Description

The Cooper-Rand Tone Generator is an innovative intra-oral artificial larynx system designed to restore speech capabilities for individuals who have lost their natural voice, such as laryngectomy patients. This sophisticated device offers a natural-sounding voice through its unique two-piece design, comprising a hand-held control unit and an oral unit integrated into a dental prosthesis.

Design and Functionality

• Two-Piece System: The hand-held control unit and the oral unit work seamlessly together, with the latter mounted in the mouth using a dental prosthesis like a full upper denture or retainer.
• Sound Modulation: The device generates voice tones within the oral cavity, allowing users to modulate speech elements such as pitch, loudness, and tonal quality. This enables the simulation of natural speech characteristics, including fricative and aspiration sounds.

User Controls

• Ergonomic Operation: The hand-held unit features a small keyboard or dial controls for easy adjustment of pitch and volume, offering up to 32 combinations of frequency and loudness.
• Wireless Communication: Control signals are transmitted wirelessly to the oral unit, enhancing convenience and ease of use.

Oral Unit Specifications

• Components: The oral unit includes a loudspeaker, power amplifier, battery, and receiver, all encapsulated within the dental prosthesis made from conventional dental acrylic.
• Protection Features: A diaphragm or membrane protects the speaker from moisture and bacteria, while a venting system prevents contaminants.

Power and Maintenance

• Battery Options: Operates on standard 9V alkaline or rechargeable batteries, with power-saving circuits to optimize usage.
• Durability: Known for its durable design, with many units in service for over 20 years. Maintenance involves regular washing or replacement of tubes and connecting cords.

Customization and Programmability

• Microprocessor-Based System: Allows for programmable digital controls and waveform storage, enabling customization of voice tones.
• Material Construction: The Tone Generator features gold anodized aluminum covers on a high-impact plastic frame.

Dimensions

• Pulse Generator: Measures 2.6" x 4.2" x 1" and weighs 7.75 oz with battery.
• Tone Generator: Measures 1" x 1" and weighs 1 oz.
