Headphone Speaker Diaphragm Orientation for Sound Quality
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional headphones face challenges in producing high-quality sound due to the fixed positions of speaker casings relative to the user's ears, which limits the adjustment of speaker angles to improve sound quality.
Innovation Solution
The headphone design adjusts the angle of the diaphragms within the speaker casings based on experimental findings to simulate the effect of changing speaker locations, allowing for improved sound quality without physically moving the speaker casings.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Manufacturing precision
If the speaker casings are fixed relative to the user's ears, then the headphone structure is simple and easy to manufacture, but the sound quality cannot be optimized through angle adjustment
Solution Approach 1:
The speaker system is divided into independent speaker units, each with adjustable orientation. The diaphragms are positioned at different angles (60-80 degrees from the horizontal plane) to create distinct sound sources, allowing independent optimization of each speaker's acoustic contribution while maintaining overall structural simplicity
Solution Approach 2:
The invention introduces vertical dimension to speaker placement by positioning diaphragms at different angles relative to the horizontal plane. This three-dimensional arrangement of sound sources (different heights and angles) creates a more realistic sound field without complicating the basic headphone structure
2Measurement precision
If the speaker angles are adjusted to reduce location errors, then the sound clarity and presence improve, but the headphone structure becomes more complex
Solution Approach 1:
The invention optimizes specific geometric parameters - positioning diaphragms at angles of 60-80 degrees from the horizontal plane and spacing them 10-30mm apart vertically. These parameter optimizations reduce average location errors and improve sound clarity while maintaining a relatively simple overall structure that doesn't require complex adjustment mechanisms

AI summary
The present disclosure provides a headphone that enables a user to hear high-quality sound. A headphone includes a speaker casing and a headband. The speaker casing has a main speaker unit and a support member that supports the main speaker unit. The headband is connected to the speaker casing and is to be placed on a head of a user. The support member supports the main speaker unit with a main plane of the main speaker unit being positioned at an angle ranging from 10° to 30° inclusive with respect to a main plane of the support member, so that the main plane of the main speaker unit faces an ear lobe of the user.
