration module, various vibration effects can be generated in the vibration module.

As described above, the present invention enables various vibration effects according to a rhythm of a music to be transmitted through a tactile sensation in a terminal including a vibration module capable of reproducing various music, so that the music can be appreciated in three dimensions.
