- the user slides the slider 36 in the direction opposite to the storage space, and removes the speaker section 2a from the storage section 104.
- the speaker portions 2a and 2b can be removed from the main body 101 of the note type PC1. For this reason, the user can arrange the speaker units 2a and 2b at arbitrary positions, select a sound direction according to his / her preference, and obtain a good sound effect. The user can obtain a good acoustic effect even if the note type PC 1 is reduced in size or thickness.
- the speaker unit 2a when the speaker units 2a and 2b are stored in the storage unit 104, the speaker unit 2a is fixed. Therefore, it is not difficult to carry the notebook PC 1.
- the state of the power supply of the speaker units 2a and 2b and the state of communication between the main unit 101 and the speaker units 2a and 2b are detected and notified to the user. Therefore, the user can easily grasp the states of the speed force portions 2a and 2b.
- the audio signal is transmitted from the main unit 101 to the speaker unit 2a by digital communication. , 2b.
- audio signals can be transmitted and received well.
- the attachment detection unit 2 3, 2 8, speaker unit 2 a: 2 b is between speaker unit 2 a, 2 b and the main body 1 0 1 if installed in the main body 1 0 1 Are physically connected, and the main unit 101 and the speaker units 2a, 2a, 2b are connected via a line that is disconnected when the speaker units 2a, 2b are removed from the main unit 101.
- 2 Sends and receives call signals and answer signals between and.
- the attachment detectors 23 and 28 cannot transmit / receive the calling signal and the answering signal, it determines that the speaker units 2a and 2b have been removed from the main unit 101. I do.
- the attachment detection section 23 and the power supply control section 25 of the main body 101 may be realized by operations of, for example, the CPU 4 and the south bridge 7 instead of the built-in controller 12.
- the memory 5 and the hard disk 8 may be used instead of the memory 24.
- the communication control section 27 of the main body 101 may be realized not by the south bridge 7 but by operations such as the embedded controller 12 and the CPU 4.
- the operations of the attachment detection unit 23, the power control unit 25, and the communication control unit 27 of the main body 101 are managed by a utility program executed by the CPU. Good. Utility
- the main unit 101 includes the state of remaining power of the speaker battery 18 and the state of wireless communication between the main unit 101 and the speaker units 2a and 2b. It may be displayed by the display device 103.
- the main unit 101 holds the speaker units 2a and 2b when the speaker units 2a and 2b are pushed into the storage unit 104, and holds the held speaker units 2a and 2b.
- a structure in which the speed force portions 2a and 2b are released when 2b is further pushed in may be applied.
- the distance between the main unit 101 and the speaker units 2a and 2b is detected by various methods such as wireless communication availability, and when it is determined that the distance exceeds a predetermined range, the speaker unit 2a is detected. , 2b may output a warning sound, whereby loss of the speakers 2a, 2 can be prevented.
