Figure 10 representes the outside drawing of an earphone in other embodiments.This earphone especially is designed to PlayGear Stealth.This earphone has a lead 401 and an earphone outer covering 402.On earphone outer covering 402, be fixed with an ear hook 403 that when wearing earphone, can hang over the wearer's ear back.

Be provided with a slit in the earphone outer covering outside, can embed in the above and removable cover elements 404 of fastening.Through this cover elements 404 being fixed on the acoustic characteristic that can change earphone in the slit 405, so just can adopt various difform plug-in cover elements 404 on purpose to influence the acoustic characteristic of earphone.

So far the acoustic characteristic of an earphone its development stage just geometry through this earphone and size and employed material confirmed, can not be changed thereafter.For example reach the acoustics short circuit, need to use quieter material, such as similar materials such as silk, noise reduction paper, foamed materials in order to regulate.Can exert an influence to acoustic characteristic through material chosen.But also hope very much to let user oneself that the acoustic characteristic of earphone is implemented influence, enable oneself adjustment.

For example the adjustment for the acoustic characteristic of the earphone shown in Figure 10 can realize so that promptly, use different setting-in elements or cover cap 404, wherein, this setting-in element or cover cap 404 can change the acoustic characteristic of earphone.For example can produce or change spatial volume with acoustics effect through design to said setting-in element 404.For example can influence the spatial volume at the converter system rear portion in the earphone 400, the acoustic characteristic of earphone is changed through this setting-in element.In the execution mode that Figure 10 representes, removable acoustic element is designed to setting-in element 404, and therefore can see from the outside.

In addition, also can removable acoustic element be designed to concealedly, can not see from the outside.This acoustic element for example can be configured to promptly can be screwed into the silencer element of the ammunition cartridge type (Kartuschenartige) that also can be screwed.These silencer elements or acoustic element for example can have sponge or can change or comprise the definite volumetric spaces that influence acoustic characteristic.

Therefore can adopt the various acoustic characteristic of earphone that can make to be adapted to acoustic element or the silencer element that the user personal like needs.In addition, said acoustic element or silencer element can be coordinated with different musical genre mutually, so just can earphone be adjusted to a definite musical genre through changing said acoustic element or silencer element.This for example reaches through designing an electronic compensator in tone playing equipment up to now always, therefore can directly be configured on the earphone.

Therefore adopt some removable silencer elements that have acoustic function equally.This type silencer element both can be used for headphone, also can be applied in the earphone, so that influence the acoustic characteristic of earphone.Said removable silencer element or acoustic element preferable configuration become, and the terminal use can oneself change.Therefore but preferably but said silencer element is configured to insertable plug-in or screwing type.

For example in the shell of an earphone, can be provided with groove, can the silencer element or the acoustic element of an ammunition cartridge type be inserted or be screwed in the groove, can change the acoustic characteristic of earphone simultaneously thus.

For example can influence frequency characteristic, bass playback, high pitch playback and middle pitch playback through removable silencer element.

When silencer element or acoustic element are designed to the cover cap of an earphone, then, therefore changed the tone characteristic of earphone through changing cover cap can for example become earphone an opening from the formal transformation of a sealing form.For example the earphone of a sealing is transformed into the earphone of an opening, has following advantage, that is, can experience environment better through changing removable silencer element.When this advantage is embodied in by bike especially.But less when experiencing ambient noise when more hoping, just can be through changing the earphone that silencer element be transformed into the earphone of an opening sealing.

When said silencer element was designed to the cover cap of an earphone, cover cap that then can be through adopting the different designs structure exerted an influence to the volume of ventilating opening back, had therefore changed the acoustic characteristic of earphone based on the variation of ventilation hole volume.For example, adopt different volumes in the above between the cover cap that can describe and the earphone in order to handle the playback effect of earphone.As substituting or arbitrary way, a hole or opening also can be set on cover cap, this equally also can cause the change of headphone acoustic characteristic.Although in Fig. 4, only show a kind of earphone with hook, removable acoustic element equally also can be migrated on earphone, for example headphone, PlayGear Stealth or the in-ear phone of other type.
