Problems solved by technology

While this arrangement has proven effective at presenting appropriate sound performance while being sufficiently small and light enough for the everyday consumer user with a variety of activities, it will be difficult to hear over most, if not all, of the typical consumer hearing range. Generic (i.e. non-custom) in-ear headphones that provide good sound fidelity on the earbuds and are suitable for high-volume manufacturing present a challenge, especially in terms of packing multiple drivers inside the compact confines of the earbud housing

Embodiment Construction

[0023] In this section, we will explain several preferred embodiments of the present invention with reference to the drawings. Whenever the shapes, relative positions, and other aspects of the components described in the embodiments are not clearly defined, the scope of the present invention is not limited to the components shown, and the components shown are for illustration purposes only.

[0024] From figure 1 Initially, it is an exploded view of a two-way earplug with a first driver housing or housing 2 and a second driver housing or housing 4. At the back is the earphone housing 1, also called an earplug cup, which may be made of a relatively rigid material, such as molded plastic. Headphone housing 1 can be used to accommodate different versions of multiple driver components, including one with two driver housings 2, 4, and the other with three driver housings (see Figure 2A ). It is also used to encapsulate cables, the proximal end of which terminates in the jumper circu...

Abstract

A first driver housing and a second driver housing are positioned inside an earbud cup. The first driver housing has a rear side, a front side, a top face a bottom face, and a sound output tube extending from the front side. The second driver housing has a top side, a bottom side, a front face, a rear face, and a sound output opening formed in the front face of the second housing with essentially no tube extending therefrom. The rear face of the second housing is disposed a) adjacent to the front side of the first housing, and b) behind an exit of the sound output tube of the first housing. Other embodiments are also described and claimed.

Description

[0001] The embodiment of the present invention relates to a headset fitted in the ear canal of a user, also called an earplug, which has a crossover network and multiple speaker drivers. Other embodiments are also described. Background technique [0002] Since in-ear headphones or earplugs can deliver appropriate sound quality, while having a convenient, compact shape and light weight, they continue to be popular. Professional quality in-ear headphones often use balanced armature drivers, which can be designed to faithfully reproduce low-frequency or high-frequency sounds. However, balanced armature drivers usually do not work consistently across the entire audible frequency range. To overcome this limitation, it has been proposed to use multiple balanced armature drivers within an in-ear headset. In that case, a crossover network is also provided to divide the frequency spectrum of the audio signal into two regions, namely, the low-frequency region and the high-frequency regio...
