Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to, for example, mounting an electromechanical converter inside a housing of a portable telephone or a small terminal of a mobile communication device, for example, to notify a carrier of an incoming call, or to distribute music. The present invention relates to a mobile communication device of a bodily sensation system capable of enjoying a feeling of bass and rhythm when receiving.

[0002]

2. Description of the Related Art In the above-mentioned applications, a sounding body for a small terminal of a mobile communication device including a portable telephone device generally uses an ultra-small electroacoustic transducer. For devices such as mobile phones that do not allow ringtones to be heard around, it is equipped with an electromechanical transducer for incoming signals in addition to an electroacoustic transducer for call signals. Some devices have a function of notifying an incoming call. In such a case, an eccentric drive motor is generally used because the electromechanical converter needs to be small.

[0003]

In the current situation of the above-mentioned conventional small terminal of a mobile communication device, when the terminal listens to music distributed by music distribution, the reproduced sound of the ultra-small electroacoustic transducer is not used. There was a drawback that sound quality could not be sufficiently satisfied. In addition, there is a problem to be solved that it is desirable to have a sensation close to the sound sensation felt on a daily basis even when a mobile phone is used to hear a normal sound.

Accordingly, an object of the present invention is to solve the problem of the sound source of such a conventional small terminal of a mobile communication device. It is very small, lightweight, inexpensive, easy to use, and has a complete notification function based on incoming signals. The mobile communication of the bodily sensation method in which a satisfactory ultra-low pitch can be obtained without giving a fatigue or an uncomfortable feeling even when used for a long time during work by giving a mechanical vibration of a low frequency to the labor shrine. Is to offer a machine.

[0005]

Means for Solving the Problems The configuration of the mobile communication device according to the present invention, which has been adopted to achieve the above object, will be described with reference to the reference numerals used in the embodiments. At least one vibrator 1 for converting the output received information signal into bodily-acoustic vibration is mounted on a casing 2 of the mobile communication device via an elastic body 3 and carries the mobile communication device. In addition, the configuration is such that the user uses the low-frequency component of the received information to be sensed through bodily sensations.

[0006]

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS The present invention has the above-described configuration. In implementing such a sensation-type mobile communication device, the vibrator 1 is provided with a movable magnet type electric communication device. It is preferable to use a mechanical vibration transducer because it has a simple structure, can be easily miniaturized, and is inexpensive and has a long life.
It is needless to say that not only the above-described movable magnet type but also other types of electromechanical vibration converters such as a movable coil type, an electromagnetic type, and a linear motor type may be used as the vibrator 1.

[0007] At least one such vibrator 1 is used in the mobile communication device of the sensation system, the housing 2 is used in the portable telephone handset, and a mobile device such as a portable radio receiver is used. In the case of a small terminal of a body communication device, it is similarly attached to the housing 2. In this case, the vibrator 1 may be directly attached to each of the casings 2, but by attaching the vibrator 1 via the elastic body 3, the sensitivity to the casing vibration can be increased. In this case, it is effective to mount the vibrator 1 so that the vibration direction is perpendicular to the longitudinal direction of the receiver, in order to further increase the sensitivity. The elastic body 3 may use a spring, rubber, foamed resin, or the like. Note that a low-pass filter may be interposed between the vibrator 1 and a receiving circuit of a mobile communication device that supplies a received information signal to the vibrator 1 as necessary.

A vibration system having one degree of freedom is formed by the vibrator 1 and the elastic body 3, and the resonance frequency of the resonance system is 30 to 50H.
Suitably, it is in the range of about z. In the case where the vibrator itself has a unique resonance frequency like a movable magnet type, when the resonance frequency of the vibrator itself and the resonance frequency of the resonance system including the vibrator 1 and the elastic body 3 are combined, furthermore, It is effective. Conversely, by making these two frequencies different, the reproduction frequency band can be expanded.
Further, even if a plurality of vibrators are attached to the housing 2 at different resonance frequencies, the reproduction band can be expanded.

In general, the meridians in the human body extend from the palm to the soles of the body, and the point at which the meridians concentrate is generally called a "pot". Is called Lagu, located in the center of the palm. The present inventor focuses on a phenomenon in which a significant acupressure effect is obtained by pressing the “pot”, and applies this phenomenon to the “pot” where the most effective meridians are concentrated, that is, the labor located at the center of the palm. I discovered that by giving the shrine bass vibrations, an excellent bass feeling could be obtained. Based on this fact, by mounting the above-described vibrator 1 on a handset or a small terminal of a mobile communication device that is always in contact with the palm, the sensible acoustic vibration can be effectively transmitted to the human body, and the music distribution can be received. It is characterized in that an effect on bass feeling and rhythm feeling can be obtained. In addition, the low-frequency sound reproducing apparatus of the bodily sensation system is not limited to music, and it can be effectively used even with software that produces sounds such as games, and it is needless to say that music can be more enjoyably listened to even with a limited device such as a telephone. .

Further, as described above, at the time of a call signal, it is possible to notify the other person by vibrating without being heard of the call sound. This can be a constant frequency signal,
It can also be linked to ringtones. In particular, even when listening to the music signal distributed to the telephone using the earphone, the effect becomes more remarkable since the telephone handset is always in contact with the labor hall by holding the telephone body in hand. . Further, as another application example of the present invention, even if the small terminal of the mobile communication device is a dedicated device for listening to music, or a game dedicated device for listening to the sound effect thereof. The above-mentioned effects are obtained.

It is supported so as to be able to vibrate in a direction to form a vibration system.

In this case, by increasing the lengths of the springs 14, 14, the resonance frequency of the vibration system is lowered, and vibration with a large amplitude is possible, thereby increasing the sense of bass. The length of the coil 11 in the axial direction is such that the portion of the magnet system spacer 13 at the required maximum amplitude, that is, the portion of the S pole of the magnet whose magnetic lines of force radially interlink with the coil 11 is The S and N poles of each magnet are connected so that they do not come off and that both ends of the magnet system, that is, the N pole portions of the magnets 12 and 12 do not enter the inside of the coil 11. The end of the coil 11 is set at an intermediate position.

FIG. 3 shows a moving coil type electromechanical vibration converter as another example of the vibrator 1. In the structure, a cylindrical movable coil 16 is attached to the center of the bottom of the housing 2, and a magnetic circuit 17 having a radial magnetic field 17 a is attached to an upper part of a case 19 so as to be vibrated by a damper 18. The movable coil 16 is located in a radial magnetic field 17a of a magnetic circuit 17, and generates a driving force by applying an audio current. In order to attach the vibrator of this type to the housing 2 of the receiver, the foamed resin may be attached as the elastic body 3, for example, between the front and rear walls of the housing 2.

[0015] As still another embodiment, when the mobile communication device is a portable radio receiver, a music signal dedicated device that operates by distributing a music signal, or a game software signal that operates by distributing a game software signal Regarding the embodiment in the case of a dedicated machine, the mounting structure of the vibrator 1 in the small terminal of each embodiment is basically not different from the case of the mobile phone, so that the illustration is omitted.

The embodiments which are considered to be representative of the present invention have been described above. However, the present invention is not necessarily limited to the structures of the embodiments, but has the above-mentioned constitutional requirements according to the present invention, and The present invention achieves the object of the present invention and can be appropriately modified and implemented within the range having the following effects.

[0017]

As is clear from the above description, the mobile communication device of the sensation system according to the present invention incorporates a small-sized vibrator for reproducing low-pitched sound into a small terminal of the communication device. Because it is used as a mechanical vibration and low-frequency reproduction device of the bodily sensation type during use, it is very small, lightweight, inexpensive, and easy to use. By feeling, even a limited device such as a telephone can listen to music more enjoyably.

The present invention is effective not only for music but also for simply listening to sound. Further, a vibration is generated at the time of the call signal, so that the notification can be made without being heard by others. Alternatively, it can be used together with the sounding body and linked with the incoming melody. In particular, the vibration is amplified when the vibration exciter is attached to a telephone case, so that the vibrator can be made smaller. When in use, it comes into contact with the palm of the labor shrine, so that each of the above-mentioned effects can be obtained with a minute vibration, which also has the effect of contributing to downsizing of the vibrator and power saving.
