Doppler effect museum exhibit

A Doppler effect museum exhibit combines a covered linear apparatus with a wall-mounted screen and visitor controls. The format invites observation of relative motion and its accompanying explanation, helping visitors connect a familiar change in perceived sound with the scientific language of frequency.

THE ACTIVITY & MECHANISM

Connect motion with changing sound frequency

A travelling assembly inside a long covered display provides a visible example of relative motion beside explanatory media. The Doppler effect concerns a change in observed frequency as a sound source and listener approach or separate. Before interpreting a heard change, confirm which part moves and where the sound source and listener are located.

REFERENCE & PROJECT SCOPE

Reference specifications.

Use the reference dimensions and operating information to plan the exhibit. The agreed project drawings define the supplied configuration, installation interfaces and service access.

Approx. L × W × H: 1,800 × 1,100 × 2,200 mm
Exhibit theme: Fundamental Science
Visitor activity: Explore · Observe · Discuss
Reference operation: Watch the moving assembly beneath the covered linear tabletop. The source supports a physical demonstration but does not establish the audible pitch sequence.
Power & supply: Powered versions can be configured for 110/220 V AC, 50/60 Hz. The table drawing includes an internal acrylic tank. Confirm filling, draining, electrical supply, and final mounting requirements for the supplied version.
Reference construction: The matching table drawing lists a Q235 frame, artificial-stone top, ultra-clear tempered-glass cover, and acrylic tank.
Configuration options: Appearance, interpretation language, controls and installation arrangement by project agreement
Daily operating schedule: 8 hours per day
Scheduled maintenance: Every 30 days
Factory dispatch lead time: 30–120 calendar days after design approval and receipt of the deposit. Transit time is additional.
Minimum custom order: One exhibit

Approximate planning estimate: 1800 × 1100 × 2200 mm (L × W × H). Freestanding linear demonstration table and its associated rear display/supports; excludes the full gallery wall.

Reference configuration notes

Covered linear apparatus: A transparent cover encloses the long demonstration area.
Wall screen: A large screen provides interpretation above the table.
Control edge: Visitor controls are arranged at the front edge of the workstation.

Customisation, installation & support

01Reference envelope: Approximate planning estimate: 1800 × 1100 × 2200 mm (L × W × H). Freestanding linear demonstration table and its associated rear display/supports; excludes the full gallery wall.
02Configuration: Coordinate audio level, source motion, visitor comparison positions and access to the covered track.
03Visitor experience: Confirm the intended audience, accessible viewing and interaction positions, final instruction languages and supervised operation where needed.
04Service and handover: Agree access routes, replaceable components, operating checks and the handover documentation for the final configuration.

Delivery, installation & after-sales terms

Payment: A 50% deposit is payable after the contract is signed. The remaining balance is paid after acceptance and before dispatch, so full payment is received before dispatch. Payment methods are agreed in the contract.
Packaging & transport: Metal shipping cases or multilayer wood-panel shipping cases. Transport arrangements and costs are agreed to suit the project.
Materials & painted finish: Common material options include Q235 steel, stainless steel, aluminium alloy, PVC, acrylic, engineering plastics. The combination is selected for each configuration. Marine anti-corrosion paint with a piano-gloss automotive paint finish. Applied to painted parts.
Typical power · powered versions: Standard products: 100–500 W; oversized installations: 1,000–5,000 W. Typical ranges for powered versions. Confirm the selected model and final connected load.
Product maintenance: Suggested inspection points: linear carriage and travel path, cover retention and cleanliness, tank/window condition and electronics separation. Confirm the service procedure at handover.
Installation & training: Complimentary training is available on site or remotely, according to project needs. If installation or on-site after-sales service is not included in the product price, the customer pays the actual travel expenses incurred, unless the contract provides otherwise.
Factory acceptance & handover: Mid-production and pre-dispatch checks are provided. Factory acceptance can take place in person at the factory or through acceptance videos. Installation and operating videos, written installation and operating instructions, drawings and a spare-parts list are provided.
Complimentary parts: 24 months of complimentary spare-parts support, starting when the exhibit is handed over for use. Covers faults not caused by the user. User-caused or deliberate damage is excluded. Exhibit Engineers pays the shipping cost of complimentary spare parts during the 24-month support period.
Warranty & repair labour: The whole-exhibit warranty period and repair labour scope and charges are agreed in the contract.

Can we discuss a prototype or sample for a custom version?

Yes. Prototype testing and sample fabrication are available for custom projects. Discuss which functions or features you need to review for your version. The scope, cost and schedule are agreed for the project.

How prototype testing & samples work

What changes in the Doppler effect?

Relative motion along the source-observer direction changes the observed wave frequency. Sound provides a familiar example of this relationship.

What should we confirm before ordering?

The website video is silent, so it cannot verify pitch or sound quality. The original sound sequence, measured outputs and operating speed remain to be confirmed separately.

What do the images and videos show?

The gallery labels photographs, video frames, renderings and the dimension drawing. Physical footage is identified separately.
