Overview

The 3070 3W 8Ω rectangular speaker is a compact, high-efficiency unit designed for voice playback, sound output, and audio notification systems. It delivers clear sound across the 200Hz–20kHz range with a 3W maximum input power and a robust neodymium (Nd-Fe-B) magnet for high sensitivity. Ideal for voice recognition modules, embedded systems, DIY electronics, and multimedia devices.

Introduction

ลำโพงขนาดเล็ก 3070 Speaker 3W 8Ω ให้เสียงคมชัด เหมาะกับงาน Voice Playback, Sound Alert, โมดูลเสียง, หรือระบบแจ้งเตือนในงาน IoT และอุปกรณ์อิเล็กทรอนิกส์ทั่วไป ตัวลำโพงมีโครงสร้างแข็งแรง ใช้แม่เหล็ก Nd-Fe-B คุณภาพสูง และ Diaphragm แบบ PET ให้เสียงใสชัดทุกรายละเอียด รองรับการทำงานที่ 2W Rated / 3W Max ใช้กับบอร์ดขยายเสียง, โมดูลเสียงพูด, หรือระบบ Voice Recognition ได้เป็นอย่างดี

Exchange or return policy



Every item comes with a 30-day warranty. However, there are certain conditions that apply:

  1. The customer should not be responsible for any self-inflicted damage, such as incorrect power connections (for example, supplying 5V instead of the required 3.3V for a sensor).

  2. The product must be in perfect condition, without any breakage or damage caused by electricity (e.g., short circuits leading to electrical fires).

  3. The store does not accept product exchanges due to customer misunderstandings, such as purchasing the wrong size for their project or buying something without eventually using it. Customers can inquire about the product details and ensure compatibility before making a purchase by contacting us through our Line account @modulemore during business hours. Please note that there may be delays in response between 12:00 PM and 2:00 PM.

Return Policy: To initiate a product return, customers must provide the original receipt or a copy for quick verification. Returns can be sent to our store address by following these guidelines:

  1. Provide a detailed description of the damaged item(s).
  2. Mention any tests or experiments conducted by the customer.

Please note that the store reserves the right to make the final decision regarding product replacement or refund.
