Abstract

The utility model discloses a concave-nest three-tone-way earphone with common sound source and an earphone structure; a front cover plate is in a concave-nest spherical reflex arc shape; the front cover plate is provided with a bass receiver, an alto receiver and a high-pitch receiver; the outside of the mid-voice receiver is covered by an alto isolation cover; the voice coil of the bass receiver, the alto receiver and the high-pitch receiver at the concave-nest spherical reflex arc commonly clings to vibrating diaphragm surface and is tangent to the concave-nest spherical reflex arc and has a common center of circle with the concave-nest spherical reflex arc; the front cover plate of the utility model adopts the bass receiver, the alto receiver and the high-pitch receiver, an alto receiver insulation cover is added to the back of the alto receiver to avoid the interference, the manufacture utilizes a reflection concave nest, the concave nest is the spherical reflex arc shape to be matched with the sound-reception of the ear pier, and the sound wave of the three receivers can reach the earhole at the same time, therefore, the utility model is easy to show good gathered sound.

Description

Recessed nest three sound roads are the source of sound earphone altogether

Technical field:

The utility model relates to Headphone structure.

Background technology:

Usually the auricular concha fore shell of earphone mostly adopts the single receiver of slab construction to make, and the reflection sound wave is at random, and sound effect is undesirable.

The utility model content:

The purpose of this utility model is to provide a kind of recessed nest three sound roads source of sound earphone altogether.

Front shroud is recessed nest spheric reflection arc; Front shroud is provided with bass receiver, middle pitch receiver and high pitch receiver.

Middle pitch receiver outside is covered with the middle pitch cage.

The recessed nest spheric reflection of front shroud arc baritone receiver, middle pitch receiver and the high pitch receiver voice coil loudspeaker voice coil vibrating diaphragm face of fitting jointly is with the tangent concyclic heart of recessed nest spheric reflection arc.

The utility model front shroud adopts bass, middle pitch, three receivers of high pitch, middle pitch receiver back adds the middle pitch cage and avoids interference, utilize the reflective concave nest to make, because of recessed nest is that a spheric reflection arc multiplies each other with ear Guo radio reception is auxilliary mutually, reaching three receiver sound waves can arrive earhole simultaneously, is easy to show good cohesion sound.

Description of drawings:

Accompanying drawing 1 is a three-dimensional installation diagram of the present utility model;

Accompanying drawing 2 is stereograms of the present utility model;

Accompanying drawing 3 is that the utility model is worn over the main pseudosection on people's ear.

Embodiment:

It comprises bonnet (2) and front shroud (7) and the earmuff (8) that support (1) connects. front shroud (7) is recessed nest spheric reflection arc; Front shroud (7) is provided with bass receiver (4), middle pitch receiver (5) and high pitch receiver (6).Middle pitch receiver (5) outside is covered with middle pitch cage (3).Wire rod (9) outreaches connecting line.Front shroud (7) recessed nest spheric reflection arc baritone receiver (4), middle pitch receiver (5) and high pitch receiver (6) the voice coil loudspeaker voice coil vibrating diaphragm face of fitting jointly is with the tangent concyclic heart of recessed nest spheric reflection arc.

During use, the utility model is leaned on in people's earhole (13).During playback, front shroud (7) is gone up the bass receiver (4), middle pitch receiver (5) and the high pitch receiver (6) that are provided with and is formed three-dimensional sound wave reflection cambered surface (10), sound wave secondary reflection cambered surface (11) and sound wave direct projection face (12) with people's earhole (13).
