Is.

First, the multifunctional vibration actuator 1 shown in FIG.
6 will be described. As shown in FIG. 2, the multifunctional vibration actuator 16 includes a coil 1, a magnetic circuit having a gap composed of a yoke 1, a permanent magnet 2 and a plate 3, and a coil 6.
A vibrating body 5 having the coil 6 fixed at a predetermined position, a vibration transmitting portion 8 for transmitting vibration to the outside, and a magnetic circuit are flexibly supported.
The electroacoustic transducer is composed of the suspension 4 fixed to the vibration transmitting portion 8. When a drive current is applied to the coil 6, the magnetic circuit and the vibrating body 5 to which the coil 6 is fixed vibrate vertically in the axial direction of the central axis 7. At this time, the multifunctional vibration actuator can use various functions such as a receiver, a speaker, and a vibe motor by controlling an input signal such as a voltage and a waveform, an output frequency range, and the like, and considering an attaching direction.

Since the usage examples of the mobile communication devices shown in FIGS. 1 and 3 are the same, the multifunctional vibration actuator 1 is used.
A two-fold type mobile communication device equipped with No. 6 will be described.

In FIG. 1 (a), the multifunctional vibration actuator 16 is provided on the portion of the receiver 20 (the rear surface of the display 17) of FIG. 4 (a) which is the most standard arrangement of mobile communication equipment such as a mobile phone. It is installed. The mobile communication device of the present invention is configured to switch between the receiver, the speaker, and the buzzer mode by opening and closing the mobile communication device.

In receiver mode, the conventional receiver 20
Similarly, as shown in FIG. 1B, the mobile communication device 1
8 is used in an open state, and voice is output from one side of the multifunctional vibration actuator 16.

Further, as shown in FIG. 1 (c), in the speaker mode, the mobile communication device 18 is used in a closed state, and a ring tone such as a voice or a melody is output from the opposite surface in the receiver mode. ing. At this time, by controlling the input signal such as voltage and waveform, and the output frequency range,
The speaker mode is switched. Since the multifunctional vibration actuator 16 emits sound to the outside regardless of the open / closed state, the mobile communication device 18 of the two-fold type is used.
When it is used for, the circuit is controlled so that the function of the speaker does not work in the opened state for safety.

The vibrate mode is used regardless of the open / closed state of the mobile communication device 18, as shown in FIG. 1 (d). In addition, since the multifunctional vibration actuator 16 is attached to a place outside the center of gravity of the mobile communication device 18, the mobile communication device 18 can be easily vibrated.

As described above, even if the three individual components of the receiver, the speaker, and the vibe motor mounted on the mobile communication device are replaced with a multifunctional vibration actuator, various modes can be handled equally. Also, by replacing the three individual parts with a multifunctional vibration actuator, the mounting volume on the back side of the display has been reduced due to thinning, and the individual parts near the key buttons have been made smaller, resulting in a thin and lightweight mobile communication device. Even if there is a need for downsizing and downsizing, it is possible to meet the requirements for sufficient downsizing in terms of volume, weight, height, etc.

[0020]

As described above, according to the present invention,
It has been possible to provide a mobile communication device capable of saving internal space and downsizing components, and further capable of using the same voice and vibration output functions as in the past.
