Abstract

The utility model discloses an inner ear type earphone, which comprises an outer casing, an earphone silicon rubber sleeve, a resonance cavity and an ear handle, wherein the outer casing includes a seat and an upper cover, the earphone silicon rubber sleeve placed at the front end of the outer casing is capable of being stuffed into an ear canal, the resonance cavity is formed by the seat and the upper cover in a sealed way, and the ear handle is connected with one side of the upper cover. Additionally, the resonance cavity is provided with an acoustic component which transforms electric signals to acoustic wave signals, signal transmission lines extending from one end of the ear handle is connected with the acoustic component, and the resonance cavity is a round barrel shaped wooden resonance cavity. The inner ear type earphone aims to overcome the shortcomings that the resonance cavities of earphones of the prior art cause chaos on phase positions of acoustic wave superposition generating portions after reflecting acoustic waves, thereby providing an inner ear type earphone with good effects of high, middle and low pitches, clearly distinguished timbre levels of various frequencies and good acoustic quality.

Description

Inner ear formula PlayGear Stealth

Technical field

The utility model relates to a kind of earphone, relates in particular to a kind of inner ear formula PlayGear Stealth.

Background technology

Conventional earphone is by loudspeaker the signal of telecommunication to be changed into sound wave, and prevents that by resonator radiation sound wave sound wave from dispersing, thereby sound wave is sent to ear by a direction as far as possible.But because traditional PlayGear Stealth generally adopts injection molding of plastics, volume is little, and the echo space is restricted, middle bass sound radiation and make both poor sound quality.

And the sound wave stack can cause band segment to strengthen behind the resonator reflective sound wave of traditional earplug earphone, but stack also can cause sound wave band segment phase place confusion simultaneously, particularly in low tonequality muddiness, lack stereovision.

The utility model content

The resonator that the purpose of this utility model is to solve the prior art PlayGear Stealth to acoustic reflection after defective such as sound wave stack generating unit branch phase place confusion, and provide a kind of senior middle school bass effect preferable, each frequency tone chromatograph is inferior clearly demarcated, and tonequality is inner ear formula PlayGear Stealth preferably.

The utility model solves above-mentioned technical problem by the following technical programs: a kind of inner ear formula PlayGear Stealth, comprise shell, described shell comprises base and loam cake, also comprise be enclosed within described shell front end can fill in earphone silica gel sheath in the duct, by airtight resonator of forming of base and loam cake and the ear handle that is connected with a side of loam cake, be provided with the audible component that the signal of telecommunication is transformed into the sound wave signal in the described resonator, end at ear handle extends the signal transmission line that is connected with this audible component, and described resonator is the wooden resonator of a drum shape.

In the utility model, described base, loam cake and ear handle are wood materials.

In the utility model, described ear handle is cylindrical.

In the utility model, the lower end of described ear handle is provided with the metal finishing cover.

In the utility model, described wood materials adopts maple, cherry or sandalwood timber to make.

In the utility model, the wooden resonator of described drum shape is a wooden resonator of drum shape that seals up and down.

The utlity model has following advantage:

1. the utility model is complete wooden PlayGear Stealth, and a drum shape resonator is arranged, and has increased the echo space of middle bass.The low more honest grace of tone color in making has effectively been improved because traditional PlayGear Stealth is subjected to the restriction of volume, middle bass reflex and the muddy phenomenon that produces.

2. ear handle of the present utility model is cylindrically to pass through mutually with drum shape resonator, and profile is succinctly attractive in appearance.

3. ear handle of the present utility model rear end is furnished with silver color or the golden yellow metallic sheath of handling through special process.This gold, wood match, and add wooden natural colour and wood grain, embody classic graceful aesthetic feeling.

4. material of the present utility model adopts maple, cherry, sandalwood high-quality timber to make.The earphone that acoustical quality is made than traditional plastic material is good a lot.The tradition PlayGear Stealth all adopts the plastic cement injection moulding.Because volume is little, the echo space is restricted, middle bass sound reflecting and make both poor sound quality.

5. the above timber of employing of the present utility model, wooden density height, wood grain are attractive in appearance, the more important thing is that wood fibre has good absorption characteristic to sound, greatly reduce the reflection amplitudes of sound wave, add the sympathetic response effect of drum shape echo chamber and cylindrical ear handle sound guide tube.Tonequality is honest, soft, clear layer, is a kind of high-grade art work and appreciates the elaboration that high-quality music combines.

Description of drawings

The utility model is described in further detail below in conjunction with drawings and Examples, in the accompanying drawing:

Fig. 1 is the perspective view of the utility model reality;

Fig. 2 is the cutaway view of Fig. 1.

Embodiment

As Fig. 1, shown in Figure 2, a kind of inner ear formula PlayGear Stealth described in the utility model, comprise shell, described shell comprises base 2 and loam cake 3, comprise that also being enclosed within described shell front end can fill in the interior earphone silica gel sheath 1 of duct, by base 2 and the loam cake 3 airtight resonators of forming 8 and the ear handle 4 that is connected with a side of loam cake 3, be provided with the audible component 7 (as loudspeaker) that the signal of telecommunication is transformed into the sound wave signal in the resonator 8, end at ear handle 4 extends the signal transmission line 6 that is connected with this audible component 7, resonator 8 is the wooden resonator of a drum shape, the wooden resonator of this drum shape is a wooden resonator of drum shape of sealing up and down, base 2 and loam cake 3 are glued together, the echo space of bass in can increasing like this, the low more honest grace of tone color in making, middle bass reflex and the tonequality muddiness that produces have been improved because traditional PlayGear Stealth is subjected to the restriction of volume effectively.

Wherein, ear handle 4 is cylindrical, and the lower end of ear handle 4 is provided with metal finishing cover 5.Cylindrical ear handle 4 connects together with drum shape resonator 8, the effect of empathizing, and also tonequality is honest, soft, clear layer, and profile is succinctly attractive in appearance.

The rear end of ear handle 4 also is furnished with silver color or the golden yellow metallic sheath of handling through special process, and this gold, wood match, and add wooden natural colour and wood grain, embodies classic graceful aesthetic feeling.

Further, the material of resonator 8 described in the utility model, base 2, loam cake 3 and ear handle 4 adopts maple, cherry or sandalwood high-quality timber to make.The earphone that acoustical quality is made than traditional plastic material is good a lot, and wood fibre has good absorption characteristic to sound, greatly reduce the reflection amplitudes of sound wave, and owing to adopt above timber, wooden density height, wood grain are attractive in appearance, are a kind of high-grade arts work and appreciate the elaboration that high-quality music combines.

The above is a preferred embodiment of the present utility model only, is not limited to the utility model, and for a person skilled in the art, the utility model can have various changes and variation.All within spirit of the present utility model and principle, any modification of being done, be equal to replacement, improvement etc., all should be included within the claim scope of the present utility model.
