Description

  The present invention relates to a headset device that is wirelessly connected to an external device such as a mobile phone and exchanges signals, and that allows a user to make a hands-free call by using the device while wearing the ear shell, for example.

  The mobile phone has a wireless transceiver, speaker, and microphone, and can be connected to the phone body using a short-range wireless system with a headset device attached to the user's head, etc. Those having specifications are provided. By using such a headset device, the cellular phone is provided with a so-called hands-free function that enables a call without gripping the phone body, thereby improving usability.

  The mobile phone wirelessly connects the headset device with a Bluetooth wireless system. The Bluetooth wireless system can transmit and receive signals based on mutual recognition between mobile phones, personal computers, and digital devices installed in a short distance of about 10M using a carrier wave in the 2.4 GHz frequency band. This is a short-range wireless system. In the Bluetooth wireless system, the Bluetooth module is relatively inexpensive and highly versatile, and is compact and lightweight, and has low power consumption. Therefore, the Bluetooth module is mounted on various mobile devices. As a headset device provided with a Bluetooth module, for example, Patent Literature 1 has proposed.

On the other hand, in a personal computer system or the like, a USB connection is made between components having a USB function including an interface and a hub standardized by the Universal Serial Bus (hereinafter referred to as USB) standard. Mutual exchange of information and the like is performed (see, for example, Patent Document 2). Also in a mobile phone, by mounting such a USB function, a peripheral device of a personal computer system is configured to exchange information and the like.

  By the way, in the mobile phone, further multi-functionalization and multi-functionalization are achieved, and it is not only positioned as a mere calling means by providing a large liquid crystal screen, a large capacity memory or an information connector, but also so-called information. The specific gravity as a terminal device is also increasing. In a mobile phone, for example, various information and contents are obtained by connecting to an Internet network or a music distribution service network, and the information is output from a speaker or a liquid crystal screen and transferred to a personal computer or an appropriate recording medium for recording. It also comes with a function to do.

  The mobile phone is also provided with a so-called memo recording function for recording contents in the built-in memory in the middle of a call, and can be played back and confirmed after the call. Further, the mobile phone has a function of transferring the recorded content to, for example, a personal computer connected via USB. However, in a mobile phone, there is a problem that when a hands-free call is performed using a headset device, even if a memo is required, it is not possible to cope with a habit.

  Since the headset device is required to make a hands-free call when the above-described new function is installed in the mobile phone, the demand for the corresponding function as an additional device is extremely large. However, in the headset device, a small, lightweight and low power consumption specification is indispensable for its function. Therefore, the headset device is conventionally positioned exclusively as a single-function accessory device for performing a hands-free call. Only a Bluetooth function and a speaker and a microphone as an input / output means are mounted.

  By the way, in various electronic technologies, due to remarkable progress in high integration technology, fine wiring technology, and mounting technology, the Bluetooth module is miniaturized, and the speaker and microphone are also miniaturized while maintaining high performance specifications. It is illustrated. Headset devices are also becoming smaller and lighter by adopting such electronic technology, but with the increased functionality of mobile phones, which are the main devices, multifunctional functions that can be used for various purposes Is required.

  Therefore, the present invention provides a so-called voice recorder function or personal computer system using a built-in speaker and microphone from a single-function specification that has been used only for hands-free calls even when wirelessly connected to a mobile phone.
