collinsemasi

@copilot I’m designing a custom voice-controlled speaker and I initially want it to have buttons, Bluetooth, Wi-Fi, and rechargeable battery. Help me brainstorm and develop a comprehensive product requirements document. Ask me one question at a time, waiting for my response before moving to the next question.

copilot

Great, let's get started! To create a comprehensive product requirements document, my first question is:

1. What specific functions or features do you want the buttons to perform on your custom speaker?

For example, would you like them to control volume, play/pause, skip tracks, etc.?

collinsemasi

they can add a manual off/on functionality, manual voice assistant activation, volume control, play/pause, and maybe Bluetooth control

copilot

Perfect, that's a good set of functionalities for the buttons. Here's a quick summary for the button controls:

Power On/Off
Manual Voice Assistant Activation
Volume Control
Play/Pause
Bluetooth Control

Next question:

2. What kind of voice assistant integration do you plan to use?

Do you have a specific voice assistant service in mind, like Google Assistant, Amazon Alexa, or something custom?

collinsemasi

I plan to integrate Amazon Alexa as the primary voice assistant. I’m also considering the possibility of allowing flexibility for future integration with other services, like Google Assistant, depending on user preferences or updates in technology.

copilot

Integrating Amazon Alexa is a solid choice, and keeping the design open for potential integration with other services is a smart approach for future-proofing. Here’s the updated requirement:

Primary voice assistant: Amazon Alexa
Design flexibility to allow future integration with other services like Google Assistant

Next question:

3. What is your target battery life for the speaker when it's in active use and in standby mode?

This will help us determine the battery capacity and power management requirements.

collinsemasi

For active use, I’m targeting a battery life of 10-12 hours. In standby mode, I’d like the battery to last for at least 48-72 hours

copilot

Got it! Here are the updated battery requirements:

Battery Life in Active Use: 10-12 hours
Battery Life in Standby Mode: 48-72 hours

Next question:

4. What audio quality or output specifications are you aiming for?

This includes speaker wattage, number of drivers, frequency response range, etc.

collinsemasi

I’m aiming for high-quality audio with the following specifications:

Speaker Wattage: 20-30 watts per channel for powerful, clear sound.
Number of Drivers: At least 2 mid-range drivers and 1 tweeter for balanced audio output. Considering adding a subwoofer for enhanced bass.
Frequency Response Range: 20Hz to 20kHz to cover the full spectrum of human hearing.
Total Harmonic Distortion (THD): Less than 1% to ensure minimal distortion at higher volumes.
Signal-to-Noise Ratio (SNR): At least 85dB for clear sound without background noise.

copilot

Great specifications for achieving high-quality audio output! Here are the audio quality requirements summarized:

Speaker Wattage: 20-30 watts per channel
Number of Drivers: At least 2 mid-range drivers, 1 tweeter, and possibly a subwoofer
Frequency Response Range: 20Hz to 20kHz
Total Harmonic Distortion (THD): Less than 1%
Signal-to-Noise Ratio (SNR): At least 85dB

Next question:

5. What kind of Bluetooth and Wi-Fi capabilities or standards do you plan to include?

Consider the range, version, and any additional features like multi-device connectivity or high-speed data transfer.

collinsemasi

I'm comfortable with whatever you'll pick here

copilot

Got it, I'll suggest some standard Bluetooth and Wi-Fi capabilities for robust performance:

Bluetooth Version: 5.0 or newer, for improved range, speed, and multi-device connectivity
Wi-Fi Standard: Dual-band Wi-Fi supporting 802.11 a/b/g/n/ac for compatibility and strong performance
Additional Features: Support for high-quality Bluetooth audio codecs like aptX or AAC for better audio transmission

These specifications should ensure reliable connectivity and high-quality audio streaming.

Next question:

6. What kind of connectivity ports would you like to include?

Consider options like USB-C for charging, auxiliary input for wired connections, or any other interfaces you think are necessary.

collinsemasi

I'm thinking of a single USB-C port for charging.

copilot

A single USB-C port is a modern choice that supports fast charging and offers a reversible connector, which is user-friendly. Here's the updated requirement:

Connectivity Port: USB-C for charging

Next question:

7. Are there any specific design or aesthetic considerations for the speaker's enclosure?

This might include materials, color options, size, or shape that align with your vision for the product.

collinsemasi

Not really. I haven't thought about those I want to focus on the circuit part first

copilot

Understood, focusing on the circuit design first makes sense, especially for functionality. We can always address design and aesthetics later when the core functionality is established.

Next question:

8. Are there any environmental or durability considerations, such as waterproofing or rugged design features, that you'd like to include?

This might influence the component selection and overall design approach.

collinsemasi

Yes, I’d like to incorporate the following environmental and durability features into the speaker design:

Waterproofing: Achieve at least an IPX5 rating to protect against water splashes, making the speaker suitable for outdoor use or placement in humid environments like bathrooms.
Dust Resistance: An IP5X rating for dust protection, ensuring longevity even in dusty conditions.
Rugged Design: Reinforced corners and a durable, shock-absorbent material around the base to protect against drops or impacts.
Temperature Resistance: Ensure the speaker can operate effectively in a wide range of temperatures, from -10°C to 45°C, for use in various climates.
Battery Protection: Overcharge and over-discharge protection to extend battery life and prevent damage under extreme conditions.

copilot

These environmental and durability features are important for making the speaker versatile and resilient. Here’s the summary:

Waterproofing: At least IPX5 rating
Dust Resistance: IP5X rating
Rugged Design: Reinforced corners and shock-absorbent material
Temperature Resistance: Operational range of -10°C to 45°C
Battery Protection: Overcharge and over-discharge protection

Next question:

9. Do you have any specific dimensions or weight considerations for the speaker?

This helps in ensuring portability while managing space for components.

collinsemasi

Not really, but as small as possible. Also ask the last 2 questions make sure to prioritize what's important

copilot

Great, I'll note that compactness is a priority:

Size Consideration: As small as possible, balancing component space and portability

For the remaining two important questions:

10. Are there any user interface elements, like LED indicators or an LCD screen, you'd like to incorporate for feedback or control?

11. Do you have a target price range or cost constraints for the device, which might influence component choices and design decisions?

collinsemasi

I’d like to include the following user interface elements:

LED Indicators: A multi-color LED ring around the top edge to provide visual feedback for various functions, such as power status, Bluetooth pairing, voice assistant activation, battery level, and notifications.

I’m aiming for a target price range of $150 to $200.

copilot

Here's the added information for user interface and budget constraints:

User Interface Elements:
- LED Indicators: Multi-color LED ring for visual feedback (power status, Bluetooth pairing, voice assistant activation, battery level, and notifications)
Target Price Range: $150 to $200

This gives us a comprehensive overview of your custom voice-controlled speaker requirements. With all these details, you can now start the schematic and component selection in Flux. If you'd like help with specific circuit designs or component selection, feel free to ask!
