Description

The Utility model Integrated rewritable audio info module belongs to all commercial areas of the daily Use when accompanying audio information the product benefit increase or bring about new functionality of the product should. The field of application of the utility model is universal, but in particular z. As in toys, gifts, commodity price tags and photo or picture frames are used.

today According to the knowledge of the applicant, only audio modules are included Toys, merchandise and gift articles in a modified and only conditionally comparable form known.

In the case of today known utility models acoustic information in the case of "talking toy" is costly and reproduced with considerable technical effort

• - as part of an interactive toy connected to an external computer ( DE 29916785 U1 . DE 102004020669 A1 ) or
• As part of an interactive toy with speech recognition module ( DE 19617132 A1 ) or
• - used as a CD / MP3 player or iPod external to the toy ( US 2007/0042672 A1 ).

• – als Bestandteil einer kostspieligen TV Anlage, die sowohl visuelle als auch akustische Information dem Kunden unaufgefordert vermittelt, ohne dass der Letztere weder das Einsetzen oder Ausbleiben dieser Informationen noch die Signalstärke steuern kann.

The commodity information applications known today become audio information

• - as part of a costly TV installation that provides both visual and audible information to the client without the latter being able to control neither the onset or absence of this information nor the signal strength.

at used in today's gift items you can very simple sound-triggering mechanisms with very limited functionality and signal selection, neither rewritable still easy for the user to control.

Alles These applications only provide limited product specificity Possible applications and do not offer universal cost-effective and customer friendly, or simple in handling solution at.

The Utility model Integrated rewritable audio info module represents a universal technical platform based on a Loudspeakers / microphone sets with u. U. an amplifier, an electric battery unit, a microprocessor with a Communication interface (eg USB / Bluetooth and the like), a data memory, signal converter and external control buttons very reasonably priced and easy to handle for the user (the customer) as required acoustic signals (music, audio information) can send.

• 1. Ein- und Ausschalten
• 2. Lauter/Leiser

The customer operates the module by the function keys attached to the surface of the reference object (eg toys, gifts, nameplate or other everyday objects) as in claim 2:

• 1. Switch on and off
• 2. Louder / quieter

These Function keys can vary depending on the reference object Make the most comfortable for the customer are attached.

The Operational readiness of the module and the functional status will be like made in the protection claim 1 using a LED indicator light visible.

The Recording of the audio information takes place via a built-in Microphone or a linear interface as in the protection claim 3 instead of.

The Playback of the audio information takes place as in the protection claim 4 with the help of the built-in speaker.

The Download the audio information as well as manage and change the latter happens via a communication interface via an external computer as in protection claim 5.

Technical structure:

• • A DC source guaranteed Energy supply in the module;
• • Energy independent storage of acoustic data does not require power in the passive state;
• • USB interface or wireless interface is used the digital communication with the external computer;
• • Microphone converts sound vibrations into electrical Signal around
• • Sound source switch allows use of the Microphones or the linear interface as sound source;
• • A-D converter (microchip) converts analogue acoustic Signal to a digital signal;
• • Central / micro control unit, which after a certain Program controls the functions of the system parts of the module;
• • D-A converter (microchip) converts digital signal into an analogue acoustic signal;
• • Amplifier (microchip) amplifies the analogue acoustic signal for the speakers;
• • Linear interface - a standard connection to any source of analogue acoustic signal: stereo system, Radio, CD or MP3 player, etc .;
• • Control unit controls the operation mode of the entire Module: switching on and off, playback, recording, control of Volume;
• • Speaker (speaker set) converts analog electrical Signal into acoustic oscillations.

Steuerunsvorgänge:

• • The in energy independent Memory stored data will be in the after switching on Central unit then routed through the speakers to be audibly audible. Conversely, the recorded Data is passed from the central processing unit to the memory.
• • Via communication interface (eg USB), the data is transferred to the central unit.
• • Analogue acoustic signal comes from the microphone or from the linear interface;
• • Analogue acoustic signal reaches A-D converter (Microchip);
• • Digital acoustic data reaches the central unit;
• • Digital acoustic data reaches the D-A converter (Microchip);
• • Analogue acoustic signal reaches amplifier;
• • Control units send commands to the central unit;
• • Acoustic sounds from the speakers Signal;

Operating modes:

• • Connecting to computer and downloading the acoustic signal;
• • switching on and off the playing of the acoustic signal;
• • volume control;
• • Turning on and off the recording of the acoustic Data about the microphone;
