Embodiment 1
[0040] figure 1 It is a perspective view showing the appearance of the earphone HP1 of the first embodiment, figure 2 It is a three-dimensional exploded view of headphones HP1. In the following descriptions, the directions of up, down, left, right, front and back are represented by figure 1 Directions specified as shown.
[0041] The earphone HP1 is a so-called earplug type earphone to which an ear piece inserted into the external auditory canal can be attached, among earphones classified as an inner ear type.
[0042] In appearance, the earphone 1 can see the main body 1 , the cylindrical sound passage 2 protruding from the main body 1 , the cord cover 3 , and the cord 4 pulled out from the front end of the cord cover 3 to the outside.
[0043] Earpieces 5 are detachably attached to the sound channel portion 2 . The earpiece 5 is made of a flexible low-rigidity material (rubber, elastomer, etc.), and is inserted into the external auditory canal together with the sound c...
Embodiment 2
[0127] In the earphone HP1 described above, the characteristic-adding speaker unit 9 is disposed (non-parallel) so that the drive axis intersects the speaker units 7 and 8 for realizing the basic characteristic (characteristic A).
[0128] In contrast, the headphone HP2 of the second embodiment is arranged such that the drive axes of the respective speaker units are parallel.
[0129] Figure 14 It is a perspective view showing the appearance of the earphone HP2 of the second embodiment, Figure 15 It is a three-dimensional exploded view of headphones HP2. In the following descriptions, the directions of up, down, left, right, front, back, and Figure 14 Indicates the direction specified.
[0130] The earphone HP2 is a so-called earplug type earphone that can be attached to an ear piece that is inserted into the external auditory canal in the inner ear type.

Abstract
The invention provides an earphone which is easy in acoustic effect adjusting and capable of bass regeneration. The earphone (HP1) is provided with a sound playing mouth capable of playing sound to the outside, a first loudspeaker unit (7) playing sound towards the sound playing mouth, and a second loudspeaker unit (9) playing sound. A pipe (11) is provided with a pipe hole communicating with two end parts, and is arranged in a manner that the sound playing from the second loudspeaker unit (9) enters from one end of the pipe hole and plays out from the other end towards the sound playing mouth.
Description
technical field [0001] The present invention relates to earphones. Background technique [0002] In so-called inner ear earphones, in which the main body is mounted inside the auricle, various structures for better reproduction of the low range have been proposed. For example, there is a bass response type earphone described in Patent Document 1. [0003] prior art literature [0004] Patent Document 1: Japanese Patent Laid-Open No. 2006-287674 [0005] The earphone described in Patent Document 1 has a channel for guiding the sound emitted from the rear side of the speaker unit so that the sound is emitted to the front side in opposite phase to the sound synthesis. This structure is called the so-called bass response type, and it is a structure that can relatively easily achieve the rich bass reproduction expected in the market in the inner ear type earphone using a relatively small-diameter speaker unit. [0006] In this structure, the back pressure applied to the diaphr...
