Adphox Co., Ltd.

We manufacture and sell corona discharge testing machines, binaural microphones, and so on.

We research and develop, manufacture, and sell corona discharge testing machines (partial discharge test machines), sound collectors (hearing aids), and binaural microphones. Corona discharge becomes a problem when controlling voltages of 300 V or above using an inverter, because it may cause a discharge that results in an insulation breakdown. Our corona discharge testing machine can electrically detect this discharge phenomenon by making use of a high-efficiency power supply and detector we have originally developed. Our binaural microphone can record sound exactly as we hear it. It has smooth characteristics from the lower frequency range to wide-spectrum sound, so it is utilized by professionals because of its excellent sound quality.

Inquiry

Sales Pitch

Our company has a lineup of characteristic products such as corona discharge testers, sound collectors (hearing aids), and binaural microphones.

1. Corona discharge tester
This device electrically tests inverter-derived corona discharge at a high frequency.
We independently developed a power supply for a detector so that we can detect corona discharge signals.
We also provide rental and consignment test services.
Feel free to contact us first if you have any issues about corona discharge.

2. Sound collector
You can hear sounds clearly with no high-pitched noise. You can use the device at once because it is adjusted automatically.
A hearing aid generally requires adjustment according to the user. However, our products do not require adjustment by the dealer. This is because the voice clarification circuit (already patented) automatically adjusts the amplification characteristics to make sounds clear.

3. Binaural microphone
You can record good sounds by binaural recording suitable for video shooting.
The frequency response is flat from low to high sounds and the sensitivity is high. A real head is used for recording and not a dummy head.
This product is popular among professionals in the music industry and for research.

Other presentation

[Company strength]
Corona discharge is a partial discharge phenomenon that occurs under high-frequency and high-voltage conditions. Corona discharge has been becoming a problem in recent years when using an inverter to control voltages of 300 V or above. This is because corona discharge can cause a discharge that results in insulation breakdown. Our corona discharge testing machine can detect this discharge phenomenon electrically by using an efficient power supply and a detector that we have developed independently. Our sound collector has countermeasure functions against noise, unlike ordinary hearing aids. The amplification characteristics are automatically adjusted by a voice articulation circuit, so voices become clear without being metallic-sounding. It is very simple to use. Our binaural microphone has smooth characteristics from the lower frequency range to wide-spectrum sound, and it is utilized by professionals because of its excellent sound quality.

[Business description]
We research and develop, manufacture, and sell corona discharge testing machines (partial discharge test machines), sound collectors (hearing aids), and binaural microphones. We also accept OEM contracts.

[Industry]
Electronic equipment R&D, manufacturing, and sales

[Representative's message]
We have been continuously working on manufacturing user-friendly, worthwhile products in the fields of testing machines and sound collectors. We want to maintain this policy and do our best to make a broad range of contributions to society.

[Company structure for market development/overseas expansion]
We receive orders for testing machine leasing and consignment testing as well as sales. Female users account for about half the users of competing sound collector products, but our products have not yet become popular among women, and this has been a struggle for us. We want to advance our development with awareness of female users. We hope to widely expand sales of our binaural microphones from Japan to foreign countries.
