An auxiliary sound/light indicating device includes a housing, in which a control circuit composed of a microcontroller, an MP3 player, a light-emitting element, and a Bluetooth module is provided. The auxiliary sound/light indicating device is wirelessly connected to a mobile communication apparatus via Bluetooth connection. The microcontroller controls the emission of sound and light, enables ringing sound programming and caller ID display setting. Through the Bluetooth connection, the auxiliary sound/light indicating device can emit sound and/or light to inform a user of an incoming call on the mobile transmission apparatus and display the caller ID, allowing the user to decide whether to answer or reject the incoming call. And, when the mobile communication apparatus is out of an effective Bluetooth transmission range and the Bluetooth connection is interrupted, the auxiliary sound/light indicating device emits warning sound and/or light to remind the user of possible loss of the mobile communication apparatus. |
