Abstract

The utility model discloses an earphone, of which a sounding part comprises a moving coil module, the position corresponding to the moving coil module is mounted with a moving iron module, and a cavity is disposed between the moving coil module and the moving iron module. Using that the moving coil module can sound vigorous outstanding tone quality at low-frequency stage, combing with the moving iron earphone can sound pure and thorough sound at middle-frequency stage, and preserving the cavity between the moving coil module and the moving iron module, so the sound emitted from the moving coil module and the moving iron module can form better resonance in the cavity, therefore the earphone has better outstanding tone quality.

Description

A kind of earphone

Technical field

The utility model relates to a kind of earphone.

Background technology

Earphone of the prior art according to the type of its driver (transducer), can be divided into moving-coil earphone, electrostatic earphone, piezoelectric earphone, moving iron earphone, pneumatic earphone.

Wherein using maximum is moving-coil earphone, its theory structure such as Fig. 1, it and common sound equipment are similar, the coil 2 that is in the permanent magnetic field of magnetic patch 1 directly links to each other with vibrating diaphragm 3, coil drives the vibrating diaphragm sounding under signal code drives, signal process coil cutting magnetic line, thus drive vibrating diaphragm vibration sounding together.Advantage is to make relatively easily, and good linearity, distortion is little, frequency response is wide.It is deep at supper bass section sound, but not enough in alt section expressive force.

Another kind is the iron earphone, its theory structure such as Fig. 2, utilized electromagnet to produce alternating magnetic field, oscillating component is that an iron plate 4 is suspended in electromagnet 5 the place aheads, signal can make the electromagnet changes of magnetic field through electromagnet 5 time, iron plate is transmitted to the central point of a miniature vibrating diaphragm 7 by the pitman 6 of a precise structure, thereby produces vibration and sounding.Advantage be to use the life-span long, efficient is high.It is revealed the exact details in that the alt section is pure, but shows slightly inferior in low segment.

The utility model content

The purpose of this utility model is to provide a kind of earphone, makes its bass, alt that good tonequality can be provided.

The utility model discloses a kind of earphone, its pars stridulans comprises the moving-coil module, and moving swage piece is installed in the corresponding position of moving-coil module, leaves cavity in moving-coil module and moving swage interblock.

Earphone described in the utility model, the moving-coil module that the coil that is in the magnetic patch directly links to each other with vibrating diaphragm is housed in the earphone body, it is directly by coil vibration causing vibrating diaphragm sounding, better linear, can make sounding simple and honest in low-frequency range, at the opposite side relative with the moving-coil module, moving swage piece is installed, moving swage piece is sent to vibrating diaphragm by the vibration of iron plate through pitman, and its sounding is revealed the exact details in that the alt frequency range is pure.And in the middle of moving-coil module and moving swage piece, leaving cavity, its sound that swage piece and moving-coil module are sent forms better sympathetic response at this cavity, thereby makes the tonequality performance of earphone more outstanding.

Embodiment

Below in conjunction with accompanying drawing, the utility model is further described.

As shown in Figure 3 and Figure 4, the disclosed a kind of Headphone structure of the utility model, its pars stridulans comprises moving-coil module 8, it includes coil, vibrating diaphragm, magnet, coil directly with the vibrating diaphragm connection in magnet and magnetic field in.In the corresponding position of moving-coil module 8 moving swage piece 10 is installed, it comprises can vibrate iron plate, and iron plate is connected to vibrating diaphragm by pitman.Leave cavity 11 in moving-

coil module

8 and 10 of moving swage pieces, galenic 14 and back cover 15 before the outside of pars stridulans is with, earphone wire rod 16 is connected with pars stridulans through back cover.Adopt this structure, utilize the moving-coil module can make the simple and honest outstanding tonequality of sounding in low-frequency range, the sound that sends in the alt frequency range in conjunction with moving swage piece is pure thoroughly, and form sympathetic response through the cavity that its inside is left, make sound that entire headset sends compared with prior art, tonequality obtains very big breakthrough, makes tonequality show more perfectly.

For the tonequality that makes earphone sound more perfect, described earphone also comprises fixed support 9, and the middle part of fixed support 9 is provided with holddown groove, and moving swage piece is installed in the holddown groove, holddown groove links to each other with support bracket fastened barrel, is a plurality of areolas with the separated by spaces between holddown groove and barrel.By the fixing moving swage piece of fixed support, make the iron plate vibration sounding after, in a plurality of areolas, form sympathetic response with the sounding of moving-coil module, improve the sound acoustical quality.

For making this earphone performance more outstanding, at the head of earphone sound guide tube 12 is housed, link to each other with the earphone pars stridulans.Can make small and exquisite earphone head can put into darker duct part like this, thereby produce better audio visual effect.

For making earphone play good sound insulation and leakproof audio fruit, be connected with silica gel sheath 13 at the head of described earphone.Sound is imported in the ear, and Rou Ruan silica gel sheath also can play the protection ear in addition, and it is more comfortable to allow the consumer use.
