Abstract

PURPOSE:To listen to sound such as music by providing plural louvers rockingly in front of a speaker cone in a speaker box to adjust the direction of the louvers and to give the directivity of sound in the direction of a head of a driver. CONSTITUTION:Plural longitudinal louvers 18- are provided rockingly in the front section of the speaker box 172 apart left and right, and plural lateral louvers 19- apart up and down are provided rockingly at the rear side of the longitudinal louvers 18 and in front of a cone 174. Thus, the sound generated from the speaker 17 is transmitted by adjusting the longitudinal and lateral louvers 18, 19- while changing the direction of an opening section 171 in the direction of the head of the driver, allowing to give the directivity in the direction by changing the direction of the louvers 18, 19. Thus, the sound is led to the head while suppressing possibly the spread by means of the louvers 18, 19, and music on radio reception or the like is enjoyed even during the driving of a motorbicycle.

Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to an improvement in a speaker device used in a motorcycle.

Motorcycles are often equipped with radios, cassette recording and playback devices, etc., and can be listened to during long-distance cruising. In such motorcycles, the above-mentioned devices, including the speakers, have to be installed in the front seat due to space constraints.On the other hand, the driver's head is positioned behind and above the speakers when riding and driving, so there is no direct connection between the speakers and the rider's ears. There is a height difference between the speakers and the driver, and although the distance between the speaker and the driver is short, the sound is diffused, and the level of highly directional high-pitched sounds decreases near the driver.

The present invention has been made in view of the above.

An object of the present invention is to be able to send sound emitted from a speaker to the ears of a motorcycle driver in a directional manner, and to effectively use a sound device attached to a motorcycle. To provide a speaker device for a motorcycle, which enables a person to listen to sounds according to the riding posture and physique of a person, and enables enjoyable and effective listening to music and other sounds.

In order to achieve the above object, the present invention provides a speaker device installed around the steering wheel, in which a louver that can be adjusted horizontally and vertically is arranged in front of the speaker cone in the speaker box, and the direction of the louver is adjusted to produce sound. It is characterized by providing directivity in the direction of the driver's head.

Next, a preferred embodiment of the present invention will be described in detail with reference to the accompanying drawings.

As is known, the motorcycle 1 has a front fork 3f that supports the front wheel 4 through a head tube (not shown) at the front end of the frame 2, supports the front wheel 4 in a freely steerable manner, has an engine 5 at the lower part of the frame, and a fuel tank at the upper part of the frame. 6, and further a seat 7 is mounted at the upper middle portion or rear, and the seat 7 is of a tandem type having front and rear seats in the embodiment. At the bottom of the frame, a rear fork 8 that supports the rear wheel 9 is pivotally extended. indicates a type suitable for large-displacement long-distance touring.

A handle 12 is located in front of the fuel tank of the above motorcycle 1.
A top bridge is provided to attach and support the handle,
A fairing 20 is provided around the head tube and the upper part of the front fork.

Front under guards 14 are provided in front of the steps 13 on the left and right sides of the lower portion of the fairing, and 15 in FIG. 1 indicates a meter unit provided in front of the handlebar.

The fairing 20 is as shown in FIGS. 1 and 2,
It consists of a main body 201 in front of the handle 12, side parts 202 and 202 extending rearward on both sides from the main body 201, a screen 203 erected obliquely on the front upper part of the main body 201, and the like. The fairing 20 has an inverted U-shape in plan, and has a main body 201. The side portions 202.202 surround the front and both sides of the front of the fuel tank 6. The instrument panel section 204 forming the upper surface of the main body 201 is tilted downward and backward, and a horizontally elongated radio receiver tuner 16 is disposed in the middle part of the instrument panel section 204 on the upper side. A channel selection dial 163, a volume knob 162, etc. protruding from the side are provided, as well as a cassette tape selector 164, and a tape setting section 165 of the cassette deck 16a is provided next to the tuner 16. Further, on the right panel 166, a lock key groove 168 is provided below a clock 167°, for example.

Reference numeral 24 in the drawing represents a headlight mounting angle adjustment knob provided below the radio receiver.

Speakers 1 are installed on the left and right sides of the instrument panel section 204.
7.17 is provided, and the opening 171 of the speaker 17 is fixed and faces toward the driver's head DI. The speaker 17 is, for example, as shown in FIG.
A speaker 173 is internally held at the back of the speaker 173, a cone 174 consisting of a diaphragm faces toward the opening 171, and a magnet section 175 consisting of a coil, center pole, magnet, yoke, etc. is provided at the center of the cone 174. It is being

A plurality of vertical louvers 18 are provided in the front part of the box 172 spaced apart from side to side.
．． 182 is pivotally mounted to the upper and lower walls 176 and 177 of the box 172 via support holes 178 so as to be able to swing from side to side,
Also, the louver 18 has a bin 18 behind the upper shaft portion 181, for example.
3f: provided, and each pin 183 of the plurality of louvers 18 . . . is connected by a link plate 184. Then, a knob 185 is provided on a specific part 18A of the louver 18 so as to protrude from the front surface of the opening, and by moving the knob 185 from side to side, the plurality of vertical louvers 18 are interlocked with each other through a link blend 184 to make the same angle left and right. Configure it so that it moves in unison.

On the other hand, a plurality of horizontal louvers 19 are provided at the rear of the vertical louver 18 and in front of the cone 174, spaced apart vertically, and the louvers 19 are connected to the box 17 by shaft portions 191 at both left and right ends.

An arm 194 is fixed to the specific louver 19 19A, and this is connected to a lever 195. The lever 195 is passed through one side of the box 172 to the outside and the end thereof is inserted through the slit 205 provided inside the box of the panel portion 204. A protruding knob 196 is provided, and by moving the knob 196 up and down, the horizontal louvers 19 are linked and moved up and down at the same angle.

The above speaker devices 17 are provided symmetrically with the same structure.

In the embodiment, the air outlet 21.21 is provided outside each speaker 17.17, and the air outlet 21.21 is connected to the driver's head D1.
It is equipped with a plurality of horizontal louvers 211 that change the direction of the wind by moving up and down, and a knob 2 provided on a specific one.
12, the horizontal louvers 211... move up and down in conjunction with each other. Further, air outlets 22. are provided in the left and right side portions 202.202 of the fairing 20 in portions adjacent to the front side surfaces of the fuel tank 6.
22 is established.

Similarly to the above, a plurality of horizontal louvers 221 are provided which face the driver's head D1 and whose wind direction can be adjusted using knobs 222. The air outlet 22 is an intake port 23 at the bottom of the fairing 20.
It communicates with the duct 231 that takes in air, and the duct 2
31 is connected to and branched from the branch duct 232 in the middle, and communicates with the air outlet 21 .
