## Production Notes
### Before Recording
1. **Prepare 8 slides in Canva** (16:9) — see `[SHOW:]` cues below
2. **Each slide = one segment** — don't put multiple scenes on one slide
3. **Background:** Dark (#0A0A0A) or clean white — match Yukun brand
4. **Font:** Inter Bold for titles, JetBrains Mono for specs
5. **Product photos:** Use actual teardown screenshots or stock photos of a handheld fan
### AI Voice Settings
| Setting | Value |
|:---|:---|
| Speed | 0.95× (slightly slower than default for technical clarity) |
| Pitch | Default (no adjustment) |
| Pauses | `...` = 0.5s, `[pause 1s]` = 1s, `[pause 2s]` = 2s |
| Emphasis | `**word**` = slightly louder + slower |
| Tone tags | `[casual]` `[surprised]` `[serious]` `[excited]` |

## OPTIMIZED SCRIPT

### SEGMENT 1 — INTRO (0:00-0:25)
**Slide 1:** Hero shot of a handheld fan on white background. Yukun logo top-right. Title: "What's Inside a $9 Fan?"
```
[casual]
Two hundred million handheld fans are sold every year.
[pause 1s]
And almost every single one of them... uses the exact same motor.
[pause 1s]
Today, we're taking one apart.
[SHOW: Slide 1 — fan hero shot]
We'll see what's inside. What **fails**. And how to make it **better**.
[pause 2s]
I'm from Yukun. Let's open it up.
```
---
### SEGMENT 2 — TEARDOWN (0:25-1:00)
**Slide 2:** 4-step teardown sequence — 4 photos arranged horizontally:
1. Removing screws | 2. Prying snap tabs | 3. Separating halves | 4. Exposed internals with labels
```
[enthusiastic]
Four screws on the bottom. [pause 0.5s] Gone.
[SHOW: Slide 2, step 1 highlighted]
Snap tabs along the seam. [pause 0.5s] A spudger pops them open.
[SHOW: Slide 2, step 2 highlighted]
Separate the two halves...
[SHOW: Slide 2, step 3 highlighted]
And **there it is**.
[pause 2s]
[SHOW: Slide 2, step 4 — all components labeled]
One motor. One switch. One battery. One boost board. One plastic fan blade.
[serious]
Five components. That's the entire product.
```
---
### SEGMENT 3 — THE MOTOR (1:00-1:45)
**Slide 3:** Close-up of N20 motor with callouts:
- "12mm diameter"
- "Metal spur gears"
- "50:1 reduction ratio"
- "6,500 RPM → 130 RPM at blade"
```
[technical]
This... is an N20 brushed DC gear motor.
[pause 1s]
[SHOW: Slide 3 — motor close-up with callouts]
Twelve millimeters in diameter. [pause 0.5s] Metal spur gears inside.
Six thousand five hundred RPM at the motor shaft... [pause 0.5s]
reduced to about one hundred thirty RPM at the blade.
[pause 1s]
That's a fifty-to-one reduction. [pause 0.5s] In a package the size of your thumbnail.
[casual]
These motors cost about a dollar. In volume.
That's why they're everywhere. [pause 0.5s]
Fans. Toys. Smart locks. Robot grippers. [pause 0.5s] Same motor.
```
---
### SEGMENT 4 — WHAT FAILS (1:45-2:15)
**Slide 4:** Split screen — left side "What Fails", right side "The Fix"
Left column:
- "Brush wear → 5,000 hrs"
- "Gear noise → 58 dB"
- "Switch oxidation → dead in 6 months"
```
[serious]
But here's the problem.
[pause 1s]
After about five thousand hours... the brushes wear out.
[pause 0.5s]
The gears get loud. [pause 0.5s] Fifty-eight decibels loud.
[pause 0.5s]
And the little tactile switch? [pause 0.5s] Unsealed contacts.
[pause 1s]
Six months in a humid bathroom... [pause 0.5s] and your customer presses the button.
Nothing happens. [pause 1s] One-star review.
```
---
### SEGMENT 5 — THE UPGRADES (2:15-2:50)
**Slide 5:** Side-by-side comparison table:
| | Stock | Upgrade | Delta |
|:---|:---|:---|:---|
| Motor | N20 Spur | N20 Planetary | -8 dB, +3× life |
| Switch | Tactile, IP00 | Tactile, IP67 | No oxidation |
| Cost | — | +$1.15/unit | — |
```
[enthusiastic]
The good news? [pause 0.5s] All of this is fixable.
[pause 1s]
[SHOW: Slide 5 — comparison table, highlight row 1]
Swap the spur gear for a planetary gearbox.
[pause 0.5s]
Same twelve-millimeter mounting. [pause 0.5s] Six to eight decibels quieter.
Three times the service life. [pause 0.5s] Cost difference?
[pause 1s]
About one dollar per unit.
[pause 1s]
[SHOW: Slide 5 — highlight row 2]
A fifteen-cent IP67 sealed switch... [pause 0.5s] with gold-plated contacts...
[pause 1s]
Saves a nine-dollar product from a one-star review.
```
---
### SEGMENT 6 — NOISE DEEP DIVE (2:50-3:15)
**Slide 6:** Noise source breakdown — stacked bar chart or pie chart:
- Gear mesh: 42 dB
- Blade turbulence: 38 dB
- Motor bearing: 32 dB
- Housing resonance: 28 dB
- Total: 58 dB
```
[technical]
Let me break down that fifty-eight decibels. [pause 0.5s] Where is it coming from?
[pause 1s]
[SHOW: Slide 6 — noise breakdown]
Forty-two decibels... from the gear teeth meshing. [pause 0.5s]
Thirty-eight... from blade turbulence.
Thirty-two... from the motor bearing.
Twenty-eight... from the plastic housing vibrating.
[pause 1s]
Add a rubber grommet between the motor and housing... [pause 0.5s]
and you drop five to seven decibels. [pause 0.5s] For fifteen cents.
[pause 1s]
Switch to planetary gears... and you kill another six to eight.
[casual]
That's fifty-eight down to forty-five. [pause 0.5s] Perceptually? Half as loud.
```

### SEGMENT 7 — FROM TEARDOWN TO YOUR PRODUCT (3:15-3:45)
**Slide 7:** BOM table simplified for video — 3 columns: "Part | Stock | Yukun Replacement"
With QR code or URL at bottom: yukun-drive.com
```
[excited]
So you've seen the teardown. [pause 0.5s] You've seen the failures.
You've seen the fixes.
[pause 1s]
[SHOW: Slide 7 — simplified BOM table]
Now... if you're building a fan. Or fixing a bad batch.
[pause 0.5s]
Everything on this table... is available from us.
[pause 1s]
The motor. The switch. Custom gear ratios.
Even injection molding for your housing.
[pause 1s]
Samples ship in one week. [pause 0.5s] From Shenzhen. Worldwide.
```
