In addition, it is possible to provide a function as a diaphragm for the purpose of bodily sensation.

  FIG. 2 shows a configuration example in which two vibrating portions of a speaker are attached to the side surface of the mobile phone 100. The vibration part 10 and the vibration part 11 in FIG. 2 correspond to the vibration part a (50) and the vibration part b (51) in FIG. In addition, the attachment position of these vibration parts 10 and the vibration parts 11 may be anywhere as long as it is a substantially planar vibration surface (flat panel) 15 having a certain area on the housing.

  An operation example will be described by taking the mobile phone 100 of FIG. 2 as an example. In the following description, an arbitrary position on the casing of the mobile phone 100 is defined as a point 12. A circuit operation for controlling the vibration amount of the arbitrary point 12 will be described with reference to FIG. For convenience of explanation, signals input to audio ch1 and audio ch2 in FIG. 1 are monaural signals.

  As data held in the memory 21, a set value that is an in-phase signal with a phase difference of zero from the signal output from ch 1 and a set value that is opposite in phase are written at an arbitrary point 12 in FIG. In addition, as the adjustment value of the signal amplifying unit, a necessary number of stages are written in the speaker adjustment level value of the mobile phone 100.

Further, by setting fine phase control values and volume values in the memory 21 and controlling them by the CPU 20, vibration control of a plurality of points on the housing can be performed. This makes it possible to diversify operations. Specific examples of this diversification are listed below.

(1) Position movement of a resonance point (a resonance point generated by a change in vibration specifications of a plurality of diaphragms).
The position movement of the resonance point includes various fluctuations / changes such as position movement such as front / rear, left / right, rotation, etc., vibration strength, area of the resonance point, meandering / backward movement of the resonance point position, etc. Shall be.

(2) Time-dependent change of vibration (vibration including magnitude and frequency) specifications.

According to the above conditions, the contents of incoming calls can be identified even if both hands are blocked, and the above identification can be performed even while driving a car or operating a bicycle. Furthermore, the above identification is possible without being noticed by a person in the vicinity.

In the above-described embodiment, the attachment positions of the two vibration parts 10 and the vibration parts 11 are on both ends of a plane having a certain area on the housing. However, these vibration parts are not limited to two, and there are other problems such as mounting area. However, the number of vibration parts is three or more, and three points on the triangular position and four on the square position with respect to the vibration surface. A point etc. is good. With this configuration, the position of the resonance point can be diversified from one dimension to a secondary source.
Further, the attachment positions of the vibration part 10 and the vibration part 11 may be any plane as long as they are on the housing and have a certain area. For example, a housing panel at the back is used.
In the above embodiment, the attachment positions of the vibration unit 10 and the vibration unit 11 are on the housing and are two points, and therefore, the resonance point is on a straight line connecting the two points. On the other hand, when the attachment position of the vibration part is set to three or more points, the resonance point can be selectively set and moved in a plane. This makes it easy to recognize and identify the movement of the resonance point with the sensation, and if the caller is associated with the vibration mode of the vibrator at the time of incoming call, it is not necessary to check the contents of the display screen. The caller can be identified.
